QuoteDust ah Misumi, the company that wont sell to individuals unless your an American... So sadly useless! but nice to know. But if you are in America Misumi is the greatest thing to ever happen to anyone ever. Literally can order extrusions of any size, color, slot, etc. and cut down to half a millimeter.by MatthewHall - Extruded Aluminum Frames
What electronics package is that? Nice job, BTW!by MatthewHall - CoreXY Machines
If it breaks again, throw it out. Get a Smoothieboard or Duet.by MatthewHall - CoreXY Machines
Less parts. Coming from someone who has designed and sourced his own custom printer, shipping is a bitch. Take this with more than a grain of salt.by MatthewHall - General New Machines Topics
FYI Heads up and Whatever, but a lot of your pictures don't load. Would love to see it though!by MatthewHall - CoreXY Machines
Pugzor, 750mm will almost surely be to long for smooth rods and bearings. If you're worried about price, I would suggest looking on Aliexpress. I bought MGN12 rails for my CoreXY build and it trned out to be cheaper than a comparable smooth rod setup. IMO the way they bolt onto the extrusions is amazing. Also, the dual smooth rods for the X axis should be OK, but I would definitely switch to railby MatthewHall - CoreXY Machines
I would consider using a Stacked CoreXY arrangement like so: I built my printer this way and my design is so much shoddier than yours. This prevents any risk of the belts slipping off the pulleys or other bad things. Belt wear shouldn't be that much of an issue. What could hurt you though is belt stretch: if your printer is a certain size that 0.001 of strain might start to seem like a lot. Alsby MatthewHall - CoreXY Machines
Quoteboylucky Hello Matthew, please, would you have a link to such design? Thanks. Found it! (No I haven't been looking this whole month). Just stumbled upon the old forum link and accompanying design inspiration I was talking about.by MatthewHall - Developers
What about degenerating crepes?by MatthewHall - CoreXY Machines
Can you 3D print crepes?by MatthewHall - CoreXY Machines
My first one was a CoreXY I designed and built myself with Hiwin guides and maybe 6 printed parts. But it is much more complicated than a cartesian system. Aluminum is the way to go.by MatthewHall - CoreXY Machines
Let's design one. I've noticed that the majority of new CoreXY designs are "lone wolf" endeavors. Sometimes I wonder what this community could do given a proper Slack chat, Github repo, and CAD system. Instead of undercutting a traditional printer we could work on a system that suits the needs of Reprappers, not of consumers/businesses. Also, the more people that are gathered to work on this, theby MatthewHall - CoreXY Machines
Looking... if I find this will be the first place I come!by MatthewHall - Developers
Very interesting... could easily be more rigid than most SCARA designs. Have you seen that printer with a jointed arm in the X, Y, and Z axes? It's kind of like a mix between a SCARA and a Cartesian.by MatthewHall - Developers
I'd just like to say thanks to this great community. Time for some before/after:by MatthewHall - General
My apologies I totally forgot about this post! Maybe I should think before I post but meh. I filmed this earlier but forgot to post until just now. 3D Printer Video #0 As of now I'm having much greater success.by MatthewHall - CoreXY Machines
This is sweet, just for the record.by MatthewHall - CoreXY Machines
That's right, 6. Working out something I think I broke in one of my steppers or possibly the voltage regulator. Gotta love linear rails though, the quality is absolutely stunning! Just thought I'd share this glorious achievement in this field.by MatthewHall - CoreXY Machines
Whatdd'ya know, three years later, same issue.by MatthewHall - Reprappers
I think you need a new website. I'd be willing to do it for free, as I am just getting started in the field (still in high school). Contact me if you'd like to further this endeavor. TBH, the logo is nice but the rest of the site is quite lacking in design. To continue to spread the Reprap movement we must continue to e user friendly and excell in design.by MatthewHall - Tantillus
Quoteprot0typ1cal I'd fix your belt routing first. Go ahead and rapid through your XY limits. Let us know how that works. Regarding bigger steppers, Smaller steppers won't effect overall print speed by lowering the accel/decel rates, as much as having to limit print speeds because the belts are out of plane and twisted. Wacked belt routing is also going to limit your available/reliable print voby MatthewHall - CoreXY Machines
Is there any way I can use the motors I have now or will I have to order new ones?by MatthewHall - CoreXY Machines
What do you mean exactly? Is 12 volts too high for the power supply (12 volt output)?by MatthewHall - CoreXY Machines
I had these two options: ...and I picked the cheaper one.by MatthewHall - CoreXY Machines
I can help you with that. Reply if you need help. Just finished that on my printer actually.by MatthewHall - CoreXY Machines
The printer is rather large (bed 10x11 inches theoretically) but the only part I've used is the middle few inches. The mass of the axes is pretty light, just a few 3d printed components, the rails (12mm versions) and a bowden E3D. Don't know if that helps. Back to debugging in a day or two once I get time away from education... Edit: so if my motors aren't weak enough then it won't have enoughby MatthewHall - CoreXY Machines
Quotethe_digital_dentist In the second and third images, the belt does not appear to be parallel to the X axis. That is going to cause distorted prints. In the fourth image, the motor looks much too small to be driving any but a tiny coreXY mechanism. That is probably why your motors are slipping. So should I get new motors?by MatthewHall - CoreXY Machines
Will do tonight. Again, thanks for all the help.by MatthewHall - CoreXY Machines
