@dc42 it really appeared that it's cycling at about 4Hz steadily, with or without the card in.

I unplugged all cables and actually traced the problem to something on the hot end, plugged into IO_1. Most likely the BL touch or the gyro. Unplugging that brought back the 1Hz blink and my fans powering up.

I should have checked the wiring first. Silly mistake.

@dc42 - any ideas? or just toast?

Problem isolated to thermistor, not Duet.

@phaedrux said in Z Probe Height set but Z0 is always -0.4mm off:

Well once you have your trigger height measured and saved in some way, all you need to do to re-establish Z0 before a print or anything else is a single G30 at the center of the bed.

I'd recommended process on a Delta is not a single G30 but a G32 before the print provided you do not have a G28 at the end of your bed.g

If you aren't doing some extremely high number of probe points (a S6 run only needs 10 or 12 points) it shouldn't take long and will not only set the proper Z0 but will deal with any shifting from room temp or bumping the printer.

It is easy to put a G32 in your slicers start gcode.

Seems that once I clicked on the tool in DWC it worked, even after several resets. Guess that solved it. Thanks all.

That change looks like it fixed the issue...
