Hello,
I have purchased a super long board to control a Vision 1624 router with no included controller that I came across. The Y and Z axis seem to use nema 23 motors and the X axis uses a smallish nema 34 motor. I installed the super long board and am having luck with the nema 23 motors but the nema 34 is struggling. I would like to maybe throw in a larger stepper driver just for the X axis. Is it possible to tap the step and direction TTL signals on the board somewhere and use them to control that driver while keeping the Y and Z axis connected directly to the SLB? I am using Gsender and have to say… I LOVE IT! Do you guys plan on maybe making just a SLB without drivers and just control outputs any time? Thanks in advance for any advice.

Hey Jim,
There are schematics available to get into depth on where to find direct io points comming form the up. The one for the x driver looks like this:
Found here:
I however have my doubts you need to. You say it’s a smallerish stepper than the nema23 ones so the slb should not have a problem driving it.
Have you exhousted every other possible option to troubleshoot the x axis?
Have you tried the calibration tool. Played with steps /mm settings etc?
Maybe something is wrong mechanicaly, even?
I feel a secondairy driver will not do much besides void your waranty on the slb.

Howdy, thanks for the reply. The X motor is a smallish Nema 34, not 23. The other two (z and y) are both nema 23s.
Do you think the step and direction signals are available on the big rectangular connector (kinda looks like a dual row maybe 40 pin connector)?
Exact, the x motor is the smaller one, the slb shouldn’t nave much problems with.
But allaz, it never hurts to look.
The GPIO (P11) does not seem to include the stepper signals besides the A axis.
@jimbomatic not sure where you ended up going with this, but we do have an alternate version of the SLB we’ve been trying to make available for a while now for this very purpose (no on-board drivers, just pinouts for step/dir), but since you don’t have that it your hands right now the best I can say is:
- breaking out the step/dir on the SLB is likely not going to be an easy feat since if it was we would’ve done it - unfortunately we just couldn’t justify the extra work so that’s why the signals weren’t made available on the board
- the SLB always has the A-axis motor output - so another option is you could use that to drive a stronger external stepper motor driver, then just alter your CAM post processor to send X-axis signals as A-axis signals and that might work too though it would mess with the visualizer and jogging in gSender a bit
