Hi Need included part to be CNC'ed from CF sheet, 5mm thick. This is for 3d printer so needs a stiff type of CF. Please sent me a quote here or via PM. I'm based in UK, someone local would be preferable...by hedeon - Job Shop: I need stuff made!
Quotedeckingman For info, I'm just in the process of replacing my 5 off E3D Titans with 5 off Bondtech BMGs. If you want to know why and/or you are serious about wanting to print multi colours or multi filaments, take a look at my blog (linked in sig). HTH Edit. When you are buying 5 extruders, getting the wrong ones to start with can be a very expensive mistake (as I found out to my cost). Yesby hedeon - CoreXY Machines
I think I have stated previously that I already have such system in my Prusa i3 style printer and why I don't want to go direct drive. The point of the new printer is to make things differently, experiment, push the limits. Besides, later in the thread, I have said that the problem was solved with using e3d hobb-goblins and Titan. Not sure how inputs like this contribute to the discussion at all.by hedeon - CoreXY Machines
Yeah, I think I will look for some better belt+idlers solution. As I said, it started as Hypercube Evolution, but I was not sure about steel core belt on 12mm idlers. I was expecting that belt will actually deform on those idlers, but I can't see this happening after a month or so of prints. What I am worried about is stretching as each loop is almost 2.5m long... The task for today was to look fby hedeon - Printing
gt2 6mm polyurethane belt. Well, I threw away that old twisted one where it was clearly visible, but I replicated it on some of the photos how it looked like on some leftover I had. And some photos, in google photos album for better resolution... Photos of the machineby hedeon - Printing
That's actually a very good few ideas there, food for thoughts. Thank you, guys. When building Z axis I have realised that smoothness of movement is not ideal, but I had to choose between play in the bearings and smooth motion. Decided that play in bearings will cause more harm, so linear motion had some glitchy points. I am right now printing two 300mm long walls, one on the front of the buildby hedeon - Printing
I am finishing the build of my first self-designed and built a 3d printer, which is massively inspired by Hypercube Evolution. I am tuning and tweaking it and one of the issues I have encountered are some sort of inconsistencies in layers. I don't know if I am not expecting too much from this machine as this is mostly only visible when outlines are placed directly above each other, forming a verby hedeon - Printing
Quotewarbunniex Ya a drill press and a saw/ angle grinder is all that is really needed but plenty of people only have a printer for a tool (i have access to a great metal lab but i try to give suggestions that give wider options for people. this is reprap afterall) Yet, that is true. I own 2 3D printers, angle grinder and mitre saw, that's it really. I am building a nice workshop for my self inby hedeon - CoreXY Machines

With multi-extrusion in mind, it might not be as effective. And the printer will be completely enclosed and carriage is already quite close to top cover. I designed it to fit under my desk, therefore, there is no option to make printer taller...by hedeon - CoreXY Machines
Quoteo_lampe QuoteI have received cloned Titan too... Terrible. Machined tooth profile is even not on the path of the filament... That's what I had on my genuine Titan, too. Turns out, the plastic gear wasn't pressed deep enough on the output axis, so the gear pushed the arm lever out of the filament path. I could adjust it with some careful applied force. ( I used the small hammer ) No, everyby hedeon - CoreXY Machines
I have to say I really like the idea to adjust tension through motors, but it might not be as easy. I am planning for full enclosure so there can not be any sting out parts, and don't really have access to the milling machine to make such nice metal brackets. Limited to 3D printed parts, so chunky brackets. But it is a good idea worth exploring...by hedeon - CoreXY Machines
I need some advice. Again I am in the middle of the process of designing and building my CoreXY printer. I started out wanting to build Hypercube Evolution, with linear rails mgn12h style instead of smooth rods, but in the process of making adaptations, entire design has changed a lot from HEVO. I don't think I should call it HEVO anymore. Anyway, I digress. One of the biggest challenges for mby hedeon - CoreXY Machines
Thanks for recommendations. In the meantime, there were some developments. I have fitted into one of the extruders now hobbed gear "hobb-goblin" from E3D, and there were cracking noises coming out from the extruder, Bowden tubes were popping out of collets, but it didn't grind the filament. Obviously, I have reduced motor current so it is skipping steps rather than destroying my extruder. Encouraby hedeon - CoreXY Machines
QuoteArchiclem I think that you could go for cheap titan ripoff (trianglelab ones have been reviewed on the forum by demondj) .... But it won't be supporting the great e3D... Anyway.... Thank you. I would have already bought genuine e3d Titan if I was 100% sure it will solve my problem. That's why I have bought a knockoff. I know it is not the same quality but it might show a step in right direby hedeon - CoreXY Machines
QuoteArchiclem I use a fliying extruder in a delta which is a bondtech bmg.... It works really well... They are indeed expensive but they always work! You could use this one it is recommended by the dice 3d printer which is a very fast tiny printer.... Anyway, my experience with Bowden : the longer the worse... Except from they ultimaker, i've never liked bowden.... Good luck Yeah, Bondteby hedeon - CoreXY Machines
Quotedc42 We are still working on both sensors. The rotating magnet one is more accurate. The printed assemblies we used for the prototypes are not suitable for mass production, so we have teamed up with another company that has the experience we lack in manufacturing mechanical assemblies. The laser sensor is less accurate but still entirely adequate for detecting loss of filament motion, so weby hedeon - General
Hi Haven't posted much but have been long time lurker. I am in the process of designing and building my own corexy printer, and by most part, I am trying to go on my own, sometimes I just need advice from someone more experienced. My previous experience is with Prusa i3 clones using direct drive but for this large-scale Corexy I decided to go with Bowden setup, and boy, it made my grief. My mainby hedeon - CoreXY Machines
