G-Code for OctoPrint before print  

RE: G-Code for OctoPrint before print

Does anyone want to share they G-CODE before print starts for OctoPrint?

I am looking to preheat the bed and nozzle for a few minutes -

Does anyone have a "PRINT" file Gcode which I can simply print to preheat the unit?

 

Thanks

 

 

I have made a short warm-up gcode, which you can of course change or adapt for your purposes.

M104 S170; set extruder temp for bed leveling
M140 S60; set bed temp
M109 R170; wait for bed leveling temp
M190 S60; wait for bed temp

G4 P1000 ; wait 1000 msec

G4 S100; wait 100 sec

What is the purpose of moving the bed diagonally so many times?

I always used to warm up our CNC machines in the workshop (including axis movements) so that everything would come up to operating temperature (motors, spindles, bearings). Then I started the machining process.
As I said, this probably doesn't have to be the case with the printer, but I think it can't be bad if all the components are at operating temperature.

But everybody should decide that for himself.

It's an interesting idea. Moving the nozzle around to extremes before a print is also a good way to check for obvious things like snagged cables or items moving into the print path. I like the idea of doing that on the first print of the day, or when the bed is room temperature perhaps. I don't think that can be done in the slicer, but it's an idea for an OctoPrint startup script. Doing it as the nozzle warms up wouldn't add much time to the overall startup time either.

Since I print a lot of nylon, warming up the entire system (including drying the filament) before starting to print has always proved to be a good idea. But of course not everyone prints nylon.
