      hi andrew, thanks for that detailed instruction, just to clarify to check the voltages here do i keep the black pin of my multimeter on no. 3 pin [gnd] and then the red one on no.1 [on and off] and any of the others to check voltages?

      Thanks Graham.

        Graham,

        If you remove the top plastic cowling over the spindle you can easily see the motor speed sensor board.  With the Camm3 powered up and the motor off:
        the left red wire is at 5.0 VDC (it's a bit hard to push through the glue on the wire)
        the center is ground, 0 V
        and the right orange wire will change from 0 to 5 V as you slowly rotate the spindle by hand

        Hi Andrew,
        Thanks for reply, just checked z zero device and that works OK, Im not sure how to check the signal from main board, I can see the 4 colour wires that go from main board to controller PCB and have a digital multimeter.
        One thing I have noticed is that Im getting no continuity on that big fuse at F3 which is a sort of merecury timer, Im not sure what its called as nothing is coming up on google to replace it.

        Regards

        Graham.

                Hi Andrew, I checked the voltages and action on the 4 pins and they do exactly as you described so the main board is OK [phew!] which leads me back to the contoller board! very frustrating!

                Kind Regards

                Graham.

                Just checked the sensor board contacts and they are OK, However I re-checked the pins from the contoller board and pin 4 is at 1.8V and not 12.5V? Graham.

                  Well that would be the problem.  Double check your measurements just to be sure. This means the main 12V supply has quit. I ll look at the schematic later

                    This means the main 12V supply has quit. I'll look at the schematic later today and suggest another couple of things to check.

                    The 12V supply is used mainly for the motor speed control and feedback. It is not surprising that most of the Camm3 would continue to work without this

                      The 12V supply is used mainly for the motor speed control and feedback.  It is not surprising that most of the Camm3 would continue to work without this supply.  The 12 V supply is generated by switching down the 35 VDC supply that drives the stepper motors.  Because your steppers still work, the problem must be in the step-down circuit.

                      On the bottom of the main board look closely at D1, R2, R3, C4, L1, C5, transistor TR1, and IC IR3M02.  See if they are burnt looking.  These are the parts of the switcher step-down circuit.

                      With the power on, measure the voltage on the left hand side of R2 and the right side of D1.  They should be 12 VDC.  Have the black lead of your meter on any ground.

                      Also measure the voltage on the top lead of TR1.  This is the emitter of the transistor.  It should be at 35 to 40 VDC.

                      Let me know what you find.

                      Just checked the sensor board contacts and they are OK, However I re-checked the pins from the contoller board and pin 4 is at 1.8V and not 12.5V?

                        Hi Andrew,
                        OK Ive checked the board nothing looks burnt although there is some goo? [glue?] at the base of L1,C3,C5 Ive noticed this on a previous Camm3 and that worked OK with this. I checked the left hand side of R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get a sensible reading off TR1 but no where near 35 to 40 volts though and this seems to connect to the metal plate? the only place I detected 12.5v was at R1.

                        Thanks Graham.

                        Graham, The problem is somewhere in the power supply circuit on the bottom of the Main Board.  It is likely the transistor TR1, or diode D1, or the IR3M02

                          Graham,

                          The problem is somewhere in the power supply circuit on the bottom of the Main Board.  It is likely the transistor TR1, or diode D1, or the IR3M02 IC1.

                          I can run through some further measurements if you like, but they are getting more involved.  The voltage on pin12 of IC1 and the voltage on the left of R74 (big resistor) would be next.

                          Andrew

                          Hi Andrew,
                          OK Ive checked the board nothing looks burnt although there is some goo? [glue?] at the base of L1,C3,C5 Ive noticed this on a previous Camm3 and that worked OK with this. I checked the left hand side of R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get a sensible reading off TR1 but no where near 35 to 40 volts though and this seems to connect to the metal plate? the only place I detected 12.5v was at R1.

                          Thanks Graham.

The 12 V supply is generated by switching down the 35 VDC supply that drives the stepper motors. Because your steppers still work, the problem must be in the step-down circuit.

                            Hi Andrew,
                            Thanks very much for your help, It will give me a head start when I speak to my electronics repairer next week, I will let you know how I get on, you must tell me what your favourite poison is and I will send you something.
                            Kind Regards

                            Graham.

[glue?] at the base of L1,C3,C5 Ive noticed this on a previous Camm3 and that worked OK with this. I checked the left hand side of R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get a sensible reading off TR1 but no where near 35 to 40 volts though and this seems to connect to the metal plate? the only place I detected 12.5v was at R1.

