Bounds Check, Machine not working

Software Carbide Motion
1

I am brand new at using CNC. I just got the Shapeoko 5 pro 4x2. I am trying to run a test cut and I keep getting this message.

Project will hit right side of the machine (X+)
(The program zero is 105.1 mm too far right)

Project will hit the back of machine (Y+)
(The program zero is 98.7 mm too far back)

Project will retract above the top of machine (Z+)
(The program zero is 13.7 mm to high)

I have run the setup, and the position is set to Zero on all perimeters at the back right position. Thanks for any advice

This is a warning as noted at:

https://carbide3d.com/blog/carbide-motion-bounds-checking/

Usually it is caused by a mismatch between job setup:

https://carbide3d.com/hub/courses/create/job-setup/

and how origin is set relative to the stock:

https://carbide3d.com/hub/courses/running-shapeoko/movements-zeroing/

I find that opening the .c2d file up and drawing a box which matches the specified dimensions (draw up the cut in profile if need be) or moving the machine to the origin and then using a tape measure to measure out the dimension(s) in question will make clear where things arenā€™t lining up.

As far as I can tell, my dimensions are correct, and I have the stock in the front left position and that is what I chose in the setup.

This is all brand new for me.

You need to set Zeros to match the workpiece you are trying to create. Are you using Carbide Create? If so, the ā€˜Job Setupā€™ tab will tell you where your Zeros have to be in relation to your workpiece.

Then this determines where you should set the zeros on the machine to match the zeros in the design:

So in this particular case, you would move your spindle until it was over the lower left corner of the workpiece, and zero out X and Y, then jog your bit down to just touching the top of the workpiece, and zero out Z. You can also use the BitZero (if you have one) to help set these values.

Now your machine and the design program agree about where the Zero point of the program should be, in relation to the workpiece.

You would almost never use a Zero located in the back right corner, this corresponds to what is called the machine co-ordinates. These are typically only used to move the spindle to a particular place over the bed, perhaps to match a jig or fixture that you place there.

I will give that a try, thanks for the input. Much appreciated

Set all axis to zero in the lower left corner of my stock, I tried to run program, and the machine went to zero at back right of machine and lowered cutter down. I had to stop it manually.

Any suggestions ? Thanks

Do you have a BitSetter? If not, is BitSetter enabled?

If you do, is the BitSetter correctly configured per:

https://carbide3d.com/hub/docs/shapeoko-setup/

If thatā€™s not it, upload your .c2d file, post a photo showing the machine at the origin (or a specified offset from that position), and screengrabs showing Position, then click on ā€œPositionā€ to toggle to ā€œMachine Positionā€ and post a screengrab of that as well.

I had a similar issue today (the out of bounds on XXXL were smaller than listed here, but I do not remember them at the moment. I did not have this issue on previous versions of motion (that I had over a year ago - new computer and machine was in storage so versions are fresh installs) I also do not have a bit setter. Any other specs/settings to check?

Basically this is an interaction between:

  • the length of the current tool
  • where the zero is currently set on the machine
  • the extents of the file

If you have a problem with this we need:

  • a photo of your machine showing the tool at the zero position or a specified offset
  • screengrabs showing ā€œPosition/Machine Positionā€ when at zero
  • the file
