I think I'm done with Octoprint for the most part. I upgraded my MK3s to a MK4 just recently and tried connect. It is working good. Octoprint is streaming a Logitech C922 so I can remote view but I'll be switching that out for one of prusa's cameras when it arrives.

I have seen other reports of needing to fiddle with Live-Z, but my MK4/MK4S has truly lived up to the "perfect first layer" hype. So, like Walter, I have never used the "live-Z" adjustment.

For those who need some adjustment... A method compatible with Octoprint is PrusaSlicer's "Printer, General, Z offset" setting. Obviously not "live", but if someone knows they need (for example) Z-0.03 for a specific filament/sheet combo, using that setting will adjust the Gcode itself.

So far I have never needed the live Z adjustment on my MK4. I have used several types of print sheets with it, textured and satin I use mostly, but the smooth one worked as well. Also I have used PLA(+), PETG, PCCF, TPU, TPE, ABS, ASA. No problems with 1st layer quality with any of them. I know there is something about pressing and holding the rotary knob or double clicking it at the start of the print job to get to live z adjustment, but I have never checked if that works as well when printing via OctoPrint. Apparently not all printers were created equally ...

Everything is working except progress display? Have they fixed being able to adjust the Live Z when you started a print via Octoprint? Yes, I know I shouldn't have to adjust Live Z, but there are times I need to do it for certain parts and/or Filaments. When I started a print via OctoPi I wasn't able to adjust the Live Z. As a result I've stopped using my OctoPi and switched to Prusa Connect... I miss my OctoPi, soooo much better than Prusa Connect.

Just follow the setup instructions on this page: https://help.prusa3d.com/guide/octoprint-setup-on-mk4-s-mk3-9-s-mk3-5-s-xl_646395
I have been using OctoPrint on my MK4 since it arrived in April of 2023. The only thing that does not work (yet?) is the progress display on the printer's screen like it did on the MK3S+. For me this is not an issue as I do not check the progress standing in front of the printer but via the OctoPrint interface in my browser, the same as I do with my MK3S+.

Please tell me there is some way to turn off PrusaLink username/password requirements to connect with my printer or I soon will go mad and throw the f'n thing in the trash bin!

Any updates on this thread?

Will the new firmware for the MK4/S work with USB printing so we can keep using Octoprint?

Prusa Connect sounds cool, but until it catches up with the features of Octoprint, it would be great to have other options.

This is already known. Octoprint is not fully supported yet, also the filament (runout) sensor does not work with octoprint.

I finally connected my MK4 to Octoprint. It works fine except the printer status is not displayed on the LCD. I submitted a bug report on Github about this.

I currently stopped using octoprint, I got to strange issues. It looks like the head is moving slower then it should, but the extruder extrudes as it moves faster.

So I have many strange walls, but it is not 100% repeatable.

I'm waiting for the new firmware for the MK4
