When I run an example gcode demo (i.e roadrunner), the gcode display cycles quickly thru the 1st four lines and hangs at line 5 (G43H5). For the next 20 seconds or so, there is no visible activity. After that, the next to last line of gcode (M5) highlights. It's as though the code may have been executing without the control panel updating.
In single Block mode, I am able to step thru the program, but all of the Axis (X,Y,Z and 4) display remain as +0.0000.
I have installed Mach3 Demo Version R3.043.066 on two different Windows 7 machines and it behaves the same on both. One is 64 bit and the other is a 32 bitter.
It must be a cockpit error, but it's got me stumped. I have a Haas TM1 in my shop and run it regularly, so am very familiar with commercial CNC machines.
Where might I be going astray ?
Thanks
