Marlin, Preheat can't be changed
November 21, 2014 12:01PM
Hi, I'm struggling to change my PLA preheat values from 190 to 200 and bed from 70 to 35.

I change them in config.h file and upload successfully, but still it's default values.

Heres my config:

[pastebin.com]

// Preheat Constants
#define PLA_PREHEAT_HOTEND_TEMP 200
#define PLA_PREHEAT_HPB_TEMP 35
#define PLA_PREHEAT_FAN_SPEED 255   // Insert Value between 0 and 255

You have EEPROM_SETTINGS enabled in your configuration.h, and according to the configurationStore.cpp file, the preheat parameters are some of the variables stored in EEPROM. I believe EEPROM settings take precedent over firmware settings, so what's likely happening is *old* settings in EEPROM are taking precedent over what you're trying to change in a firmware update.

One way to work around this would be to go to Control/Temperature on the LCD and then scroll down to PLA PREHEAT CONF. Set the preheat values how you want them, and then scroll back up and perform another store memory to update the EEPROM settings.
