Re: What's the secret of belts running inside aluminum extrusions - 6 years ago

Archiclem... I built a printer in the design style of a Cetus. Here's the link to the respective forum thread. While I didn't put all the belts inside the extrusions, this might help. If you have any questions just ask.

Re: Cutting Aluminum Extrusion By hand - 6 years ago

I can confirm what DigitalDentist said above - Misumi US cuts extrusion to length which is both convenient and lowers the shipping cost. I order everything this way and it's above quality.

I am 100% interested. PM me for address, etc. If this works well, I might integrate it into a few kits I'm selling. Just checking, the product comes with the LCD and rotary encoder?

Quoteo_lampe QuoteMatthewHall Quoteo_lampe What wrong in that picture? Probably a lot but notably the filament tube bends around the belt. I meant the wires guided through sheer metal. Better use a rubber grommet or some other insulation method. Oh yeah that could be a problem. We figured it'd be ok because it's aluminum and they are fixed tight so hey can't move.

Quotethe_digital_dentist Deets? Yeah I probably should have said some stuff earlier. Basically it's a CoreXY system with a belt driven Z Axis. Uses RAMPS 1.4 and a Full Graphic Display. Goals were extremely sturdy and reliable. I think the sturdy part has been achieved. Entire system is enclosed, as it will stay in the school environment for hopefully a long while after I graduate.

Re: New printer design with new 'twist' for XY on Z - 6 years ago

Quoteklcjr89 Quote691175002 I edited my post with a few more details. The side-loads on a 3d printer might be small, but you are still looking at maybe 200-400g of acceleration depending on the speed and extruder being used. If you put that load on the very end of a 500mm rod that is only being held by a tiny section on one end it will still bend quite a bit. For example here is an extremely r

Re: Beacon 3D Printer - 6 years ago

QuoteArchiclem I already got the motors, belts & some pulleys... So to build the printer i will only need electronic and extrusions and linear rails... Where would you source them? i build a kossel not that long ago using robotdigg stuff (wich is okay, but the whole china sourcing is kind of not that eco-friendly...). For the electronic I was thinking to buy a cohesion mini or another smo

Re: Beacon 3D Printer - 6 years ago

Maybe you could buy a kit Melty but you'd still need to buy the linear rails. You are correct in saying the Aluminum Extrusions are of arbitrary length. The axes are designed to be as independent of each other as possible after the trouble I've had with other designs. It's Friday right now so I'll be printing the final components tomorrow and uploading hopefully Sunday. Being a student is rough.

QuoteMelty QuoteMatthewHall Haha well I'm testing the final models right now. Stuff should be posted in entirety (CAD sources, STL, tutorial) by the weekend. Looks like a nice clean design - looking forward to seeing the rest of it! I'm sure you will have a BOM as part of your build instructions... but what would you estimate the build cost to be? Price should be between 350 and 400 depending o

Re: Beacon 3D Printer - 6 years ago

QuoteArchiclem So as it is close to the first release, How are you gonna handle the position of the electronic and power supply ? Cable management and heated bed ? And, why a Dual Z rail, one would be sufficient ? I think I will build one as soon as it is available P.S. How do you ensure the belt are evenly tensioned ? Electronics will be located under the bed. Glad to see such interest! It

Re: Beacon 3D Printer - 6 years ago

QuoteMechaBits I was wondering how/why you decided to stagger the carriages on Z probably a good choice, more support, easier to fit, better for your 2020, I cant remember why i decided to put mine inline, probably to save on Z height, and probably because I was just thinking linear, straight lines.... , Basically cause they wouldn't fit next to each other on the 2040 rails lol.

Re: HyperCube OverKill Build Log - 6 years ago

I'm starting to appreciate IGUS rails more and more. The standard Hiwin MGN12' and MGN15 rails work fine for me but with bearings and grease and weight they seem so complicated compared to IGUS. I assume IGUS is much quieter?

Re: Beacon 3D Printer - 6 years ago

QuoteArchiclem I really like the cantilever design, If you look for something to stop your head crashing into the bed, I would suggest you to watch closely the Cetus 3d, they realeased a printed part that goes on the Z axe to prevent this...

Re: Beacon 3D Printer - 6 years ago

Quotethe_digital_dentist Your belt arrangement on the X axis is sort of opposite what it needs to be. You've got the bottom half of the belt loop running inside the t-slot, so it is parallel to the X axis guide rail, but the top half of the loop that attaches to the extruder carriage is not parallel to the guide rail. That will result in distorted prints and varying belt tension depending on wh

Re: Beacon 3D Printer - 6 years ago

@FA-MAS the plan is to release all the files with instructions on Thingiverse. I'll update when that happens. @o_lampe the bowden tube is just because that's what I had already @Mecha_bits the belt drive system was preferred over a leadscrew because it's easier to mount accurately. Way easier.

Re: How can i configure Hbot on marlin firmware? - 6 years ago

HBOT works similar to CoreXY if I'm not mistaken. So, open the Marlin config file in the Arduino IDE and Ctrl-F find 'core' or something. If I remember correctly there's a line that allows you to enable CoreXY Kinematics. Do this.

Re: It's Begun - 7 years ago

Quotethe_digital_dentist It's definitely over-built- I don't think you need any of the corner braces or associated hardware, but hey, there's no kill like overkill. Yeah overkill was kind of the plan. We hit the jackpot, all of this material was in the shop already. We haven't bought a single part yet.

So in the Engineering Block Program at my high school my friend and I are building a larger CoreXY printer. Here's the first picture. Like a Tank All I can say is that Aluminum Extrusion is a tank. This frame weighs 30 lbs right now, which is honestly lighter than I expected. Let me know if there's any major problems you see with the design.
