G'day All,
I've recently rebuilt my CNC lathe and is exhibiting some strange behaviour. I'm using the mach motion canned cycles (I've used them before, they all work [except threading, but thats a different problem], and there have been no software updates or changes since the rebuild).
The code generates is accepted and the tool path is displayed. On pressing cycle start it prompts me for a tool change, starts the spindle, rapids over to the start point and then.... stops. The spindle keeps running, there are no error messages, it just sits there. Literally doing nothing.
The first ~20 lines of code are here, it all looks good to me:

N95 G01 Z-0.3000 F0.1000 (Cut in on Z-Axis) <----- it stops on this line here. it recognises the distance to go but doesn't move
N100 G01 X-0.5000 F0.1000 (Cut in on X-Axis)
N105 G01 X-0.5000 Z0.0000 F0.1000 (Spring Pass)
N110 G00 X-0.3000 Z0.1000 (Pull out to Retreat)
N115 G00 X18.7000 (Pull out to Clearance)
I've attached a screenshot (literally a photo of my screen as I didn't want to give the computer reason to do anything stupid by opening the snipping tool while it was all enabled and working). The only difference is I tried running it again so it didn't pause for the tool change because the tool was already loaded.
Your help would be greatly appreciated. I want to make these parts...
