Follow these steps to reset your controller to the default settings using Carbide Motion 3

Step 1: Connect to your Shapeoko through the version 3 of Carbide Motion.

Step 2: Click the Settings tab

Step 3: Click the Log button to bring up the log window

Step 4: Click the Info button

Step 5: From the info pane, you can load the default Values by pressing ⌘+1 (ctl+1 on windows). You will see the values begin to scroll through the log on the right. Once the values have been sent, you can close the log window.

The default GRBL settings for a Shapeoko 3 without homing switches are as follows:

$0=10 (step pulse, usec)
$1=255 (step idle delay, msec)
$2=0 (step port invert mask:00000000)
$3=6 (dir port invert mask:00000110)
$4=0 (step enable invert, bool)
$5=0 (limit pins invert, bool)
$6=0 (probe pin invert, bool)
$10=255 (status report mask:11111111)
$11=0.020 (junction deviation, mm)
$12=0.010 (arc tolerance, mm)
$13=0 (report inches, bool)
OBSOLETE, SHOULD NOT NEED TO BE SET: $14=1 (auto start, bool)
