Using OctoPrint with Duet

Using OctoPrint with Duet
December 01, 2017 01:25AM
Hi,
I started using OctoPrint with Duet but I am having some problems.
1. M114 command doesn't give E distance. There are E0-E5 values but they are all 0.
2. Pause GCode script is not executed when I paused from OctoPrint interface.

Are there anyone used Duet + OctoPrint?

My understanding is that Octoprint is designed to print files by sending the data over USB from its own SD card. Therefore the pause/resume handling needs to be done by Octoprint itself.

I don't think many people use Duet with Octoprint, because the web interface provided by the Duet provides a lot of information that Octoprint doesn't.

The Duet does return E distances in the M114 command, but not E steps.

Yes, Octoprint is sending gcodes via usb. I know it is not optimal for Duet but I choose to use it to use my Raspberry Pi and touch screen, webcam stream, and some other features. I also think the pause issue shouldn't have anything with the board but my other boards are running ok. Also, I am using a very old version firmware (1.09b-dc42-t3p3-axis-switch (2015-06-22)), maybe it is why I am not getting E values. Duet web interface shows some value for E distance but M114 gives 0

Send: M114
Recv: X:1.00 Y:1.00 Z:84.01 E0:0.0 E1:0.0 E2:0.0 E3:0.0 E4:0.0 E5:0.0

I will try to upgrade my firmware.

I use Octoprint with Duet, and I get E values back:

Send: N38782 M114*33
Recv: X: 0.000 Y: 0.000 Z: 333.841 E0: 64369.1 E1: 0.0 E2: 0.0 E3: 0.0 E4: 0.0 E5: 0.0

It's an old Duet 0.6, with firmware 1.18.1
Octoprint version 1.3.5

I'm using Octoprint for my RADDS running RRFirmware too. There are several buttons in Octoprint, which are strictly "taboo", because they don't work the way they should. ( IIRC extrude/retract and navigation panel ).
I use Octoprint for basic stuff, but with a WIN8.1 tablet PC ( instead of touchscreen ). The tablet offers a lot more options like slicing, checking Gcode Wiki a.s.o.
