Welcome to the SeeMeCNC Community

Ok so after some searching and diagnosing, I found that I have a blown MOSFET for HEAT 1. I want to change the pinout in the pins.h file and use HEAT 2 instead (I will not use dual extruders on this printer anyways). Now I need to know what exactly to change in the pins.h file because I do not want ...

Ok so I was gone for a few days. Now when I try to heat my hotend, it does nothing. I tested the hotend heater resistance at the board (with the pins on the bottom) and it was at 4.6 ohms so that rules out the crossed wire. Then I turned the hotend on in the software and it was reading 0.1 volts ...

OK sounds great thanks.

Yes I am from Nappanee, Indiana. I have actually been to the SeeMeCNC shop several times and purchased my RAMBo board from you.

Hello I have a PCB heatbed on my RepRap Prusa Mendel with RAMBo board. I am using repetier firmware with Repetier-Host software. For some reason my heat bed cannot heat above 95 degrees Celsius. I set it to heat to 115 C and it heats up until it eventually hovers around 94.7 degrees. If I set the ...

Ok so I am just starting with a 3D printer. I have a RepRap Prusa Mendel with RAMBo board. I am using repeiter-host to control it. I loaded a 20mm cube for my first print (got the STL off of thingiverse). I heated up the bed and exturuder, then clicked "run job". After seeking home, my printer moved ...

Hello my name is Jeff and I am new to 3D printing. I just built my first RepRap Prusa Mendel with a RAMBo board. I had no idea what I was getting myself into when I started this project, but I am slowly starting to understand the concepts of the machine. Like I said, I am new to printing and am just ...
