Thanks everyone for the comments on my endstop! Maybe I'll get around to revising it one of these days. Finally got the i3v calibrated half-decently and printed out a calibration cube last night. Aside from my steppers running a bit warm (which I'll adjust the pots for) it ran very well. The overall speed was a bit slow (around 20 minutes to print the cube) so I will be playing with that in the next few days...
