Mystery CNC Error - Mach3, UXC100
« on: October 15, 2018, 03:52:45 PM »
My CNC Mill has a fault and I am looking for any suggestions or ideas.
Symptoms:
Mach 3 on Windows 7, HP Laptop
USB to UCX100 and MyCNC HG08 motor controller
Mostly clicking and typing into Mach3, and also fine jogging with a
wireless MPG.
"ref all home", then G28 to place near the centre.
G54 then G0 X0Y0 puts the cutter above the centre of my job, and then X30 to put cutter above the actual cut surface
Move Z down and jog till its about 3 mm above the cutting surface, then jog up until a
4mm ground spacer fits under the cutter, and thentype 4 into Z.
Now XYZ are set to zero in the centre and top surface of the job, all sweet so far.
Z50 to get the cutter clear (there is a central bolt holding everything in place, clear that)
now pay attention please:
In the MDI line, I type G0 X30. Table starts the X move AND the head shoots up (Z), faster than normal 'fast',
then the motor fault switch on one of the driver units trips and stops mach3.
I have to switch off and reboot to recover.
I can jog with the MPG and type into MDI line to move all over the place without problem, but
repeat the setup and it mostly goes wong - i.e. its only when the cutter is down to about 40mm above the table
that the problem occurs. And only when entering G0 X0.

So any ideas gratefully received!
The mill is a Champion 20V, the whole head moves up/down, fixed knee.
I bought it (used) a few weeks ago and have made several jobs without problems
(well  many newbie errors, but all explainable), this fault is new.
Damp?
crosstalk?

Many thanks! Simon

What version of Mach3?
Do you have the latest UC100 plugin?
