Hi, I'm new to the Ox but I have got it to work. However when I do more complicated projects the machine appears to skip steps. For example, when I was cutting a matrix of dimples (concave shapes), it was working and then all of a sudden the machine started cutting them much deeper than programmed! I have had similar problems in the Y direction too. I'm using VCarve Aspire to design the pieces and produce the Gcode. Could the file format (Gcode) be at fault? I have tried running the machine with a slow feed rate of 200mm/min but the problem is still there. Any ideas as to the cause of the problem and possible solutions would be greatly appreciated.
