From b1676c7b299b36cf4f056cfcfb67e6334efe9199 Mon Sep 17 00:00:00 2001 From: Kreyren Date: Sat, 19 Feb 2022 19:41:27 +0000 Subject: [PATCH] Update Configuration.h On my stock Creality Ender-3 the PTFE bowen tube melts and starts to burn when it reaches 260 C that the printer allows out of the box, this commit decreases the HEADER_X_MAXTEMP in Marlin to decrease the max safe temperature to 240 to avoid this fire hazard. This issue can be reproduced by using 260C hotend temperature on the printer without the filament and the PTFE bowen tube should start to smoke and burn in <50 sec --- .../Marlin/Configuration.h | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/Ender-3 Firmware (Marlin)/Ender-3 (includes power failure resume- English)/Marlin/Configuration.h b/Ender-3 Firmware (Marlin)/Ender-3 (includes power failure resume- English)/Marlin/Configuration.h index 1b58269..3d247ea 100644 --- a/Ender-3 Firmware (Marlin)/Ender-3 (includes power failure resume- English)/Marlin/Configuration.h +++ b/Ender-3 Firmware (Marlin)/Ender-3 (includes power failure resume- English)/Marlin/Configuration.h @@ -322,11 +322,11 @@ // When temperature exceeds max temp, your heater will be switched off. // This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure! // You should use MINTEMP for thermistor short/failure protection. -#define HEATER_0_MAXTEMP 275 -#define HEATER_1_MAXTEMP 275 -#define HEATER_2_MAXTEMP 275 -#define HEATER_3_MAXTEMP 275 -#define HEATER_4_MAXTEMP 275 +#define HEATER_0_MAXTEMP 255 +#define HEATER_1_MAXTEMP 255 +#define HEATER_2_MAXTEMP 255 +#define HEATER_3_MAXTEMP 255 +#define HEATER_4_MAXTEMP 255 #define BED_MAXTEMP 125 //===========================================================================
