@darookee:

After updating my CoreXY can't home. At first it reported X-62Y-123 (or similar), at the second try it reported X0Y-0.4 and now it reports X-0.0Y-100.3 after trying to home X and Y. It also reports

Error: Homing failed

These are in my config.g

M574 X1 Y1 Z0 S0
M208 X-11 Y-0.75 Z0 S1
M208 X200 Y200 Z240 S0

Could this be because of the stall detection feature? I have not configured it, so I was thinking that it will not be used…?

I have the same homing issue on coreXY. After some digging around, I think that the issue creeps in the code where the endstops are checked.
In DDA.cpp around line 1270 the function is returned and part just below it which sets the homed axes is never invoked on a platform that shares drives:

if (endStopsToCheck == 0 || kin.QueryTerminateHomingMove(drive))
{
	MoveAborted();									// no more endstops to check, or this axis uses shared motors, so stop the entire move
	return;
}

I may be smoking something, but that is the only location that I could find where the AxesHomed bits are set. After removing the return, the axes homed like before (barring everything else that might now be broken )

@andreduplessis:

I found that by heating my bed to 110C+ (the glass transition temperature of ABS) the parts becomes easier to remove.

you mean after the print has finished?

Yes, you may destroy the print, but it requires much less force to remove it.

@whosrdaddy:

Anyone has had success with ABS? I have tried white opaque PC (sanded according to instructions Whitewolf) but it sticks too well.
The print is fused to the bed and no way to get it off without destroying it. Could it be that the Nozzle temp I am using for ABS is too high (250°C) for PC?

Hi David

Thanks for all your hard work. I love all that baked in magical goodness

Something that I have picked up is that the layer duration graph on DWC gets confused when the Z-babystepping is increased during the first layer of the print. This is not something new and specific to 1.19.

This surface works really well.
