If your probe or nozzle fall into a hole, your print will be severely compromised. At best, the V-One will catch the error as a probing error, and at worst the nozzle will break because the error was not caught.
Probes / nozzles falling into a hole can happen for a number of reasons:
- Wrong Drill Bit used. Make sure your design matches the drill bit you used to drill the hole! Using a larger bit than specified is likely to cause your probe to fall into the hole, resulting in a broken nozzle.
- Drill file not loaded or incorrect. If there is a hole present in the board that the V-One is not aware of, it will fall in. Ensure that the drill file is loaded at the start, that the drills are the right size, and that all drills or holes are present.
The V-One will only load holes in the plated through holes / vias file. If your probe is falling into a mounting hole, that means you have a feature inside of the hole! Edit your design accordingly.
