Homing Z not working

1

Hi i’m new to the Shapeoko pro and having problems with Z. I know there’s a ton of stuff out there regarding this topic but unfortunately it hasn’t helped. I will outline my process and hopefully you can figure out what I’m doing wrong.

OK we’ll get started with Carbide Create Pro Settings for thickness, Z=9.525 mm. I will attach the file.

And now for the Shapeoko Pro.

I parked the machine turned it off/on. Loaded carbine motion connected to cutter.

At this point

Position

X =380.175

Y = 383.825

Z = -15. 410

Machine

X = 0

Y = 0

Z = 0

Load new file

Program size

X = 90.00 mm

Y = 163.00 mm

Z = 11.51 mm

Cutting depth below program zero -8.51MM

Initialize

Quick action to move cutter above current XY Z

Position.

X = 0

Y = 0

Z = 56.870

Machine.

X = -380.175

Y = -383.825

Z = -3.000

Jog

Position Z above Stock

Zero Z

Position.

X = 0

Y = 0

Z = 0

Machine.

X = -380.175

Y = -383.825

Z = -59.125

Run start job

X Y & Z same as above

Job just runs and never cuts into what wood.

That description of your process seems correct, and matches your file.

Which version of Carbide Motion are you running?

Could you post a photo showing your machine at the origin point relative to the stock?

Screengrab showing what the various G-code previews look like?

I’m on build 764 of carbine create and motion 622. I have atttached Gcode output from carbide create and a photo of the position of Z prior to cutting.
Thanks for the help

Could you have configured for an HDZ when you have a Z-Plus?

5

I don’t believe, so is there a way I can look at the configuration?

Check the Debug settings, or reconfigure per:

Below is the machine configuration from the debug settings screen. Thanks John

Okay, that was a dry well — the 200 for $102 indicates a Z-Plus.

Is there a reason you aren’t using “Carbide 3D Shapeoko” as your post-processor?

Post your .c2d file?

9

You should have it. It was on the initial post. I don’t have access to my machine at this time so if you want me to resend it, I will when I return. Thanks again.

10

Just thought of another thing can you run it using my .c2d file if it works we know it’s not carbide create.

Per your request I attached the c2d file. I decided to try using Contour Toolpath instead of 3D. What I noticed is that use stock bottom is defaulting to 19.050mm and takes 9 minutes to run. When I click on use stock bottom it defaults to 9.525mm what it should be defaulting to and takes 17 minutes to run. So, if I don’t over the default it runs at the 19.050mm. My guess is that 3D is looking at the wrong stock size and is cutting air. What are your thoughts?
