RE: Prusa MK4 & Octoprint
Sure. Hope you’re not relying on your filament sensor, or planning for any color change at layers, or using the controls on the printers LCD. Otherwise, works fine 😆

Planned color change works. Just did that about 30 mins ago.
RE: Prusa MK4 & Octoprint
Filament sensor is a joke with or without octoprint so...
RE: Prusa MK4 & Octoprint
Mine works amazing. Better than on the MK3. I use it all the time to finished rolls of filament and have yet to have an issue with it.
with mk4 firmware in its current state, the printer won’t communicate with octoprint at all, so if you’re relying on it for your filament sensor, then yeah it won’t work at all.
RE: Prusa MK4 & Octoprint
I can’t believe all the controversy regarding wether Octoprint works with the MK4 and then to what degree. What is the official word from Prusa??? I have read that it is on Prusa’s to do list. If I purchase an MK4 and i find Prusa’s firmware does not support the Octoprint instruction set or cannot send status updates back to Octoprint can I return the Mk4 for a full refund?
RE: Prusa MK4 & Octoprint
I'm starting to get fed up with this situation.
If the filament sensor with Octoprint still doesn't work before 2024, I'll sell my Mk4 and never look back.

Are you able to get timelapses to work as on MK3?

No you cannot get refund unless prusa state fully working and compatible with Octoprint and list features yhat it doesn't work on Octoprint
Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models
RE: Prusa MK4 & Octoprint
Yes I assumed that, my question was rhetorical. Interesting but for some 'mysterious' reason my Octoprint stopped connecting to my Prusa MK3S+ running firmware version 3.13.0-6873. Maybe Prusa heard me speaking ill of their support for Octoprint (just a bad joke). So far I have tried a new power supplies for the RPi, new USB cables between the Rpi and the MK3S+, a new install of Octopi (but I did restore my old config). Still it is not working. I am going to create a base Octopi install from scratch with no plugins , if that doesn't fix it then I will downgrade the th MK3S+ firmware.
RE: Prusa MK4 & Octoprint
Make sure the RPi Port option didn't get turned on Paul. Have seen that happen with other users before with firmware updates from Prusa.
RE: Prusa MK4 & Octoprint
The issue with OctoPrint seems to get some attention and maybe progress soon, see details in the bugreport on github: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/189#issuecomment-1715578694 🥳

I just got back from a developer meeting about the firmware schedule.The priority on this issue was bumped up in the previous meetings, everyone is well aware of how important this is for you all. It will likely be in the 5.1 firmware, ETA 2 months. What's almost finished is G-code streaming, binary G-code encoding, and arc-welding (these combined create massive file transfer speedups), those features will also be in this firmware release.
Sharing things just heard in meetings is always scary because unexpected problems can come up and timelines can slip (I am inflating the deadline they told me to better manage everyone's expectations). But this is clearly an important task to communicate updates on, so here I am, please don't kill the messenger (me).
If I hear any major updates on this (positive or negative), I'll try to update here again.
Not 100% sure what this will actually change regarding the OctoPrint integration, but this all sounds very promising. 👍
RE: Prusa MK4 & Octoprint
Hi, I installed a stable input shaper firmware 5.0.0 this week and tried to print a 27 min. Benchy gcode using OctoPrint. Octoprint is running on RPI4 and updated to the latest version.
The result was unsatisfiing, approx half of the hull printed with artefacts (blobs). I tryed slice Benchy STL with IS enabled (genetare 40 min gcode) and print. The result was the same. Then I contacted Prusa support, they sent me a sample gcode (22 min Hipo). Result was the same, print time was 33 minutes instead of 22! Meanwhile I tried save Hipo gcode to the USB flash disk and print again... and the result was perfect. Printed without any issues in 22 minutes. I tried print a 27 min. Benchy from USB flash disk and the result was fanatastic.
Hovewer I printed other model sliced for MK4 IS using OctoPrint without any issues.Realy strange behaviour. The Prusa support advanced the issue to their dev team.
Maybe the issue is some plugin that I using? Could anyone test this scenario and write a comment here?

Planned color change works. Just did that about 30 mins ago.
Color changes set up in PrusaSlicer work with OctoPrint because the color change command is embedded in the gcode file. There is no need for the printer to communicate this to OctoPrint. The filament runout sensor needs communication between the printer and OctoPrint. This is not happening, so OctoPrint keeps streaming gcode to the printer. And as the printer is not in control when printing from OctoPrint (as opposed to when it is printing from the USB stick) it does not pause when the filament runout sensor is triggered.
RE: Prusa MK4 & Octoprint
prusa done a great job porting over IS to Mini and fast
so maybe they can do the same for the mk4 octoprint compatibility just as fast ??
RE: Prusa MK4 & Octoprint
Thanks I checked but that was ok. I finally just imaged a new Octopi boot sd and restored my config to my RPi and all is good now.

RE: Prusa MK4 & Octoprint
I resolved the issue. It was caused by plugin "DisplayLayerProgress". I uninstalled plugin and problem disappeared.

RE: Prusa MK4 & Octoprint
BTW: a new 5.1.0-beta Firmware has been released and should work much better with OctoPrint: https://github.com/prusa3d/Prusa-Firmware-Buddy/releases/tag/v5.1.0-beta
RE: Prusa MK4 & Octoprint
I just installed it yesterday afternoon and I have had zero homing issues since. I’ve also had zero BSODs and boot cycles when plugging in the USB or trying to stream from PrusaConnect. Nice update that’s fixed a lot for me.
RE: Prusa MK4 & Octoprint
Great news. I'm eager to see which solutions they bring up the filament sensor if they're already ironing major kinks...
