Hi,
I am a first time builder working on a prusa mendel with RAMPS 1.4, 100k glass thermister and I uploaded marlin firmware.
For some reason, when I load ponterface it reads room temperature between 100-110 degrees. When I try to heat the hot end it will heat to around 170 degrees, but that seems to be its limit. However, I do not have a laser thermometer to test what the real temp is.
I have checked the wiring and firmware several times and do not see any issues. Has anyone else had this issue? Any idea on how to fix this?
Thanks,
Steve
