Centroid Community CNC Support Forum

Thanks Centroid_Tech2, why is it different? I'm just wondering, it will make no difference to the functionality, but I wouldn't mind knowing why we need to connect the negative side of step and direction using the screw terminals and the positive side of the same using the DB25?

Next, I will return to my original setup, using the screw terminals on the Acorn board and see if I can get the motor turning using that interface.

For posterity, CNC12 error 9031 Drive Fault was caused by the "Drive OK" input being set to normally open. I changed the setting to normally closed in the Acorn Wizard and removed the error.

I should mention that the actual error from CNC12 is 9031 Drive Fault.

I connected the cable that I produced from Centroid_Tech2s diagram and the drive now rotates. It only turns about 1/4 of a turn in either direction, before CNC12 stops with a drive fault error.
Progress indeed!

Here is my reading of the connections provided by Centroid_Tech2. I still don't know whether the cable works, but will soon.

I made a cable based on the diagram you provided Centroid_Tech2, using the Acorn board's DB25 connector and the DB44 connector on the DA98B. I haven't tried it yet, but I will post the result and the document that I created showing where I connected things, based on my interpretation of your diagram...

Here is a screenshot of the DB44connector from the DA98B manual. It shows which signals are inputs and which are outputs. The table wouldn't copy entirely, but the pins in the left hand column are inputs, the center column are outputs and the right hand column is labelled as "other". DA98B...

Sadly both PA04 and PA14 were already set to a value of zero. I removed all of the wires that I had installed and reinstalled them as per your diagram, which happened to be the same as my original wiring. I checked with a DMM that there was continuity on all the connections that I made (I had done t...

For my reasoning behind this see pages 29, 51 of the DA98B manual that I posted earlier in this thread,
