GCODE Scripts for OctoPrint and the UM2+?

Recommended Posts

Hi,

My relation to OctoPrint seems to reflect the shape of a sine wave - I get to it, encounter a problem, forget about it and get back to it several releases later until the next problem occurs :)

This time I'd like to use it with the UM2+ and have the following scenario:

I'd like to use the gcode start scripts in OctoPrint:

The problem is - these scripts are wrapped around the gcode that is produced in Cura. So if one tries to emulate the start-up sequence of the UM2 in those OctoPrint gcode scripts, it fails because there is no M104/M109 heat-up command. The solution would be to ditch the OctoPrint gcode scripts and use the standard Cura start/end gcode scripts.

So my question is - does anyone use these OctoPrint gcode scripts for the startup sequence? If so - how?

I've posted a question on OctoPrint g+ here:

UltiGCode uses volumetric e-values, i assume, that you have changed the GCode-Flavor in Cura to "Reprap/Marlin", right?

The remaining problem is, that Octoprint has (obviously) no clue about the temperatures that you have defined in Cura (as Mark Walker said: this part is executed after the start script from Octoprint).

You can add values for M109 and M190 to your Octoprint script, but only with fixed values that you have to change for different materials.

As an alternative: you can (pre-) heat buildplate and nozzle manually with Octoprint before you start the print.

But that's sooo inconvenient..., and i'm still not sure about your intention...?

It's so much easier to use the start/end-code from within the slicer.

Yes I did set to regular Reprap/Marlin.

And you are right - manually heating up defeats the purpose of having a remote device taking care of the print. If I resort to that I could as well walk up to the printer and start the print from the sd card.

Maybe I'll do something in between. Like set a fixed value in OctoPrint and let the gcode heatup value override it when the print begins. It will only break when the difference between my fixed temp and the gcode temp differ greatly, but ok, you can't have it all :)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
