Now to have a mount for the NEMA-17 motors. I’m not quite sure yet how the axle should be positioned, so I have it going over the center of the frame contour.
A Fork in the Road
During assembly I have found that I really should have a sturdier frame. So I put everything on hold to redesign the frame and print in the ASA filament I acquired, my favorite material. There is a possibility of some warping. I really hope that doesn’t happen.
Since I am printing the frame, I decided to split it in two logical parts: the top and the bottom that screw in together using standard M3 screws.
A while later, I had the top part.
During initial testing I found that the 10×10 dimension for the tubes is too weak, I will have to redesign this to use 20×20 tubes. I also found that the printing material should not be PETG, because of the nature of that material. PETG has a tendency to flex, and I want the frame to be really stiff in order not to interfere with accuracy of the head. So I will be reworking the frame in ASA filament, which I have had good luck printing in the past.
