Z axis cutting deeper than programmed!

[Metalmauler (William m taylor)]

I own a XXL PRO. My laptop crashed and it will be 3 weeks or more
before it is ready. That being said I purchased a new laptop and loaded the latest
versions of Create and Motion. The Z axis is cutting deeper than programmed. I have
tripled checked my program and checked Carbide Motion several times. My first cut
is .130 deep but it cuts about double that depth. The depth is set for .760 deep but by the time
it reaches .500 it has cut thru the project and into the spoil board. I think I loaded the correct
machine parameters. I am at a loss for solutions. Any ideas?
Thanks

Did you send the correct machine configuration?

Setting Grbl Configuration in CM 517 and later

Carbide Motion 517 uses a new system for setting Travel Dimensions which is potentially confusing: [image] Pressing the Load Defaults button takes one to a window which allows one to select first machine size: [image] and then Z-axis type: [image] after which selection the Travel Dimensions for the selections made are entered into the dialog and will be preserved if one clicks “Ok” (and of course that change discarded if one selects “Cancel”). In addition there is a “Send Configuration…

Sounds like you’ve configured for an HDZ but have a Z-Plus.

That could be the problem. I will give it a shot tomorrow. I have
operated cnc machines for years and I hate getting my butt cut!
Thanks for the prompt response.

I have exactly the same problem. I double checked that I have set and sent the correct machine information (Shapeoko Pro XXL with Z-Plus) but it always cuts 0.25 inches too deep no matter what I do. I clear offset, set zero all has no effect. Even if I put the zero position higher at 0.25 inches it still cuts too deep. I really don’t know what else to try.
