Is this the same kit mentioned here?

it will probably use a revised version of this one:




there are of course some quirks to using a printer in open air, the large bed size, and then dealing with leveling, but hes had some good luck with it so far.

If you are making a bolt on extruder similar to the compact version found on the popular Makerbot Replicator series, you may want to look into this:

How soon until this will be available?

Yes i have seen those. He is from Toronto . One of the engineers that helps with my machines also had some input into that part. They are both R&D engineers for a world wide company . Their makerbot prints amazing. But they have put a lot of work into theirs. But at $100 for one part it would become expensive to complete extruder. Having the Raptor mini and the RaptorX mini that will have profile rails ,Taiwan ballscrews, Proper ballscrew bearings and housings .Proper approved wiring and spindle , machined flat mounting parts. turnkey for same price as china 3040 or 6040 .

I will have them once i have the Raptor mini and the RaptorX mini to make mounting plate for bolt on and off head with out taking spindle off .

[gio666]

The Raptor mini and the RaptorX mini will be made same as all the Raptor machine, everything machined.
Not take a linear bearing house and put 2 holes in it to mount ballnut for ballscrews . Double angular bearings on motor side . Not just a coupling holding ballscrew or some with single radial and not axial support. Machined uprights for bearing to sit where they should be . Not a pieces of aluminum with drilled holes without even countersunk holes. Machined end frames to mounting ballscrew and rail pockets to have rails perfect alignment without touching anything. Not a door hand rail pieces of aluminum with holes in it and call it end frame

I tried to work something with Tekno to get their spindles with out bearings, and use same as china bearings spindles bearings for $0.35. But they decided against it because of liability. But could have sold them 1/3 the price. The money in spindles is the bearings that drive the price high

yeah, each of the setups have trade offs. the wotzbotz V2 addresses most of the quirks. only 2 people have had an issue with the filament running off track on the v1 (out of nearly 100). toby uses a modified spool, and the other person seems to have some alignment problems he solved with a plate on the end of the grear wheel. ours has been running months on end without issue. the trouble is that the rest of the makerbot is so sketchy that even a perfect extruder mechanism is at the mercy of the rest of the machine. youll sell 1000, and 50 people wont be able to use it because the rest of their machine is so messed up (alignment, flex, thermocouple, electronics, etc).

this is why the big players in the game restrict filament use, speeds, resolutions, etc, and of course use much higher quality components.

i think this is why having the xzero cnc frame as a printer is interesting. not as an interchangable device for a router, but just for a base of a new machine. you eliminate alot of the makerbots structural issues up front.

i dont know if its really worth the effort. the teknos are already relatively cheap. all youd end up doing is shortening their life and performance.

There is also enclosures for the small Raptors , one is 12 inch high other is 20

[gio666]

Also with enclosure you could have same temp all the time which makes a big difference in printing

It would save $300 to $400 on some of the spindles. Lower quality is very ecceptable now days. both would look same in pictures, with one almost half the price

This comment epitomizes the compromise of quality for price. It's the reason nothing lasts like it used to. Too bad.

This is true, Problem is most don't know the difference ,as long as it works now.

or the lack of compromise. tekno wouldnt do it after lall.

the bearings george is talking about arent junk. they just cost alot less than whats in the tekno right now. many people use them to good effect on slower speed spindles. at 24000rpm+ though... too many factors come into play.

[Topdecking]

Like quality... He has a point you know.

[ihavenofish]

Like quality... He has a point you know.

um, no. like precision, balance, thermal properties, grease retention.

thats not quality, thats specification.

but again.. tekno refused. so its a testament to a commitement to a high specification, not the other way round.

[SparkCNC]

um, no. like precision, balance, thermal properties, grease retention.

thats not quality, thats specification.

Actually, quality is the ability to reliably meet specification.

The bearing i was going to replace with where quality bearings. MAX 18.000rpm, but would not last if ran hours a day.
Couple hours a week then bearings would last year or two. but when bearings start to go, it takes bearings house with it and will also need to be replaced. But only cost half price to begin with

As this saving money tactic, was pondering idea as lots of the china machines. Cut cost on motors mount , bearing and housing. Which would save a lot of money and just use ridged coupling and use motor to hold ballscrew

you STILL need the bearing and mount when you do that. chinese (and other machines like my sieg kx1) do that when they mount the motor on the floating side. you still MUST have the preloaded fixed support brearing on the other end. this only works with shorts screws as well, and only when the machines and motor mount have 100% perfect alignment.

in short, dont bother, what you have is better.
