Afternoon All,
I wonder if anybody could help me with an issue I'm having setting up my new DIY CNC?
After about a year of this project being on the backburner I finally got around to finishing it; it's your basic 3 axis diy cnc setup with a high speed router and a parallel port interface. I have six 8 wire steppers (two per axis) connected to a board which has four outputs per axis (wired for torque rather than speed).
So, to the problem, once I got everything hooked up and configured in mach3 is that two axis run smooth as butter and the third is jumpy, weak and very noisy!
I did a fair but of goggling before posting here so these are the steps I have taken so far:
Slow the axis right down and other motor tuning; still just as bad.
Swap to motors over to eliminate a motor / wiring issue; whichever axis I hook up to this output has the same problem.
Reflow soldering on the section of the board related to this axis. Some joints looked a bit dry and a few needed a little extra solder; but no improvement.
Reflow the whole board right from the ports to the outputs; no improvement.
Any advice much appreciated.
Thanks, Alex
