This thread is for dicussion of the Snapmaker 2.0 Firmware Updates.

A note about turning on the fade height with M420. I set it to Z2.0 which as I understand it is the leveling will be gone by the time it reaches Z2.0. The first time I tried printing with this turned on it did the first layer just fine but then the second layer tried to go LOWER in the Z than the fi…

I tried it a few times but ended up disabling it for the reason you just described. Something is wrong with the code I believe. All of my other printers (mix of Marlin and RRF) function as intended. It should gradually decrease the Z offset of the grid over the height specified. Another thing I neve…

Oh and by the way, the backlash compensation still has one related command commented out in the latest release so I don’t think it is functional.

[image] DroneOn: Another thing I never got an answer on is why is there a default Z probe offset shown in an M503 output and why is it there/what is it used for? @Edwin @parachvte I think it is the last probe z (and will be set to default value as every reboot). We haven’t tested the fade he…

Normally Marlin switches off bed leveling after a G28. I would like to make sure that SM does NOT ever do this and uses, for instance, RESTORE_LEVELING_AFTER_G28 within Marlin. By the way, when do we actually get the source at our disposal?

Adjust part cooling fan speed during print

The default Z offset is always there and does not change unless changed by the user. If I were to change it from M851 Z1.0 to M851 Z2.0 and save with an M500 it will remain even after a calibration is performed or the system is rebooted. It also will change the offset of the nozzle.

Here is the diff between v1.7.0 and 1.8.0 as far as backlash compensation is concerned [sm_v1.7_v1.8_backlash]

Nice find Drone. So, it will work by some kind of manual set now, but doesn’t determine the required compensation? Not a big code reader here…
