Here is a little rundown on my new Eustathios (by +Jason Smith) which is variant of the Ingentis (+Tim Rastall). Video is kind of long but I give an overview on the new printer and also show my large CoreXY printer which was the first printer I designed and built.

Awesome work Eric.
The Alu bed on my Ingentis has a hole cut in it slightly larger than the silicone pad: That allows the pad to be in direct contact with the glass with (insulation underneath) and significantly reduces the amount of aluminium that sucks up heat.
Also, I recon your core xy could happily convert to a hybrid Ingentis design I’ve been playing with. I’ll send you a link
Very nice. I like that braided wiring sheath. I tried to buy some of that but they wanted a 500 meter min order. I now see you have your high belt in front of the low belt on your CXY. That would fix one issue i have with crossing the bearing. I may change mine.
Will you be enclosing the build area? You’re mentioning issues with the Core-XY retaining heat with PLA which seems interesting to me, as it’s not anything I’ve encountered (You’re seeing whole domains of different problems based on Belts and enclosures and I have problems with effector bucking that you wouldn’t)
Quite frankly, your printer has me rethinking things like the Z-axis on my Quadrap/Ingentis, luckly I’m not far enough into it that I have to back-track any.
What are you using to restrict movement vertically? Linear bearings or bushings? Where did you source the leadscrews?
Printer looks awesome. I’ve been so lax in my build, but seeing your video has lit a fire under my butt to get going again. Nice work!
I’d be interested in knowing where you source your lead screws for the z axis.
@Mike_Smith & @Mike_Miller the leadscrews are from Misumi on both printers.
As far as restricting the leadscrew vertically the Eustathios uses bronze bushing in a flange, thrust washers, and shaft collars. The Corexy uses skate bearings at both ends, printed flanges and shaft collars. Hope that makes sense.
@Shauki I have to disagree with your candle heated plate idea. I know that if I don’t have my heat bed at just the right temp (+/-5 degrees then my ABS parts either come out con-caved at the bottom or end up not sticking properly to the plate and curl up on the edges. My perfect bed temp for printing ABS is 90c. If I go to 110c like most other do I get this weird thermal pocket for the first 5-10mm which makes my parts con-cave on the sides really bad. If I go any lower than 85c then my parts curl so the bed temp needs to be regulated pretty consistently to produce good parts.
Cool Printer, and very interesting facts about the CORE-XY. Could you please repeat the name of the machine? Thanks!
@Lucas_Campa_ePoxi which one? The new printer is what I call the Eustathios Spider (because of the color scheme). Jason Smith designed the Eustathios which is based on Tim Rastall’s Ingentis, which was inspired by the Tantillus by Sumblime, which may be inspired by the ultimaker I think. Unless it’s the other way around… I am not sure.
The other one is my design. I called it the Lien3D Corexy.
The models for everything I built are on github https://github.com/eclsnowman as well as the original parent printers sites.
They are in multiple formats and the corexy is a little behind. I have been too busy building and now testing to get everything up to date.
