I am in need of starting to cut STL files and need more than CC can give me. I am attempting to use Kiri:Moto online to create my Gcode to cut files. The issue I am having is that regardless of what I do, it is that motion is wanting to cut below zero.
When I run simulations, everything appears to be correct and withing bounds. Carbide Motion shows the values to be pretty correct in the Program Size summary. But the cutting depth is below zero. I am attempting to use the following for my XYZ Origin.
XY : Center of my stock
Z: Top of stock
I set the same in Kiri. When I get the summary, it shows it is cutting below zero. The program size appear to be correct and unsure why it is cutting so low. Attached is the Program Summary and a zip of the Kiri:Moto file and gcode generated the kmz file will load all my settings into Kiri:Moto @ Kiri:Moto . Any help would be appreciated.

This was after a couple tries. Left out roughing as I wanted to simplify the issue. I should have uploaded the version with roughing enabled. I did have it set to .1 inch for the rough pass on the original. Which I have attached to this post. I am trying to understand why it is attempting to go so far down below the stock when I run it in Motion. It looks good in the view but then it starts .5 inches below z. when it shows correct in the viewer.
I have attached my version with roughing with a Depth Per Pass of .1 before doing the contouring with a ball end. I have attached the files updated to show those.
That is what is confusing me. If you look at my Carbide Motion Program Info it shows it cutting .5 below program zero. I verified and reset my origins before loading the file to ensure everything was correct. My first cut I attempted the bit just dove into material and quickly paused the program and halted. I have not attempted another cut yet, because every program I pull up shows a cut below zero. So, I am assuming something is still wrong and didn’t want to risk a bit trying it.
Before you try to cut actual material, just practice with an air cut run. Set the machine Z-zero well above the bed or stock height(but at a known value for reference & high enough that the program depth won’t contact any material ) & run the program thru the air watching how it goes.
Oftentimes the machine Z-zero set point is not matched properly with the program Z-zero.
You were all right. I think I initially used a version without roughing and then made assumptions without testing. Verified all operations and tested again. Success. I think I got too used to CC and just kind of riding the feed rate sometime for speeding up the roughing process. This will help me be more deliberate in my machining operations. I appreciate everyone for helping point out my errors.
