QuoteRoberts_Clif I use 80/20 Inc They have many sizes already cut just select the precut sizes. If anyone uses 80/20 keep in mind they have a smaller slot size so not every drop in or slide in nut will fit. I just got some 80/20 2020 and had to order some slide in nuts that were 2 or 3 times more expensive than standard ones. BTW if you know a cheap source for ones that work with 80/20 pleasby fauxsoul - Extruded Aluminum Frames
Chiming in about Granger; would suggest against it, they carry 8020 brand which is non-standard and has a 5.26mm slot instead of a 6mm slot like most other brands which means that most nuts drop in or slide in will not work. I learned this the hard way./by fauxsoul - Extruded Aluminum Frames
I would never dispute the value of a duet board, they seem really great and I've heard a lot of good things about them. I might even buy one eventually when I move on from this printer, that being said it surely doesn't fall in line with my usage scenario with this printer (which is a budget printer). What surprises me really is the lack of options, you've got RAMPs which is $15-$20 then if youby fauxsoul - Extruded Aluminum Frames
Yeah, it seems like there would be more good options available. I want to have a decent set up and a good board, but a RAMPS setup is like $15 VS something like a smoothie board or duet or any of the nicer boards are multiple times that amount. The printer that I have right now I got on sale was $230 and it has a melzi board, which I don't really dig (I know that it has some of the same probby fauxsoul - Extruded Aluminum Frames
Will definitely watch your video, aside from what you are working on right now are there any boards that you could recommend that are currently available?by fauxsoul - Extruded Aluminum Frames
I'm going to be using an external mosfet like the one below for the heated bed, I've read about some of the power issues but those are only related to the heated bed power draw right?by fauxsoul - Extruded Aluminum Frames
Yeah, after I ordered them I started seeing some things online about some of the problems people have with them. I think I will just order a set of A4988s since they are so cheap anyways. I'm just going to be using a RAMPS board for this printer which has SPI so I think I will get 2 TMC2130s and use them for my X and Y, and maybe I will use a DRV8825 for the extruder if I don't run into any issby fauxsoul - Extruded Aluminum Frames
Thanks for the input. Haven't been working on lately but I did get a few parts in yesterday so I'm going to try and work on it soon. I got some anti-backlash nuts for my lead screws and got that ball screw thing so I'll have that for when I am ready to make this transition, but I'm going to need to buy some more bolts and probably some more t-slot nuts before I'm able to finish things, underestby fauxsoul - Extruded Aluminum Frames
Still thinking things through but this is a simple drawing of what I have in mind for keeping the bed pressed against the ball screw, basically a simple spring pinch clamp: The other option that I can think of would be extension springs like this I tried printing some of these brackets (in addition to using the metal ones) to see if things might feel better and it seems to be a good improvemby fauxsoul - Extruded Aluminum Frames
I've got some of these. I think I want to either get or print something like these, which have 2 anchor points. The longest length of extrusion that I have is 380MM but it will be braced in the middle as well as the ends when I am done. Oh no, I wish I had that kind of ball screw, but nope. Just want to use this one as a fixed height pivot for a 3 point bed leveling setup. I have an idea tby fauxsoul - Extruded Aluminum Frames
I've got quite a few of the triangles and I ordered 2 brands and have way more than I need, but thanks though. I just feel like the triangles don't do anything to help ensure that the actual extrusions are square and aligned, I'm just going to print or buy some that have multiple mounting points and use those where possible, probably just print some. I ordered this ball screw which I should bby fauxsoul - Extruded Aluminum Frames
Wasn't aware anyone else was doing that type of remote-direct drive setup. TBH not really impressed with the zesty nimble and have no want or need for one. It looks pretty janky, the idler bearing assembly looks really flimsy and I would not pay for that kind of design. That Flex3Drive system looks pretty cool though, maybe I'll look into that next time. Finally got my 'economy nuts' in, I'm pby fauxsoul - Extruded Aluminum Frames
