General Mach Discussion / Re: Z axis inconsistent movement

« on: September 09, 2020, 03:17:47 AM »

I have set up as you suggested and I only run the Z10 Z0 code 20 times without moving the block as my problem is consistently creeping up. By using a feeler gauge the result had about 0.05 error so average out it had about 0.0025mm error each time it run.

with the same setup, Z5 Z10 Z0 code made almost no error as I do not have a feeler gauge small enough to fit the gap if there is any.

I think Graham may have solved the mystery so lets hope the cure is a simple fix.

Which motion controller are you using ?

What make and model is your stepper driver for the Z axis ?

Perhaps one more test you could do is zero your Z axis to a gauge block (any solid block would do) – carefully slide out the block – run your test 100 times – slide in the block – measure the gap with feeler.

This would verify the integrity of your dial indicator.

Mach3 likes to be installed - as you have discovered, copy and pasting the Mach3 folder does have it's problems. Could you perhaps restore to an earlier save (from your .xml backups folder) ?

What are the Acceleration and Velocity figures you are currently using ?

Try reducing your Z axis Acceleration and Velocity (in motor tuning) by 50% and apply the changes. Does the problem still occur ?

Yes.

The Mach 2/3 .txt files will run on Mach 4.

Just a note...
Z zero is usually set at the top surface of the work rather than the table surface. This way +Z is above the initial work surface and -Z is below the initial work surface.

A touch probe is used to set to set the tool in relation to the work surface (usually Z zero at the work surface) so Z homing is not required.

Unfortunately I have no other suggestions other than perhaps thoroughly check all your cables and connectors for damage and also check your PC and control box for dust / contamination.
