I’d like to make a closed loop cnc controller. for stepper motors (mostly they are for servo systems). The encoders will be piggy backed to the steppers so to be retro fitted to lathes milling machines even laser cutters or 3d printers.
I have seen the results of loosing steps and it is so sad.
FWIW This range is pretty affordable – http://www.zappautomation.co.uk/electrical-products/easy-servo-closed-loop-stepper-system.html
I’d imagine you’d have a hard time bettering the price or build of those motors, but I’d be interested to see what could be done on the DIY control side.
Thanks for the link, Yes affordability That’s why a DIY solution is appealing.
