Hello
While printing with my new printer, the blue extruder wheel jumped off.
Looking at the extruder, I couldn't replace the wheel until I realised that the brass driving cog had risen up, pushing the wheel off.
The cog has now been reset at a reasonable height (I think), but I had to remove the compression spring to get at the cog's grub screws.
Now, the extruder isn't pushing filament through - or is only pushing through intermittently.
Questions:
TIA

Questions:
- What height should the cog's teeth be set?
- How should the compression spring be set?
TIA
