Just installed the probe and I’m getting a weird repeatable error. Place the probe as directed (with lip overhanging the stock), probe X/Y/Z, Z retracts to 28mm (confirmed with 25+2+1mm gage blocks) and CM shows X0 Y0 Z28. All good.
Then I send G0 Z0 in MDI, Z lowers and CM shows X0 Y0 Z0:
The problem is the bit is exactly 2mm above the material surface:
First experienced this in CM 417 (I have an HDZ to install) so I thought it might be an error in the 417 beta so I installed 416 and got the same error. Checked stock clamping and mechanical stuff and I cannot find anything that’s loose or would seem to create the repeated error. Also the exact 2mm difference has me thinking it’s a setting.
I originally noticed when my first test job didn’t cut through the stock, checked the cut depth and it was exactly 2mm shallow. After finding the discrepancy described above I probed, dropped the Z 2mm and reset Z0 then ran another test job and it worked perfectly.
Doubtless it’s operator error but it’s got me stumped. Any input is welcomed.
