Yes,the motors stop and thehot end drops, all the time, every time, yet this is not important to the results.
when printing the motors are always "on"
when you are leveling the print plane with the nozzle the motors should always be "on" and the nozzle "HOT" because it gets longer/closer to the print bed when hot.
look on Youtube for Jay Couture videos about calibratin and leveling the print bed by printing part of one layer of a square.
This way you can get it down to 0.02mm but only after you have done the paper test with a hot nozzle and the motors on.
Thank you. A fellow Delta guy was helping a newbe (me) to calibrate my 3DR. The he set it to go to 3mm off the bed. But after a bit of a chat it had dropped. He suggested the problem was my spindles slipping, even though they are amazingly tight, and there was vurtually no forces on the motor. We did change that motor timeout in configuration.adv.h from 60 to 400.
I was concerned that maybe my Spectra needs to be tighter? But if you say that the motor will shift a few degrees upon losing its power, I won't worry about that.
I was told that because it was doing that, he could not calibrate it for me.
So close. I've been working on this thing for 8 months. I figure I'm at 98%. I have a J-head issue to resolve, This calibration and I should be printing soon.
Thanks!

Weird, what do we do when we get advice that turns out to be misdirection? We learn?
You should be able to get within 0.1mm using post-it notes. I use mini-post-it notes. Then....
Use this youtube video and you will get within 0.02mm across a flat print plane.
