CORE One doesn’t do a good job with pauses
Wanted to print some nameplates with magnets inside so I added a pause at a layer and the CORE One did not do a good job of going back to the right layer. The layer over top of the magnets is too low and the nozzle was constantly scraping the print.
The core one lowered the bed by a huge amount for me to add the magnets, then it cooled the nozzle down and waited. In contrast, my MK4S just simply parked the extruder at the back corner, kept the nozzle hot, and barely raised the Z height. It produced a beautiful next layer and never struck the nozzle. I think this will need some tuning in a future firmware update
here’s a picture of my CORE One on the next layers before I stopped it
And here’s my MK4 (like butter!)
Here is how far down the bed goes so I can add the magnets. I get it needs to do this because of the bar, but I want it to go back properly.
RE:
This seems like something that can be fixed in firmware. It may be worth opening a case on github as Prusa team members don't participate here but are quite active on github.
Edit: fixed github link

Yes - deffo get this up on GitHub please!

RE: CORE One doesn’t do a good job with pauses
On it. I've never posted an issue in the github before, lets see how this goes. Good thing my day job is dealing with bug reporting.

Can you share the github link when you are done. This problem is similar:
RE: CORE One doesn’t do a good job with pauses
I'll comment in that other post too.
RE:
I think I may of seen a similar issue with someone printing a bunny eared maraca on Reddit. Paused to add rice and then the print re-started too high resulting in failure. Thermal shrinkage from the rice 'stealing' the heat from the lower print was suggested. This may be unrelated but thought it worth mentioning.
Cheers 😘
RE: CORE One doesn’t do a good job with pauses
Just in case people follow here but don't get notified from github, the case there has been updated and acknowledged by CZDanol at Prusa:
Hello, guys, we have identified an issue that I believe might have been the cause for your problems. It will not get into 6.2.2, but I will suggest putting it into 6.2.3, if there will be one. Internal ticket: BFW-6825
RE: CORE One doesn’t do a good job with pauses
So there is indeed a 6.2.3 firmware now, and it includes a fix for this issue. Now all we need is a firmware release for the Core One...
RE: CORE One doesn’t do a good job with pauses
You can check in your printer settings under advanced "use firmware retraction" and make sure it is switched off. That did the trick for my old MK2.5s, which I just replaced with a MK4S

Hi all
Same and similar issue here on my new CoreOne.
It appears when i include the pause though the slicer, to setup a filament change because of colour change, insert some magnets or even when i press pause randomly on the touchscreen during the print.
In my opinion it is reproducable. Every time i used the pause, the printer get somehow lost of the correct "orientation". Sometimes more worse sometimes less.
One time after pause, even the nozzle set up too low and crashed in the print.
Maybe there is a homing missing?

RE: CORE One doesn’t do a good job with pauses
I just had a print on which the filament runs out and i had to change it. Inserting the new filament was no problem and the print continuous afterwards perfectly with no layer shift or similar.

It's a bug in the firmware: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/4505
