As per my posts over the previous days, there is a new gantry in the works for the Gemini 3D printer.
Last night the motor mounts were printed and attached to the frame. These have a lot more strength than the previous version and have slotted holes for the for M3 bolts that attach the NEMA17 stepper motors. This will allow for tensioning the belt once it’s clamped to the x-carriage, which is the next part that will be designed and printed.
Since the photo was taken I have also printed a revision of the X-end/y-carriage mounting part which corrects the belt alignment and allows for adjustment of the x-axis – I will detail that assembly in another post.
Note that the belt path is not correct in relation to the x-carriage in this photo, it will run straight like it should once the part with the belt clamps is assembled.
