RepPanel - A DIY alternative to the PanelDue with WiFi support

I_Jedi

@PCR When the PCB is done... sign me up for one! I love the idea of the RepPanel, but have limited skills and time to implement... so the more plug and play the better

PCR

Plan is to put a prototype into production next week! Who would be in?

@pd Try to scroll down for the keyboard. It is hidden on the lower part of the page

@PCR yes please

@PCR I'm in assuming it isn't stupid expensive -- Could I have more details on intended cost and functionality... is this an 'all in one kit'? DIY?

PCR

Would be a pcb only. But you would need a esp and the Display! But would be easy to assemble!

I_Jedi

@PCR why not... I'll give it a go. Looking forward to it! So I should go ahead and order the board and display? Any parameters/features I should be looking for? i assume any ESP devboard should work... but what about the screen?

@PCR I'm in - Subject to costs (+Shipping)

@PCR yes please.

@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

@pd Strange crash. You can delete flash by calling idf.py -p PORT erase_flash

pd

@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?

pd

@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 Sorry if I'm being dense, but I'm not working out how to get the password changed!

I've got v1.1.0 flashed, everything hooked up to the suggested ER-TFTM035-6 screen, it boots and sees available networks, all that good stuff. I'm able to select an appropriate WiFi network. But I need to type a password for that network.

There's a cursor on the line for the password, and asterisks, but I cannot work out how to type in the right password. I have tried using the keyboard icon in the top-right, but that doesn't seem to be the right thing -- that seems to be strictly for sending gcodes?

Sorry for the dumb question, hope it's an easy answer :).

Thanks!

@PCR Yes, interested in the PCB. Thanks!

paralepsis

Nevermind, discovered the scroll. Sorry for the distraction.

seeul8er

@pd The following options are supposed to work for the address:

Auto discovery using the update/scan button
Manual IP entry: XXX.XXX.XXX.XXX
Manual mDNS address entry: XXXXX.local

The prefix http:// or https:// is auto added if not existing. The text field shows .local by default, but there is more in there, the textfield just autoscrolled in that case. Make sure to delete the complete entry before entering your address.

PCR

Display is Here! Works too! Will make a final PCB Design tomorrow!

paralepsis

@PCR Excellent!

PCR

PCB is Ready. Please Upvote this Post so i can see how many i will order!

Price should be about 4 € + Shipping

Then you only need

ESP32 (https://arduino-projekte.info/wemos-lolin32/) This one got the Battery circuit onboard. I added a switch to the PCB if you want to turn off the RepPanel with the Battery
The display.
*2x20 Pin Male Connector ( Thinking about including it)
