I brought in 2 Shapeoko for my high school.
I design various projects that are easy to complete.
We use a surfacing program to clear a cutting board.
Each student will surface one side, then the next till go.
When the 2nd student runs the program, inevitably the Z crashes.
We then have to re-boot, start over, initialize etc…
Any thoughts?
Can you be a little more specific? The Z Crashes… and also let’s talk about the Z0. Was it reset by the second student? Top/Bottom of the part? Witnessed and verified?

This is usually caused by a disconnect in how the zero was set relative to the stock:

and how the origin was set in the file:

If you could post:
- step-by-step instructions for how the first piece of stock was secured
- step-by-step instructions for how zero was set relative to the stock
- the .c2d file which was then run
and
- step-by-step instructions for how the second piece of stock was secured
- the second .c2d file which was then run
we should be able to work through this with you.
Yes, the PRZ, which is the part reference zero or position reference zero is where the project start starts.
That is X0Y0Z0.
We then start run the program and it moves through with starting position and generally runs OK. then, when the next student runs the same program, will reset the Z because each cutting board is slightly different and thickness so when he resets the Z run the program and it will then go to position to cut and slam into the board rather than a gradual, slow entry to clear the cutting board.
Unfortunately, what we found is we have to hit the red button re-initialize the machine go through the same steps to reload the program. Find our PRZ our part reference where we start the program from and then it will run OK.
However, this seems to be the wrong way to do things. We shouldn’t have to shut the machine down restart rehome the machine go to our PRC and have each student load the program go. We should be able just to start the program reset the Z forget about the Xand Y. We should then just be able to continue surfacing each of the cutting boards for each student. Very frustrating.
Thanks for all that info.
I’m confident in all that as I run Mastercam and Vectric aspire.
This is unusual.
It seems that it should be a no brainer.
Each student has the same size cutting board (within reason) and the only thing that changes is the thickness, hence the need to change the Z.
I built a jig to set the part in they then gave to lock it into position and cut.
I guess I’ll have to send a video.
Shapeoko 5 Pro.
Try running the gcode ( without a bit and no stock ) to it’s end.
Do some Z height change.
RELOAD the gcode file and run to it’s end.
Do some Z height change.
RERUN the gcode to it’s end.
Yup
Bit in or not, it’s the same process I’ve been using.
I wondering now if we have a Max Depth of .02 and if the depth per pass (by default) is deeper than the Max Depth, is that the issue?
But, it can’t be. We’re running the same program over and over.
It’s killing me time wise. 25 kids per class, one machine, simple 5 minute program.
It shouldn’t be happening like this.
I’ll rewrite the program in Aspire and see what happens.
Curious, what CAM program are you using?
We are using Carbide Create V6
What do you use?
Carbide Create v6 hasn’t been supported for a long while:
