Hello,
I am working on a project that really requires that I send data over real serial. Not USB to serial but honest goodness real serial I/O pins.
It appears that there is a serial interface intended for uses with an LCD display. I would like to re purpose that.
If you know what to change to make it so I can send just regular good old fashioned gcode over this interface. No line numbers or checks sums. That would be really great.
Thanks. As soon as I saw that line I commented it out. Testing now.
My firmware version is "2.02(RTOS) (2018-12-24b1)" with a duet 2 wifi
My config-override contains the following.

I have a BossDelta 300 that I need to disable all the heated bed stuff for. The heated bed was removed from the machine.
;M307 H0 B0 ; Heated Bed (H2)
;M305 P0 T100000 B4388 R4700 H30 L0 ; Bed thermistor
In the config.g file I commented out the lines for the heated bed but I still get the following error and the heated bed still shows in the UI with a 2000C temp.
Error: Temperature reading fault on heater 0: unknown temperature sensor channel
My whole config.g file is as follows.
Please help.

Hello,
I have a SeeMeCNC BOSS delta printer and I would like to re orient the machine from its default settings.
I don't want to re wire the machine or mess with the pin configuration. Is there an easy way to rotate the default coordinate system to change what would be considered the front side of the machine? Possibly a single gcode command?
See attached illustration. 
@Veti
I was really hoping to not have to do hardware changes on the base printers we are getting from SeeMeCNC. They come stock with duet wifi boards and we take the machines and add automatic ejection hardware and cloud print management software before reselling the machines.
@bearer using a network connection in my use case would not be practical. The board is being consumed in to a product that the user should not have to do a bunch of janky network set up. The raspberry pi in this use case is intergrated in to the end product and is the sole network connection the user has to set up. The way the system is written gcode is not pushed to the machine from a central server but rather fetched by the raspberry pi and sent line by line to the printer. Shooting the gcode file over to the duet sd is not desired as the raspberry pi is being used to control other parts of the printer directly as the pi and associated extra hardware are designed to be universal and work with a variety of printer control boards.
In my particular use case we are making printers with automatic part ejection systems. It would be too much to ask the user to configure one printer to use 2 different networking tools to make it work. As to pushing the data to the sd card. This is not a viable option. If the usb connection drops out it will not be able to continue print autonomously.
Hello,
I am with Autodrop3d. We have been building 3d printers that use a raspbery pi to send gcode to the control board in a rostock max v4.
Currently use a raspberry pi to send gcode to the printer over USB. The gcode sender program requires an acknowledgement from the board for each line and currently works over the USB. Unfortunately we have some problems with EMI that knocks out the USB interface from time to time. It would be beneficial to allow for changing the default from using USB to using some serial pins. I understand that you can send gcode over the serial interface normally used for the display but the board dose not send acknowledgements.
Pushing the GCODE over a wifi or Ethernet network connection is not an option in my use case.
So right now there is no way to use the displays serial pins in stead of the USB interface with normal response messages.
@dc42 said in Using Panel duet pins as serial interface:
M408
What dose this mean for using the serial pins as the primary interface with "OK" responses from the board. I am in a bit of a jam here and using USB is not an option in my situation. Is this marlin compatibility mode an option? Dose that change the way the firmware works or just the response msgs back on the serial interface?
Thanks
-Mike.
