I’m wondering why the Jonaskuehling Greg’s Wade extruder used on all Lulzbot printers mounts the stepper motor at a 25 degree angle. Is there any technical reason to do so?
The reason I ask is twofold:
- The one on my AO-100 is delaminating and I need to print a replacement
- Because the motor is rotated, the X axis endstop is not adjusted as near the left side as it could or the motor would hit the leadscrew. This causes X home to start about 1/2 inch (13mm) from the side of the glass. In effect the print size is not 190mm wide but 185. I witnessed this first hand when printing tonight and the skirt printed past the glass bed at the far right. It would have needed that 5mm. (the part was fine)
If I put the motor “straight” rather than slanted then I can salvage the 5mm I’m missing.
I also notice that the small gear and the large gear rotation axes are aligned horizontally. If I were to offset the small gear toward the bottom would there be any problem? I believe that’s what 1013 did with his TAZ dual extruder so I’m guessing it would not matter…
Any thoughts welcome.
