Odd Y axis problem with G540
Well, I finally got my X2 mini mill CNC'd with the CNCFusion kit. Running Mach3 last week. I configured Mach and had the mill working flawlessly. I only made test runs with a pencil chucked in the mill but have drawn dozens of figures, text, etc all with no problems.
So, for my first actual cut, I wanted to cut the steel front panel on my electronics enclosure to fit the G540. I drew the shape in CamBam and generated the Gcode, transferred to Mach and test ran (with pencil). All was fine. Then when I was preparing to make the actual cut, I decided to do one more test and this time my Y axis did not move. The X axis moved fine. I started debugging. The Y works flawlessly when using the keyboard or jog panel jogs. When I enter Gcode in Mach's MDI panel (I think that's what the 2nd tab from the left is called) I can perform a G0 Y'n' moves 100% of the time. However, the G1 Y'n' moves are the ones that failed running my CamBam output and they also frequently fail running from the command line. The Mach display shows the movement but the motor does not run. I switched my X and Y motor leads and tested and again, it is the Y port on the G540 that intermittently does not respond to G1 Y commands.
I am left scratching my head. If it is an electronics problem with the Gecko, why does a G0 Y'n' always work and a G1 Y'n' sometimes not work? I do not know how these translate to control signals to the G540.
Any suggestions, ideas, or help GREATLY appreciated.
cheers,
