@JamesM Thank you, that's what it was. I had a 10amp AC plug sitting here. Switched it out and it worked. Got my pid tuning finally done.

I'm having issues with getting my bed heater to work. It's a 110v ac unit. I have it wired to a SSR. Picture below is how it's wired.

I've also tried with the wires connected opposite on the psu. To clarify the bed heater is on the AC side of the psu, as the bed heater is AC. This way I didn't have to redo my wiring at the power adaptor . When I try to heat the bed, it blows the fuse in the power plug. I'm trying to do a M303.

Is it blowing the fuse because it's also connected to the PSU, the PSU is a Mean Well 600w? Do I have to wire it directly to the power plug?

I got the replacement, the temp reading works now. Thanks for all the help.

@Phaedrux Ok will do, thank you.

@dc42 Yes, that would be great. Thank you. What all do you need?

@Phaedrux said in Pt100 reading 2000C:

So the PT100 itself measures ok at the connector end?
And the wire going from the smart effector to the daughter board tests ok?
It's only when the PT100 is connected to the smart effector that you can't get a reading off the back side of the connector pins?

Can you get a close up of the PT100 connector on the smart effector with it disconnected?

It's out of warranty period unfortunately, as it's 6 months, but hopefully it's not unfixable. Might just need to reflow the back side of the pins on the smart effector. If we can't get it sorted out we might be able to do an exchange at a reduced price, but would depend on availability.

Sorry for the delay, I work 2nd shift and I'm eastern standard time.

1.So the PT100 itself measures ok at the connector end? Yes

2. And the wire going from the smart effector to the daughter board tests ok? Yes

3. It's only when the PT100 is connected to the smart effector that you can't get a reading off the back side of the connector pins? Yes, I get no reading from the white connector.

If you need anything else just ask.

@Phaedrux ?

@Phaedrux filastruder.com, Aug 2019. Life happened and I didn't get to putting the rest of my printer together till now.

Edit: I also have the z bed leveling hooked up through that connector also, just haven't got far enough with the setup to see if that is working or not.

@Phaedrux Here is a top one and two bottom ones.

@Phaedrux With the green coating I can't see any traces. I don't see any damage. What areas do you need pictures of.?

@dc42 Yes, they are all there and solid.

@jay_s_uk
No, the wiring is good. I'm getting resistance at the black connector on the bottom of the effector, but not on the top white connector on the top of the effector.

@jay_s_uk
Yes, they are in the picture above. I'm also using pins T2 and T3, the connector is working I checked the soldering points on top of said connector and I got 110 ohm, just nothing at the top connection.

Edit: I also verified I am on firmware 3.1.1, M155 is not the command though, its M115.

Ok, it is an E3d PT100, I ordered it from Filastruder.com, it does have red wires.

I have found the problem, not sure what's the issue though. I have a duet3d Smart effector, I tested the PT100 at the connector, before plugging into effector, I get 110ish, checked at the top connection, that goes to the wiring harness, I get nothing. It seems the effector traces are broke or something, I have no idea. There's something about jumpered for 2 wire by it, no pictures show anything about that, nor dooes duets instructions. Anyone have any ideas?

Here you go.
@jay_s_uk

I've searched everywhere and can't find any answers. The PT100 is reading 2000C.

The pt100 is connected to the daughterboard in pins 2 & 3, I have the jumpers on all four pins. They are connected to the first set on the daughterboard from the left, reads rtd1.

Here's the config for the heaters: Firmware 3.1.1 Duet 2 WIFI

; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 ; configure sensor 0 as thermistor on pin bedtemp B4138 M308
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
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 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"spi.cs1" Y"rtd-max31865" ; configure sensor 1 as thermistor on pin
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00

When I try a 100 ohm resister it read -2.9c. When I check the ohms on pt100 is shows 1050 on my meter, I can check again if anyone wants.

What is wrong? Research and changing stuff for the last 6 hours, I'm at my wits end.

thanks.
