TB6600 configuration issue servos won't move

Hello,

I have purchased a 3 axis TB6600 control board off ebay for a project i am working on but unfortunately i am struggling to get anything to move.

I have configured the pins as described in the following datasheet but whenever i run the axis test all that happens is relay 2 fires for a fraction of a second.

This suggests to me that the pulse signal is being sent to the relay channel. So i tried swapping the dir and step around and the relay fires and stays on. However, this happens when i test all tree axis.

I noticed in the datasheet pin 14 is listed as enable all so i searched the web and found the following solution:

forum.linuxcnc.org/27-driver-boards/2687...ble-axis-in-linuxcnc

which adds 3 lines to the custon.hal file but still doesn't work.

Can anyone tell me what i am doing wrong?

thanks

Jason

Welcome. It's always a good idea to post the hal and ini files from the config folder when looking for help.

Clive,

Thanks fro a quick response. Please find attached the files requested.

thanks

Jason

not sure why all the files didn't attach to previous post

I thought the tb6600 was a stepper driver?

Hi sorry I meant steppers.

Maybe try to tie machine.on to enable?

Not sure if I am on the correct track here but: In the hal file

setp stepgen.0.steplen 1 try 5000
setp stepgen.0.stepspace 0 try 5000

Are you getting any error messages?

He is using double step mode so 1 and 0 are correct, the "setp parport.0.reset-time 5000" line takes care of the timing.
