Macro's - Repository?

tsitalon1

Do we have a macro repository anywhere on this site?

I apologize if I missed the obvious, but I cannot seem to find one.

Phaedrux

Not that I know of, but we could start one.

I think that it would be awesome if we could collate macros that people find useful.

I think it would be best to use github and link to the repository from the documentation.

I prefer not to link them directly from drop box as they is not permanent.

I have created the skeleton of a documentation page here:
https://duet3d.dozuki.com/Wiki/Macros

@Phaedrux thanks for sharing the drop box directory of all your macros. I have used you pressure advance macros as an example. Do you you mind if I copy your drop box onto github?

T3P3Tony

@phaedrux I have added your pressure advance examples to the github repository. Do you mind if I add the other ones?

Repository is here:
https://github.com/T3P3/GcodeMacros

@t3p3tony This is a fantastic idea! I'm building my second Duet-powered printer now (a RailCore II 300ZL) and I've seen some of the other builders have created some terrifically useful macros.

Phaedrux

@t3p3tony I don't mind at all. Share and share alike.

Awesome guys, thanks for adding this!

It'll help out the Duet newbies like me, hopefully I'll be able to contribute shortly.

T3P3Tony

@phaedrux Thanks - I have added them.

Looking forward to seeing some more.

I LOVE THIS!

I cant believe no one thought of this earlier.
I know for myself, I sometimes get confused because there are so many ways to use a duet and I can't find an example for say a Cartesian vs a delta. The duet team does such a good job with documentation but it is an impossible task for a small team to give so many examples. (now that i own 3 duets im a little better).

I imagine this will be another invaluable resource. Especially for people just starting out.

T3P3Tony

So I have added some macros provided by @deckingman

It would be good to get some more off people, then i will have another look at the documentation page and slot in examples and links.

@t3p3tony

I did actually start a thread way back in May 2017 https://forum.duet3d.com/topic/162/macros-ideas-suggestions-tips-and-tricks to try and get people to submit ideas.

There wasn't all that much feedback but you might find a couple more there.

T3P3Tony

@deckingman thanks, I will take a look

If I knew how to use github i would add these directly...

I did not write the first one, someone on the old forum did. ~~Sorry stranger for not writing down your name~~.
[EDIT: @dc42 and @burtoogle are responsible for this macro]

The second one is a simple probe repeatability test with moves between.

These aren't rocket science but have helped me.

@alex-cr The non-linear extrusion test is interesting, but how do you use the results? Non-linear extrusion is on my list to explore next.

T3P3Tony

@alex-cr Thanks. I have added them to the repository.

@phaedrux said in Macro's - Repository?:

@alex-cr The non-linear extrusion test is interesting, but how do you use the results? Non-linear extrusion is on my list to explore next.

The intent is to measure the length of the extruded sections to ensure they all come out the same length, regardless of extrusion speed.

I need to add to the macro to supply rectraction because of my 1.2m bowden tubes on my main printer now so in reality I have not used the macro very much.
I really wish I could find the forum post to reference...

fma

But how do you fit the measured values, to get A and B params?

Alex.cr

I found the link! Turns out it was @dc42 and @burtoogle that wrote the macro. Thanks guys!
https://forum.duet3d.com/topic/3625/new-beta-firmware-1-20-1rc2-and-duetwifiserver-1-20-1/14

@fma Set A=0.015 and B=0.0012 and start there. At least that's what I did. Extrusion was more consistent at higher speeds. These numbers worked on my direct drive system at the time.

I was not very scientific with it, it just helped so I left it there. That's what @dc42 had come up with on his setup.

I need to look into this again but since upgrading to a bondtech extruder the problem hasn't resurfaced.

fma

I'll try these values, but I would like to know how to compute them from a set of measures...

Alex.cr

@fma This involves solving for a nonlinear equation. A recent posting shows sort of how to do it.

https://forum.duet3d.com/topic/5588/non-linear-extrusion

I have build an excel form to create a best fit equation, this may help you.
The values in the form are bogus, do not use those... enter your own.
