Printer "Busy" when nothing is being printed
After being able to print for a few days, I turned my machine off and then back on and PrusaLink and Connect are both showing it as "Busy" and I am unable to print. Here are my specs, please help! This is super annoying.
Printer: MK3S plus MMU3
Rpi W2
Firmware: 3.14.1-8237
API 2.0.0
Server 0.8.1
Text PrusaLink 0.8.1
SDK 0.8.1
Frontend 3.12.0
RE: Printer "Busy" when nothing is being printed
I have the same issue I have found that pressing the reset button on the front display clears up the busy issue but now prusa connect is not recognizing the printer as having a MMU3 when I try to send files. Works fine manually just not with prusa connect.
RE: Printer "Busy" when nothing is being printed
I have been having this issue for a few months now. The fix I have found is to go to the settings on the printer and toggle off the MMU and then toggle it back on. Once the MMU runs through its startup process I can see my printer as "ready" in connect. The printer seems to show "busy" after power is turned off and back on most of the time and I need to toggle the MMU to get it to come back to "ready".
RE:
Tried the "MMU-Reset" aswell. sure, it's ready after this, but it looses the MMU in Connect. Pretty annoying. Do you guys have the same issue? Maybe important: I use 3.14.1 Revo FW
Only thing helping up to here is to delete printer from connect and connect it again..
RE: Printer "Busy" when nothing is being printed
Yes, the same problem here 🙁 also workaround works the same..
I was also successful with printer reset as it doesn't reset the RPi, only the printer, but as the MMU off/on is sufficient, I do that instead.

There is also this (sadly now closed) issue: https://github.com/prusa3d/Prusa-Firmware/issues/4818
And this PR for a fix (and a workaround in the comments): https://github.com/prusa3d/Prusa-Link/pull/1009
RE: Printer "Busy" when nothing is being printed
Hi, I SSH into the RPI and found the file mentioned in this post: https://github.com/prusa3d/Prusa-Link/pull/1009. The suggested strings were not found in the file.
My setup:
MK3S+ version 3.14.1 - 8237
Prusa Slicer 2.9.3
MMU2 not sure how to find the version number
Rpi:
Linux PrusaMK3S 6.6.20+rpt-rpi-v6 #1 Raspbian 1:6.6.20-1+rpt1 (2024-03-07) armv6l GNU/Linux
any suggestions are welcome.
Kind regards,
Peter
