Ok, I see what you mean, I am somewhat familiar with g codes just not how the "structure" works in a Duet with the different .g files.

But this will get me started, Thank you!

@alankilian @DIY-O-Sphere

Thank you both, now I got it

-Sorry if this gets double posted, my first try didn't seem to work..

As the title says..

Please see my config file, I have tried a few things that I've red here but none seems to make it more quiet, sorry but can't recall exactly what I did try.

I rebuilt a Monoprice mini with a V6 hotend and fitted an 8*8 leadscrew and runs it with a Mini 5+.
X and Y motors are the original ones and those are really quiet, for the extruder I bought this one: https://www.bondtech.se/product/nema17-pancake-stepper-22mm/
And for my Z: https://www.bondtech.se/product/nema17-pancake-stepper-25mm/

They seem to be very much alike to my ignorant eye and they both make a sound that reminds of the belt-fan in your car when it starts to slip but with a pulsating pitch.

I did try with a motor from the extruder from my Prusa (on my Z axis) and that made it even worse witch I didn't expect since it is quiet like a mouse in my Prusa printer.

Another peculiar thing I noticed when I tried different e-steps for my extruder was that is was totally silent when I used a value of 395, iirc, and with the value of 413, that I need to have, it makes a relatively loud noise.
How can that be?

As you surely can tell I don't have much experience with this so any help and/or suggestions are much appreciated.

@phaedrux
That makes a lot of sense, thank you.
I’m adapting to the wonderful world of RRF and g-codes from more than five years with Marlin

@phaedrux @Torro

Sorry for hijacking the thread
What are the pro and cons of using firmware retractions?

To me it seems a lot easier to use the settings in the slicer so you can have different settings for different materials e.g PLA and TPU, rather than changing your config.g. But maybe I’m missing something?

@paralepsis
Thanks for the pictures. It looks like a fun project.
I will have to test to raise the microstepping and see what happens. The printer I’m playing with is a really cheap one that has a ordinary M5 as Z lead with a (I think) pitch of 0.75mm so it’s less then ideal

@paralepsis said in Rebuilding MakerBot R2X, implications of E steps/mm:

Just to follow up on this, swapping in a 0.9 degree motor was a no brainer and helped things.

Do you have any before and after pictures? That would be very interesting to see.

I am currently thinking of changing to 32x or 64x microstepping as well.

@rkaronde Maybe another silly question but have you tried cleaning your bed? I regularly clean my bed with isopropyl alcohol but once in a while I have to clean it with hot water and washing-up liquid and that can be the difference between night and day sometimes. Even though I never ever touch my bed and it looks squeaky clean there can be some residue on it.

@zapta
I’ll totally agree that it would be an challenge, and as you said; how would you wind them all up and have them synchronized..
You just gave me something to think about for a long time

As for the resin printer, thats on the list but won’t get realized for some time I’m afraid. I just ordered an V-core 3 that I’m looking really forward to build.

@zapta
I only bought 15

@jay_s_uk
Thanks!
I have a big grin on my face now and I will order them straight away

@jay_s_uk
I have my own ideas on what to make and print and put on top of them, but your link gave me a name for what I'm looking for 'Windup walkers' or 'Walker feet'. A quick search on amazon didn't give much but now I have a clue to what to look for.

Thanks,
and if anyone know where to get a hold of these feet please let me know
