Even thought I set the z axis offset correctly to 0.1mm, after the bed warmns up, that distance seems to have shrunk, and I am getting problems with the nozzle being too close and becoming clogged. But I don’t see any way of keeping the bed heated while running the calibration. The software automatically turns off the heat while running the calibration. Even if I start with a heated bed, during the calibration, it drops by 10-20C in temperature. Any ideas I can run calibration while hot?

Set the bed temperature with anything other than the console. Luban, OctoPrint, whatever. When it gets to temperature start calibration from the touch screen and the bed heat stays on.

You dont need to do all of that to change the nozzle offset from the bed though. This is called the Z offset. Lots of threads about it just search Z offset.

Good place to start is here,.

> You’re not missing something obvious here, but there is a way to do this. Several ways in fact. I think you’re after item 1, but here’s everything I know just in case. Touchscreen Z offset [M421 Q command](https://marlinfw.org/docs/gcode/M421.html)[M206](https://marlinfw.org/docs/gcode/M206.html) G1029 D which is a secret undocumented gcode Snapmaker added. Use the Z offset function in the touchscreen. I believe it’s saved between power cycles, and is great for quickly adjusting a z offset. It’s not as straightforward as you probably hope, but the machine stores the Z offse…
