Please excuse me, as the first post was done in a hurry and it does not make sense... so here goes again:
Hello guys
Is there someone who has successfully connected a torch height controller (THC) with the NVUM v2 controller?
I was looking at the Proma SD model and it seems that the Proma works with a positive Step and Dir signals, where as the NVUM works with negative Step and Dir?
Please see the attached image where I marked A and B. Does it rely matter what polarity is the Proma SD is switching for the STEP and DIR?
Maybe I think the wiring schematic they provide is generic, hence showing positive STEP and DIR inputs is not to be taken as literally??
Can some one help please?
Thanks
