Re: DOLLY unsolvable X layer shift (I am desperate)

that is strange i was on spread cycle before the board swap.
Now i am running stealth chop again and all is fine.
Maybe bad drivers. It is strange

The scratching on the frame was just only a little at my printer.
On moving the bed by hand there was only a very small resistance in a very small area.

Re: DOLLY unsolvable X layer shift (I am desperate)

So for me there were a mechanical issue.
the y carriage slightly scratched the frame.
Using a file solved the problem.

Maybe check if there are any spots on your motion system were it is harder to move for the steppers.

Re: Yet another Dolly builder.

(Newbie question to this part - does heated bed need to be heated through whole print or just first n layers to ensure it sticks?)
It should be heated all the time.
On my mk42 it releases the PLA under 35°C

Re: Yet another Dolly builder.

A 40W 12V heater should have 3.6 ohms. A 24V 40W should be around 14.4 ohms.

Re: DOLLY unsolvable X layer shift (I am desperate)

so yesterday finally magic blue smoke :D

Should be earlier.
Now i replace the ramps 1.6 with the gen 1.4.

maybe i should not heat the nozzle and the bed at the same time :D
but the prusa mk42 uses much less energy than a MK3 so it should be fine ...

Re: DOLLY unsolvable X layer shift (I am desperate)

yeah same for me.
it is strange because normally it should skip steps as hell when the drivers are hot.
but only one layer shift happens :D
