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

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?

@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.

@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.?
