Description

Hi there,

I'm working with a new Dual Zone Heatbed, it can be controlled via the RAMPS, however i want to be able to read each Zone's Temp independently, is it a huge task to add Support for another Heatbed ##Therm input? I was going to just register it as another Hotend, but ideally want it to be displayed as a second heatbed on the Full Graphics LCD.

Thanks

Alex

Contributor guide

Research direction
Investigate how the existing single heatbed is handled (thermistor reading in temperature.cpp and display in ultralcd.cpp). Understand the data structures (thermalManager t) and extend them to support a second heatbed thermistor. Add configuration options in Configuration.h and update the LCD to display both zones.
