Hallo, i am running a uc400eth with version 1.2047 and today i did a facing operation, where I needed to to pause and continue again.So i stopped the cycle when the mill was on the lower side about 50% in the program, did some jogging outside the stock (kept z-height) and pressed run from here.

Then i got the "initial movement preparation" dialogue, switch spindle on first was checked. but when i hit ok, the machine began to move and at the same time stared the spindle.
without dwell time, so the spindle was not up to speed yet.

I have the included the cnc file (small file 170 lines)
The weird thing is, i tested this in the demo and one time it did dwell correctly. :/
but mostly not, so i guess its a bug.

Even with dwell on it fires up the spindle and makes its initial move. I've gotten used to it and I make sure I'm at max Z height before I hit run and I back it up enough lines to make certain I'm in already carved area.

So it is a thing for sure.
