I am writing as a hail Mary pass. I am running a program for my grandson’s birthday present.
I have a Shapeoko 4. I setup everything ok except after I zeroed it (I think I zeroed it anyway), I raised the router to attach the vacuum assembly. I lowered it back down and didn’t pay a whole lot of attention, thinking it knew where it was at.
I started running the job and realized that the Z it actually at negative 1.145mm (which is odd because that happens to be the amount per pass the bit takes off per pass. It’s taken about 5 hours to run the program. Just a few minutes more but I don’t know if there is any way to find out it’s initial starting coordinates. I just used my little probe and put it about an inch from the edge of the board. (The board is longer than the project so I didn’t place the probe on an actual corner.)
Is there some feature which you can use to verify the position?
Note that the origin should be persistent/retained, so as long as you don’t change things it should still be set to where it was when running that file.
If so, I would open the NC file in NCViewer and look for that feature.
You can select points on the path.
The code window will scroll to there and the coordinate display will show where you are.
Thank you for your reply. I really appreciate your input. I replied to Will just a few minutes to give an update about where things sit. I hope there is some resolution. That piece took forever to cut yesterday!
When you raised the Z did it hit the physical limit? This will cause lost steps and your toolpath to carve deeper than planned.
Always a good idea to double check the Z height before hitting “Start”
