I am using ramps 1.4 and arduino mega 2560. The bed heats up, hotend starts to heat but stops 2 degrees before 205 setpoint.

Any help would be appreciated.

Thank you,
Gary Clair

Did you mean to post that question to this section of the forum? The Ormerod works with Duet electronics, not RAMPS/Arduino.
