Dear hood, i am newbie in cnc. My new bought cnc jog key can move fine in step mode, but not in Jog continue mode. When i click Jog continue for any axis motor just turn a bit. If i keep press hold the Jog key, still same move once only. Look like inching movement, when i do it offline the mach3 run well with continue increase the position. This was happen in ref all home too, only Z axis move a bit then hang up there, need to press Emergency stop to reset. Hope to get the mach prof. advice..... Thank you.
