GET3D free give away free extruder.
-
I just did the forum so people could help each other if they buy the extruders.
-
Today I received a parcel in the post containing a Get3D extruder.
I've had a quick look over it but I don't want to pass judgement on it too soon.
In the meantime, I wanted to share some more detailed photos. I was sent the high temperature direct version, which is fitted with a 100w 24v heater cartridge and a 'K' type thermocouple.
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
-
100 watts! Uncontrolled, that could get over 800C!
-
Looks like a nice setup ! ... and yes, a bit scary at 100W
-
Not impressed.

why ?
Well for one it looks like a prototype, not a quality production unit.
And I would prefer a unit that took up vertical space instead of horizontal space.
All of the printers I have built had a surplus of vertical space compared to horizontal space.

Good point about vertical vs horizontal space requirements but the bit about a prototype (which it likely is since it was just released) seems a bit harsh.

It's a "production unit" since it was shipped to a customer unless the customer knew he was getting a prototype, which he doesn't say in his post.

Since it was a freebee, I don't think the strict thinking you are applying is entirely fair. I still think that other than the fan mounting plate, it is a very nice looking unit be it production or prototype. My only concern would be being locked into one supplier for spares which tends to get expensive quickly.

You may be right but if I was trying to gain customers the first units I shipped for free would be the best I could produce.
The issue about suppliers is a important one. I recently decided to try a Mosquito based on some research. It was pricey to be sure and who knows about the viability of the supplier. But it certainly is a first rate design and I am very pleased.

This is not a new design, it's a micron which have been around for a few years.
I have one at work but with a more powerful hotend. The machining work is excellent and it performs well overall. I do prefer a dual drive like bondtech so I don't use it much.
My only complaints are that wire management was obviously an afterthought and that the motor gets excessively hot during use unless I derate the amps quite a bit.

So the one being offered for free is a copy of another companies work?

Printers: A FT-5 with the 713 upgrade bits, a custom MarkForged style, a small Utilmaker style, a small CoreXY from kit and a E3D MS/TC setup. Various hotends. Using Duets (2 and 3) running 3.4.6

Hot damn! It is a sexy looking gadget. Let us know how it works?! As for power, we got lots power! Braided wires, built-in extruder, hi-temp hot-end...and small too..and some mass...
It is sexy.

@fcwilt More likely they're just distributing it under a different name. The original is made in Israel.

Hi everyone,
I have new 13:1 gear motor for 65.00 each They are great for z belt drive.
-
@Get3D Planetary gearboxes are usually not whole number ratios. What's the actual ratio?
What sort of full steps/mm will you end up with in a Z axis application?
-
Seems to me that 13:1 is way too high a ratio to be useful for anything 3D printer related <shrug>
-
@jens55 In the Z axis it's fine. I have 30:1 in the belt lifted Z axis of my printer, using a worm gear so the bed won't drop when the Z motor loses power.
13:1 may or may not be a high enough ratio to prevent bed drop. It will depend on the weight of the bed, friction, and the motor detent torque.
Planetary gear boxes don't usually have whole number ratios. That means that you probably won't be able to get nice, round whole-step movement values from the Z axis. You'll end up with a weird value like 158 um/whole step. It doesn't really matter - it will print fine, but the weird number can make it a little troublesome to calculate the number of layers in a given thickness of plastic. It's just a number, but that sort of stuff bothers me.
