High temperature print head-remove 260 degree lock

[sergiucip 0]

Hello,

I need support from you guys, please!

I need to figure out how to increase printhead temp above to 260 centigrade. I know this limit is for safety reasons.

The max temp i need is 280 degree for printhead and 120 degree for heated bed.

I already have reinforced PTFE coupler (high grade material reinforced with fiber glass, wich is suposed to suport 280 degree without problem), and a silicone 120 watt 220 Volt heated bed with solid state relay.

in configuration.h if i modify temp values nothing happen, the temp for nozzle doesn't rise above 260 and for bed 105 degree.

#define HEATER_0_MAXTEMP 275

#define HEATER_1_MAXTEMP 275

#define HEATER_2_MAXTEMP 275

#define BED_MAXTEMP 130

I know the software measure curent and doesn't allow the nozzle heat above 260 degree ,same algaritm for bed.

Please help me, now i use ultimaker 2 jar jar wich let me to print in 265 degree for printhead and 115 for bed.

I need 280 degree for head and 120 degree for heated bed

Thank You for your support!

Temp limit is always 15more than the highest you can use. So to use 280 set 295 on that maxtemp definitions
