Wow this is really awesome, didn’t know 3D printer has evolve to such extreme. Good job there. I am still waiting to see someone really do something in measuring the expansion of the bed and also the Thermal creep that really occurs near the hot end and also the extruder before n after delivery of plastics( somehow done by CNC kitchen). This 500 is really massive can print more than most printers in the market. Very well done 👍 love it 😍
Well down Julian , I'm Sparky by Trade, and you have done well, very interesting setup. Love to see how you wired up the EBB36 to the extuder, as Marlin is going down the same path with adding this to their boards.
I padded my bed out with printer paper but then someone suggested I use tin foil, I thought the paper was close enough but the tin foil got me slightly closer. thats a nice RatRig, Z tilt was a gamechanger for me, starting from a level playing field makes the rest of the calibrations so much easier!
Ha, nice; re: "someone suggested I use tin foil" -- we have a ten year anniversary coming up. Tin and aluminum are options. Perhaps she'll accept a bed-leveler? :) (Gutter joke in there, as well... :) )
Hello Julian....seeing your 500 x 500 printer has peaked my interest in building a large format printer. I have been researching the different options available. ie: Voron Phoenix, Rat-Rig, custom. I wonder if in your opinion, I could scale up a rat-rig mimicking your modifications to have a print area of 660 x 660 x 660. My interest is in prototyping larger parts for experimentation. For example, I would like to be able print 24" round spheres. Most likely in two half spheres then joining. Back to my question...will the 3030 extrusions be large enough or will 4040 be a better fit? Can the 160 mm longer X beam work without adverse vibrations or lack of stiffness. I was hoping to just mimic your printer design by scaling the extrusions and guide rails a bit longer. Thanks for your feedback in advance.
A lot more work will be required to use 40x40 as all the components will need to be manually adjusted. 3030 scaled to desired size will be a lot simpler task. 30x30 is very rigid. Will be a good project.
@julianjc84 Having run a 500 for several months now, next major teardown is getting AWD at least, and most likely 48v. You should seriously look into it. Also motor decouplers, which usually include upper motor shaft support, or at least two bearings holding the shaft. Huge difference. Belt length is your biggest enemy at this size.
Where did you buy your 3030 extrusions? I couldn't find any in Australia without the step in the slot that makes the MGN12 rails fall in, ended up having to import them directly from RatRig
I have an old CR10 S5 (500x500) do you know where i can get a PEI sheet for it? Also, do you have more info on your build? I believe this may be a direction to go with mine.
I have a problem with the input shaper through EBB36. It is difficult to measure, perhaps because the printed part is shaking. What about your EBB36? By the way, when using 2 motors and 4 motors, how is the result of the input shaper different?
I only use 2 motor setup, 1 for x 1 for y My input shaper results are pretty standard when compared to my other printer. I will have to find my graphs, I really should recalibrate after changing my extruder to a Sherpa mini
How is the shape of the bed itself? If I use milling on such a plate I get tolerances of +-0.05mm. So is the cause for such high tolerances maybe the gantry?
Nice printer but the bed is too big to be 1 piece... I might mod it from 4x Ender 3 beds 230mm each with ssr relays so only 1, 2 or all 4 can heat up if needed for smaller prints.
No issues with bed 1pce. Heats up really fast with a 1.5kw at 80% power and holds heat no problem. Padded out the slight uneven of the bed/magnetic sheet/pei sheet with paper. Beacon does a great job.
