Breakout board produces no 5v signals

[adavidm]

according to that spec, 3.3v should work fine.

Did you see @dc42's post?

@adavidm
Yes I have changed P1 to P5 and nothing.
I thought the drive mapping should do the job but I understand you have to assign the drive (on the break out board) in the M569 also.

@leonknook said in Breakout board produces no 5v signals:

M569 P5 R1 T2 ;does not work

The breakout board handles the inversion of the enable signal, so you need R0 in that command, not R1. If it still doesn't work, try T4 instead of T2.

No, sorry no results. Second led is pulsing but it seems there is no current at all to drive the motor.
Extra info: the stepper driver has a 48v dc connection
The attached motor is a standard nema 17 to see if it works (must be later on a nema23)

Which is the "second LED" you refer to?

After you send the command to move Y, do you get +3.3V or greater on ENA+ relative to ENA- ? It should be the other way round after you reset the Duet and before you send the first command to move Y.

@dc42

After a reset off everything I measure this -3.53v
After pushing the y move button the voltage change to plus +3.53v

The led down under is bright all the time
The led above is pulsing when pushing the move button.

Same measurement on the breakout board self without stepper driver connected.

My problem is still not solved. If there are no options left over please let me know.
I will trow this well developed board out of the window and never look at it again.

[dc42]

The LEDs suggest that your driver module is receiving the signals from the Duet. Are you certain that you have connected the stepper motor correctly, and set an appropriate microstepping and motor current on the switches? Does the motor spindle lock when the ENA voltage changes from negative to positive?

You can increase the drive voltage to 5V by connecting +ENA, +PUL and +DIR to +5V (which is available on the servo connector of the breakout board) instead of to the individual + outputs; but I really don't think that drive voltage is the problem.

@dc42
The TB6600 stepper driver seems to be not a suitable driver for the duet.
This week arrived the DM556 drivers and they work without any problems.

Thanks for all the help!

Kind regards,
Leon.

To complete this thread for others. I had to use the 5v connection from the breakout board to make the DM556 to work properly. For some reason the 3.3v voltage from the +signals ENA PUL and DIR does not do the job for this driver.

[dc42]

Thanks for the info. We will feed this input into planned design changes, and consider getting a TB6600-based driver to test.
