I doubt not having a home switch is the problem. I run a CNC'd mill-drill with Mach2 / Geckos with no home switches and never have problems with crashing on any of the axes. I would recommend double checking your programs for moves that would create the crash. What kind of computer are you running Mach3 on? Perhaps your computer is not fast enough, and is losing steps?? I did have this problem with my machine, and it took a faster computer to solve my lost Z-axis issue. If you are sure the computer is plenty fast, I would start looking for slippage in the mechanical system or noise problems (probably in that order). Hope this helps!! |
