I got the Fystec PITB with the 2 BIG 5160s can board, got it working on can and everything works, fans rgb leds and whatnot but get this eror message when trying to move the x or y (what im using them on) steppers, googling has been of no help. im still trying to rap my head around the spi/ ic2 bus and how it works, but has anyone else ran into this issue?

You have to power 48V as well. Just jump 24V to both 48V and 24V rails.

thank you! i thought i had updated this post i found this same coment somewhere like 20 mins after posting this orginaly. If i may ask where did you find this out? cause there documentation is garbage

By fucking around with wires until it started working. At least now I can use thick 48V wires to transfer power to extruder CAN Board rather than thin 24 V wires...
