Continuing the discussion from New HDZ on SO3 XXL Stops short on Left X-axis:
I’ve tried to figure out the Grbl configurator and that is well beyond my understanding. It was working perfectly before the HDZ upgrade. I cannot resurface my wasteboard and I’m losing workable space too. There has to be an easier way to change my travelx setting. The picture shows the max x travel to the left and clearly it was beyond that.
It should work to select the correct sort of machine and Z-axis and size in Carbide Motion.
It may further help to calibrate for belt stretch:
Editing the .json files and adjusting the Grbl settings should not be necessary (but is what some folks do).
First question is, which version of Carbide Motion are you using? If not using it, please try 649:
and re-run the Setup Wizard:
https://carbide3d.com/hub/docs/shapeoko-setup/
Note however, that Carbide Motion’s limiting of movement only occurs when jogging — it should be possible to move further either using G-code commands in a file, or at the MDI, or via a Quick Action.
All parameters for SO3 set up during configuration stop short of the physical limitation. I think is from the legacy of the Suckit dust collection that used to be very popular. The Suckit has arms that stuck out beyond the edge of the Z bracket so to keep from ramming your Z into the left rail they stopped short
How to Fix It:
Open Carbide Create
Go to the Help Menu
Open About
When that appears choose Open Data Directory
On my computer here is the result:
For me open the CarbideCreate6 directory
Look for the shapeoko.json file
Open the shapeoko.json file in a text editor.
Look for these parameters
“travelX”: -880.0,
“travelY”: -850.0,
“travelZ”: -140.0,
Modify the “travelY”: parameter. Try different numbers and save the file. In my case you see I set it to -850. I have an HDZ on a SO3 XXL. Your result may be different depending on what machine you have.
Just change the existing setting up. Then save the file. Close Carbide Motion and power cycle your Shapeoko. Power up the Shapeoko and Carbide Motioin and initialize and then jog to the far left. If it is still not going as far as you want then repeat procedure until you achieve desired result OR you hit the mechanical limit. You do not want to hit the mechanical limit.
The limits are for jogging only. If you write gcode that tries to send the Y axis a half a mile during running of your gcode the machine will try and obviously hit the mechanical stop. Jogging is limited by the settings in the shapeoko.json file. However gcode has no limit except the physical limitations of your machine.
Please report back if this works for you. It has worked for me.
I appreciate all your help Will. My tech just isn’t at the level it needs to dive into the GitHub stuff. I did open Carbide Create, went to About, selected show the data directory and was able to locate the Shapeoko.json. I edited the file with a text editor and my travel left is where I need it to be.
Thank you for all your assistance!!

Thank you Guy. This is exactly what I did. My old MacBook runs my cnc and for the life of me the carbide files were impossible to find. Not so on my new MacBook but I don’t use that one in my shop. Just resurfaced my wasteboard and everything is running well.
Thanks.
Steve
