gSender 1.4.6 grbl-hal with the SLB

After getting everything up and running I noticed that I can no-longer control the speed of my spindle from the gSender screen. The speed control slider that was under the feed control slider is no-longer there. Am I just missing something in the firmware settings? I’m using the PWNCNC 1.5k spindle. This slider was handy to be able to override the spindle speed during a job run.

Do you have spindle functionality enabled in preferences? Both the spindle widget tab and the speed overrides are hidden unless you have Spindle/Laser turned on.
