Mine was purple, I was trying to print on an I3 at about 30mm/s Just too much trouble for me I guess LOL, I hear my PLA running now doing just fineby n9jcv - General
Can you tell me how much the MK8 weighs and what is total length? Also will the top of the MK8 support a screw in PTFE bowden adapter? Thanksby n9jcv - General
Seems all over I was reading how wonderful PETG was. So I bought 1kg from Hatchbox. I have only ever printed in PLA, for about 3 years now. But I decided to try PETG. I decided to swap out my PLA hot end and put another hot end in so I did not contaminate or mix materials, as I had read some people had trouble with that. So brand new hot end, machine tuned perfectly using PLA. Things peopleby n9jcv - General
kd6hq Thanks for the comments. I really dont see a big deal with 2 z steppers. I have an I3, running for 2 years and it has never gotten out of level. The steppers always seem to be in sync. Once leveled it is done for me. I don't use autobed leveling, just did it once very well and used bolts and nuts to secure and from there it holds. Mind you it would get out of sync if some just deciby n9jcv - CoreXY Machines
Origamib, That is very good. What printer is that, a corexy you designed? That is the point I guess everything has pros and cons, you can over engineer to avoid issues or use lesser parts and accept compromises. I do not have any metal capabilities. Just what I can do with a drill and miter saw. Mostly just cutting the extrusions and drilling. So for me this means I have to accept compromby n9jcv - CoreXY Machines
So a little background, I have been 3d printing for about 3 years. I first built an I3 aluminum frame from a kit. Then I build a cherry pi delta. When I built the cherry pi delta, I designed a new effector, arms, carriages, partially due to my want and partially due to materials I already had vs what I could not obtain cheaply, etc. The cherry pi turned out great. Next I built a 100% customby n9jcv - CoreXY Machines
Can anyone tell me how much distance there is between the top front 2020 and where the belts cross near the center of that extrusion? Also is home 0,0,0 top, front right? Also if I leave the belts as is but make the cube wider but do not mount the right side in the corner but 2/3 of the way from the left would the corexy still function properly? Thanksby n9jcv - CoreXY Machines
Thanks Ax. So why does the y rod holder have 2 8mm holes i understand the one and the 2 bolts to clamp but what is the purpose of the other hole? Also I am thinking of supporting the front of the bed with a center smooth rod. Has anyone tried that?by n9jcv - CoreXY Machines
Hello everyone, I am about ready to start building a corexy and I am pretty settled on the FB2020. I have looked at thingiverse, git hub and read some here but I have a question. On the Y rod holders, and I am assuming the Y axis is the front to back movement, with one rod on the top left and one on top right. In this picture from the github build log, the Y rod hold is orange, it is between theby n9jcv - CoreXY Machines

Sorry another question, how solid is the wood in the Lak, will screws hold or will they not have enough wood for a secure tight connection? Thanks againby n9jcv - General New Machines Topics
Also what are the m4 Brass inserts for? Sorry for so many questions, but your project is VERY interesting. I think there is not much traffic on this thread because of the category. I think if it was in the General category there would have been pages of responses. bby n9jcv - General New Machines Topics
I see your spreadsheet list the cam nuts from Ikea. Do you have a part number for the cam nut and screw, or pic or measurements on them. I would like to pick some up. Also, do you have any pics/drawing on how to construct the cube like that. I can't envision how to put it together that way. Thanks bby n9jcv - General New Machines Topics
Thanks for all the details. Can you provide details on the cams. I would be interested in doing this without screws but I can not picture the actual cams or design. Thanks!!!!by n9jcv - General New Machines Topics
by the way, I love the sketchup, that is AWESOME !!!! I don't think I could do that that is a very impressive sketch. So far I have just modeled individual parts, never an entire machine.by n9jcv - General New Machines Topics
rklauco , I am just gonna throw 2cents out there. If it were me, I think I would remove the bearings at the top of the z lead screws. Just let them float. That will eliminate the noise and from what I have read, z wobble is worse with constrained lead screws/5mm shaft. bby n9jcv - General New Machines Topics
Wow, this seems really cool. Like it has been out for a while but this is the first I have seen or heard. Seems like you have been working on it for 6+ months rklauco? I checked the latest pic, it looks really nice. I am contemplating building one or at least buy 2 tables and designing/building/moving a Prusa I3 into it. They sell the tables in yellow, which I really like. Now that yoursby n9jcv - General New Machines Topics
Look at this printer, a cartesian in a extrusion cube. Vulcan 400 This printer uses 2 motors/belts for the y axis. Would the Y axis still function properly with a motor and belt only on one side? Or would there be binding? Thanks bby n9jcv - General
You could implement a Bowden feed to eliminate the x motor in the gantry or use a Titan like extruder with a pancake geared stepper motor. I am thinking to build one of these with the Titan extruder. I feel the corexy elaborate belts are tricky and problematic. Anyone have designs for these? The reprap machine wiki does not seem to mention them.by n9jcv - General
Yes like that but i am sure FT did not invent. What style machine is that. And how in speed and quality would that compare to a corexy assuming same builder and design and construction?by n9jcv - General
So what if you build a cube frame, like the corexy uses. For z you have a bed that goes up and down. For x you have a single belt and carriage like a prusa i3. For y the x carriage moves back and front with a single belt like an i3. What type of machine is this? Where are some existing designs? Thanks Bby n9jcv - General
Well, using the above as a learning experience here is what I did. Prusa I3 - 50mm/s .3 layers, .5 nozzle, .5 shell and top/bottom layers 10% fill PLA 202C It came out wayyyy better than I expected.by n9jcv - General
Graymatter, First let me say, thanks for all your effort. Here is my 2 cents. I am nowhere near an expert, just my opinions here. #1 It seems to me that you could increase max height for Z to 300 or even 400mm for just the cost of longer rods and a lead screw, but maybe I am missing something. But I think this would be money well spent. #2 - again I am no expert, but it seems to me thatby n9jcv - Look what I made!
Has anyone used these chinese stepper expansion boards to add a 3rd extruder to Ramps 1.4? chinese stepper expansion board If so, can you share any pics, pinouts or wiring diagrams. Seems there is no documentation for these chinese boards. Thanks bby n9jcv - General
Can anyone tell me in the US where you can buy RADDS v1.5. Makerfarm lists them but out of stock. Is this board still being produced? Thanksby n9jcv - Controllers
You could try a new stepper driver in e1 if you are currently using e0 on ramps. This woul tell if ramps or the driver are the culprit.by n9jcv - General
Your math seems correct. Is it possible that your extruder is slipping, either physically or missing steps? Also you did not say if you are reloading firmware or saving to eprom. Is the filament easy to push thru the at temp hot end?by n9jcv - General
Personally, I think you CAN do it with our help. It will take time. First get us some pics closeup of various views. If you have a Windows computer, us the Paint program. Open the pic, and use the resize option. I think the forum limits the pic size to 600mb. If you post your pics someplace else you can simply give us a link to the pics. Then you need to test each item independently, and cby n9jcv - Prusa i3 and variants
I have used 3 chinese E3D clones over the past year. They have all worked flawlessly. They have never failed and never clogged. I print PLA only(200-205C). They all have the teflon insert. All have been with a .5mm nozzle. I took them all apart and re-assembled, just to ensure they were assembled properly before use. The cost between $4 and $20 each.
