New user here, still running into hurdles. I’m running a program that has successfully run in DCC mode on a previous part, loaded a second part and the probe fails to trigger after the alignment. I first probe 4 points to establish my Z plane, 4 points around the OD of the part to establish my X and Y zeros, do the alignment and then start to probe points for a second plane. The probe is moving vertically towards the surface but it fails to trigger. It keeps moving in the Z negative direction until it alarms out. Any help appreciated.
Thanks, Glenn
Check for magnetism in the part. Normal TP20 modules are effected by magnetic fields, and will do just that, not trigger and keep trying to move through the part.
Hi Matthew;
I will check but I don’t think it’s magnetism, it triggers properly until after the alignment. It even transitions to slow hit speed.

I checked for magnetism and there is none detectable. I also checked the axis widget and it’s aligned as required iwith the basic xyz of the machine. The probe is configured as A0 B0 and it is probe in the Z negative direction when the problem occurs. I tried to jump ahead in the program and the same thing happens.
I did more playing and it looks like it is a magnetism issue. I've never heard of this before and never had it happen on any of the other machines I have operated, although that is not many. What is the solution? The magnetism is so low that It will not attract a small screwdriver.
you either de-mag the part or you purchase non-inhibit TP20 units. Beware that this will require you do change things if you calibrate probe in a rack.
