General stepper motor questions

I’m setting up a rotary axis using two 4:1 pulley sets on this motor
CNCTOPBAOS Nema17 Stepper Motor 78oz.in 48mm Length 1.8A Dual Shaft for 3D Printer/Milling/CNC Router Machine 17HS8401B

Incidentally here is the physical part. Pictures next
I originally had a gear motor but it had backlash.
I am setting it up so I can lower the axis to run larger diameter stock. It lives at the back of my workspace (max Y) and pivots at the left end. I plan on mostly flat round workpieces so I’ll just bolt onto the flat face of the pulley. I used the double end motor and 2 belts.

The config file below works with other motors but this brand new motor doesn’t hold position nor does it turn. Is it dead? What else can I try? I have checked continuity of both coils and it is wired correctly.

Your $ss is not showing confirmed connection with all your drivers.

If you put your yaml on here and use the preformatted text option it is easier to read.

Have a look at this yaml for 4 drivers.

Does the motor get really hot when powered up?
When I first got my rotary it didn’t turn and it got really hot. It came with some additional short cables. I tried them and one worked. It changed the wire order to the motor.
I think the Jackpot wire order is AABB and my motor was different.

It doesn’t get hot. It’s wired AABB. The first motor got hot until I turned down the hold amps and run amps.
I’ll try and turn them up as in Ryan’s response.
Thanks

I’m pretty sure it’s a bad motor.
Thanks for your input

Please explain how you see that drivers are not confirmed.

I tried this as written and it worked worked as I expected; only 1 motor on x and y. I tried adding the other motors but didn’t get it right apparently. Is there a table showing all the pins for the 6 drivers?
Should I be able to move A? G0a360f200 or something?

I also have a possibly intermittent problem where the sd card is not recognized. I moved the sd card statement closer to the top of the yaml.

I don’t have time right now to add the yaml file or the $ss response but I will try later.
Thanks

Can you show me a picture of your full machine, I am a little unclear as to what exactly you are doing.

MPCNC with an added A axis?

Error #1

Only showing 4 drivers. If you take my MPCNC config and just uncomment the A axis stuff it should work, with just some steps/mm, current and end stop adjustments. Change less at a time. Don;t bother changing the name or anything else until it works. One change, boot, test, stray empty spaces will crash a config.

Yes, you guessed correctly. The fourth axis is parallel to Y.
Your method worked great. I used the newest config from the GitHub.
I un-commented the fourth axis parts, and then the only thing I had to do was label that section as a:
So now I have four axes when I do the $ SS List and I can move all of them. The tablet part of the web page access shows the A position.

I need to find a post processor for vectric that outputs for wrapping to a file in GRBL or gcode.

I’d like to draw in fusion but they have a additional pay wall to get wrap to rotary or 4 axis cam operations
Maybe time to learn FreeCad
