How do you think using just three leadscrews and no smooth rods would work?by MatthewHall - CoreXY Machines
Thanks dalius, how much did the whole z assembly cost?by MatthewHall - CoreXY Machines
QuoteDalius98 I am using three screws connected with a belt (powered by one motor). I've chosen 2mm pitch/lead screws, so I could be using full (or half) steps to move Z and still get reasonable layer heights. I don't think microstepping would be able to provide accurate heights alone... Z speeds are quite low with this setup, but it's not like you need them to be fast... Are you using any lineaby MatthewHall - CoreXY Machines
What is your favorite type of Z arrangement for a Core XY machine? Belts/Screws? Cantilevers? Just need some opinions for my printer build.by MatthewHall - CoreXY Machines
Or you could just use the revolve tool on a sketch in any, I repeat any, CAD system.by MatthewHall - Let's design something! (I've got an idea ...)

Do you mean a cantilever bed? I think a 300mm need would be to big for that... idkby MatthewHall - CoreXY Machines
Hello. Will three lead screws mounted on an aluminum frame be suitable for a core xy z axis? They will be able to rotate freely and will all be driven by one stepper by a belt. Will this be wobbly or will it be strong enough? I am worried that when the bed goes up it will rotate as well if there is not some sort of linear rail on the bed as well. The screws will be mounted on the top and bottom,by MatthewHall - CoreXY Machines
On a more serious note, 4 would work but would only be worth it in huge printers due to the sync that would have to be achieved to reduce belt wiggle and stuff... post it if you make one!by MatthewHall - CoreXY Machines

Do aluminum. I just finished assembling a frame of 2020 Misuimi and it's solid as a rock. I can send you the design if you want, but the printer isn't finished yet. Still waiting for parts.by MatthewHall - CoreXY Machines
Here's a picture of my bed design (just the frame or seat for the bed, I'll use glass or plastic for the print surface) cantilevered bed Any comments? PS: those are MGN 12 linear rails in the foreground. Got them from Aliexpress for $22 a pop! Great quality, surprisingly.by MatthewHall - CoreXY Machines

So I made a cantilevered bed out of wood for an upcoming build. How should I attach the bearings (12mm rods)? Also, will wood be strong enough for a 300mm square bed? I've been building a printer and am on this step now.by MatthewHall - CoreXY Machines

I'm designing a new 3d printer and need some parts printed before I can begin. I am in Ohio and am willing to pay for quality parts. I would like to set the parts up in Cura or the like myself and then send it to you. Resolution isn't so important be strength is key. ABS or PLA should be fine.

Yes, I thought someone might notice that I was suggested by others to ask in these forums for a name.by MatthewHall - CoreXY Machines
I am in the process of designing and building a totally new corexy printer. Check it out in the forum. Ignore the name sated in the previous post (unless you like the name). I now need to come up with a name for my 3d printer, so I came here. Any suggestions? Also, if you can say why you chose the name please do.by MatthewHall - CoreXY Machines
Hi, I'm just wondering if it would be beneficial to tap the 2040 extrusions on the top by the motors. It might avoid the need for larger brackets, as I want to keep the build volume as big as possible. Like this:by MatthewHall - CoreXY Machines
Blender will give you the most satisfying results, though it may take some time. Definitely worth it if you intend to render anything since cycles is a BEAST. Don't even attempt to design engineering parts in it however. For tha go ahead and download Autodesk Inventor Student or Fusion 360.by MatthewHall - 3D Design tools
Sadly, my printer isn't foldable @MKSA, but @the_digital_dentist I will add pictures of CAD files when I get home from school.by MatthewHall - CoreXY Machines
Hey guys. Lately I've been working on a new CoreXY 3d printer. Here is my story of development. My first expo into 3d printing was ordering a Prusa i3 kit from Replikeo in Hong Kong. Not a bad idea, I though...except they are in Hong Kong and I am in Ohio. To far away, especially since their kit was filth and I returned and lost $90. However, that was the best 90 i've spent in my life because nby MatthewHall - CoreXY Machines
Jake- I had the same problem with a cheap prusa I bought from Replikeo. I had troubles all throughout the build and then I plugged ramps into my laptop one day during calibration to keep working. What do you know, my laptop shut off. It turned back on but then when I tried again it did it again. I got smart so I didn't try again but now 2/3 of my USB ports were dead. Dang. At least I stillby MatthewHall - RAMPS Electronics
What is your design like right now? Is it SLA or FFF style? My main bug with the SLA machines is build volume.by MatthewHall - Mechanics
Go with a three point setup, using two smooth rods and one lead screw in the middle. The lead screw won't need to be thicker than 8mm, but depending on your bed size you might want up to 16mm smooth rods and bearings. Whatever you do, don't go less than 10mm unless your bed size is less than 200mm x 200mm. Put all three points in the back, perhaps with the lead screw farther forward.

Hello everyone, My brother and I have started designing a new 3d printer. Our ideas for this project currently are as follows: - 300mm by 300mm by 300mm print volume - 2020 aluminum extrusion frame - printed corners - single extruder (dual to come later) - Y axis moves the X axis, bed moves up and down like H-Bot style. - NOT core xy - under $400 budget. I have a source for printed parts. Anyby MatthewHall - Mechanics