Is that a flexible shaft / direct drive extruder a la zesty nimble? That printer looks pretty nice. Have you guys decided on what to do about part cooling? I cut some of my aluminum and was starting to put the frame together only to realize that the aluminum extrusion that I have is special snowflake extrusion and doesn't have the regular 6mm slot that every other extrusion has (it's 5.26 iirc),by fauxsoul - Extruded Aluminum Frames
Dealing with the x carriage doesn't really bother me at all. and with this hotend there isn't clearance for wingnuts, the bolts are right on the sides of the hotend and wingnuts wouldn't spin. When I get around to dealing with my bed leveling I think am just going to take some longish M3 and file/sand most of the threads off then put those through the empty screw holes that I have so that the beby fauxsoul - Extruded Aluminum Frames
All I would have to do to remove is is take 2 screws out of where the fan meets the heatsink and unscrew 2 screws from the bottom and it would lift out, if anything it's going to be easier to take off then it is right now. Still have to sort out how I am going to do part cooling though.by fauxsoul - Extruded Aluminum Frames
On this printer I am not going to be changing the hotend, it's already an all metal MK10 hotend (and again not going to be spending more money on this printer, eventually it will just be my secondary printer). The extruder assembly is going to be easy enough to remove as it is (if I need to do any maintenance). The bearing holder area is 50mm the main body is 70mm and things fit perfectly, it'sby fauxsoul - Extruded Aluminum Frames
The bearing holding section is actually 50mm long so you could go with 3-4 lM8UUs or 2 lM8LUUs. Right now I have the 2 LM8LUUs that are on my printer and I will probably use those. Idk if I'm going to replace them or not, will probably decide later, I can always order some online if I decide to. I wish those encased IGUs were not so expensive. I would love to have linear rails but I don't want tby fauxsoul - Extruded Aluminum Frames
X carriage so far. Pretty much done there, just gonna design the cooler now and place an anchor point somewhere for cables. Probably still going to be a couple weeks before I get the rest of my parts.by fauxsoul - Extruded Aluminum Frames
Yeah I actually modeled the belt first and then worked around that so it's going to be good there. I'm definitely going to be changing how things look a bit by at least doing some chamfering and probably making some holes in it too, but honestly I don't really care too much about how things look.by fauxsoul - Extruded Aluminum Frames
Thanks for the info, when I get around to actually building the models that I am going to print I will check it out. As far as the extrusion goes I'm only going to need a couple more meters so I can get the rest on Amazon (with prime) or apparently grainger has it @ 31.50 for 4M which seems reasonable since I can avoid shipping costs completely by picking it up in store. I think I am just goby fauxsoul - Extruded Aluminum Frames
Aaaaand now that I have the dimensions figured out I realized I don't have enough 2020, so this will be put on hold for a while, but hey, at least I will have more time to deal with making the models though.by fauxsoul - Extruded Aluminum Frames
Ordered a ball screw for the bed, just happen to find it while browsing banggood: Eventually I do want to build a coreXY, but I will want to design my own parts because when I do build it I kind of want it to be my endgame fdm printer, but before I go and spend that kind of money I want to get my feet wet dealing with this first.

The whole moving Y axis really seems non-ideal in the first place, but I'm working with what I have here for now. My y carriage is a 5 hole 3mm aluminum plate, specifically this one: I was thinking about using a 3 hole setup mounted similar to what this person has done here (with a ball gymbal on one post and 2 other adjustable posts).

Quotelkcl Quotefauxsoul Was thinking something like this. I don't mean to sidetrack your thread here but this printer is pretty close to what I want. not a problem. hmmm... in the proposed design diagram, i would find it hard to design an x-carriage that fitted say 2 horizontal rods separated by 70mm in between them, plus say 15mm extra each side for the LM8UU bearings plus a bit extra for sepby fauxsoul - Extruded Aluminum Frames

I was thinking something like this. I would like to have the z steppers mounted from the top to get the most out of the leadscrews that I have with the leadscrews going between the two main z posts.

No idea, I'm just about to throw my duplicator i3 onto a 2020 frame and I liked how it has 2 beams in the z axis it seems like the best design for sturdiness aside from just building a box (which seems excessive on an i3 style printer). Just need to go about designing the parts around the existing hardware I have and was looking for inspiration.by fauxsoul - Extruded Aluminum Frames
