General Mach Discussion / Lost Z axis
« on: February 14, 2008, 06:14:14 AM »
Hi all it's been a while since I have had to ask for help on this forum.
I have a home built router table with a Xylotex three axis kit that includes XS-3525/8S-3 stepper drive board, 3 x 269 oz in steppers and power supply.(Running Mach 3 as an operating system of course)
I have been running this set up for just on one year and now, just as I am starting to get some good paying jobs it has let me down.
For some unknown reason the Z axis (although working perfectly on screen) has decided it will not move up or down. when attempting to jog the Z axis the stepper motor just makes a low buzz or hum but won't actually move.
I have checked all of what I think are the obvious things and by process of elimination have come to the following conclusions.
Z stepper motor works fine (tested by swapping Z and Y motors)
All wiring and connections appear to be correct
Stepper drive board replaced with new one (this just made matters worse, all three stepper motors would hum but not move) Put original drive board back.
All computer leads and connections checked.
I am finding this so strange as everything was running fine on the last job I cut and I have changed nothing since.
If anyone can offer a solution or suggestions I may try before I get buried under the work that is piling up I would be most grateful.
Many thanks
