General Mach Discussion / Z axis drift during X-axis motion...

« on: November 14, 2010, 04:08:28 PM »

I'm using Mach3 with a computer running Windows XP and a HobbyCNC driver board.
I've noticed that the Z-axis motor will rotate slightly during runs on the X-axis only.
It is stable on Y-axis runs.
I'd love to get rid of the drift...
And, yes, I've already added the extra capacitors to the cables going into the HobbyCNC board to ground out cross-talk.
So I'm open to new suggestions...

General Mach Discussion / X-Axis Motor Doesn't Start After Tool Change...

« on: November 13, 2010, 03:53:00 PM »

Rough cut goes smoothly until program reaches tool change pause.
After tool is changed, I press Cycle Start...
The screen in the upper right of Mach 3 indicates the tool is moving and the numbers in the X, Y, Z axis change,
BUT the X-axis motor does not move.
I've tried to reset to a previous position with the Run From Here command, but the machine also seems to have forgotten where it was.
I'm using a HobbyCNC driver board.
This is a new problem for me...
Any thoughts, suggestions???
