I am a backer and cant wait to put this on my corexy!
flex3drive, dual, (I use 2 hexagons), fully equipped, 2 fans, holders etc .. no hotends is 133g (just measured)perolalars wrote:Yes I know about flex3drive but the nimble is almost half the weight of that.
no clue where additional 15 came from but mine do look a bit different from that one on that web page .. anyhow 28 is still not really close to half .. that's the only issue I had .. as it got me confused ... also comparing nimble and flex I don't see where did they saved on the weight .. the only thing I see is that flex is using quality bearings everywhere (2 for the drive gear, 2 for the gear with hobbed thingy and another one to press on the filament so 5 bearings in total) .. don't see that they differ much in geometry nor size, only if nimble is made from some super light plastic compared to ABS flex is using?perolalars wrote:page its states the weight to 45 grams.
watched the few videos missed the ratio ... I personally like 30:1 more then 40:1 flex uses ('cause I use 400 step motors so I really don't need that much ratio, 10-20:1 would be perfect for me)perolalars wrote: To my knowledge (https://www.youtube.com/watch?v=GNDoCqavWCU at 4.13 in the video) the gear ratio for the nimble is about 30:1. Zesty Tech has done 18 or 19 iterations.... Watch the video
I like em both! I tried flex3drive, didn't try nimble so can't compare them .. just chimed in about "half the weight" ... as for the concept, I hope number of "remote-direct-drive" extruders start "happening" more the merrierperolalars wrote:Anyway, you like Flex3drive and I like the looks of the Nimble and thats ok by me!
