Multiple heated chambers (printing + filament) – how to?
-
Hi,
sorry as I'm new to this board, but I would like to ask a question. I would like to set a multiple (two) heated chambers on RepRap Firmware 3.x
I have nicely set main extruder heater, bed and chamber, but can't get another tool + thermistor paired together so I can use those for setting it as another “pseudo chamber” (it wouldn't be called via M141 obviously).
Problem is just that I can't get that second extruder paired with thermistor. Tool 1 doesn't have thermistor assigned and thermistor itself is showing in Extras.
I have Duet 2 Wifi + Duex5 for more heater and thermistor pins.My config:
; Thermistors M308 S0 P"bedtemp" Y"thermistor" T100000 B4725 C7.06e-8 ; Put your own H and/or L values here to set the bed thermistor ADC correction M950 H0 C"bedheat" T0 ; Create bed heater and assign S0 thermistor to it M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M143 H0 S200 ; set temperature limit for heater 0 to 200C M308 S1 A"Extruder" P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin e0temp M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1 M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H1 S450 ; set temperature limit for heater 1 to 300C M141 H2 ; heater 2 is a chamber heater M308 S2 A"Chamber" P"e1temp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 3 as thermistor on pin e1temp M950 H2 C"e1heat" T2 ; create nozzle heater output on e1heat and map it to sensor 2 M307 H2 B1 ; use bang-bang mode for heater M143 H2 S180 ; set temperature limit for heater 2 to 180 C M308 S3 P"e2temp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 3 as thermistor on pin e2temp M950 H3 C"e2heat" T3 ; create nozzle heater output on e1heat and map it to sensor 3 M307 H3 B1 ; use bang-bang mode for heater M143 H3 S100 ; set temperature limit for chamber heater 2 to 100C ; Tool definitions M563 P0 D0 H1 ; Define tool 0 G10 P0 S0 R0 ; Set tool 0 operating and standby temperatures ;*** If you have a single-nozzle build, comment the next 2 lines M563 P1 H3 ; Define tool 1 on heater 3 for filament chamber heater G10 P1 S0 R0 ; Set tool 1 operating and standby temperaturesPlease ignore thermistor type used, it's just for testing.
As I'm saying, topic might be called “Dual extruder and chamber” as I'm aware I can't use two chambers, but I would like to use another thermistor and heater output as an separate chambers for printing and filament heating chamber.
