Solved G-code editing

Do you have experience with tweaking G-code?

I would like to add a few extra lines to the code which I know is easy to do in a word processor, but there is a problem. The code for the length of the filament is continuous. I can't touch the extrusion in a word processor without breaking continuity.

So here is the problem I want to solve:

As you can see in the picture the short parallel lines are printed in the air (picture 1). I want to print a couple of long lines (the red ones in picture 2 ) along the sides before it starts to print the short ones.

Do you know if there is a software that can do that? I mean a G-code editor that will recalculate the length of the filament in every line of code that comes after my editing.

 

Why not just put the lines you want in the model? I would not mess with editing the gcode, lots can go wrong. Which slicer are you using? You could try to rotate the model 45 degrees to see if those 45 degree lines become a continuous straight line across the whole part.

 

I use Matter Slicer, but I got pretty much the same result in Craftware too. Rotating the object is a good idea although in some cases my object is too big to be oriented in any other way. Yes, probably you are right. I should fix it in CAD.

 

So then how are we going to make a good applesauce in the orchard? We have to come down from the apple tree and tweak the ingredients in the pot, don't we?
That leads me back to the original question: Is there a good G-code editor/slicer software out there?
Mattter Slicer can't do it.
Craftware can't do it.
Cura can't do it.
I tried Repetier Host with no luck, despite the fact that it has a G-code editor... somewhat useless, imo.
And there is RapR3D Visual GCode Editor, but it is in its early stage, I think, because I can't make it work.
How about Simplify 3D? Can you edit G-code in it? I keep hearing good things about it, but I haven't decided to bite the bullet, yet.

 

I use HSMXpress for our CNC Mill. It's the free version on HSMWorks, just doesn't have 3D Tool Paths. But they have a pretty nice editor that I use from time to time to look over the code. I dropped a gcode in the NC Editor and it just changes the color of the comments.

I typically don't make any changes unless its a new tool holder with the same size tool or turning off the flood, little things like that. The reason is exactly like @mark tomlinson stated. But I can easily do this with Notepad++ which I am more comfortable with, from building websites. There may be a way/plugin for Notepad++ which will highlight aspects of the gcode. But I have no need for this.

 

For syntax color while editing in Notepad++ there is a plugin:

I've only read about it, I haven't used it yet.

Might be helpful, probably not.

 

Thank you guys, I think I will sign up for a few slicer forums and ask around in those communities as well. I will keep you posted (if I'll find a solution).
