Hello. I’m getting back to the MPCNC project after most of a year off. Retirement and other projects got in the way. I smoked the MEGA under my ramps board back then. Machine moved and made the crown. I was working on calibration.
Fast forward to now. I bought mini-RAMBO 1.3 from Utili-machine. I have followed instructions here: https://www.v1engineering.com/marlin-firmware/ My computer shows Rambo hooked up, and the mRambo sketch compiled and loaded with no hesitation. With ESTLCAM I can program the controller and it seems happy. Using the manual controller, F2, I can see yellow lights in center of mRambo brighten, then normal flashing resumes. No movement of motors, no hum, nothing.
It most certainly is not happy if I am understanding you correctly.
You use estlcam to make gcode, at no time should you try to control your board with it. You will now need to re-flash with my firmware and follow the crown getting started steps again.
A day later… Replayed the Arduino set-up and reflashed the firmware with marlin.ino dated 1/1/2019. Repetier-Host will connect with the mRAMBO. When I sent manual move instructions I can see a yellow blink but no motor movement.
In checking wiring I found I had inserted the power jack backwards. When I turned it around red pilot light came on. Checked fuses, they are good.
I’m beginning to suspect I cooked the regulator on the mRAMBO.
Double check use the link I just gave you, flash it again, make sure it says successful. The red light is not good, 95% chance it means wrong firmware, 5% chance it means broken board.
Downloaded link, reflashed. Says it was successful. No joy.
Windows 10 computer shows Arduino Mega 2560 on Com3.
Computer gives me the connect and disconnect sound when I plug and unplug.
I’ve tried two different cables from computer to mRAMBO board.
Repetier Host will connect and disconnect.
Dialogue box says: No Start signal detetected - forcing start.
Manual move does nothing.
No holding current to motors.
Found driver link on utilimaker site. Computer sees rambo board. Arduino lets me flash firmware “marlin” from the page listed above. Repetier-host will connect but gives error message.
