Very bad issue with a .nc file
« on: October 04, 2010, 12:46:05 PM »
Hello,
I just had a crash in my machine, when I loaded and ran the file attached.
When I load the file, I get a "out of limits" warning. Which definitely can't be the case, because the files limits are at about 1700mm. I set machine limits to +/-3000mm.
What happens is: The first axis command is a Z1.5, to lift the tool above the detail. Now Z does not lift 1.5mm, but ... I don't know how far (some cm at least) because I have to emergency stop it.
The z-gauge on the screen is counting correctly, but the axis is getting way more pulses, like if the steps/unit value would have been changed by factor 10. Checked this one: It is still set to the old value.
If I use a different file with a smaller part which is identical up to the point where the Z1.5 command appears: No issue.
If I run the (bad) file in CNC Simulator: No issue.

I am using R3.042.029 and I am not sure whether an update helps.
Anyone an idea except "try it out" :-))

Thank for helping out

Your code has a G20 at the start which means its in inches, so when it asks for a 1.5 move that is 1.5 inches and not mm, ie 25.4 times bigger.
