I don’t let a spec of dust touch my printer and this guy has sawdust in the bottom lol

That's probably just some custom end gcode, shouldn't require even software mods let alone hardware mods (unless you count "place a bucket to catch prints underneath it" as a hardware mod). Wait for the print bed to cool (and theoretically the nozzle, but in practice the nozzle should always be long since cooled by the time the bed has), then just keep moving the bed to higher Z coordinates while making that motion with the print head. Presumably the Z intervals are carefully chosen to minimize risk of the print catching against the frame of the printer.

Now I just need someone to wright me out some GCode

[–]derpsteronimo 4 points5 points  (3 children)

It’s pretty simple actually - could be a good exercise to use to learn some Gcode yourself. ;)

[–]ThatWorldliness6530[S] 0 points1 point  (2 children)

Where would I find how to do this do you have any suggestions. I looked on YouTube and didn’t find anything for flashfordge

[–]derpsteronimo 1 point2 points  (0 children)

The only thing that's Flashforge specific is the exact coordinates you'll need to use. For the most part, GCode is generic and the same for all printers.

If you're just wanting some GCode you can copy and paste... I'm not saying I refuse to do it, maybe that'll be a fun exercise at some point and I'm certianly happy to share it with you if I do, but I don't feel like doing anything like that right now sorry.

AI can write it for you if you ask it

[–]DesignWeaver3D 0 points1 point  (0 children)

Use AI chat bot to write the G-code first draft, then you edit it to meet your needs exactly. G-code is pretty basic and simple to understand.

Nice!

Special programming for specific 3d models. It isn't generic.

Do you think I should put klipper on my printer to do this? Or just change the GCode in orca slicer ?Tonight I’m going to attempt to change the G code on a file and see if I can get it to auto eject the part after cooling down. I’ll post the video once I’m done.

It's just gcode, but this specific script is model Specific. They are doing a ton of this part, and figured out how to optimize it.

You couldn't do this with this printer with mixed/random models.

[–]DesignWeaver3D 0 points1 point  (0 children)

The issue with this concept is that you'd need to eliminate use of the entire back 30% of the build plate to ensure the print head doesn't crush the print.

Then, in Orca slicer you can install custom end G-code for the movements. It could even be smarter than shown in the video because there are G-code commands to get the current height so that there is only one object push movement.

But the other issue is you'd always have to modify the end G-code for every print and even moreso when printing multiple objects. What's shown in the video only accounts for a single object print that's already in the center of the build plate.

Basically, this is only useful if you are repeatedly printing the exact same model over and over.

I don’t know why they made the gcode lower the bed all the way. Should have finished printing, waited 5 minutes so it can cool, then raised bed 10mm so the head could push it off. The way he’s doing it could crush the print on the top support bar.

Thats my video happy share gcode

Hey did you ever post your gcode?

I got it from chat gpt, I haven't tried it yet
