  We buy them from Digikey, but we had to wait for our most recent delivery.

  @simonboydfoley said in Voltage of heater 2 (E1) drops when enabled?: Hi @dc42 yes I connected the Duet E1 Output to the SSR input That doesn't answer my question. How exactly have you connected the two SSR input terminals?

  Thank you very much! The updated documentation also answers my question whether or not a PanelDue is required (it's not). I ordered my Duet Wifi today.

  @yoyobob19, I didn't see a pic. I suspect a faulty (perhaps intermittent) E0 stepper driver, or possibly a bad connection on the Duet; but please post your config.g file first in case of a problem there.

  @dc42 Yes exactly, I have to consider changing the stepper and test again thanks.

  @djdemond I've noticed that too when searching the forum reading older threads where they are obviously referencing some images, but there is nothing there. Very confusing.

  In your photo, which wires go to the Duet - the green ones at the bottom, or the black/blue ones at the top - and which to the sensor?

  @mike, according to my measurements a hexagonal plate that is 303mm across flats would just cover the horizontal extrusions without overlapping them. As the extrusions are 20mm wide, the mounting screws would need to be set 10mm in from the edges. Caution: these figures may be 1mm (or more out).

  Just as FYI, this is the peltier we bought and will be using.

  Thanks for your reply. I ended up wiring it like this in case someone else comes across this issue: Prusa PINDA Probe +------------------------------------------------+ | | BLACK BLUE BROWN (SIGNAL) (GND) (+5V) + + + | | | | | | | | | +-+-+ | | | | | | 4.7kΩ | R | | | | | | | +-+-+ | | | | | +-------+ | | | | | | | | | | | + | | | | +---+---+ | | | / \ + | | | / Z \ | | | / D \ | | | / 3.3V \ | | | +---+---+ | | | | | | | | | | | +--------+ | | | | | | | | | | | | | | | | | V V | | | V +------------------------+ Duet3D Expansion Header Duet3D Z_Probe_IN Pins 2 & 1 (GND, +5V) (in different setups another resistor might be more suitable!)

  Hi Guys, I have connected a diode to the sensor, with anode side(no line on the plastic) into the connectors on the duet wifi, and the cathode side(line on the plastic) into the wire on the sensor itself. LJ12A3-4-Z/AX When using either E0 STP pin or the Z STP for the sensor signal no light comes on. i.e. when the probe is triggered the red light is turned off, when the probe isn't triggered the red light is on( in my case the lights have never been on to begin with) Please Help as this is making me pull my hair out. At the moment the sensor is connected to the E0 Connector The code is as follows: ; Endstops M574 X1 Y1 S1; M574 E0 Z1 S0; M558 P4 X0 Y0 Z1 E0 H10 I1 F80 T6000 ; for inductive sensor, Set Z probe type to switch, the axes for which it is used and the dive height + speeds M557 X0:170 Y13:180 S25; Define mesh grid G31 P1000 X0 Y0 Z0; Set Z probe trigger

  Timing... I had some foot surgery so I'm stuck at home for the next 3 weeks, and Tony Lock at Think3DPrintD sent me a Duet and Panel Due that arrived the day before the surgery. I'm having a little trouble moving around right now, so I sit at the computer with my foot elevated and plan. In a week or so, when I can move around more comfortably, I'll start the rewiring.

  You can connect the pairs of winding in either series or in parallel, whichever gives you the most suitable rated current and inductance. Parallel connection will give you double the rated current and one quarter of the inductance compared to series connection.

  Just make sure that they can't short together.

  @dc42 said in Unstable temperature readings during heating: It sounds that you have insufficient thermal insulation underneath the bed heater. This is true. Unfortunately I haven't found the right case for the Duet to isolate the flow from the cooling fan, and have deferred the cork base until I receive the 240V heater - so resolution of this is in the works, however this isn't the cause of the erratic temp readings.

  @dc42 Thank you that fixed it. I see how that would work, not sure whether to feel embarrassed at not having spotted it - or peeved that it accepted a 'default' that I never intended . Sorry to have troubled you!

  The 1.02 and later revision Duet PCBs have built-in flyback diodes. The earlier ones don't. Are you fan-cooling the area of the board with the fan mosfets? At 1.5A continuous current they will get hot if you don't. Fans 0 and 2 shouldn't blip on startup. Fan 1 will because it defaults to being on, for maximum safety when it is used to control the hot end heatsink fan.
