G-Code 5 axis sample code

JoergS5 · 6 Feb 2023, 07:09

I try to finish the CoreXY 5 axis prototype to test RobotType kinematics, but I don' have a G-Code file to test it. The software which exists is expensive or needs time to invest for setup. And when I created the code, I'm still not sure whether an error is due to the created code, the created printer or the created firmware.

Is it possible to gather samples of license free 5 axis G-Code and make a repository for testing? Can you provide a sample please, which is proved to be error-free?

I would prefer if the Duet team stores it in the Duet realm, but I can create a github on my own site if necessary.

I know that G-Code is machine specific, but if standardizing on a few common properties like 0.4 nozzle, it should be possible a G-Code where maybe only the header will need modifification.

The samples could be categorized by

small objects, big objects
for AC or for BC
nice looking or for calibration purpose
later there can be more categories, like multitool with toolchanger

Something like a Benchy, but with difference between left and right, so object mirroring can be deteced.

@JoergS5 It's probably the wrong forum to ask for any 5 axis gcode, since RRF doesn't support it yet.
The only guy I know, using Duet boards on his 5 axis Prusa build uses grasshoper slicer on Rhino3D. Maybe you can ask him on his own homepage?

@o_lampe Thank you, I know Freddie Hong. Rhino is not free, unfortunatley it's 1000 $ for me (I am no student and not commercial => bad combination here).

You may be right, I'll make the firmware without code. I hope I get it correctly.

You'll be pleased by my CoreXY prototype You'll understand why when I post the images.

@JoergS5 It's a hen & egg problem obviously. Lucky for you, there is a guy already waiting for your code to test it.
Quite different to the multi-gcode feature of RRF3.5. I expected to already see some reports of running machines, but it takes surprisingly long time for the 'guinea pig' hens to lay an egg

@o_lampe I second every of your words. I review yesterday some of my old posts and prototype builds and I was a bit shocked how long it takes. The only excuses I
have is that there was a lot to learn and a "private issue".

It's a shame that school didn't prepare me to complex numbers and e.

In school they told us that it's not possible to take the square root of -1, ten years later they showed me the workaround...

At least you didn't run in circles, but progressed from DH parameters to screw parameters.

that's a good yoke! I didn't run in circles, I run in screws

@JoergS5 like Fibonacci (which I didn'nt have in school also)

@JoergS5 take a look at https://fullcontrolgcode.com/. It can generate 5- axis code.

thanks a lot David to tell me! I know FullControl from the Excel version, it is a great program (I don't have Excel however). I missed the news that it is Python now. I'll try it for 5 axis.

@JoergS5 I'm not sure whether the standard version can generate 5-axis GCode or whether that is a different version. User @brendon would be able to tell you.

@dc42 there is some information about "FullControlXYZ 5-axis pipe design tool" which offers the required functionality. I'll try it when I finished the prototype.

A link is eg here:
https://fullcontrol.xyz/#/models/duet22
(Edit: this links cannot produced code. But I saw samples on Twitter and LInkedin. Should function).
