Joeaverage, Still not sure of the answer.... If my motor takes 2v, why would the torque curves reference a 60v supply? I understand E*I=W, but..... Since the power supply has the amps needed, voltage...

That's a fact!!! Do X. NO!! do Y. You both are stupid, do Q......

Yes. I had been looking for a reason for a lack of speed since day one and then I hit a post on here that mentioned inductance as the problem. It's the only place I have ever seen any mention of it....

Woo Hoo!! What a difference a low impedance motor makes. I went from 60 IPM to 250IMP, way more than I will ever use. One last problem.... The Y axis screw is making some weird noises, so I need to...

Yes they would have, had I seen them. The only downside is they ship from China, so it would be awhile before I got them. You just can't do enough research........

With any luck (ha ha), I should...

I ordered 3 of these. 3.5mh on inductance. 34HS31-5504S. We will see what happens when I get them.

Acceleration is NOT the issue. I can set it at whatever I want without issue, however, I never went above 5 because of the torque on the system.

The issue is it will move a bit and then stall. At...

I walked through everything. The bearings were a bit loose, so I tightened them a touch and it went from 55 to 60 IMP.... Woo Hoo!! Again, it's on all axis'

I have been playing with it for a couple of week now. Changing steps, m3 settings, etc. I have not changed the amperage yet. I did read someplace where that my be an issue to. Maybe if I drop it down...

Duplicated previous post.

And accel is not the issue, just random stalls. Load does not matter. Just moving or dragging my butt around, it either stalls or does not.

Ger21,
Of course!!! It is 2020 after all!!! I have found a few with the lowest being 5.5mh. That's half of what I have now. I have been searching for a small 34. The ones I have are 118mm and stick...

It APPEARS!! in M3, 1 is 1 second to max and 1 second to 0. 2 is 1/2 second to max and 1/2 second to 0. The issue is not with starting. It's mid move. It drives me nuts!!

I am confused. I looked at one stepper and it said 2.2v on one page and 60v on the other. I know my driver is supposed to auto configure to the motor, but I am not sure what they are talking about....

JoeAverage,
Lower than 2.2mh? Wow, I have seen any of those, yet.

Ger21,
JoeAverage said 23's would be fine and you are backing him up in the bigger is not always better position. The one you...

The one I found on ebay (KL34H280-45-8A) is 640 oz-in and 2.2mh in parallel. That would give me a lot more speed than I would ever need.... Unless I was launching something into space. I am still...

Inches?? If I remember right, Mach3 says 1 or 2 seconds to full speed.

I did find a NEMA 34 which should bolt up to the machine as is with 5.5mh of inductance. I still need to look at the rest of the spec's but in my little mind 5.5 is half of 11, so I...

The machine work area is 32x51 +/-. It's about 3'x6' and all aluminum. Of course it is 3/8 plate and 1x3 bars. It is one heavy beast. The axis moves easy enough if the screws are detached.
The...

That is what I was afraid of. Any thoughts on a decent NEMA 34?

I am new to CNC routers, so I hope my question is not too stupid. My CN will not go over 60in/min on any axis without stalling. I have no idea what I am doing wrong, so I am hoping someone can help...
