Craig, I’m sorry to have kept you waiting in silence for nearly a week.
For the last few weeks, I have been trying to get through shipping and doing support on nearly double our typical order volume.
Unfortunately, as I sometimes forget, any response is better than a shiny comprehensive response, the latter being what I have been working on for you in my head for the last bit of time there.
The highlights of that response include:
- I haven’t personally experienced it, but I have heard some users talk about how grbl-lpc can be “sticky” on the board.
- Try disconnecting everything from the board (you did this, great!)
- Try flashing the new firmware onto the board, try a different SD Card, format, etc…
- Depending on how you are powering the board, and what the power supply on the other end of that picture is, you may need to try powering the board from a good power supply, or the USB cable.
This is the firmware file you want to use: Improved Raster Speed Firmware Update for Cohesion3D Boards!
The LEDs will do “flashing firmware” as shown here when it takes: Cohesion3D Board Indicator Status LEDs
Please let me know how this goes.
I can understand being frustrated, but it is just me trying to hold down the fort here and I’m trying to do that and get out with a tiny amount sanity at the end here. I am not trying to leave you hanging, I want to help, I just need a bit of breathing room.
