Filament Runout Sensor without LCD

Post by KaiborgStudios » Thu May 28, 2020 1:42 pm

Currently working on adding a filament runout sensor to my M2 Rev. E.

I've find a few how to's for the wiring and the basic firmware modifications:

I currently plan to use Y_MAX. At this point in my research i learned about the need for an LCD to continue the print job once new filament is loaded. After doing a bit more googling around I found this:
https://github.com/MarlinFirmware/Marlin/issues/11281

Here's where I ran into some trouble. In the version of marlin provided by the makergear firmware selector, all of the filament runout related fuinctions seem to be missing. While following the previous guide, in particular i noticed enum.h missing as well as the entire emergency_parser function in MarlinSerial.cpp

Any thoughts on how I can make this happen?

Thank you!

I have my doubts about how well restarting a print in the middle actually works, because getting molten goo stuck properly to anything, let alone cold plastic, seems remarkably difficult, but …

Start by being able to reload & recalibrate the firmware you're using now, because if you can't do that, you'll never be able to set up a different version.

Then replace the firmware with the newest version of Marlin, configure it to work properly, then calibrate it to produce good prints. When you're happy with it, add the LCD hardware & get it working, and only only then add the filament sensor. Changing all the firmware + hardware in one giant operation will introduce a host of bizarre failures, so always make changes starting from a known-good setup.

Several folks have posted hints-n-tips about various firmware versions and there's nothing really unique about the M2's hardware, so it shouldn't be terribly difficult to swap in a new Marlin.

Good luck … [grin]
