Your wiring looks right... I am just not sure about the Enable pins in the picture. My feeling is that they need to be connected to the EN pin on the header and also connected to GND.

I can see your problem.

Your green x wire should connect to the PUL+ on the Gecko.

EN+ on the Gecko should then be connected to the EN on the RPI CNC board.

Before you connect the EN+ cable you will check how the Gecko enable pins work. Do they need an 5V to activate or do they need grounding?

Thanks berthus,

After many tests, we found the good direction ;) .

I test with the micro stepper chinese cw5045 and tb 6560. All work fine.
I waiting my gecko stepper but think is the same wire.

Hi Jules and Bertus :)

I have been trying to hook up a HY-DIV268N-5A (TB6600 design) to the 2.51 Pi CNC board.
Tried a lot of alternatives with no luck, the Arduino resonds with a little flashing LED on my jog commands, according to the positioning in BCNC.
With the setup on the attached diagram, I get a weak light flash(about half bright) on the external drivers RUN LED on the jog commands, but no action on the motor.
Checked out a lot of samples online of people using this driver with Arduino, even without the Enable connections attached, even a guy running the setup directly of the GPIOS of the Pi....
See link: http://www.nlogn.com/blog/

Any suggestions and ideas to figure out this ?

Your wiring seems right.... :|

I have a bunch of these drivers on order and will try them as soon as they arrive.

My first DIV268N just called in sick !
Replaced the driver into my CNC plasma cutter running Mach3, same symptoms as with the Pi tests.
Tried another drive from ( I think the same batch), and ....... clockwork !
So my record in non failure cheep HY drives just took a fall, though I might suspect that it could have been damaged during hook up testing.
These drives have been working fine for me, used them by conventional BOB`s and never had any problems.
First time I`m using one against Arduino GPIO`s, but sure that it will be OK after this. The HY-DIV268N drives are cheep, but I always mount in fan ventilated cases, and the drives are never running continuously 5A in my machines.
BUT be aware ! the manufacturer documentation is at the time none existing. For drives that normally works out, but try to operate and program the jog and recording bios in the LCD screen BOB`s from the same not web listed manufacturer without documentation........ forget it and walk away :)

Good luck with your incoming drives Bert, and thanks for the psychological support :)

Viking greetings from Jan
