hi
i have a weird nema 17 motors and i live outside india so i cant get any fancy motors you use.
12v
0.3 amp per phase
40 ohms per phase
28mH
3100 g-cm
6 leads

And i am using a3982
i am using a pc power supply.12v

So from what i have read that 40 ohms is too high
on my poorly (have friction and lead screw whip "wobble issues)built mantis cnc with 15 tpi i cant get more than 15mm/min

I am buildin a new cnc based on zen toolworks and my own chages to ensure least friction. what should i do with motors?
give more voltage or not.

And also i cant decide the pitch of lead screw and material for bearing. I am using direct or helical coupling,as i have access to lathe.

Please help
thanks
