E3D Thermistor mod question...
Hello All,
I recently purchased this E3D PT100 Amplifier and Thermistor in hopes to mount it on my MK3.
https://e3d-online.com/pt100-amplifier-board
I'm familiar with Marlin 1.1.4 and I have no problems navigating the firmware and such.
My question is on what line is #define TEMP_SENSOR_0 that you would normally find in the Configuration.h file under thermal settings which doesn't seem to be a thing in FW?
I cannot find it for the life of me and I really need to modify it.
Also I'm not sure how to find out if the Einsy itself supports RTD sensing devices and if id actually need the amplifier?
Thanks,
Tyler
Re: E3D Thermistor mod question...
You just have to uncomment a line in Configuration_prusa.h:
#define E3D_PT100_EXTRUDER_WITH_AMP
Re: E3D Thermistor mod question...
Thanks! Just came to the forum to ask the same question about the firmware.
Here's a link to E3Ds site on the amp.
https://e3d-online.dozuki.com/Wiki/E3D_PT100_Amplifier_Documentation
The E3D site says the only printers/boards compatible without the amp are the UM2 and some duet board configurations.
Re: E3D Thermistor mod question...
Thanks a lot for the responses guys!
@Zinga, After further investigation I cannot locate the Configuration_prusa.h file.
I downloaded the latest Source Code off Github.
https://github.com/prusa3d/Prusa-Firmware/releases/tag/v3.2.1
Am I missing something?
Edited a third time***
Ok, its actually in 1_75mm_mk3-EINSy10a-E3Dv6full.h in the variants folder.
Uncomment #define E3D_PT100_EXTRUDER_WITH_AMP as @Zinga specified above.
Thanks again!
Tyler
Re: E3D Thermistor mod question...
So I just got this and an MK3: https://www.ultibots.com/e3d-v6-pt100-total-upgrade-kit/
Is there a guide somewhere on how to do this with the MK3? I'm familiar with editing code but would rather have a guide so I don't mess up my company's printer. 🙂
Re: E3D Thermistor mod question...
Received my pt100 and amp today. I know it needs GND 5V and signal connections to the EINSY. Other forums just stay to 'connect to P3'
From the board map below (pg 5) the bottom row of EXT P3 is used for the filament sensor, using the top row, I'm assuming I'll just connect the amplifier GND to [7], 5V to [1]. Do I connect the signal wire to the non-GND pin from the thermistor, or should I find a completely different analog input?

This worked for the hardware side, on the firmware all that's necessary is uncommenting the PT100_with_amp line.

So you're up and running with the connections you made above?
Re: E3D Thermistor mod question...
Sorry for the late reply, yes, up and running.
