These are all of the mods from the original design:
- Mounting the extruder on a bridge suspended under the top of the rostock. This sits just above the home position and being in the middle right above the centre of the plate also gives me the shortest possible bowden tube which I am hoping will improve response on the extruder retracts.
- Addition of 2 x 20mm fans on the hot end
- The threaded rods in the back corners and near the front smoothrods to make it easy to tighten the belts
- Another minor mod is using Einstein's heavy duty bowden ends. The original designs were weak points and could not clamp onto the PTFE tubing well enough, but with these I can use hose clamps to hang on to that tricky little sucker.
Now all of a sudden during the home sequence it will "jump up" slightly after making contact with the last Micro-switch in the home sequence.
I am glad I built one for the experience, however I would not say this is my favourite at the moment. I am yet to get a completed decent quality print.
