Hello, I am pretty sure this is a software problem because my Shapeoko XL performs fine with other pieces of code.
I am using Carbide Create, Save the G-Code, and jog over to the spot and bring the bit down then zero all, then execute the G Code. It retracts then the plunges very slowly and never reaches the wood before it starts moving in X-Y directions.
Settings, ]304.8mm 304.8mm, 6mm thickness, Retract 7mm
Cut in question: 2.470 step, 1.3mm depth pr pass, 680 feedrate, 85mm plunge, 5000rpm. 5.5 mm endmill
Pocket: Start 0, depth 3.75mm`
Where is the origin in Job Setup | Stock thickness | Z set to? Is it set to Bottom and you are setting zero on the surface of the stock?
You do not mention if you are using a probe to set your zeros. Set your spindle in the middle of your work piece and go to rapid position, press Zero +6 button. The bit should move to 6mm above your workpiece. Set your movement to 1mm and press 6 times on the Z-. You should be right on your workpiece. If this is not the case, it is your Z zero that is not set properly.
Doh! Stock bottom was set. I usually don’t mess with that but must have flipped it to the wrong one accidently.
