What's the best option?

[rastamutta]

Hello!

I've been building a diy cnc and want to replace my old kit i got years ago.
Dunno if it matters but it 1,5 * 1 meter

I have
3x HN200 3451 0640 AXR08 and
3x 85BYGH450C-012B

What stepper motors would u recommend me to use?

It will be connected directly to RM 2005 ballscrews.

The stepper drivers I have are dq860ma.

and powering them are 3x 60v 5.8amp power supply

Sorry for the dumb questions, i'm new to this and don't really know what to look for in the datasheets.

Your drivers will be fine for both the stepper motors, they can handle up to 7.8A and the 60V power supply is fine as well
the first motor is 3A 22mH and a holding torque 9.3 NM
The second one 6.4A 2.5mH 6.2 or 7.6NM
the A is not important as long as the driver is able to provide it. Your driver can do
The mH is more important as this is directly related to the max RPM. The lower mH the higher the RPM so the second motor will run about 9 x faster max speed with the same input voltage on the driver.
If you need hgh speed, use the second motor.
The NM is related to the power the motor can give. Both are strong motors which I expect will run this cnc without problems.
good luck, Toin.

Thank u for the answere!

I want more speed, so I go for the low mH motors.

and thanks for the info, that's really good to know!
