Pt100 reading 2000C

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.

I would suggest you have a dodgy crimp or a break in a cable between the smart effector and the daughter board.
Use your multimeter to check the cable. You should have a low resistance on each one.

Bloodember

@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.

Are the pins of the white connector all soldered to the PCB? That connector is hand soldered, so it's not impossible that pins are missed.

Bloodember

@dc42 Yes, they are all there and solid.

sorry about that.

Photo of the effector? is there a damaged trace?

Bloodember

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

Phaedrux

Front and back if possible, maybe a close up of the PT100 connection.

Bloodember

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

Phaedrux

The pins don't look too bad, but if you're unable to read the PT100 from the back side of the pins on the effector something isn't making a connection obviously.

When and where did you purchase the Smart Effector?

Bloodember

@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.

Bloodember

@Phaedrux ?

Phaedrux

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

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.

Hi @Bloodember, thanks for your patience. Would you like a warranty replacement? The warranty is normally 6 months, but I will make an exception as your Smart Effector may have a manufacturing defect.

Bloodember

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

Please contact filastruder and refer them to this thread as authorization for replacement.

Bloodember

@Phaedrux Ok will do, thank you.

Bloodember

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