CR-6 SE LGX Direct Drive Mount

2021-09-05 Modification to improve tolerances when fitting

Easy to print (no supports needed) and very stable mounting platform for the Bondtech LGX Direct Drive configuration for the Creality CR-6 SE.

I found that the sample mount provided by Bondtech was not very stable and tended to rock back and forth when retracting. This mounting platform does not do this. It also leaves room for custom fan or hotend covers as it still exposes the bolts holding the stock hotend cover in place.

Best printed in PLA for durability (PETG tends to flex too much). You will need a short piece of bowden tube from the LGX extruder to the hotend. The rest of the setup and configuration is explained in the Bondtech post:

It has since been discovered that the vref for the extruder should be set no higher than 0.5 and not 0.8 as suggested on their site. Setting it above 0.5 will strip the plastic LGX gear when there is a filament jam due to a block.

You will need 2 M3x20mm (18mm should be fine too) bolts to attach the mount platform to the bottom of the extruder.

I have very successfully printed 83A TPE with this step with retractions disabled and the filament going directly into the extruder via a very short piece of PTFE tube.
