Gsender Greyed Out?

I have today for the very first time plugged in my homebuilt CNC, luckily everything started up with no bangs or smoke as I’m no electrician and have had to learn from articles and YouTube as I went along I am using an Arduino Uno R3 with Grbl and gSender as the control software.

When I opened gSender I was able to connect to my Arduino on com3 but all the controls on the screen remained greyed out and at the top of the screen it says “Disconnected”, could anyone please shed a little bit of light on what I have done wrong or haven’t done?

Hi Lee,

There is a section in classic gsender manual discussing what seems to be your problem. I have printscreened this section of the troubleshoot pages.

Found here:

Hope a solution to your problem is listed here.

Thank you Eddie, I will take a look tomorrow, I’m hoping it’s something simple!
