For setting up Halo in MACH3 and CNCpro, here are screen dumps of a MACH3 software setup and CNCpro softare setup. Each user will typically have different setups for motor tuning, as the acceleration and velocity settings depend on power supply, mechanical efficiency and load, step to unit ratio (steps per inch) and motors. Here is a .ini setup file for Turbocnc. turbocnc.ini Here is a MACH3 setup file mach3mill.xmlthat you can unzip and locate per MACH3 instructions. Sepconf for EMC [Halo Stepconf File]
Here is the Halo board insturction manual (work in progress).
Halo comes with a 6" cable to a DB25 for easy panel mounting. It also comes with a heat-sink and fan, and is preset to the current setting for the users motor and step settings. The price is $149 plus $8 shipping in the USA.
