GET3D free give away free extruder.

Constant reaistance to movement due to detent torque and gearing down is far easier to conrrol than constant friction. I've done belt z with no gear reduction and 4:1 and both drop with no power. Belt and worm is the next major mod for my P3Steels following on from 1mm pitch trapezoidal screw.

They are 5:1 same as the ones on the lulzbot. I only have very low stock right now but I can get more very soon.

(5+2/11):1 According to your data sheet.

This is a funny number, equivalent to a 57:1 gear followed by 1:11 gear. I wonder if those two numbers are intuitively visible when looking at that gear's internals.
As for bed dropping, my 310x310x6mm bed holds well with these anti backlash nuts https://www.aliexpress.com/item/32838135064.html (two 8mm lead screws, 4 starts, 8mm lead).
Edit: Not applicable for belt drives though.

The high gear ratio motor is mainly being discussed in relation to a belted bed, no lead screw.

I just want to let everyone know i dropper the price to 80.00 each. They are very nice extruders and work great. I gave 10 away and no one has replied at all. I hope the ones I sent out for free would let everyone know how good they are there was a lot of work put in to them. I hope to her back from the people I sent them to so we can see how they like them.
Thank you

@Get3D Yeah you need someone to actually write a review, it does seem like a lot of mass for me to be honest.
-
You would be surprised. I want so to write a review because I could put anything. So I would love some else to do it.
-
Maybe consider making your expectations clear from the get go in the future, helps reduce disappointment.
That said hopefully someone will feel the calling to do a write-up. Or reach out to some of the bigger names on YouTube to do a review perhaps. If you got say Alex Kenis to do a review I'm sure it would get all the praise it deserves.

@jay_s_uk got a free one, the only forum user that said he got one. How is it, Jay?

@droftarts
I've only just got around to designing a mount for it.
My toolchanger has taken a little longer than I expected to get up and running.
That being said, I'm free of the family for a few days in a couple of weeks so I intend to get it all fitted and tested then. -
Hi jay_s_uk,
I can't wait to see what you can do with it. I hope to see it soon.
