@dc42
even when I commented the P0 out with ; , it stills runs when I tested M584 X0 .
But still no motion from external drive 5 6 7 8. -

This is the similar thread but ut is locked out
https://forum.duet3d.com/topic/4935/wiring-up-external-dq542ma-stepper-motor-driver/6Exactly what I am doing but still no clear answer...
And I got 3.7V on dir- and dir+ when I was trying to home...

Have you tried using the M569 T parameters that were published in the last post in that thread?

Please do not ask me for Duet support via PM or email, use the forum

@dc42 I tried. I think my driver is bad. I'm buying new ones. I will report the results soon
Thanks so much -
@dc42
I got it to run!!!Now here is a new issue. When I run test all motors, I edited to have 32x microstepping. An error pop up saying M350 drive Z does not support 32x microstepping... what is the deal?
-
@namlecnc M350 sets the internal stepper driver microstepping (over SPI). As you are using an external driver the firmware cannot set the microstepping on the driver, you do that in some other way (normally Dip switches). If you set the steps/mm (M92) correctly for whatever microstepping you use on that external drive that will work.

@t3p3tony
Yes this is on external drivers(xyz) so m350 for xyz doesn’t matter but the m92 steps per unit (mm) is the deciding factor?Thanks a bunch!
-
@namlecnc yes. just use M350 for any internal drivers.
-
@namlecnc Can you let us know what you did to fix the issue you were having getting the TB6600 to run?
-
@t3p3tony TB6600 does not work.
I have to change to a more expensive DM542SI have it running now. At 32x , it runs ebrry time now. 128x doesn’t work.
-
I am also having issues getting my external drive to work. I attempted to wire the
+(STEP,DIR,EN) to the 5V on the Heater Pins on the expansion, to see if the voltage of the expansion breakout was too low. This did not change my stepper motor behavior (it just vibrates after a few X+1 commands.See thread here for more information: https://forum.duet3d.com/topic/7703/closed-loop-control-of-stepper-motors-with-rotary-encoder/24
-
@sean, as a follow on. ENA+ is by default at 3.35 V.
If the schematic above says >3.5 V, would 3.35V be an issue? If it were, I would imagine wiring all the + leads to 5V would have remedied my issue.
-
@sean The CL57T manual says in 3.1.1 the high mode to be 4.5 to 24 volts, low between 0 to 0.5
-
@joergs5 If this were the issue, wouldn't it have worked when I wired all of the + leads to +5V?
-
@sean I only meant it's not 3.5 volts, but higher. I don't think this is the reason. I suspect timing problems (2.5 us too short or acceleration / speed too high).
-
@joergs5 ah, thanks for pointing that out. I have the T parameter in M569 set to T10 right now - I saw a post from dc42 that said it would limit the step rate, but otherwise cause no problems. I'll leave it there for now to make sure all other things are working, and then decrease the timing later.
Regarding acceleration / speed, this is just with the motor sitting on the table, no load, and only commanding +1 mm movements. Acceleration and speed shouldn't be a factor yet.

In short, don’t use tb6600
