Movement above 50 mm/s loud

1000, 3000, 6000 and 12000 mm/s, I dunno the order ^^

I can't really see from the video, but is that a corexy configuration? This would explain why only one motor moves for a 45 degree diagonal at least, but then both motors should move for straight X or Y movement.

It would certainly be worth checking that you are getting both sets of coils energized on your motors, and that your wire colours are consistent. Do you have a multimeter that can measure inductance?

Edit:

just saw, 1280 steps/mm? I suppose that you can do that with 256X microstepping, but is that actually called for? I'd be tempted to see if "The road greater travelled" IE: set microstepping to 16X (With 256X interpolation) and 80steps/mm was quieter.

hevilp

@supraguy I will try 16 Microsteps with Interpolation.

Why the color of the spools need to be consistent?
I thought it is just enough to have the right pairs, it isnt?

Yes you just need the right pairs.

SupraGuy

Yes, you just need the right pairs, so I did mean to make sure that they're in the same order at both connectors.

Your motors have 6 wire connectors, and you should have wires at pins 1, 3, 4, and 6. They should go to the 4 wire motor connector on the Duet in the same order.

Unfortunately there are at least 2 different wiring schemes for motors with 6-pin JST connectors on them, so the above isn't necessarily correct.

SupraGuy

I'll keep that in mind. I have only encountered the 6 wire connectors that work as I described. Thanks!

The other pinout I have come across is 1-4, 3-6. All 4 motors on my Ormerod use this pinout.

I'm right, when I say, the motor is turning right, I connected all right?

If you are able to move the motor in a controlled way in both directions, then you have connected it correctly.

Okay,

its fine than. I think its nothing with the duet. Speeds above 50 mm/s does stutter, rattle, shaking on the X-axe - carriage and I'm not able to figure it out. It was with rods and now with linear rails, too.

On the video you cannot real hear how loud it is, anyway:

Just not usable above 50 mm/s, I'm happy with any help here, the printer is jsut garbage with the sounds.
