I'm not sure, but there appears to be a few bugs in MSM or R3.043.012 of Mach3. I am running Mach3 with the Galil plug-in,
1. If I enter any command in the MDI window, it does a cycle start. This is very scary if a program is loaded. The program starts and the machine takes off. I installed a clean version of MSM and R3.043.012 on another computer and it also flashes the cycle start button when a command is entered in MDI.
2. After finding this, I made sure there was no program loaded and entered the spindle command string M3 S1500 in MDI. This will start the spindle at the correct speed and direction, but the spindle stops after about one second. I can manually start the spindle with the CW or CCW buttons.
3. When I run an edge finder to verify my vice location at offset G54, Mach3 forgets its absolute position, the softlimits are no longer accurate, and it is easy to run the machine into a limit switch.
4. One really weird problem is if I run the NewFangled linear hole pattern wizard: the X, Y, incremental, and angle input windows display unstable numbers. I believe the other wizards function normally.
I did not find any of these problems with the standard Mach3 R3.042.40.
Having said all the above, I think the MSM screen set is very nice and I like its logical set-up.
One request is to add a NewFangled Wizard button to the load screen. I miss that one.
Thanks,
Jim
