CM 640 - Error when probing corner with bitzero v1

[RustyNailDesignCo (Bryan Knitter)]

When I tell my machine to probe corner and select the proper size endmill, it moves down, touches the block, then pulls back up, but instead of moving to find the edge, it moves back down onto the block but never stops until the z motor loses steps and errors out. “This is equivalent to GRBL error 4”.

I can replicate it and post a video if needed.

Probing only Z works fine.

Do you have the correct BitZero version selected?

When I tested this, it worked as written up at:

Using/verifying the BitZero

Here is how I check out the functionality of the machine/BitZero: first check that you have sent the correct Z-axis configuration This can be easily done by jogging down to the wasteboard surface, setting zero, then using the Rapid Position command to lift 6mm above the current zero — measure how much the machine moved — if it’s wrong: open the Log Window go to the MDI (EDIT: Note that it will need to be enabled in options in current versions) and send $$ and check that the Z-axis steps/mm …

Yes, I have bitzero v1 selected.

I ran into this issue with one of the earlier CM6 beta versions. It seemed like my Mac did not want to overwrite CM files to a later version. For me, I located the CarbideMotion6 folder, deleted it and restarted my MacBook. Then I reloaded the latest CM version. All was well after that.
