Question 2nd Motor to mirror extruder motor motions?

[Laserbea4k43]

How hard would it be to write a script to allow a 2nd (bowden) extruder to mirror my main (stealthburner) extruder's movements at the same time?
Could I simply follow this?

Yes, do it like the documentation or if you have a 2.4 look at the Z motors, they work together.

Makes sense! I'll have a look. Thanks!

Several boards also have a dual output channel that allows you to two motors in parallel off of one driver. Not sure if you would ever need to run them independently, but if not, that may be a quick and easy solution. (I know that the Octopus boards definitely have this!)

Oh crap! I've been planning to get started on this project today, as I'm finishing my 2.4V2 conversion(x rail) and TAP install!
Definitely looking into this! Thanks!

Hey Laser, I am curious what you are trying to accomplish? CW1 and CW2 have a lot of push/pull force.
I run a 4KG or 9LB spool on the back on my V2 with no problems.

just need a little something to assist with getting TPU through the tube, since I'm not really keen on building a top-loading spool holder to warp my extrusions.
I thought about putting together a top-loader that stands itself up by the left and right bars on the top, but....nah

I see.
I had a printer dedicated to TPU but I didn't use it for a couple years so I got rid of it.

If you do get the duel motors setup, post some pics, would love to see it.

Sure. just need to take more time to figure out how the mirrored drivers connections work as @Dave mentioned.
Hopefully this weekend.
