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.

Removing that line will not affect your printer, except that it will get rid of the warning displayed on the screen.

I wanted to know [...] if there's something else to consider.

You should probably upgrade your firmware to the latest version to benefit from a couple of bugfixes and performance increases.

  • $\begingroup$ 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. $\endgroup$ – Thomas Weller Mar 17 at 13:36
  • $\begingroup$ @ThomasWeller Maybe these issues can be solved with Ask Question? ;) $\endgroup$ – 0scar Mar 17 at 18:20
  • $\begingroup$ @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. $\endgroup$ – Thomas Weller Mar 17 at 18:24
