If I probe the bed after it is hot with the Metrol switch, I should get a perfect first layer every time. I've been being lazy and babystepping....
Maybe it'd be possible to use daemon.g to set the Z babystepping based on the current bed temperature? I've haven't done anything programmatic in...
Ok, installed the Metrol switch. It worked. I followed the same procedure as before - lowered the bed, moved the toolhead to the front, waited...
Left the bed hot for quite a while at the bottom, then moved it up and the offset started rapidly changing. Will install the overkill switch at...
I am doing the calibration at temperature in both cases. Variations in the bed are controlled for. The only variables left are: 1. Dimensional...
The high bed temp helps keep the PC from warping, as I don't have an enclosure yet. It also sticks amazingly well. I used to run 115C on my...
No, I mean 145C.

After further experimentation, I think the switch is in fact changing offset with temperature. I homed the Z axis with everything hot, then moved...
I got roughly these values: PLA at 230C: offset -4.8 PC at 285C: offset -4.55 Why does it change so much? Let's say the aluminum heatbreak is...
Thanks, that solved it.
Strongly disagree that calipers are easier to use... the point would be to accurately calibrate the X, Y, and Z offset of every extruder tool with...
I wish RRF could associate fans with tools and M106 Sxxx with no arguments would control the speed of the current tool's fan. Is there a way to do...
This video of an early prototype TC has nice connectors! How do I get that?!? [MEDIA]
Your bed screws might be too loose.
I don't get how the tension spring adjust is meant to be assembled.
I really love the clever mechanism for calibrating the Z offset - print something and then probe the printed object. It would be cool if the...
