Print & drill hole misalignment

[Zzfjean]

Hey all,

I’m having repeated issues where my print is slightly offset from the drill hole, meaning the circumference of the drill hole is only partially printed. I’ve tried a number of things;

1. Re-using alignment from drill straight away with no changes prior to printing (& being very careful not to move board during calibration cleaning process - nice and tight screws)
2. Checking alignment with the probe prior to printing - looks dead-on aligned
3. Re-doing the alignment to make sure that its not a issue with the stored alignment
4. I’ve checked that the print nozzle is nice and straight, no issues there

My only other idea is that the printer nozzle calibration process (4 switch positioning) somehow ends up with a incorrect offset when compared to the probe.

Has anyone else had this issue or have ideas on what else I can try?

Thanks - Jean

Two possibilities that I can think of.

1 - check your artwork and see if the hole is correctly lined up.

2 - was the probe seated exactly in the carriage? You said this is a ‘repeated issue’ so I do not think this is as likely.

Thanks for suggestions - yep the Gerber is good. Good suggestion on the probe, I’ll pay closer attention next print and see if there are any issues.
