The problem was I forgot to set up a dummy Tool. Without it the CNC setup doesn’t work. I’ve also got the Endstops working so I’m now good to go.

@zapta, yes that is the correct

@dc42, I thought that would be the answer Unfortunately the board wasn't designed with duet in mind so the options are to run two more wires or replace the pt100 with a normal thermister!

@exerqtor thanks I would be grateful for a picture

The afterburner toolhead pcb has an onboard thermister for sensing the chamber temperature. It has two connections one of which is labelled AGND i.e analogue ground. I am using a duet pt100 board to connect a PT100 sensor one side of which is also connected to the AGND pin.

Is there likely to be a problem if I connect the AGND pin to both the PT100 input and the e0temp ground pin?

@seeul8er I am pleased to say I have found the problem. Basically this is because the Ubuntu version of esptool does not for some reason allow the erase-flash function. I had to download it from the python repository.

So I have again managed to connect to the router. Please could you clarify the format of entry for the printer address. Should it anyway be discovered automatically in the same way as the SSID?

@seeul8er Yes I have tried this but I get a fatal error ESP32 ROM does not support function erase_flash. I am using a ESP32 devkitc v4. Where do you store these parameters?

@seeul8er Thanks. I have now managed to connect the Reppanel to my router and it has been given an ip address. However I seem to be unable to connect to the duet. Further more after several tries at typing in the duet ip address the esp32 seem to go into a loop. I am unable to delete the data I've entered. I have tried reflashing the ESP32 but altho the flashing seems to work the old data persists. Is there anyway to delete the existing data?

@seeul8er I finally had another go with this and have made some progress. I bought a new capacitive screen from buydisplay. Unfortunately I didn't realise it wasn't 3.3v version to start with but it was easy enough to short the JP bridge. I finally managed to get the reppanel to light up. The touch screen seems to work and I managed to find my router. However the one issue I have left is that I am unable to bring up the keyboard from the top right hand corner to change the password. Do you have any idea why this might happen. All the other Icons seem to open OK.

@PCR Any news on the PCB front ?

@seeul8er Thanks for your reply. I had in fact bought the LCD but the resistive touch version. I've been waiting for the capacitive one to come so that I can have another try. Would there be much reprogramming needed to use the resistive touch version?

Hi

I have just started trying to get this to work as I have several applications. I have flashed the software onto an ESP devkit and connected your recommended screen. I have not however connected it to a duet board. I had hoped at least part of the screen would show up but I only get a faint outline in the top left hand corner. I suspect I have made a mistake in connecting to the screen but I would be grateful if you would confirm that is the case. Or does the duet need to be connected.

but it does seem OK with 12V so I'll stick with that until the new one comes.

Further update - changing to 24v causes the sensor to be triggered all the time. I will try 12V if I can find it on the due5 board
