I upgraded Vcarve desktop 11.5 to 12.005 then the SLB arrived and I upgraded gsender to 1.4.6. Now projects designed in Vcarve 11.5 are out of alignment on the Y-axis sometimes in + direction and sometimes in a - direction. Once both Y-axis motors seemed to stall on the way to the carve starting point and another time only the right motor stalled. These were projects designed using Vcarve 11.5. Since then I have designed 3 different simple projects using Vcarve 12 and their carvings were positioned perfectly in relation to the point of origin. Does this mean I can’t carve any my old designs or is there something else going on?
