I have installed homing switches and they appear to be working, I can home. I am ready to try to update the GRBL to 1.1 so I can use Carbide Motion 4. When I run the update program everything stays gray, no green check marks. Nothing happens. I am connected to my machine and it is powered on. When I click the Search For Machine button the Scan Ports green check mark will always appear and also Confirm Reflashing. If I select my machine while holding the z-axis limit switch in, nothing happens, have held for a couple minutes. Any ideas? I am stuck.

Please try one of the other flashing programs:
Windows: http://russemotto.com/xloader/
Mac: http://paulkaplan.me/HexUploader/
Or the Arduino SDK: https://github.com/grbl/grbl/wiki/Compiling-Grbl per https://github.com/grbl/grbl/wiki/Flashing-Grbl-to-an-Arduino
You can grab a copy of the hex file from: http://carbide3d.com/dl/v4/grbl.hex
If that doesn’t work, contact support@carbide3d.com — suspect you don’t have a bootloader loaded and we’ll need to swap out your board (unless you have a spare Arduino or a special tool for programming the bootloader).
After we download the uploaders…what settings do we use?
