SV01 PRO OMG Extruder Adapter

My SV01 PRO extruder gear wore down & started slipping very badly after the first couple of months of printing so I decided to upgrade to a new extruder. I picked the OMG extruder based on the data from this CNC Kitchen video. 

I printed the bracket with 50% infill in ABS but PLA should be just fine. 

Hardware needed:

• 4x M3 nuts
• 2x M3 x 16mm Screws
• OMG extruder F1 OMG V2S

Installation instructions:

• Fully disassemble extruder. Do this by removing the CR-Touch, hot end fan, head sink, extruder gear (my gear needed to be pried out of the cast extruder frame), extruder body.

• Once fully disassembled remove the three larger screws from the extruder assembly bracket. Thread the extruder stepper wires through the opening on the bracket.

• Re-attach extruder assembly bracket. 

• Cut PTFE tube to 25.5mm. Attach PTFE tube & fitting. 

• Assemble OMG extruder to stepper motor. Only use two of the included screws to attach. Confirm the orientation of the stepper connector matches the image below.

• Attach cast extruder frame & 3d printed extruder bracket to extruder assembly bracket. Use the two M3 x 10mm screws that come with the OMG extruder.

• Attach the stepper motor assembly to the 3d printed bracket. Use the two M3 x 16mm screws & the two M3 x 6mm screws. Make sure the PTFE tube is aligned with the filament guide in the cast extruder frame. 

• Change the pin-out of the stepper motor connector to reverse direction. I switched the outside wires with each other & the inside wires with each other. 
  • This video shows how to change the connector: 

• Remove the split washers from the two long black bolts (the bolts are just slightly too short with the washers)
• Re-attach extruder head sink, fan & CR-Touch.
• Tune e-steps & linear advance.
