a few years ago I decided to get into the cnc mill/laser hobby. I bought a MPCNC kit with the mini Rambo board. Then I found out I had to learn how to cad/cam and had a kid. so things sat for a while. I decided to pick it back up and had a true idiot error with Estlcam. Since the board came preflashed it worked great but then, for reasons no one can explain, decided to press this button:
Then I tried “restore controller” from the same page. Nope.
Since my board was non responsive, I thought “OK there are great instructions on V1 to re-flash the board”. No dice.
Repiter and Estlcam cannot talk to the board. I have verified the driver is installed and the com port is correct, including the baud rates and other settings, but I am at my wits end with it.
I am reaching out with hope that the community here can help me resolve my issue or tell me that I can replace the board with a slk mini 1.2/tft35 I have laying around or an new control board I was gifted from a 3018 pro that runs grbl. I prefer to resolve but am wiling to do what I must to get my mill operational so I can start making chips.
When you pressed the “Program Controller” button, Estlcam overwrote your board’s firmware with a proprietary version. Unfortunately “Restore Controller” just puts a plain vanilla version of grbl back on, not whatever was on it before. Like Dan said, you will need to reflash the V1 firmware back on your board.
I will try to reflash it with Platformio. I did try to reflash it with Arduino 1.8.13. the package verified and it said it loaded. That is why I don’t understand why it is not connecting.
So I finally got the firmware loaded via Xloader with the help of another thread.
When I open Repiter, and connect, I am getting this error now:
I have no movement and I get command waiting form Repiter. Any suggestions? I have verified the com port and Xloader commed on this port. The baud rate matches.
