I recently purchased a E3D supervolcano and am in the process of setting it up. As the heater draws 8 amps and my heated bed is already on a solid state relay I moved the extruder heater to the bed heater and attached my relay to the e0 heater. The extruder works fine but my bed will time out and fault when it is turned on. I am unsure of what I am missing to make this function. My heater setup from my config.g is:

; Heaters
M140 H1 ; Remap heated bed to heater 1
M307 H1 B1 S1.0 ; Enable bang-bang mode for the bed heater and set PWM limit
M305 P0 X200 ; Configure thermocouple for heater 0
M143 H0 S350 ; Set temperature limit for heater 0 to 350C
M305 P1 T100000 B4138 R4700 X0 ; Set thermistor + ADC parameters for heater 1 and remap it to channel 0
M143 H1 S120 ; Set temperature limit for heater 1 to 120C

This was generated using the RRF Config Tool but I believe it is correct.
Any help is appreciated.

Thanks for all the help, for the ethernet issues initially setting the ip to the same one as the router worked, but after restarting the duet it stopped working. Using a patch cable ultimately fixed the problem however. Not sure why it worked then stopped working though before switching cables. After getting into the web control it turns out that simplify3d was not correctly showing the temperatures of the pt100s or the thermistor when it was connected. One of the pt100s was actually faulty. I'm still having trouble getting both heaters to heat at the same time. I am using an e3d chimera so both heaters are different tools, is it by design that different tools cannot be preheated simultaneously? For your reference I am running firmware version 1.18.1. Thanks again for all the help.

Hey All,

I recently got a duet ethernet for a dual extrusion setup and am having two frustrating issues with it. The first issue is related to the ethernet connection and the second is related to my heaters and PT100 sensors. For the ethernet issue I cannot connect to the Duet Web Control at all. I have tried reinstalling the newest file to the www folder and setting a static IP. My router sees the Duet when given a static IP but the M552 command says the ip is 192.168.1.120 which is what I set it to, while my router sees the ip as 192.168.1.137. I am getting no flashing lights on either the duet or my router's ethernet ports. Additionally, the lights on the duets ethernet port DO light up when plugged into a PC. If anyone has any clue of something I could be missing I'd greatly appreciate it.

As for my second issue, I have 2 extruders set up with 2 PT100 sensors. Both sensors are reading correct temperatures and woirkinded fine on their previous setups, however only the hot end connected to RTD0 works. I have tried physically switching sensors to see no change. I have switched which hotend is set to RTD0 and RTD1 and continue to only get heat when connected to RTD0. It gets weirder because when I tried only configuring 1 hotend both RTD0 and RTD1 worked fine when switching configurations. I also tried setting the second hotend to ADC2 and that allowed both heaters to turn on separately. In this set up both heaters still would turn on concurrently. I am stumped as what to try next, could it be a board failure of either the PT100 expansion on the duet ethernet itself? Again any help is appreciated.

Thanks in advance
