So, I was recently having problems with the sensitivity of my Smart Effector. It would work fine once, and then randomly trigger while probing. Normally it would "finish" the cal, but return useless values. Other times it wouldn't even finish the cal.

After fiddling with the settings to no avail, I decided that it had to be electrical and I unplugged the hotend cooling fan before attempting the cal. That fixed it.

I've done at least a dozen Auto Delta Calibrations alternating with Mesh Grid Compensations with no false triggers.

Hope this helps others.

@gnydick said in Z compensation rules, when it's on, when it's off?:

And, @dc42 , my questions weren't really answered here or in the page you linked. Baby-stepping, how is it implemented? Is it a permanently applied offset that affects all of the z moves or is it just during a print.

And, it seems like applying baby-steps isn't just after the currently running command, they seem to come in bursts. I've clicked -.05 rapidly and nothing happens for quite a while, then all of a sudden, boom, they all kick in at once.

I'm not trying to be a pain, but I'm not really getting the support I need here.

Baby steps are used as a "real time" correction, usually at the start of your print. It's intended to make temporary changes to that print only, and should get reset on the next print (although I've seen my last baby step setting get carried over to the next print. Maybe it only gets reset between comps).

For example, on my Rostock, it always has a high spot between the Z & Y pillars. So even though I've comp'ed the bed, the nozzle is going to drag across this spot. To compensate, I usually click "+" on the baby steps fives times, and once the Duet is done with the segment that it's printing, it will show "0.25mm" on the baby steps. That's the delay that you are seeing between when you click and when it actually shows up.

As to its effect on the remainder of the print, yes, every layer from that point on is adjusted up by your baby step offset.
