after the

command

B0 Disables Bang Bang and enables PID mode.

M950 H1
im still on firmware version 2.03

Veti

@tracar

you should at least update to 2.0.5.1. That should work without config adjustment.

However at some point you have to invest the time to update to rrf3

Veti

@tracar

in rrf2 place it after the other M305 commands.

like this ?
; Heaters
M305 P0 T100000 B3724 R4700 ; set thermistor + ADC parameters for heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M305 P1 T100000 B3724 R4700 ; set thermistor + ADC parameters for heater 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C
M307 H1 A869.9 C308.4 D3.1 V24.2 B0

Veti

B3724

where did you get that value from?

tracar

@Veti
M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0

reduced the 4138 by 10%

tracar

@Veti

the bed has the exact same thermister..

Veti

@tracar said in My corexy hbot configurations and build pictures:

that was for the A Parameter of M307 if you have overshoot. not for the B Value of the Thermistor. Overshoot has nothing to do with the thermistor. The B Value of the thermistor is to calculate the temperature based on the resistance of the thermistor. if the beta value is wrong the displayed temperature is wrong.

i.e it could show 240 C but the actual value would be 200 C

@Veti
i have changed it back to the default values.

so when i run the M303 H1 S240
the testy begins, finishes and i can display the results with M307 h1.

do i have to manually enter them only once in the m307 line, OR is this automatically enterd? or how and what do i need to add to do this automatically?

Veti

@tracar

you have to save it manually in the config.g as it is written in the guide (as you have not enabled the M500 command for you config)
