Hi - I am considering the new Leadshine MX4660 and KL34H260-60-4A for my new CRP Pro 4860 build. The Leadshine has 4 outputs at up to 60V/6A and the KL34H260-60-4A is a 465-oz/6A motor (1.7mH inductance). I plan to keep the dual X and Z motors at 5.35A via DIP switches. The spindle would be a 2.2KW water cooled. Is this a good driver/motor combination for cutting mainly exotic hardwood/plywood/corrian and some aluminum? Thanks.

Where do you even get an MX4660? Leadshine doesn't have it on their website. Google doesn't turn up anything on it. I doubt you'll find anyone who's used one, either.

Unless I'm mistaken, looking at the manual, it appears to be 3 axis.

I called and was told the configuration is almost identical to MX3660 except two extra pin (7&8) for an additional motor. They are working on an updated doc

It's not the right manual.

Awesome! Might be a good replacement for my G540.

Torque curve, I guess, for the motor from Leadshine. How much is a typical CRP PRO 48 gantry weight?

Just a quick update, I've been using this set up for a number of months, Y axis (dual motors) rapid max out at about 1150IPM and 50in/s/s accel. X axis rapid max out at just over 1200ipm and 60in/s/s. I can reliably set Y at 900ipm and 35 in/s/s, X at 900ipm and 40 in/s/s. I've cut MDF/plywood comfortably at 450ipm with a 2.2KW spindle. Motors are barely warm to the touch (@50.5V) and very quiet.

I have been using Leadshine digital drives (AM882) on my CNCRP4896 for 2+ years..(with 960 oz-in low inductance nema 34 steppers).
I really like them...When I build my Plasma table I am planing on using the new MX4660 drive/BOB...
Also note that they sell individual replacement boards for this unit if one craps out..
