I just got done assembling my MPCNC and can’t seem to get the connection on Repetier. The Rambo board does not show up at all in windows explorer to say that the usb connection is there. Attached is my hookup for my board and the issue screen I am seeing. I followed the tutorials for setting up Repetier but still getting the issue.
I bought all the hardware, motors, and such from Amazon or locally. I bought the series wiring harness and the Rambo board from the site.
Make sure the usb port is correctly selected and the power is on baud rate is 250000. If possible try another usb port. Or show the repetier settings screen.
The only other thing is if you mistakenly powered it backwards, even for a half a second you can pop the little fuse. I mention this for people not using the 6 port plug, the four port can miss the right pins and pop the fuse as well.
I can run the cnc without being hooked up to the computer. I started out with an LCD display then decide a computer would be better to run the cnc with. I only moved around in the x, y and z axes. Didn’t run any code through it yet. I get the green light on the board when the power is on.
I’m on windows 10. I installed the Arduino IDE app through the App Store and then also the full desktop download from the website as well. I still wasn’t able to make it work. But I will try the suggestions you and Ryan have given. Thanks in advance.
Hey Ryan I have installed Arduino 1.8.7 from the Arduino website. The usb drivers and everything else is installed. I have the green light on at the Rambo but still nothing showing up on the computer saying that the board is there. I have tested all the USB ports I have on the computer but still can’t get it to show up. Any ideas here?
This will be the second computer I have tried this on. Not sure what else I can do? Reflag the firmware on the board? This doesn’t seem needed bc I can run it through the LCD screen.
I have gotten it to work!! Thanks for all the help and advice. Now I can start some drawing and then hopefully move on to the MP3DP. Thanks again guys!
I deleted the repetier server like you said. Then I went through the USB ports one by one option wise till it connected. Eventually I found the right one.
