Mk2s to Mk3s upgrade questions
I have a Prusa i3 mk2s made as cheaply as possible (see picture)
The printer is running modded firmware to compensate for a smaller bed
I'm wondering what it would take to upgrade this to an i3 for a dual drive extruder
I would like to know what parts that I would have to print
sorry if I posted this to the wrong area as I am new to these forums
thanks
Best Answer by bobstro:
What I mean is to have two drive gears in the extruder instead of a drive gear and a bearing.
Ah, OK. I usually see that referred to as a "geared" or "dual-geared extruder". I thought you meant something with dual motors.
The (discontinued) Mk2/s to Mk2.5S upgrade kit mentions a Bondtech upgrade, so you might look into those parts. @joantabb is our resident legacy Prusa expert. She might know more.
It might be easier to adapt something like a BMG, aero, or another extruder that is more modular.

This might help:

I could not find a better resource.

Not the right forum to ask on.
Your best idea is to go to a general 3D printing forum such as reddit or facebook. This forum is for users of Official Prusa Research made printers not clones. While the users on here might be able to give general advice it is unlikely people will be able to help with upgrading clones and this forum is not the place to discuss this.
Do you mean dual nozzle?
[...] I'm wondering what it would take to upgrade this to an i3 for a dual drive extruder
Sorry, what do you mean by "dual drive extruder"? Do you mean a 2 in-1 out extruder or 2-in 2-out dual hotend setup? If so, none of the official Prusa printers are offered in this configuration, so you are likely going to have to find a design elsewhere to do so.

bondtech
So like a Bondtech?

Mk2/s to Mk2.5S included the upgraded bondtech extruder gears
