Hi Bob,
Had a look at your Gcode file and made some changes I wasn't sure if you were imperial or metric but guess imperial.
The G50 is not supported but you can use S to set the speed.
I put the G90 at the beginning of the file for convenience but that's just me.
It is best to use 1 line per gcode instruction as sometimes the 2nd gcode may be ignored or maybe the entire line.
I added a G0 to the Z.25 but I just like to be tidy and Masso will remember the previous modal Gcode.
When it came to G1 Z-.7 F.01 you had the axis did not step over it as you experienced, but embarked on an agonizing 95 minute move at 0.01" per minute. I changed the feedrate to F0.9 for my test file so that it would finish the move in my lifetime ;-)
Total machine time for the Gcode below 1:07 minutes with the G1 taking the 95% of the time to complete it's move.
G20
G90
T2 M6
S1750
G0 X-8.9595
G0 Z.25
G1 Z-.7 F0.9
G0 Z2.
M1
M30
I have uploaded the file for you to try and see if it runs for you as it did on mine. If it doesn't you may have some setting wrong in your setup.
You may need to upload your settings file.
I tested this using Lathe Version 3.46 and I am assuming you have a Masso G3.
Hope this helps
Cheers
Peter
