Printing on glass
Hi,
I sometimes printed on glass with my MK3S to get a great smooth, shiny surface. That required a trick I'd found, which involved adding some gcode (basically just to tell the printer to raise the nozzle by the height of the glass piece after the probing) and quickly swapping the PEI sheet with the glass piece.
I'm wondering if this is also possible on the XL? Since there's no first layer calibration on the XL, could that still work? There's a great deal more code in the XL's custom gcodes section than on the MK3S' and I'm not sure where to put the "raise extruder" gcode (maybe at the very end?), or if the extruder will stay raised, or even if the gcodes I mean to add are valid for the XL.
Has anybody tried that?

You should not need any extra gcode on the XL, the xl probes the build plate (in this case, Glass) with its nozzle so you don't need to compensate for glass thickness

Oh so you mean that the XL doesn't probe with a magnetic sensor like the MK3S does? I didn't know that, I'll make a try on glass.
Thanks for your reply.
RE: Printing on glass
The XL has a strain gauge in the extruder frame for mesh bed levelling, that strain gauge senses pressure when the nozzle touches the build plate it doesn't care whether the build plate is metal, plastic or Glass.
before mesh bed levelling the extruder executes a nozzle cleaning exercise to ensure that the metal nozzle is doing the sensing, not the filament residue from a previous print. There is no PINDA on an XL extruder
