Z axis jogs in the right direction, but candles doesn’t show depth & Z axis in visualizer points wrong direction. everything worked fine until I got a new control board. Please help
What machine are you using that controller with? And especially, what are the specs of your stepper motors? That is not a very good controller for a cnc machine - recommended maximum current 1.5 amps/motor. You would probably be much better getting the Openbuilds blackbox (just to be clear - I am an unpaid, volunteer moderator here - I get no benefits from recommending Openbuilds stuff, so that is unbiased advice) - and get a decent power supply to go with it.

You can approach the vendor you purchased from for tech support for the product they sell If that doesn't work out: get a BlackBox (see docs.openbuilds.com/blackbox)
