Re: LC+ 4896 Motor Requirements
While we at Armor CNC don't believe that steppers are adequate for a CNC machine for many many reasons, I can still help and let you know that peak torque on those motors is 200 oz-in continuous, 1200 peak.
Match your steppers to that or exceed it and you'll be fine.
You can also do the math, if you've got 20mm pitch screws (might be 5, but 20 is more likely), you can figure out how much torque you will need at any given speed and aim for what you're looking to accomplish.
On the off chance you'd like to get the original equipment to drive that machine, we can supply all of it that you're missing, contact me here or by PM or on our website.
