Hi,

 

need some help here.

 

I'm running an orangepiwin:

 

root@orangepiwin:~# uname -a
Linux orangepiwin 3.10.107-pine64 #11 SMP PREEMPT Sun Feb 11 19:22:44 CET 2018 aarch64 aarch64 aarch64 GNU/Linux

 

I try to use it for my 3d printers, by using a thing like octoprint or repetier server. I woud prefer repetier as due to its smaller footprint.

 

I have issues to etsablish usb communication - it works fine on raspbrian on an rasppi3, so I guess the printer(s) are fine. I think this is related to the USB communication, I can see that the printer is detected. 

 

root@orangepiwin:~# ls -la /dev/ttyU*
crw-rw---- 1 root dialout 188, 0 Aug  6 07:32 /dev/ttyUSB0

 

I can also connect from repetier server and can see the output of the console about marlin fw. However I can not move the axis in any direction or home the printer with G28. Seems I can not talk to the printer from armbian.

 

I also tried this:

 

usermod -a -G dialout repetierserver

 

No effect - I uploaded armbianmonitor -u here http://ix.io/1jiP
 

Somebody have any idea what I can try next?

 

Thanks!

 

Regards

Joerg

... maybe thats the reason?

Sorry... that seems to be related to i2c... 

Issue can be closed... work now. It was - shame on me - the long USB cable.

 

I did not looked at it as it works perfectly under Windows. I switched to a short one... works!
