I'm not sure if this question should be asked here or in the servo & driver forum.
I have a working CNC router using steppers but I want to learn about servos. I have decided to build a small 12x12 CNC just to do PCBs because I do not want to change from my Porter Cable spindle to my Wolfgang every time I want to do a PCB, the PC spindle is the one that is usually mounted.
I have 2 of these servos:
I understand they are pretty weak but for learning purposes they should do. I need to know what encoder I should buy that works with Mach3. I'm not sure if the encoder and driver have to be matched or not.Globe Motors, 537A250, 30.3VDC
The encoder is an HP HEDS-5505-G06
The motor has a no-load speed of 3220 rpm @ 30 VDC & no-load current draw of 0.25 amps. At 20 oz-in the motor runs at 2840 rpm and draws 1.95 amps
I also want to build my own driver but I'm not sure which open source design I should use. If possible I want the driver I build and the encoder I buy to be compatible with an upgraded servo should I decide to upgrade.
Can I use ACME threaded rod with servers? I want to upgrade my bigger router's screws to 5 start and use the single start screws on the smaller one.
Thanks for the help.
