Hi guys
No macropumps or brains. The only other plugins were video window and turn diagnostics which I have removed from the plugins folder. I have started a new profile from scratch but problem remained. I have also swapped out the computer with a spare, No change.
However I have moved forward with this. Firstly I discovered that M3, M4, M5 ans S word worked normally from the MDI input, it was only G code that wouldn't work. I changed the keyboard from a USB type to a PS2 but problem remained.
Then I discovered that if I had a G code program loaded, the MDI input would work in all respects. But I could not load a G code program after I had tried to input an MDI G code because I would get an alert every time I tried (See atachment).
To explain better, there are 2 scenarios:
1. Start up smooth stepper, try to input G0z20 into MDI, nothing happens, system is locked up. Press Estop and Reset, system is working normally except for MDI input. Try to load a part program, get SS alert as attachment.
2. Start up smooth stepper, load part program (any of several), everything is working normally including the MDI, no alerts.
This has solved my problem really, I don't understand why it is the case and whether it is just the way it works or if it is specific to my setup.
Anyway, thanks for your help and I will be running with SS from now, if there are any further developments, I will keep you posted.
