RE: The Satin Sheet Thread

As a side note I just had my first layer shift mess fail, it involved the Pinda hitting blobs of the  CF PETG I had just switched to. 16 Y crashes

 

anyway, I put the smooth back on, and found it FLC at a different # now, much closer to the satin. so, for me, the mystery shifts to mebbe the pinda moved last week while messing with the nozzle

Thank you for this detailed response!

so what is the guidance when transitioning from the PEI sheet to the Satin sheet as far as Z calibration ? do is it roughly different by .5 mm as was mentioned in the post by meicalnissyen

I don’t own the smooth PEI sheet, only the textured and the satin (which are nearly the same thickness) so I may not be the best person to reply…

Start by creating a sheet profile for the PEI sheet (assuming that’s your default) so you don’t lose the value you have dialed-in for that. Then create a new sheet profile for the satin sheet (assuming that’s your new one). Use the procedure outlined here:

https://help.prusa3d.com/article/steel-sheet-profiles_1955

Run the built in live z calibration to find a starting point for a proper z value for the new sheet. Once you have square corners and a solid flag at the end of the run, use your preferred method to fine tune and lock in the z value for the new sheet. That’s it.

I generally run one of the 75 mm X 75 mm X 0.2 mm squares from Jeff Jordan’s ‘Life Adjust Z - my way’ routine for fine tuning. You can find it here if interested:

https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/

Now you have two sheets with profiles set in firmware that you can swap between as needed and never have to ‘start from scratch’ for your z value again, unless it drifts or the nozzle wears, or you get a finicky filament, or you move your printer, or one of the million other 3D printing gremlins comes to visit 😉.

It should be that easy (famous last words) but keep you finger near the kill switch when you run the first calibration just in case something unexpected happens.

Good luck!
