Apologies if this has been answered somewhere else. I did search the forums but didn’t find an answer. I am trying to install Marlin 126.96.36.199 on my original Lulzbot Mini. I modified my Mini to have an E3DV6 1.75mm hotend along with a Titan extruder. I, therefore, need to make adjustments to the Y minimum position among other things (e.g. inverting the extruder direction (which I realize can be done with hardware instead)).
I reached out to tech support to ask them if they had the Marlin firmware files which could be edited and flashed with Arduino to the machine but they said that “the simplest way to flash your firmware is through Cura or manually by downloading the hex file.” and that “Any changes to firmware is unsupported…don’t change your hardware or software…blah blah blah” despite the fact that an earlier version of the Marlin firmware files came with the original flash drive which accompanied my machine (e.g. http://download.lulzbot.com/Mini/1.04/software/firmware/Source/).
My main question is does anyone know where I can find these files? Tech support did point me to these files https://code.alephobjects.com/diffusion/MARLIN/,however, I am not sure which of the branches is 1.18.59. This one https://code.alephobjects.com/diffusion/MARLIN/browse/upstream_1.1.8/?
Also, I am wondering why there is a .config file with the .hex files (which can be flashed through Cura). Is the .config file simply the configuration.h file which can be flashed with Arduino or is there a way that the .config file can modify the .hex file which I am unaware of?
Any help with this would be much appreciated. While I am impressed with how quickly tech support responded to my questions, I am underwhelmed by the fact they are selling a printer which runs on open source firmware, is well documented and basically designed for modding but tell you to get lost if you ask them how to flash the latest firmware in a format which could have been modded.
