Looking for old PID adjust firmware for Mk1, 3mm.  

Active Member

I have an old i3 Mk1 with the original 3mm PrusaNmk2 extruder and the 1.0a miniRambo. It's my sons printer and after some tweeking have managed to print some really nice stuff. Despite this I am in the process of changing the extruder to a 1.75mm one and will have to update the firmware. As such I was playing with the firmware updater that is part of PrusaSlicer 2.1.0. To cut a long story short I can change the firmware, but I'd like to restore the original firmware and can't find it on the Web site.

I've been trying a lot of different versions, and it seems that V3.0.3 is the last version that still supports the 3mm PrusaNmk2 extruder. Unfortunately, I need to be able to adjust the extruder heater PID but this isn't accesable on V3.0.3.

Can any one point me to the firmware I am looking for?

Hope to get a response.

Try posting in the correct section of the forum https://forum.prusaprinters.org/forum/english-forum-older-machines-prusa-i3-mk1-and-older/ otherwise you will not get help. This section is for Prusa MINI related topics. The people who are working on older machines likes yours and have knowledge on those machines will not be reading topics on the MINI... So you understand that it is more unlikely that anyone with this knowledge will come across your post unless you post it in the correct section. Hope you find your answer.