The 12 V supply is generated by switching down the 35 VDC supply that drives the stepper motors. Because your steppers still work, the problem must be in the step-down circuit.

                              Hi Andrew its me again! I have replaced Transistor TR1 and capacitor C4 and checked the voltages,TR1 is at 35-40V and the 12 Volt supply is a bit more than 12Volt on pin 4 and is steady. But I have since discovered that if I power up the main board with all the plugs out I am getting the correct voltage but once in I get the 12V supply dropping to 2V and it doesn't seem to be the Motor contoller board that is causing the problem as if I unplug that its still showing 2V?
                              I have a replacement IC1 IR3M02 but I wanted to check your thoughts before I tackle unsoldering 16 points at the same time!

                              Kind Regards
                              Graham.

[glue?] at the base of L1,C3,C5 Ive noticed this on a previous Camm3 and that worked OK with this. I checked the left hand side of R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get a sensible reading off TR1 but no where near 35 to 40 volts though and this seems to connect to the metal plate? the only place I detected 12.5v was at R1.

The 12 V supply is generated by switching down the 35 VDC supply that drives the stepper motors. Because your steppers still work, the problem must be in the step-down circuit.

                                Hi Andrew its me again! I have replaced Transistor TR1 and capacitor C4 and checked the voltages,TR1 is at 35-40V and the 12 Volt supply is a bit more than 12Volt on pin 4 and is steady. But I have since discovered that if I power up the main board with all the plugs out I am getting the correct voltage but once in I get the 12V supply dropping to 2V and it doesn't seem to be the Motor contoller board that is causing the problem as if I unplug that its still showing 2V?
                                I have a replacement IC1 IR3M02 but I wanted to check your thoughts before I tackle unsoldering 16 points at the same time!

                                Kind Regards
                                Graham.

[glue?] at the base of L1,C3,C5 Ive noticed this on a previous Camm3 and that worked OK with this. I checked the left hand side of R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get a sensible reading off TR1 but no where near 35 to 40 volts though and this seems to connect to the metal plate? the only place I detected 12.5v was at R1.

The 12 V supply is generated by switching down the 35 VDC supply that drives the stepper motors. Because your steppers still work, the problem must be in the step-down circuit.

                                  Sounds like you may have a bad connection somewhere.

                                  Hi Andrew its me again! I have replaced Transistor TR1 and capacitor C4
                                  and checked the voltages,TR1 is at 35-40V and the 12 Volt supply is a
                                  bit more than 12Volt on pin 4 and is steady. But I have since
                                  discovered that if I power up the main board with all the plugs out I
                                  am getting the correct voltage but once in I get the 12V supply
                                  dropping to 2V and it doesn't seem to be the Motor contoller board
                                  that is causing the problem as if I unplug that its still showing 2V?
                                  I have a replacement IC1 IR3M02 but I wanted to check your thoughts
                                  before I tackle unsoldering 16 points at the same time!

                                  Kind Regards
                                  Graham.

                                  of the Main Board.  It is likely the transistor TR1, or diode D1, or
                                  the IR3M02 IC1.

                                  are getting more involved.  The voltage on pin12 of IC1 and the
                                  voltage on the left of R74 (big resistor) would be next.

                                  goo? [glue?] at the base of L1,C3,C5 Ive noticed this on a previous
                                  Camm3 and that worked OK with this. I checked the left hand side of
                                  R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get
                                  a sensible reading off TR1 but no where near 35 to 40 volts though
                                  and this seems to connect to the metal plate? the only place I detected
                                  12.5v was at R1.

                                  to work without this supply. The 12 V supply is generated by
                                  switching down the 35 VDC supply that drives the stepper motors.
                                  Because your steppers still work, the problem must be in the step-down
                                  circuit.

                                  These are the parts of the switcher step-down circuit.

                                  I re-checked the pins from the contoller board and pin 4 is at 1.8V
                                  and not 12.5V?

                                  and they do exactly as you described so the main board is OK [phew!]
                                  which leads me back to the contoller board! very frustrating!

                                  clarify to check the voltages here do i keep the black pin of my
                                  multimeter on no. 3 pin [gnd] and then the red one on no.1 [on and
                                  off] and any of the others to check voltages?

                                  control. The motor control signal branches out to the timer, but it is
                                  not in the control path. You could remove the timer and everything
                                  should function the same.

                                  but if you can measure the DC voltages on J601, pin 1 is closest to
                                  the corner of the board.

                                  works OK, Im not sure how to check the signal from main board, I can
                                  see the 4 colour wires that go from main board to controller PCB and
                                  have a digital multimeter.

