I built a JGRO 3 axis table, and I have a dedicated computer with XP and Mach3 software. I followed the included motor configuration setup instructions to the letter but that didnít work so then I went through weeks of every combination of pin number assignment I could, and the best I can do is get the Z motor to turn...... but only when I press the X control! All I can get out of the other two motors is a click.
I have loaded and reloaded everything, and even changed video cards and I can print using the 25pin printer port, so I suspect the computer is not the problem.
I would really appreciate help, from anybody!
G'day Woodborer. I had similar problems when I was setting up my machine. At the risk of telling you how to suck eggs it came down to the wiring between the breakout board and the drivers. I changed all my signal wires to shielded cable and made sure they were as far away from power as possible and everything started working. It might not be your problem but if it is something that you haven't checked then it might be worth a look.
Other considerations might be the parallel port address setup in your controller software or Kernel Speed setting. Also try increasing the "Step Pulse" and "Dir" up in the motor tuning page
Thanks guys I tried the suggestions but still no good. It's driving me nuts because I have no clear testing regime. I emailed the supplier in Hong Kong but they didn't reply. Strange but true.
This thing is looking more like firewood every day.
