Hello everyone, my name is Martin and I’m from Argentina. I’ve been printing since 2013 with my custom RostockMax V1, but it has reached a point where no mechanical upgrade can improve its print quality. So a few days ago I pulled the trigger and bought a DuetWifi. Even though the Rambo board still performs like a champ, it was time for a change and I’ve read nothing but good reviews about this board.

I’m eager to be part of this community as a new DuetWifi user

Right now I’m making test adapters because I don’t want to remove the existing Rambo connectors.
Below the board sits a 90mm fan, which may seem too overkill, but it’s also for cooling the entire electronic compartment (psu, step-down, motors).

The board came with these connectors. I get where the white ones should go, but what are these bootlace ferrules for?
If had to guess, from left to right: Power Supply Input / Bed Output / Hotend Heaters ? Please correct me if wrong.

There was another bag with housings. I think these ones are for the Panel Due.
Which one/s do I need to use? I was just going to connect it by using the first one, but there is a 8 pin Dupont and a 4 pin one.

Please advise.

I've a 0.4mm nozzle and a 0.25mm spare that only used once. I've been printing since 2013 and never found an excuse to install the smaller one.

I think that the 0.4mm nozzle has the perfect speed-resolution ratio.

EDIT: typo

Oh… I took too long.
David beat me

Because of step unit error. With a 15 tooth pulley, 16 microstepping and 1.8º motor your steps per mm would be of 106.666¨ instead of just 100 with a 16 tooth pulley.

Check out this article, it's well explained and interesting reading:

Hi, as for what you should measure, this pic might help you:

I don't think you actually need to measure it, those values should be inside Marlin's config or whaterver firmware the Anycubic has.

And how about the bowden path? If you feed it by hand, do you find any resistance?
I once had a filament that was just a bit thicker and it got stuck inside the bowden tube.

Maybe you are trying to move them too fast?
David provided a spreadsheet to work out the speed at which torque starts to drop off:

You are right. I got confused, sorry.
I'm going to bed now

@Martin_S:

Hello, M350 needs to be set before M92.

not really, if you use M92 before M350, the firmware assumes 16x microstepping for M92.

Uhhm, yes, but he is using x32 miscrostepping.
