I am currently on a capstone project working with a LulzBot Taz6. We have designed and built a print head that will take two filaments and extrude them out of a single hot-end. The position of the nozzle has moved and when homing the z-axis the nozzle does not touch down on the homing button. I have tried creating my own firmware with Arduino and editing a Marlin firmware that can be downloaded at https://github.com/MarlinFirmware/Marlin . I have no experience with editing firmware. Also looking at the Marlin firmware with Arduino and saw that there was a “Mixing Extruder” option, has anybody had any experience with this?
So, I need help editing the X and Y location so that the nozzle will push down the Z homing button, and if anybody has had experience with the “Mixing Extruder” option I’d like to hear about it
