Hi Tony,
Just from memory, the main change between the first version of Mach4 and Mach4 v.2 was a major update to the Lua version. This prevented the v.1 Lua scripts / macro's working correctly with v.2 so they had to be re-written.

I’d check the Mach3 spindle output and XHC plugin port/pin assignments first, because an incorrect spindle-enable or direction signal can cause the VFD to run immediately while leaving M5 ineffective.

Hello, I’m having a problem with thread cutting in Mach3. The cutting tool stays on track for the first 2–3 passes, but then it drifts off, ruining the thread. I’ve read that thread cutting only works with a specific version of Mach3. Does anyone have experience with this or know which version it is? Thanks, Hans

Hello, in the Mach3 > Settings > Ports and Pins > MPG Settings its possible to activate Encoders and MPGs. What is the diffrence between using teh Encoders and MPGs. Its necessary to connect Axis to encoders or mpgs? Thanks Hans
