Welcome to the SeeMeCNC Community

I got a 4 Axis Board - TB6560 from SeeMeCNC store. Does this version require the opto coupler fix? Can some one please provide some info?

Thanks,
Jacob

Never mind, I found the post. http://forum.seemecnc.com/viewtopic.php?f=22&t=49

niner, some people don't have any problems with the optos, but some do? If in doubt, jumper them out. haha. I think it has to do with P port voltage, some ports are 3v and some 5v, i'd guess the 5v ones don't have any issues pushing thru the optos

Removed the optos as described in this forum and rewired with reformed staple pins. Time to spin the motors
