I have tried the tutorial to no avail.
Wiring is the same as the diagram in the tutorial.
I will double check wiring specific when I get back to the nextion and look and double check the TX and RX. That is very good advice.
Still only get connecting to printer.
Also, I am trying to keep one for nextion and one for marlin. Sorry for doing so but you guys both seem like experts in the respective topics!
]]>Barring that, is your wiring correct? Step 6?
Remember that TX on one device needs to go to RX on the other device.
Also, please consider starting and maintaining 1 thread for overall help. Your other thread and this are overlapping, and if you are unclear about some things, you will get confused by the multiple efforts to help you. .
]]>I am still stuck on getting the nextion to go with my nanodlp. Included below is a command that I was instructed to use for helping troubleshoot. I recently also enabled i2c arm connections.
pi@raspberrypi:~ $ dmesg | grep tty
[ 0.000910] console [tty0] enabled
[ 0.794571] 3f201000.serial: ttyAMA0 at MMIO 0x3f201000 (irq = 81, base_baud = 0) is a PL011 rev2
[ 5.834550] systemd[1]: Created slice system-getty.slice.
[ 7.816217] usb 1-1.3: FTDI USB Serial Device converter now attached to ttyUSB0
Thanks for your help
]]>1. did you wipe the card and do a fresh install?
2. did you do the sudo raspi-config steps shown in the guide i linked?
3. after you enable and set up netowrking, ic2 and ssh do a updage and upgrade
then make sure you can ssh to the pi via bitvise or putty
EDIT: you school probably has a Linux user group, you might want to get help there to get the raspi connected. once you do that, then we can help you get going with nanoDLP. I am not trying to brush you off, but campus LAN might best be handled with local folks instead of some random internet people.
]]>But the error that is coming through states that "changing ownership of '/etc/dhcpcd.conf': Operation not permitted
dpkg: error processing package dhcpcd5 (--configure):" so it might be a wifi issue and since I am on school internet via Ethernet I could not figure this out.
Thanks
]]>if you are online now, you can jump over to the Fb site too -
https://www.facebook.com/groups/nanodlp/
might be easier to chat there
]]>Thanks
]]>this one is the most current info https://www.nanodlp.com/forum/viewtopic.php?id=2069
my advice- wipe the card and reflash the distro and add the files.
]]>I am currently working on a custom 3D printer for my university and I am having trouble getting my 2.4" nextion hmi display to go past the "connecting printer..." screen. I tried both nanodlp.tft file and tibus.tft file and neither got me past the screen.
I followed the tutorial and steps on page 7 on the forum title "Touch screen for NanoDLP" and I still got nothing.
I think I am missing a step on the NanoSupport Setup page but as you can see on the old forum it has been updated since 2018. I think I am going wrong because I do not know where to input my nextion port address.
Thank you all for your help!
