Auto-Calibration Question.....  

RE: Auto-Calibration Question.....

Sure, the mk4 will make it easier. But it's really not a big deal with the Mk3S either. The textured and satin sheets are about 0.4 mm thinner than the smooth sheet so you want to start your calibration at about -0.400 more negative. And using s calibration model like this   https://www.printables.com/model/105404 makes the whole process a matter of a few minutes instead of going through loops of running the inbuilt first layer calibration model. 

RE:

That certainly is a big plus for the MK4.

As @fuchsr already indicated, I also don't find doing the first layer calibration for different sheets and filaments a big deal on the MK3S+. My setup is quite simple, so it was only a small investment of time to do the work and it is made easy if you use the built in 'sheet' memory.

The satin and textured sheets are thinner than the PEI smooth sheet so you will find the offset goes a bit lower. For guidance, here are the Z-offset values that I use for PLA and PETG:

PLA
Smooth sheet: -1.165
Satin sheet: -1.455
Textured sheet: -1.445

PETG
Smooth sheet: I don't print PETG on this sheet
Satin sheet: -1.435
Textured sheet: -1.425

I find PETG needs a little less 'squish' so hence the 0.02 difference compared to PLA.

In answer to your question though, the printer's load cell will automatically compensate for different sheet thicknesses, but it is unclear if a 'squish' compensation factor is applied based on the chosen filament profile or material. Someone else may be able add something on that.

Hope that helps.

Cheers,

RE: Auto-Calibration Question.....

As I've already posted about it, I'm going to just link to answer your question.

I'm no fanboy so you can expect honest unbiased feedback from me.

One thing I will say is that if you buy Bamboo you're at their mercy for parts as the printer hardware is very much proprietary.

I was tempted to ditch my MK3S+ and move to Bambu as I just wanted to print with ease. Im not a tinkerer etc - I just want to send my model across and print. 

Fortunately Ive had zero issues with my MK3S+. I hated the first layer calibration stuff, but once done, I've not been back to it and all my models have been fine. All printed via PLA - and I have lots of different colour Prusament PLA that all works fine.

However, I have been nervous to try PETG even though I have a roll of it, and even though I have the textured sheet, just because I know I have to recalibrate the Z axis all over again, and the way PETG can yield different results while printing - blobs etc. Hence why I considered the Bambu instead, thinking there is no worry about which filament you use as the printer will calibrate itself......

Now that the MK4 has auto calibration, that's a big deal for me. I'm now looking to replace my printer with the MK4, and I will be happy to try the textured sheet with PETG now, knowing I can just change filament and sheet, and let the printer re-calibrate and just do its thing - at least that's how I think it works?? As long as I select the correct filament in the slicer, the printer should do the rest irrespective of filament and sheet (as long as it is selected in the slicer of course)?
