hey gurus, I've got a maker store outback 1500X1500 with a fohlin VFD & 2.2KW water-cooled spindle. I had an issue arise yesterday out of nowhere. machine was fine and working Monday. Yesterday (Wednesday) I set up a 5mm drill bit in the collet and zeroed the machine and pressed go, luckily I only had a 1.5mm peck depth set as on the 3rd hole I realised something wasn't right and upon stopping the machine realised the spindle was going backwards, weird never had this happen before and to be honest didn't know it was possible, maker store wants pics/phots of it setup although I know it worked fine, something weird has happened and it has me stumped, I don't wish to reverse the wiring and make it an easy fix as there has to be a reason it has changed. has me perplexed
