I was running a print job with Cura and hit the cancel button.
The printer stopped in it’s track and then lost connection with Cura so I couldn’t move the X,Y, or Z axis. Also the temperature readings stopped showing on the Cura screen.
I tried clicking on the “Connect” button. It said “Connecting to Serial” (or something similar) then said “Closed”.
I’ve rebooted both the PC (Windows 7) running Cura and the Printer several times to no avail.
The printer is getting power. The extruder fan is running and there is LED light coming from inside the electronics box.
Hmm, try a different USB port? That or grab a copy of prointerface and see if the printer will accept commands from it. Did your serial com port happen to change?
Hmm, it’s probably not your computer then, and the Rambo board wouldn’t be doing anything if it was fried. The Mini doesn’t have an LCD so it’s probably not likely that the auxiliary e-stop is tripped. There is an onboard reset button, is it possible that is pressed down somehow? It’s next to the USB port. If it isn’t that, the only thing I can think of is that somehow you wiped your rambo board. If you are under warranty you might want to call support.
There is nothing touching the reset button. I know exactly where it’s at.
What do you mean by the board being “wiped”? Do you mean the firmware could be gone?
Also, the USB plug was recently replaced bu the printer has been working perfectly ever since. However, if one of the leads on the USB plug has become faulty could that cause the PC to detect the board while at the same time not allowing the software to connect?
The connection speed is 115000 at most - otherwise you are communicating faster then the Arduino can talk reliably.
The control board fan should ‘blip’ on during connection then stop again until the heat levels turn it on again. But no connection = no fan turning on.
when you say USB plug was replaced, do you mean you swapped out a card on the computer side, or the port on the Rambo board itself? if you soldiered a new USB socket onto the Rambo board, something very well could have come unsoldiered due to heat.
The card was not swapped out. I wasn’t there but from what I understand the printer was moved and pressure on the end of the USB cable damaged the USB plug/jack. The plug on the board was then replaced.
