V3 Resets "Randomly" #651

Closed cjstangman closed 1 year ago

cjstangman commented 1 year ago

Hey All,

I have encountered my PNP resetting during the calibration process, which is really annoying when you are in the middle of something and have to rehome and start over. It is so prevalent during tool changes that I am unable to calibrate the automatic tool changer. It seems to happen as the staging plate moves when the nozzle enters or exits a tip.

Has anyone else experienced this, or do I have a bad motherboard?

Thanks.

I did experience the same thing with an V2 - version of the Lumen. Slowing it down has helped a bit so far. (max speed in code set to 6000) Or it my have been fixed by selecting a different USB port (as I had to change both)

Anyhow, it happened to me a lot before the changes, now with latest OpenPNP and the described changes it at least got less prominent.

A placeholder for a capacitor in the reset signal will be added in next mother board revision to prevent this if it becomes an issue again
