Not sure if I wired my limit switches correctly. I attached an image to look at but not sure if it posted.

Hi Glen,

It's OK them being in series like that, but you didn't mention where are you wiring them to. Is it directly to the PP without a breakout board? If so then I think that the PP inputs are being pulled down normally anyway, so you'll need to connect the other side to 5VDC instead of the COM (which I assume is GND in your schematic)

Dan,
All I have is the the power supply hooked to a 4 axis driver board model (TB6560HQT4-V3) purchased from Ebay. What does PP stand for and do I need a breakout board. I can jog my motors but after I wired the limit switches they stopped working. Once I disconnected the limit switch I could again jog the motors. This prompted me to ask this question. I have another block of connectors labled; 5v (output), PU/CK (pulse), CW (direction) EN (enable) and GND (ground). Should I still connect to the 5v or GND?

Thanks so much!

Can you attach the driver manual or a link to one?

They don't exactly provide this information in the manual, but based on their Active Low setting in Ports and Pins for the limits (on page 20) I think that the inputs are normally pulled high. Changing it to Active High (uncheck the Active Low box) should fix this.

I unchecked the active low box and still can't jog the motors. I checked all the switches and they are closed. Hummmm...

Go the the diagnostics page and see if the limits LEDs change state when you play with a switch.

On the Diagnostics only the M4++Limit LED is yellow. When I trigger any of the switches it turns off and nothing else is on. See attached pic.
