@AvanSuti Rostock 3D printer. It was the first delta printer. My new delta is a modified Kossel printer. I love my deltas because they are super accurate, fast, and reliable. But all accuracy and reliability is all do to the build quality. If it is was built poorly or not accurate, then like all printers, it would print badly.
@brett_turnage
i found one good looking delta in the uk. https://www.think3dprint3d.com/3D-Printer-Kits/Kossel-Mini-3dPrinter-Kit
it has a E3D V6 hot-end if i understand right whichshould be direct drive one or?
What can u say about this one?
Most delta printers use bowden drives so that the printer only has to move the hot end rather than the added weight of the extruder motor.
The E3D hot end (really all hot ends) can be used either with a direct drive extruder or a bowden extruder. The extruder pushes plastic into the hot end, which is then melted and forced out the nozzle.
To be honest, i consider it quite expensive actually. The cornerparts are just printed and not mold injected. However i’ve red alot good things about the Duet board. But even the extruder is “just” printed. Also it is just a DIY kit. If it would be me, i would stick with an 200€ chinese delta (incl. 2kg of plastic) + 50€chinese 32bit board. But without testing it you can’t tell if it’s a good machine or not. Some specs remain promising, genuine E3d (if it really is) hotend, over 4kg nema 17 motors, kapton heater and many fans. Propably the support MIGHT be great too or at least bether than many chinese sellers.
@Klaus_Daume for the lack of knowledge i find it very difficult to see what’s good and what not. And where i can get update parts and if they will work with the “than” existing printer and so on. I know that a 32bit board is better than a 8 bit board, but idk how they are connected to the printer, will the new one work, is there a software i would need for the board…questions over questions
The printer board, whether it is a single board like the 32 bit Duet board or a shield like the RAMPS board that plugs into an 8 bit Arduino Mega, typically supports 4-5 stepper drivers, at least one hot end, and normally a heated bed.
The biggest issue you will likely encounter switching between 8 bit boards is the type of connectors you plug your stepper motors into. But it is fairly easy to swap the end plugs on the motors and is an issue you will face whenever changing printer boards. Most likely, the biggest hurdle you will encounter going from an 8 bit board to a 32 bit board is having to learn to configure a new peice of firmware.
As for 8 bit being better than 32 bit, that isn’t necessarily true. In most cases, the 32 bit chips will be cheaper then 8 bit chips, should be relatively future proof, and are recommended for Delta based printers. However 8 bit boards are still good for most Cartesian printers.
Quick question is do you have a saw like a bandsaw or even a cutoff wheel? If yes, then just but 20x20 extrusions and you can make a kit.
Ultibots has a kit which is http://www.ultibots.com/kossel-250-v-slot-3d-printer-diy-kit-beta/ for 750. They also sell a metal upgrade corner kit for $70. If you ask them to swap the corners for metal corners then I’m sure you will.
There are a number of 32 bit boards out there. The Azteega x5 v.2 is a good choice, so is the Duet, and BBP. I would myself would spend the extra $60 for a genuine board instead of the Chinese knockoffs just because I know the copper and soldering can take the current of my heaters. All the boards are connected to the printer in the same way. For instance this is the Azteega’s connection diagram. http://files.panucatt.com/datasheets/x5mini_wiring_v2.pdf
Just xyz axes, and extruder, a thermistor to tell the temperature (2 if you Have a heat bed), xyz max endtops, and 12 or 24 watt power. Some boards require 5v as well but that is rare.
@AvanSuti I just looked at the printer. I think it’s an okay deal. Especially because it comes with a duet control board. That’s $125 board. Only downside is that it is a mini kossel and that’s a very small delta. They one I linked to above is about $200 more and it has a much bigger build area.
And don’t worry about not knowing what is good now, that’s where asking people like you are doing in this forum helps–these people know and have experience with either building a machine, dealing with firmware, or working different controller boards.
@brett_turnage i don’t have that kind of tool. The ultibot 750 looks nice and the building area is just the right size. Problem is if i only can get it from the US, shipping and fee’s here in Eu would probably kill it for me.
I posted the bigger kossel (v3)
with 200mm space, v2 has 170mm (they have only this two kits)
Thanks for all the infos, i need to wait till the weekend to have enough time to go through all infos and possibilities.
Were in Austria do you actually live anyway? I live since a couple of years now in Vienna. Pretty sure can make up an hour or two to help you with all your questions, afaic.
@Klaus_Daume i live in Steyr (150-180km from Vienna)
Thanks a lot!
Hah, can barelly be any more far. But yeah, could call or skype anyway.
Build your own!
Use a tried and tested design. Not only will you learn heaps, save yourself a crap load of money, but the final result will most likely be far superior to an “off the shelf” printer of similar value.
