New Mill Build...Can I use LinuxCNC?

You could try the moon ML34HD0L4700

They are not overly powerful (3.8 Nm) but are 7 amp and they go like the clappers!

Great, thanks for the suggestion!...I have been experimenting the last few hours and got it moving and sounding to please me for now...I did some manual test cuts to get a feel for speed and I feel ok about the max speed now...i tried numerous driver timing settings and landed on 5500 5500 500 500...it was just random settings From a driver on the Linux cnc list...I also settled on x32 microstepping (the highest setting) because it just seemed the smoothest. 20 for acceleration. I worked through several kinks with the home and limit switches, which are working correctly now. Next I guess I need to measure for accuracy and backlash.

Another issue I have is when I try to use gmoccapy the bottom part of the window is just cut off and when I maximize it it doesn’t fix the issue. No other window does this so it’s not a screen resolution problem I don’t think. Any help with that would be great.

I still have some questions on the spindle control for another day and I’m sure I will have more questions in the coming days and weeks. Thank you all for your help, it is greatly appreciated! Andy

just check what the minimum screen resolution needs to be for Gmocappy (or calibrate/adjust your screen)

Has anyone ordered from Moons before? The quality seems pretty high from just viewing their website but I don't love the idea of ordering from China. Anyone had any experience with them or the motors? Thanks, Andy

Yes, I have a couple of their NEMA34 motors. Delivery was pretty good to Australia. Happy with the quality and the accelerate at 0.5G. I think they ship for free to the US or have a distribution centre there.

I was reviewing some of their products against our engineering model last night. Their motors do not seem to have as much rotational inertia as other brands so it was hard to match our requirements.

The other industrial quality motor is from Motion King which according to my Lam Technologies distributor are used by most of his clients use but I think their MOQ was 10 units.

The main is 5 phase (AC driver) but they offer 2 phase too (i have some motors from oriental 2 phase 1.
Moons at maker fair one guy used this but for 3D printer stuff and from chinese motor IMO is the best, the drivers i dont see it yet.
Oriental 5 phase i saw for scara use
