Proxxon PD230e lathe CNC threading

My little Proxxon PD230e lathe threading by CNC a M10*150. I just had some delrin for the video... I can not slow down my spindle at less than 170rpm, so the motors are running fast.but they are fast enough for a M12*175 and may be more :o) The lathe has been modified with a cnc kit, thrust bearings, turcite/carbon fiber sliders and a spindle sensor. The electronic is modified a «red» TB6560 chiniese controler. It is running under linuxcnc with several nice functions like probing, control by joypad (wireless), zero button... Next step, may be to try with a bigger lathe ;ob
