X3 mill with rails, ATC, new motor

[Jonathan]

im looking forward to seeing how this performs,thanks for posting ;)

You're not the only one!


I finished rewinding the motor the day before yesterday, so here it is ready to varnish:




Checked the back-emf constant was correct by spinning it in the lathe and measuring the peak voltage with oscilloscope. Then powered a small light bulb with it for general amusement...




I tested the motor with my driver last night, just open loop control - will post a video if anyone's interested.


I started a job at university yesterday, so progress will be slower for now. I'll instead concentrate on finishing off the motor driver design and making them.
