Every time I open up a G-code file and rummage around I learn something new. It is easy to add new lines which will instruct your 3D printer to work in different and better ways!

M109 S185 this was what I needed to fast forward to know how to change my extruder temp to 185 degrees midway through the print after pausing the printer via Cura.

I have just built my first 3D printer and learnt so much already. Thank you for such an informative video.. I'm inspired to edit my own gcode!

Thanks, I was looking for that software. Anyone know if a “pause” command is used, will Anycubic printer continue once the resume button is pressed?

Just what I was looking for. I run CNC mills and just got my first printer and was trying to find where to access the gcode to modify them to my liking.

ok I downloaded the program and I am able to edit the files. So now I ask is Prusa slicer is open source how can I change the gcode that is generated each time I slice a part , so I don't have to manually edit every file every time. I don't like the behaviors of the files when i start printing, it wastes like 10 minutes of time every time I print. Heats up / only to cool down to auto level, then has to heat up again.... wasted movements, etc.. Thank you,

I reckon you can use a Python script to automatically find and edit out the features of the G-Code that you no longer want. Here a intro into that world - programminghistorian.org/en/lessons/working-with-text-files

@ozzytheartist4780 2 жыл бұрын

I would recommend you also show how to edit the GCODE in Prusaslicer. It does let you add cuctom GCODE on any layer very easily, negating the tedious task of sifting through Gcode text to make your customizations and reducing customization errors.

Thanks for pointing that out. I'll definitely dive deeper into Prusaslicer, it really is a phenomenal slicer - particularly in regards to managing different types of 3D printing.

@robertjackson-te8je Жыл бұрын

cura and creality pretend to have this feature however it doesn't appear to work at all.

I have a geeetech A30T (this is a 3 extruder machine) but it seems that the Repetier host always sets it to the first extruder, can you help me to resolve this. I have the software setup for multiple but using the Cura slicer always says it will print with extruder 1

@Core-Electronics 2 жыл бұрын

Hey mate, when you slice the model in Cura have you got it set to have three extruders in the Machine settings for your printer? Otherwise the next step I would try with a sliced file from Prusa Slicer.

Is there a way to know the height of the 3d model by reading the gcode?

@Core-Electronics 2 жыл бұрын

I believe there is a indicator that tells you directly in Repetier-Host, just cannot find it right now. Repetier-Host does tell you the Layer Count and the Quality (Layer Height) so by multiplying those two values you will pretty much get the height of the model that way.

I think 99.999999999999 percent of the people printing these towers are not watching the printer screen and NOT NOTICING that it never changes temperature and that is why their temp tower looks the same from top to bottom. Because that is 100% exactly what I am seeing and trying to fix.

Why dont you dont just do it in cura under Post Processing modify gcode ?

That post-processing plugin section is awesome! Totally a really good way of getting multiple nozzle temperature changes and a whole bunch more as well. And to think I thought I had looked under every stone in Cura, cheers for showing.

@@peters7413 Seeing the syntax would be very useful to those like me that are new to G-Code. That then would make Repetier worthwhile.

How the hell is anyone getting this to work? I have tried and tried and tried with the BS post script processing BS and the MOFO never changes the damn temp it always stays at 225. I looked at the generated Gcode WHAT A MASSIVE JOKE. It never adds anything to change the damn temp. I tried Cura it magically tried to print in the front right corner where only 1/4 of my print would fit. So I switched to it's creality twin which prints in the correct spot but 100% ignores all of the post processing and never adds the damn GCode.

Hey mate, Cura has added support for changing temperature in built. Run through these steps and you'll get your temperature change to work. In Cura up on the menu click Extensions, Post-Processing, Modify G-code. Add a ChangeAtZ script. Specify Trigger for which layer in the slice you want to change temp. Check Change Extruder 1 Temp and type what temp you want. Always add them highest temp at the bottom then lower the temp going up. Then when you slice it again this is added in the gcode.
