Mach3 board to T41U5XBB grblhal - servo drive connection

[Switch-Witch]

O


n the way to replace my mach3 board with a T41U5XBB. On the mach3 board my servo drives were connected with dir- pulse- and a paired pulse/dir +. On the T41U5XBB the board offers one ground and dedicated + for pulse and dir. I tried to modify my cables that way but the servo drives are not getting a useable signal. When using the modified cables on a stepper driver it works without any problem.
What to do to fix that problem?

What to do to fix that problem?

Either connect DIR+ and PUL+ to 5V or DIR- and PUL- to Gnd and DIR+ to Dir and PUL+ to Stp. Depending on your choice you may have to invert the step pulse ($2) and direction ($3) signals.

Thx a lot for your help.
The solution was the much higher resolution awaited from the servo encoder than a regular stepper motor.
Now they are moving - what to do to fine tune will be the next challenge 😄

Thank you
