Z0 not repeating

[masbobso]

Hello everyone, I've got a Masso G2 for a small Lathe, all its doing is facing a hex bolt, my program has a infinite loop at the end, but after about 6 or 7 parts it loses Z0 and completely misses the face. So I have to rehome it and start again.

Anyone have any ideas on what could be going on.

Thank you, Bob

I can think of 3 different failure modes:

• Software issue in the controller
  
• Tool has moved in the tool holder
  
• Stepper motor has missed a few steps under load
  

To confirm/deny it is a software issue I would do the following:

• Calibrate the lathe and tool
  
• Cut one bolt but leave it in the chuck
  
• Run another 10 "parts" with the cutting tool just cutting air
  
• Cut a final bolt to see if the error is present (equal to having cut 10 bolts)
  

If the error is present then you need to e-mail Masso directly (https://docs.masso.com.au/getting-support/reporting-bugs-and-issues)

If it is hardware related: I am currently working on writing up some notes for stepper motors after upgrading my mill (selection & tuning), should be posting it in a couple of days.

Ok, I'll try that out and see what happens.

Let you know tonight.

Thank you, Bob

Ok I tried that, and it does seem to be losing steps. so I guess I'll E-mail them,

Thank you, Bob
