There is no FW for JR currently - did you read the readme ? https://github.com/luc-github/Repetier-Firmware-0.92/issues/106
there are some work on going but not using arduino and not based on repetier FW and currently not workable
This the FW on which Im working. but after installation, usb port gets disabled.
and this the wifi FW which I think is compatible with Jr. help pls what to do?
to flash Jr with duet FW you need to use samba as currently I did not finished to work on bossac for sam4e (https://github.com/luc-github/BOSSA/tree/arduino)
I use 2.16
the process is described here and it works for me
be aware duet FW is absolutly not compatible with JR - only the core but not the pinout and I am 99% sure the variant need to be modified as I was not able to find the heater pin neither thermistor pin
Did you worked on jr pinout ?
What do you mean by only the core? and yes i have pinout list and have tried it also. but dont know where Im lacking knowledge. and yes it is variant.cpp If I give you pinout list can you share me the modified variant.cpp?
pinout list attched here.
this is not the pinout just the pin definition from MCU point of view
here the current know pinout that I have shared : http://www.soliforum.com/post/131637/#p131637 we have end stop / light / motors pins still miss heater pin, thermistor pin, sdcard reader pins, lcd pins, filament sensor pin, Jam sensor pin, others TBD ?
also duetFW does not support lcd / keypad so need to add it once pins are found
also be aware that after erasing FW - the extruder is heating without control as soon as printer is power on so better to disconnect it when doing your tests I connected a 12v fan instead on my JR to monitor the activity
ok thank you for your support. Can you please share me the duet .bin file with details procedure which you have modified to use in SAMBA 2.1?
and meanwhile I will see the pinouts for heater and thermistor. btw my extruder not heating!
also, please share modified variant.cpp on my email. prahalad.solanki.90@gmail.com
it will be a great help. thank you
Sorry I have nothing to share as I did not modified the vaiant yet - I am currently working with existing variant I did not modified the duet FW for JR, I did some test FW to test find / the pins but nothing for the printer itself
if you can find pin for extruder and thermistor would be great I am currently busy with another project but will come back to JR porting soon
any update ?
I close issue then - feel free to reopen if needed
I have one of these on loan to "fix" for a friend. Whats the best way to get the pinouts for you?
Actually the pinout is now known - (http://www.soliforum.com/topic/13769/davinci-jr-repetier-port/page/6/) the reason why thermistor / heater what not detected was because they are handled by another mcu which make porting even more complex as there are 2 solutions : 1 - hardware rework to re route the pins to main MCU - not easy for most of people 2 - reprogram the MCU in charge of temperature - LPC1115 is an NXP mcu - ideal case would be to be able to flash LPC1115 using the main mcu - not sure it is possible, another solution whould be to use the header to flash it but this need soldering - and this one it is not easy
So it become harder to hack but yet not impossible
I have tried using ATSAM-BA 2.1 for installing custom firmware but after upload board not detected. if anyone has binary file of firmware please share
