@Nightowl thank you for the reply.

What I want todo is basically set a macro that will take the bit over to the tool length probe location and measure the tool length and set the offset so that Z0 is the top of the spoilboard.
Currently when I probe using the tool length probe it sets an offset between the current Z and the probed.
I am not sure how or where to tell it how far the probe switch is from the top of the spoilboard and I think that’s my issue.
The job setup and stock settings are fine.

@Nightowl thanks for the reply.

I am using a Duet3 Mini+ with version 3.4.5 in SBC mode.

When I run job with the RepRap post in Fusion 360 jobs work okay but I am trying to understand what is happening in Carbide Create 6.52 that is causing the cuts into the material.

So here’s a question maybe somebody’s already done this. I have a tool length switch or probe setup on my waste board.
Right now I use an aluminum touch block to touch off the material and then send the job.
Could I and what might the macro look like if instead I setup my job with Z 0 being the spoilboard and instead of using the aluminum probe the machine just goes over to the switch checks the tool length and sets the Z height.
I am sure it’s possible just just not so sure how to set that up in firmware.

Hey Guys,

I have a questions about Carbide Create and I can figure it out.
I have a file that has 4 tool paths in it but uses the same bit. I load the file and edit it to remove the M0 at the start and then run the file.
When it moves from one tool path to another it lifts the bit clear of the material but then puts it back down and moves to the next tool through the material and I just cant figure out why.
I am using the GRBL post processor but have tried Marlin as well with the same result.

@baird1fa said in help with z touch off macro:

G38.2

Do you mind sharing what your final config or setup for this was?

@jay_s_uk thank you. Sorry given the title was using Lightburn over USB I thought maybe you had a way to make that happen. Doing it all offline or not live in the software is okay but there are tools in the live software that would be handy for sure.

@OwenD thanks man. Appreciate the help.
Apparently it was user error. I was messing around with building a tool probe and it was set wrong causing the Z axis to see the probe as tripped and wouldn’t home.

@OwenD okay thank you I will remove that.

However if I put this into the console nothing happens with the Z axis:

G1 H1 Z{move.axes[2].max*2} F900

It should shouldnt it?

So I have a strange problem where my X and Y axis will home just fine and my Z will move and I can probe and everything but when I try to home it using the Home Z button it does not move at all.

Any help on what I did wrong as I am sure its pretty easy fix and just something I overlooked.
