Initial Gcode runs but print doesn't start


#1

Installed a fresh image of Octopi 0.14.0 with Octoprint 1.3.4, did the update. Connected, uploaded a file, hit print. Printer warmed up and did initial homing, but then nothing. Looking at the log, it looks like it's scrolling through the rest of the gcode, but nothing's happening. I see a bunch of NXX lines.

Figured it might be a problem with the gcode, but it prints fine from SD. Figured it might be a plugin, so I turned them all off, but no change. Reimaged and didn't update (left at 0.14) which I know should work, but same thing.

Watched log and it heats and homes OK, but then when it starts code proper I see this:

#2

Hmm, well looking at those messages closely it looks like the gcode might be kind of messed up after all. The M109 commands are not looking right. And yet it printed OK from SD....
Will try to fix the gcode and see if it helps.


#3

Yep, that was it. Had square braces on the temperature commands that should have been curly braces. Not sure why it still printed OK from SD but not from Octoprint. Fixed that and now it works great.


#4

It's hard to tell what gcode will be accepted by any particular printer. There aren't really any standards ATM. We need something like ANSI/ESO 3d printer gcode standard I think.
