Hi guys, I received the 3 axis board and steppers (btw, thanks Jeff) and have to start building a power supply. I'm looking for some examples and schematics...
Hi Geert, A good source of info is the PDF section on Geckodrive.com http://www.geckodrive.com/ycom/documents/C163R16_power_supplies.pdf Try that. It is...
Jeff, just want to make sure I'm doing this right, when hooking up 8 wire motors, 2 pairs get tied together, right? I have the Data sheet and know which ones...
Hi Gerry, In general yes, you do take two wires and connect them together as a pair. This would happen for each phase. In series mode, the pair that gets...
Jeff, Thanks for this info. Bought a new transformer with 2x18VAC. I'll put the windings in parallel to obtain enough power. The transformer is rated 120 VA. I...
Hi Geert, I'm not sure if there is a way to change the pin configuaration in the ini file or not. When I played with EMC I did two things. The first thing I...
Ok Im a little confused. If I am using 1/4-20 treaded rod and my stepper motors are 200 step per revolution, then 200 x 20 = 4000 steps/inch right? Say I was...
1/8 steps would be 1600 steps per revolution, times 20 revolutions per inch - 32000 steps per inch. I believe steps per second is determined by your cpu and...
Your on the right track just continue. 1600x20threads per inch = 32000 steps per inch. or one step in software will be .0000312. As for the step per second...
Ok lets see if I can help, Stepper motors come in different step increments. They will say that they are 1.8 degrees, 7.5 degrees etc. If you figure that the...
Hey guys, This helped me out tremendously! I have learned a lot of what I couldnt figure out myself. Thanks for clearing that up for my ... Great group... ... ...
Hi people, first post here. I have 2 pcs, one running win200 (2ghz pc)running rhino 3d and a cleron 450 which will probably be the cnc controller. I am...
Hi, It appears as though the software you mention is a CAD program. I could find no reference to it outputing CAM type signals on their website, such as STEP...
What are the correct settings for a Xylotex board in TurboCNC for: * Pulse width * Step pin state * Dir pin state I've tried the default settings and they seem...
Hi, The board has the following characteristics: The STEP minimum pulse width is 1uS. This should be positive, or rising edge triggered. DIR needs to be stable...
Sorry for the noobish question, but on the wiring diagram for the pac-sci steppers, it refers to a and a- when wired bipolar series, but on your 3-axis...
Damn it, just looking over oyur site again, and the first question is answered in the pdf "windings example", Thanks anyway, just the second question now!...
Hi, Just to reiterate a little about your first question, As long as you keep the A's and B's separated (A# with A, and B# with B) , it doesn't really matter...
Hello, I finished the mechanical part of my CNC machine and finally had a chance to see this thing moving. I first tested one motor at the time and everything...
Hi Frank, Hmmm, I'm not sure what is going on. You say you switch the motors off, what does that mean? You switch off the VBB power supply, the VCC power, or...
Hi Jeff, ... I switch the VBB off. ... Yes, I start the TurboCNC first , then power the board (VCC) and then power the VBB. When turning off, I first turn off...
Thanks for the quick reply, I'm just getting the system wired up, I don't have any software yet, I will probably use TurboCNC, so I guess I'll contact them...
Hi, TurboCNC is a good choice. When you register it for $20.00, you get a license to the source code (written in Pascal). Thus, if you want, you can do home...
Hi Jeff, I have some more details. * I tried what you've suggested and disconnected IDC26-DB25 cable from the board, still the same. * when I disconnect the...
Hi Frank, Yes, by all means you can use a switch to activate the ENA# lines (you can snip the wire that goes between ENA#Z and GND, and place your switch there...
Hi Jeff, I will install enable switches later today and see if that helps. I will also try to reduce vref. Will let you know the results. My power supply is...
Hi Frank, Right, I remember the supply now. It's a big one. It appears to be a linear supply. Looks like it should work fine. I'll be watching for your test...
Hi Jeff, I've inserted 3 switches between GND and ENA (one for each motor). Using those switches I powered one motor at a time, with a few seconds delay...
Hi Frank, Go for it. Be aware though that if it is a problem with the supply outputting enough current(or not enough as the case may be), you may see some...
