Argh. I’m trying to move onto the next stage of construction, but I’ve got a small problem. The next stage involves drilling two 3mm holes in the base-plate to attach the toothed belt, but both my 3mm drill bits are broken.
In addition, I need a 1mm hex key to tighten the grub screw holding the toothed gear to the y-motor. However, the smallest hex key I’ve got is a 2.5mm. Fortunately, I’ve been able to get around this one through the use of a T6 Torx screwdriver.
Time to go non-linear, and build out of sequence.
