Planning on a build: how to select a good driver+motor combo?

[Boyan Silyavski]

Basically the all around best combo is Toroid PSU 70V 550-600W , High voltage drivers like AM822, 3NM low inductance motors like SY60STH86-3008B Nema 23


The most economical way to build that is to buy the transformer/2x50v AC wired in parallel or 2x25V AC in series >550W for 4 motors/, then power regulator board with big capacitors from ebay to rectify it, the drivers from China aliexpress and the motors from Zapp.

0.8mm /18AWG cables 4 core shielded for the motors. I would use the same cable for the sensors and stuff. Easy to solder and strong. My first build i used thin alarm cable that alarmingly f@@@ed up. So just buy 1 entire roll is my advice.

Assuming you don't make a heavy gantry >80kg, for 1:1 driven i mean. Most of the people go with 1610 ball screw on all axis and 1605 on Z , That makes fast and and the same time with good resolution machine.

20T HTD 15 pulley is the most used, 1:1, the belts used are in the 250-310mm length area. 15mm wide , beltingonline.com

SY CABLE CLEAR SHIELD BRADED 1.5mm 4 CORE cable for the spindle to VFD


And so on
