any way to directly test the driver?

Yes, as deckingman posted above the link there has directions on issuing commands to test each individual motor separately. But before you try and move the motors again, check the wiring.

swrightlast

@Phaedrux . As stated earlier, I checked stepper motor wiring, and have continuity from motor to board on all 4 wires (connector to connector). Anything wire wise to check?

@swrightlast said in STEPPER AND HOMING PROBLEMS:

but did have to re-pin new connector for x axis

What exactly does this mean? What did you re-pin? How did you do it? Why?

swrightlast

@Phaedrux , Had to put new connector on stepper wires (crimp on new pins), at the board end. Have continuity from motor end to board end at the connectors. I made no changes in config.g or the homex,y,z.g. It worked fine before wiring, so, to me it would indicate a wiring problem. I'm just at a loss as to what to check next.

Phaedrux

I'd probably start with re-crimping the ends.

swrightlast

@Phaedrux , Recrimped....no change (sigh).

deckingman

@swrightlast Have you tested each individual motor as I suggested? If so, have you tracked it down to either the X (alpha) motor or the Y (beta) motor or both? If one motor works fine and one does not, then you could try swapping the motors. If the problem moves with the motor, then it;s the motor. If the problem persists, then it could be the driver.

Out of curiosity, what were the changes you made which led to you having to fit a new connector?

swrightlast

@deckingman , I'll check that again. Answer to your other question: I was enclosing motor wires within the 2020 extrusion, and needed to clip the wires at the board connector to enable feeding the wiring.

swrightlast

I checked motor movement.....I get a short grunt of ratcheting noise, and NO movement on either axis.

Phaedrux

If you disconnect the belts from the pulleys do the motors spin individually using this sent from the console:

G91
G1 S2 X10 F3000
G1 S2 Y10 F3000

Do you still get any errors in the console?

@swrightlast said in STEPPER AND HOMING PROBLEMS:

When you recrimped, did you get the wire phases in the same order?

Duex2 expansion board
n
G1 S2 X10 F3000
G1 S2 Y10 F3000

Again, just a short grunt of ratcheting noise, Motor shaft appears to be alternating rapidly between forward and backward movement.

Also got motor phase error thing.

Phaedrux

Well the behaviour of the motor and the error message would seem to indicate there is a mismatched phase in the motor wiring.

Do you have the make and model of the motor to get the phase information?

You can also use this technique to find the phase pairs.

swrightlast

@Phaedrux , standard folgertech nema 17, 1.8 degree. 5kg/cm, 1.5a. checking phase now......stay tuned.

swrightlast

@swrightlast I could not get any resistance readings at all! Probably didn't do it right.

Error: M569: Driver 0 does not support mode 'stealthChop'
Error: M569: Driver 1 does not support mode 'stealthChop'
Error: M569: Driver 2 does not support mode 'stealthChop'

Does this give any clue to the problem?

Phaedrux

Can you post your config.g?

The D3 is telling it to use stealthchop mode. Which is only supported by the TMC 2224 drives on the Duet Maestro, and not the TMC 2660 drives on the duet wifi. So that explains the stealthchop error messages. So just remove the D parameter entirely.

It looks like there is either a rogue character in your config.g or a semi colon out of place. Can you upload the actual file rather than copy and paste?
