G Code Editor in Octoprint - GCode red underlines

Hi All,

Using the GCode section in Octoprint instead of in my cura files. I put the follwing in:

When i started the print it didn't do the nozzle wipe or ABL, So my guess is that it didn't work at all.

I removed all G Code from Slicer too so it literally just started printing. I think there must be somethign wrong with how I enetered the code.

Help would be great

Can you share the complete code you put into the boxes?
I assume there is no heating up the printer.

BTW: these codes really belong into the slicer because this one can select the correct temperatures for the filament you use.

I do not have a start code in OctoPrint, just a short one for the end:

G28 X0  ; home X axis
G1 Y180
M84     ; disable motors
M117 Print finished

Also, I would not home the printer when it's paused. You can't go on with the print after that pause. You may have a look here: https://docs.octoprint.org/en/master/features/gcode_scripts.html

That's great to hear thank you ! You're absolutely right. thinking about it, it might also crush the print?

How does it know which filament i use?

Thanks for your help. I'm new to GCode....evidently :wink:

You are welcome.

Yes, when using G28, the printer goto to zero on all axes. This can result in conflicts with your print.

You select the filament in your slicer: PLA, PETG, ABS etc... these need different temperatures for extrusion and the heat bed.

As I see in this, there are no commands to heat up the nozzle nor the heat bed. So the printer can't print anything.

For more information on gcode you may have a look here: https://reprap.org/wiki/G-code

Appreciate it thank you. It did however do the print just none of the start or end code in octoprint. I ended up with a calibration cube at the end. odd

The red underlines are from your browser's attempts at helping you to spell correctly, I'd guess.

Appreciate it thanks, thought it might be some kind of intellisense.
