Remove heatbed completely

FoxLab

In a previouse thread I have already described that I'm working on a "lioquid" printer which does not require any heating.
This also applies to the heatbed which is not required.
I have played around with the heater asignment in config.g by disabeling the corresponding g-code lines like this:

; Heaters
;M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
;M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
;M143 H0 S120 ; set temperature limit for heater 0 to 120C
;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

My particualr goal is to compleetly disable the heatbed and mak it either invisible on the DWC and PanelDue.

Thank you

@FoxLab Put this in config.g to disable the bed completely:

M140 H-1                                    ; Disable heated bed

Thank you, this worked. DWC now does not show the heatbed anymore. But PanelDue still shows a heatbed. Is there a way to eliminate this?

The PanelDue firmware is a lot more rigid in how it handles heaters. It expects there to be a heated bed as H0, and then extruder heaters sequentially after that. Unfortunately that's a hard limitation at this time. Though it is on the work list to improve how it handles heaters.

PanelDue is open source... and taking something out would potentially be a lot easier than putting something in.

@FoxLab @Phaedrux I wrote this caveat recently, just updated with the above: https://duet3d.dozuki.com/Wiki/Connecting_an_LCD_control_panel?revisionid=HEAD#Section_Limitations
