Anycubic Mega X Marlin 1.1.9 with BLTouch

thingiverse

Hello, I have customized the i3 Mega Custom firmware for the Anycubiv Mega X. Now you can use the BLTouch feature from the Davidramiro version. I have set the Z offset to 0. If you have mount the BLTouch holder, you can setup the Z offset by the command M851 Z+-x. For example: M851 Z-2.8 The Y offset is -24mm. I have set the mount length to 27.3mm. You can do this in Cura. See the example picture. Deactivate the even scaling for this. Be carfully by the offset settings. Your ultrabase will it thanks. The Firmware is for TMC2208 drivers. If you have the original drivers, you must change the direction in the marlin firmware. Have fun. All work on the firmware is of course at your own risk. manual for BLTouch connection: https://cdn.thingiverse.com/assets/58/ab/fd/e6/1b/BLTouch_on_Anycubic_I3_Mega.pdf Cura Settings: Start Code: G21 ;metric values G90 ;absolute positioning M82 ;set extruder to absolute mode M107 ;start with the fan off M280 P0 S160 G4 P100 G28 X0 Y10 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G29 ;start autoleveling G1 Z15.0 F{speed_travel} ;move the platform down 15mm G92 E0 ;zero the extruded length G1 F200 E3 ;extrude 3mm of feed stock G92 E0 ;zero the extruded length again G1 F{speed_travel} M117 Printing...
