This is a derivative of the super awesome Printruder II by Zaggo
http://www.thingiverse.com/thing:1980
- Incorporates a prototype design by Zaggo which allows direct access to pinch wheel - Easy flossing and access to the grub screws.
- Idler bolt is loaded at the M4 end, and then pushed towards the pinch wheel - this allows the following deltas:
- No need to dismount the motor if you want to extract the idler block
- Additional space gained allows now a 'guide' ramp for the post-pinch-wheel filament to be guided towards the heater element
- Idler block is now more secure, as it is nowhere near the insertion channel when under load
