I hope to resume printing quickly;)
PS: why the T2 pin is burned? I fear that happening to other pins? And if it happens, what should I do?
I'm glad the the pin changes worked and you were able to use a different thermistor port. Good job in doing the pin remapping.
The version 1.1 series of the Rambo board are sensitive to static spikes and other potential sources of voltage on the thermistor ports and a capacitor
on the ports opens and the port stops working. Ultimachine is aware of the problem and the design of the new 1.2 series of boards have built in circuitry
that helps to stop that from happening. Those of us who own the older revisions have to remap the pins and use a different port which is what you had to do.
If you run out of ports you would have to send in the Rambo board for repair, fix it yourself if you have the knowledge or buy a new board. That's just the way
it is and Ultimachine did come out with the new version which shows they are pro-active in fixing these kind of problems when they come find them. What bothers
me is that I asked another user to look at my pin remappings and let us know if they looked correct and not one person on this forum responded. We are here
to help one another and it seems at times users forget that.
Anyway, we got you up and running again so I'll close with my favorite ending - Happy Printing!
