Have a new grblHal breakout board v2.07 fully built.
Have uploaded the 'grblHAL_T41 3X qei.hex' with the Teensy loader.
Installed ioSender 2.0.36 on windows 11
Have one DM556 stepper controller connected to the X axis connections with a bi-polar CUI stepper attached to the stepper controller.
Nothing else is connected to the board other than the USB power from the windows PC.
When I launch ioSender 2.0.36 (with the DM556 attached or not attached) I get the ALARM:10 error: "E-Stop active! - clear before continuing..."
After acknowledging the message, I get E-Stop still active, exit?" message and am unable to to any other actions.
What I am doing wrong?
