Max Z axis travel?

It looks like my Z axis can go down a little more. Should it be able to?

I tried increasing the Z Max travel parameter from my default $132=94 to $132=96 but it did not seem to increase the travel.

Adjust the Travel Dimensions in Carbide Motion | Settings if your steps/mm for Z in Grbl for $102 are correct (should be 200 for a Z-Plus).

Carbide Motion also has a size limit. If you’re on the newest versions of CM you can alter it to suit your machine. I increased my Z and Y travel in the settings screen to maximize them.


Will Adams posted this a while back about the Shapeoko Specs.

Shapeoko Default Sizes for GBRL Configuration

To allow folks to confirm their Grbl configurations, here are the settings for:

Setting Belt Drive Z-axis Z-Plus (inc. Pro) HDZ
$100 40 40 40
$101 40 40 40
$102 40 200 320

The Travel Dimensions for the various machine sizes and options are:

Machine size and Z-axis type X Y Z
Shapeoko 3 Standard Belt Drive 420 430 100
Shapeoko 3 Standard Z-Plus 420 430 95
Shapeoko 3 Standard HDZ 420 430 140
Shapeoko XL Belt Drive 830 430 100
Shapeoko XL Z-Plus 830 430 95
Shapeoko XL HDZ 830 430 140
Shapeoko XXL Belt Drive 830 850 100
Shapeoko XXL Z-Plus 830 850 95
Shapeoko XXL HDZ 830 850 140
Shapeoko Pro XL 870 440 95
Shapeoko Pro XXL 870 850 95

Note that it is possible to increase X-axis travel if using an HDZ w/o a dust collection system which limits X-axis travel.


Is there any way to see what the steps/mm for Z, X, and Y currently are set to for a Pro XL.
You said the code # is $102 for Z .
What is it for X and Y

$100 for X and $101 for Y


for details.
