NEMA 23 Stepper Motor Upgrade

Is there a need to up upgrade my stock NEMA 23 KL-23H251-28-4A motors for improved carving?

Do you experience any missing step issues, or any other drive related failures?

Yes, circles not circles, left side of square have moved to right, but I did find that some of the teeth on Y axis and Z axis belts are damaged.

I have ordered a Complete 3GT 9mm Belt Upgrade Kit and while I have machine apart I thought I would investigate upgrading stepper motors.

Thanks for your reply!

Have a Merry Christmas and Happy New Year.
