I've been planning to build a 3d printer for 9 months right now, unfortunately delayed by surprise medical bills. My original budget was about $1100. As I was perusing the internet though... I came across the M3D Promega printer. I am blown away by the specs, and I'm trying to use the digital dentist guide to evaluating printers and while not perfect, it seems really good for the price. It has duby wbwing - CoreXY Machines
I'm looking at implementing the Flex3drive on a printer. I see on the website that 3mm is the recommended size of filament. Is this a big advantage over 1.75mm filament? I was thinking 1.75mm was the filament size of choice most of the time with the wider availability.by wbwing - General
I'm trying to get a question answered regarding this print surface. My company ha a 3d printer with a 1meter x 1meter print surface. Since the largest size of printbite available is 500mm by 500 mm, I'll need to put on 4 sheets to cover the whole surface. I am worried however that needing multiple sheets will cause issues. Specifically that the four sheets will expand as the bed heats and cause sby wbwing - General
So I'm digging into this design and seeing if I can build it into something useful. Just beautiful work Rectangled. From the comments I'm assuming the OP is no longer working on this project? I'm still really new to 3d printer design, so if you are still open to some questions, it would be a great help to me. I measured the bed to be very large... 600mmx600mm I think. Much larger than my min tarby wbwing - CoreXY Machines
Actually, seeing the results from the D-bot was what inspired me to build my own printer in the first place. I was extremely impressed with the machine and helped me realize that a 3d printer that is actually worth it can be built on a reasonable budget.. That said, whatever I build, I want to push far with exotic materials and functional parts. I'd like it to be as robust as possible with a reasby wbwing - CoreXY Machines
Yes, I was excited by that posting. But I am waiting for more comments on the design . I have no problem investing in all of the components you talked about if the build is sound. I'm primarily worried that the his X and Y axis would flex too much the way he has it. Fully support 1 axis and replace the other with a linear rod perhaps (I figure rods can withstand more force), or just use a very hiby wbwing - CoreXY Machines
I'm certainly no expert, so take what I say with a grain of salt. But here is what I am noticing based on spending time here and my own intuition -Have you considered using a belt and 1 motor to drive your Z-axis? This way they never get out of sync. -The x and y axis. I'm no expert on rails again, I know they are supposed to be a great solution, but should they not be mounted on a more rigid sby wbwing - CoreXY Machines
Yes. It is my money and I definitely want to pick something that will work or can be made to work without too much trouble. I learned a lot from this discussion, but feel like I am at square 1! No obvious way to pick. Every design has serious flaws and fixes are more than just switching out a few parts for more premium ones. Almost feel like saying screw the budget, and just buying this: (hits eby wbwing - CoreXY Machines
There is a BOM. I can source the parts. That's not the hard part. But a guide/support for the build and clearly documented design is what I'm shooting for.by wbwing - CoreXY Machines
Thanks for the feedback both of you. I agree with you Filipe, best to get something higher quality in the first place rather than trying to get a low quality piece to work. However, I want an S-Class, but there are only C-Class (small) printers available. And I don't have the time or skill (yet) to make those printers bigger. I don't care about ABS. But ultimately I want to push the printer toby wbwing - CoreXY Machines
Actually Filipe, I was looking at this one (SmartRapCore XL300). The hardware and printed parts can be bought for $200ish and I could put the rest of the money on upgraded electrical components. Or the whole kit for $550 Do you still think the Voron is superior mechanically (electronics can be upgraded)? It's costing people about $1000 just to source the parts for Voron. So the SmartRapCore giby wbwing - CoreXY Machines
You guys have convinced me. Just pick a printer and jump in. I won't learn by sitting on the sidelines. I'm thinking still pick a diy printer, learn the drawbacks, and try to improve it myself once I understand it. FelipeCampos, lots of great ideas. I'm just not ready to take on a design without a little more direction/support. I think I'll choose between Voron and the SmartRapCore. I'm leaningby wbwing - CoreXY Machines
Thanks for the feedback guys. I read through the C-bot open builds comments yesterday and it seems like getting things square is a bit of a headache for many builders. That seems to be a symptom of the plastic pieces and maybe a sign that problems would continue after the build. Looking through the part files, just getting everything CNCed would blow the budget out of the water. There are a fairby wbwing - CoreXY Machines
Thanks a lot for the feedback Filipe. Yours are good suggestions. And I took a close look at the Eclipse3d. It is a beautiful design. But it's just too small for what I am going for. The last design, again, it is very well done, but I am not at the level yet where I would feel comfortable finishing the design on my own. I really think I need to dig into an existing design and go for the best thatby wbwing - CoreXY Machines
Thanks for the feedback! You're right, I am definitely looking for a CoreXY right now. I like the Eclips3d as well, but again, the bed is just way too small. Do you have an opinion on the smartrap design? Is the foundation solid and the rest upgraded to bring it up to snuff? I'm thinking that I want a 24V system, so I'm wondering if the upgrades required on that unit (new hot end, extruder, electby wbwing - CoreXY Machines
Thanks for the feedback. The smart friendz is an interesting option. But the price is very low. In the words of Mr. Digital Design's instructable, cheap units always have compromises. So I'm trying to figure out if the compromises are in critical components, or if it is all stuff that can be easily fixed and improved on to make a very very solid machine. Any opinions from the experts?by wbwing - CoreXY Machines
Hello all, I've been lurking around and am finally ready (approval from wife) to jump in and build my own 3d printer. This will be my first one, so I want to build an existing design with good documentation before trying to design my own modifications. I'm looking for a consistently quality machine, that prints accurately time after time. I've read the "Son of MegaMax" instructable (thanks forby wbwing - CoreXY Machines