                                  replace it.

                                  "sensor" that is used for Z axis setting? You should see the LED turn
                                  on and off. That would eliminate another chunk of circuitry.

                                  works fine and the motor runs OK if connected to the mains, just had
                                  the motor controller board back from an electronics guy and as far as
                                  he was concerned it should be OK [ and it was checked ]

                                  states that after 1000 hours you can turn the timer over [ the thing
                                  that looks like a mercury switch] at F3 on the motherboard], [ I
                                  think it means that as its poorly translated Japanese] That got me
                                  wondering if because the timer has hit the limit if that is whats
                                  stopping it running?

                                    Hi Graham.  Well, everywhere.  There are a couple of things you can do... The "cave-man approach": Start "GENTALY" tugging on all the wires and see if anything pops off.  Make sure that any slip-on type connectors are OK.  Go back through all the areas that Andrew talked about and try turning on the spindle at each point and look for a drop in the voltage... Main point: Circuts can check out fine when "NOT" under a load.  You did check the switch to the spindle?  Maybe look at the connector for the control panel... Be sure there is no oil or dirt present... Use contact cleaner.
                                     
                                    Good Luck,
                                    Chris.

                                    Sounds like you may have a bad connection somewhere.

                                    Hi Andrew its me again! I have replaced Transistor TR1 and capacitor C4
                                    and checked the voltages,TR1 is at 35-40V and the 12 Volt supply is a
                                    bit more than 12Volt on pin 4 and is steady. But I have since
                                    discovered that if I power up the main board with all the plugs out I
                                    am getting the correct voltage but once in I get the 12V supply
                                    dropping to 2V and it doesn't seem to be the Motor contoller board
                                    that is causing the problem as if I unplug that its still showing 2V?
                                    I have a replacement IC1 IR3M02 but I wanted to check your thoughts
                                    before I tackle unsoldering 16 points at the same time!

                                    Kind Regards
                                    Graham.

                                    of the Main Board.  It is likely the transistor TR1, or diode D1, or
                                    the IR3M02 IC1.

                                    are getting more involved.  The voltage on pin12 of IC1 and the
                                    voltage on the left of R74 (big resistor) would be next.

                                    goo? [glue?] at the base of L1,C3,C5 Ive noticed this on a previous
                                    Camm3 and that worked OK with this. I checked the left hand side of
                                    R2 and the right of D1 and Im only getting 0.3 volts, I couldn't get
                                    a sensible reading off TR1 but no where near 35 to 40 volts though
                                    and this seems to connect to the metal plate? the only place I detected
                                    12.5v was at R1.

                                    feedback. It is not surprising that most of the Camm3 would continue
                                    to work without this supply. The 12 V supply is generated by
                                    switching down the 35 VDC supply that drives the stepper motors.
                                    Because your steppers still work, the problem must be in the step-down
                                    circuit.

                                    These are the parts of the switcher step-down circuit.

                                    I re-checked the pins from the contoller board and pin 4 is at 1.8V
                                    and not 12.5V?

                                    and they do exactly as you described so the main board is OK [phew!]
                                    which leads me back to the contoller board! very frustrating!

                                    clarify to check the voltages here do i keep the black pin of my
                                    multimeter on no. 3 pin [gnd] and then the red one on no.1 [on and
                                    off] and any of the others to check voltages?

                                    control. The motor control signal branches out to the timer, but it is
                                    not in the control path. You could remove the timer and everything
                                    should function the same.

                                    but if you can measure the DC voltages on J601, pin 1 is closest to
                                    the corner of the board.

                                    works OK, Im not sure how to check the signal from main board, I can
                                    see the 4 colour wires that go from main board to controller PCB and
                                    have a digital multimeter.

                                    continuity on that big fuse at F3 which is a sort of merecury timer,
                                    Im not sure what its called as nothing is coming up on google to
                                    replace it.

                                    "sensor" that is used for Z axis setting? You should see the LED turn
                                    on and off. That would eliminate another chunk of circuitry.

                                    into the motor pcb, pin 1? Should go from low to high, +12V.

                                    works fine and the motor runs OK if connected to the mains, just had
                                    the motor controller board back from an electronics guy and as far as
                                    he was concerned it should be OK [ and it was checked ]

                                    states that after 1000 hours you can turn the timer over [ the thing
                                    that looks like a mercury switch] at F3 on the motherboard], [ I
                                    think it means that as its poorly translated Japanese] That got me
                                    wondering if because the timer has hit the limit if that is whats
                                    stopping it running?
