  • Thanks for reporting the result. It's always nice to have that final message that sums up what went wrong and how it was fixed.

  • I tried to add a touch plate input for the Z axis and since Pin 10 was ESTOP, Pin 11,12,13 were the Axis HOME inputs I thought I’d use 15 for the touch plate. The LED on the PROBOTIX-125 comes on. None of the dip switches are set for extended mode. Yet the diagnostic screen won’t show that pin when it’s been assigned to Input1. Since I have both cables from the Smooth Stepper...

  • Marty, Are you sure the pitch of the lead screw is really 2.5mm and not 2.54mm? It wouldn’t be the first time someone used an imperial leadscrew and pawned it off as metric. Or the other way around. If the pitch of the screw is really 0.1” (10 TPI) then 10 revs/inch * 2000 steps/rev is 20000 steps per inch. If it’s a 2.5mm pitch screw you move 1.016” for 10 turns or you...

  • I use my JGRO CNC router. It has 5 TPI ball screws so it's reasonably fast but massive enough that if I go quickly it shakes quite a bit. I'm using 1.75mm filament with an extruder I picked up from EBAY. No heated bed yet. EBAY temperature controller. MACH3 runs the A axis as the filament feed. Better to do that in relative mode than absolute. Use a program called Slicr3.exe. It's...

  • I put an extruder on my CNC Router. I use the A axis for the extruder. I have separate temperature controllers for the extruder and bed. I was using the Coolant ON/OFF to control the temperature controllers but as soon as I stop or reset the heaters go off and that caused no end of problems. Now I manually turn them on and leave them on until I’m done. Slicr3 imports the stl file...

  • And don’t forget you still need the spindle index position. Either through a missing tooth detection circuit or an extra sensor. Most of the feedback I’ve received from people who want a high resolution quadrature encoder on the spindle want it because they’d like to be able to slow the spindle down to the point where they can stop it and reverse it and have the lead screw...

  • Russell, They are talking about threading using the $25 Darwin Plugin that allows MACH4 to run on a 32bit PC with a parallel port. The demonstration of MACH4 threading was done with an external Stepper Driver like the Ethernet SS or some such external unit.

  • For my copy of Geomatic Alibre I bought a hammer. It’s my hammer. There’s only one. I can take it wherever I want. I can use it wherever I want. If I sell my company the hammer is an asset that has value and can be sold. It’s an oddly shaped hammer though. Plugs into the USB port. And if it fails I can send it back to get it repaired or replaced. But while it’s being...

  • Thanks Andy. Maybe I was thinking of MACH2 then. I just remember a conversation a long time ago where LinuxCNC could do more than MACH as far as the number of Axis and the gantry based arm held routers. I stand corrected.
