Steel sheet profiles  

RE: Steel sheet profiles

This is indeed the case with Bambu Lab printers. Prusa does not check this before printing. You cannot set the type of printing plate you have in advance in the slicer either.

RE: Steel sheet profiles

I can't think what that would change in a profile as Prusa uses load-cell Z calibration before every print, so it literally touches the sheet and adjusts for any differences in thickness. I suspect all the Bambu setting does is warn you if you try printing with a material that's not "compatible" with your selected bed, though I would've thought that could happen directly in the printer using the barcodes and cameras. In fact the CORE One L build sheets have barcodes now and it was announced that the camera would be able to detect them in future, so I assume there will be a similar warning system on the L at least.

Some users have reported that they need to set a negative Z offset for the textured print sheet. Because the load cell detects the "peaks" of the textured surface, and does not know that you want to squeeze some filament into the "valleys".

My use cases for having sheet profiles:

I use textured, Cryogrip and Garolite G10 they all have different temperature profiles and adhesion properties with the same materials. Would also like to store PID's with these sheets. For example, if I accidentally print TPU on the Cryogrip without a separation layer it's almost impossible to remove so I usually used textured for that. Conversely ASA doesn't stick well to the Cryogrip so I use the G10 for that. Polypropylene only sticks to itself so need a special sheet. Would like to be warned if I have the "wrong sheet" mounted.

RE: Steel sheet profiles

I raised an enhancement request for this a week ago. Please feel free to pile on: Ability to select a print bed type in firmware and check it against uploaded g-code

RE: Steel sheet profiles

I would have added to this request, just closed. Great suggestion, as I'm playing with 3rd party plates  and their is no way to skip the sheet detection. Atleast the ignore is an option.

RE: Steel sheet profiles

Prusa really needs to hit the ball out-of-the-park on PrusaSlicer 3.0. I just saw how Bambu has recently added Z anti-aliasing to their slicer. I bet Prusa hasn't even considered it... 

RE: Steel sheet profiles

No they haven’t, it’s a 3rd party mod. I saw the video

>> Z anti-aliasing 

Question is, do I need it.

I've got VLH, which controls Z steps for a compromise between accurately representing the input geometry and print time.

Now throw in antialiasing magic to compromise some more for perceived aesthetics. 

I'm open to any improvement but this doesn't immediately scream "I-need-it"...

I think then it's really just a compromise between variable layer height and print time. I've been using variable layer height but thought this might be a better alternative.

Ah, OK. I missed "special version of Bambu Studio"
