New Prusa owner. Question about sheet profiles and how z offset is saved

Hellos and stuff.  Feel free to skip:

Just got my MK3 a few days ago and I am loving it.  I had an original lulzbot mini before this, but it has seen better days and there is a recurring partial hotend plug (I think) that has been driving me nuts off and on (and I hate having to have it connected to the PC all the time).

LOVING the MK3, have not seen a single plastic zit, NO stringing, calibration cube is within +- 0.02 mm in all directions... amazing!

First post here, apologies if this has already been answered, I am having a little trouble getting good search results...

My Question:

I have read the knowledgebase article on the steel sheet profiles here, but still had a few questions.

I bought a satin sheet in addition to the smooth sheet the printer came with, and would like to set them both up.

  1. When the knowledgebase says that all the sheets are set the same at the factory, does that mean they all have the identical z offset when they arrive (including any calibration that was done to get the initial test print?)  I am really happy with the default z offset for my smooth sheet and would rather not mess with success.  Basically, if I make a new satin 1 profile, will all the other profiles still have my current z offset settings that are working great?
  2. If I switch to satin 1 profile and do the z calibration from within the LCDMenu -> Settings -> HW setup -> Steel Sheets menu.  And then later (with satin 1 still set as the current sheet) I do another z calibration (from calibration > first layer Cal.), will that z calibration save to the sheet profile or does it only save to the sheet profile if I do it from the steel sheets menu?

Thank you for your time, and apologies if it is a repeat question.

The satin sheets are about 0.4mm thinner than the smooth sheets, so definitely need a different Live Z value. 

If the default is working for your smooth sheet, don't worry, just switch to a different profile and re-do the live z calibration. The previous live z will be saved under the old profile. 

 

To your question 2, whenever you change Live Z it will automagically be saved to the current profile. No need to do anything.

 

Have fun with your new printer! I love the satin sheets and have them on all my printers. Haven't touch the smooth sheets in probably a year.

... I love the satin sheets and have them on all my printers. Haven't touch the smooth sheets in probably a year.

I hear the satin does not adhere quite as well with pla.  I often do ill advised parts with very small bits touching the build plate in places or prints with a mesh like design on the build plate which gets sliced as a TON of tiny squares all isolated on the print bed for the first layer.

I mostly got it for PETG, but will try it with pla as well.

On my lulzbot I almost exclusively printed ABS, but I have a smaller area now and am worried about ABS/ASA and fumes in here (printer is in the same room as my office) so I will probably print mostly PLA unless I need flex or other attributes.  The plan is to get a vent put in at some point, but that is not going to happen anytime soon.
