Okay, so here is my problem: I need to modify the firmware so that the when preheating before a print, if the bed heater goes over target, the printer doesn't wait for it to come back down - it starts the print. However, if below the target, it still waits to hit the target or go over it. Is this an involved modification or is it as simple as commenting out some lines of code? I've searched through the PID settings for the bed heater and haven't been able to find anything.
Before anyone suggests a work-around such as preventing overshoot in the first place (through K values or better thermal connection of thermistor), that's not what I need. This printer has been excessively modified to be a paste extruder. I have a heated syringe nozzle rigged to the bed heater. I'm not gonna get into it but all I need to know if this is possible to change in the logic, not how to prevent the issue in the first place.
I'm using a RAMPS 1.4 board from sainsmart, running the most current version of Marlin.
Thanks!
