Hi guys I wanna show you my last proyect, I call it the Big Berta. Its a huge delta 2m tall xddddd.
I can print 1 meter tall objects and 50cm in diameter.
For exteusion I use @E3D-Online tecnology, e3dV6 + volcano with 1mm nozzle and Titan extruder, and works awesome.
I start the proyect with mks sbase electronics but finally I change to ramps + arduino due to problems with autolevel, and works just great.
Nema 17 and a4988 drivers.
I use my onw profile for the linear rails based in Vslot.
The only problem I got its the heated bed, this piece of glass it’s really dificult to get the temperature within 3 degrees, so I get a lot of zwooble.
Its been a 3 months proyects, with a lot of problems, but finally when it prints, its like oooooh yeah!!!
interesting about the MKS and auto level issues. MKS is based on ramps so what is the problem?
For the glass, replace your glass with C250 or Mic6 cast aluminum tooling plate. Glass is an insulation and metal is better. the upper brands are really flat.
a 0.3mm glas on thick aluminium worked well for me - did you thought about a multi zone aproach? As your bed is not moving - just add mass which will work as a Thermal energy storage (heat capacitor)- a thick copper plate.
The auto-leveling on smoothie works a bit different from other firmware. Run it once, save it and you should be good to go unless, you change the height of the bed or hot-end. The process itself takes a bit of time. It will go around the bed checking different points. I know the base is a clone and not really supported by the smoothie community. But great job, that machine is a beauty.
@Carlos_Porto I tried many times, but I can’t get it working, so finally I change to arduino. Its not going to be so smooth but, in one day the machine was working
I can’t blame you. I’ve gone through a similar frustration withe AZMSZ board, also a smoothie clone. I got everything working now on my delta, but their lack of documentation and community wasn’t worth the dollar savings. Next build going with an official board. Again, great work here. It’s exciting to see giants machines being built.
Very very similar to the printer I’ve been building almost identical build volumes too. Tho, I got mine to work with the mks base board, even the Auto leveling part. Once I get it just right I’d be interested in comparing and contrasting the build cost and materials lists and other fine details.
This gets a little bit expensive, the aluminum plates cost aprox 450 + taxes. For the rest it’s just like a prusa i3. I think everything its aprox 1000 euros, I don’t make the calculations, but aprox @kenneth_rooks
I just see yours @kenneth_rooks . At first I made it like yours, just the same, but 2020 profile made the structure too weak. So finally I add the aluminum plates in the cornes, and that made completly the difference
You’re right @MakerGal , I was troubled by vibrations at first, but my printer is going to be a permanent fixture in my office. So I was able to bolt that bad boy to studs in by wall and I have a significant amount of weight on top of it. I need to post updated photos, but wanna wait till I get the enclosure done.
Again, great work here. It’s exciting to see giants machines being built.
