Z zero problem with adjusting

Hello all.

When i make a z zero every things looks fine, but when i after that press run.
The Z jumps up and starts at Z 21,000 mm as zero and is just cutting in the air.
Has any of you encounterd the same problem ?

Please help :frowning:

Does CM show Z=0.00 just before you press run ?
Can you post your design file and G-code for a quick check ?

Did you set zero at the bottom of your stock in your software?

Neil, I should keep a record of your statistics, e.g. “what Neil said” versus “what the problem turned out to be”. Soon you’ll pinpoint people’s mistakes before they even ask the question :slight_smile:

I wish there was a little bell I could push to make the little “ding ding…ding ding” noise… We really ought to whip up a troubleshooting guide for this…

It’s an easy mistake. You need to set Z zero at the same place you declared you would set Z zero in the design file in CC

EDIT: by the way, it’s a good habit to preview your generated G-code, I often catch my mistakes that way. Here’s an example of an online viewer, that’s where I saw you had a problem in the Z-zero setting even before opening the CC file:

The free CAMotics tool is an offline G-code viewer that is pretty popular too.
