Linear move on axis Y would exceed positive limit... was created by vmihalca
Hi guys,
I had this issue before with Z axis but it was a different issue then.
Here is what happens now:
The home of the Y axis is in the midle of the Y travel, and min=-117, max=117
There are a few things I don’t understand.
Why the Z azis goes past of the Z0 of G54?
Why the commnand at line 26 can be executed successfully in MDI?
I ran this code before, I’ve made a part with it.
Since then I’ve added 4th axis so I had to set the center of rotation.
Here are my config files:

Having the X and Z machine zero on the rotary axis isn't actually any help with anything, as it happens.
It might give clearer graphical previews, but I have a feeling that even then the work coordinate origin rather than machine coordinate origin is used.
G-code is basically axis-of-rotation agnostic.
That said, there shouldn't be a problem with your current setup.
If you view the preview from the top, are all the lines inside the bounding box? "Line 26" might be out by a few, I think it ignores blanks and comments when counting.

Hello. I guess you set the length of the z axis too small.
[AXIS_Z]
MIN_LIMIT = -120.0 //Try to make this bigger.
MAX_LIMIT = 240.0 //Try to make this bigger.
MAX_VELOCITY = 50.0
MAX_ACCELERATION = 500.0Please Log in or Create an account to join the conversation.
