Ok so after thinking I was ready to order my electronics, which were this:
- Arduino with CNC Shield and A4988 Motor Drivers
- 12v 30A power supply
-
What I thought were 12v 270 oz-in Stepper motors
The real confusion lies in the stepper motors. I assumed they were 12v when I took a quick glance at the page here:
Nema 23 Stepper Motor 1.26Nm 2A 4-wires 6.35mm Shaft DIY CNC Router Mill XP9 | eBay
But when I was about to purchase, they were 3V 3A, and I dont understand how 3V would get me 270 oz-in of torque.
So my question is, is there something particular that low voltage stepper motors are bad at, or should i just use them. Also, since I purchased a 12v power supply, how do I get the drivers to run at 3v, is that a setting in GRBL I just change or am I missing something?
Thanks in advance!
