Weird external driver issues

Post by X35 Design » Mon Jun 04, 2018 3:16 am

I bought 3 tb6560 drivers to use with my CNC hat. I have them wired correctly as far as I know, but they will not move the steppers. If I jog in one direction, it just hums/whines, and if I jog in the other direction, it just makes one 'clunk' and does nothing more.

Here is a quick video I made:

re external drivers:
I've just followed the wiring back with the thought that I could take the step and direction direct from the board it turns out the the output screw terminals are (reading left to right, with the terminals are the bottom of the board, screws up) direction, step, enable, ground. I had them wired Ground, enable, step, direction. I had the same problems as you, now my drivers seem to work (Wantai DQ542) the previous TB6600s still dont work though!

So you're saying that the Protoneer 2.6 board if I'm looking at the top, (where the writing is)

it goes Dir/step/enable/ground for each the terminal block when I'm using the external driver adapters?

See ascii art:

|--------------------------------------|
|--Protoneer 2.60 |
|--------------------------------------|
|ground ground ground ground |
|enable enable enable enable |
|step step step step |
|blank blank blank blank |
|dseg dseg dseg dseg |
|--------------------------------------|

Is that how it should be wired?

Yes, suprised me, please feel free to check I would like a second opinion. But my meter says that with the red external driver board in place the left hand screw terminal is connected directly to the solder-in hole marked dir., just above the pinouts for the onboard drivers, as is the step, enable and ground respectively. The 542 external drivers connected this way round now work correctly.
