I had a couple issues with the last firmware upgrade. Therefore I want to keep this version as long as the printer works fine for me.

@ThomasWeller Maybe these issues can be solved with [Ask Question](/questions/ask)? ;)

@0scar: unfortunately that's unlikely for my case. I first used the Prusa forum. Then I had two phone calls over several hours with Prusa support without any result. I then returned the printer in warranty. They sent me a printer back which looked like a complete rebuild.

# How to remove firmware warning

(Asked by: username_0 on 2019-03-17)

I'm operating my Prusa i3 MK3 through Octoprint. Basically, this means I can start prints from remote. However, there's the firmware version warning which requires me to press the knob and confirm that message.
I now found a line of G-Code in Printer Settings / Custom G-code which is probably doing this:
M115 U3.6.0 ; tell printer latest fw version

I'm not very familiar with G-Code yet, so before I remove that line, I wanted to know whether that's all I need to do or if there's something else to consider.
