From looking at the comments in the code I though the same thing about PID not being used during warmup. However I tried it anyway and it did not seem to make much of a difference. Another interesting thing I've found, the 1.0.0 firmware shows a nice smooth curve int the temperature graph when warming up. However the 1.1.0-rc3 firmware has the same smooth curve up to 40 deg. Then it shoots upby edog1973 - Reprappers
Floyd, thanks for the quick reply: Here are the relevant (I think) sections from the Configuration.h files Old 1.0.0 Configuration.h // Bed Temperature Control // Select PID or bang-bang with PIDTEMPBED. If bang-bang, BED_LIMIT_SWITCHING will enable hysteresis // // uncomment this to enable PID on the bed. It uses the same ferquency PWM as the extruder. // If your PID_dT above is the defaby edog1973 - Reprappers
Hello all, fairly new to the RepRap world. I recently built a Prusa i3 using the Folgertech 2020 kit. I started by installing the vendor supplied Marlin firmware version (1.0.0) and have been able to make some decent prints. Then I installed the newest Marlin firmware from github (1.1.0-RC3) and updated Configuration.h using the vendor firmware as a guide. Again I've been able to make someby edog1973 - Reprappers
