Re: How well do the printed parts right underneath bed hold up to heat?

If you're planning actively heat your enclosure - you need to make all of your printed parts from something that will resist the heat. I'd suggest CF-filled polyamide. There are numerous other options I can suggest, but I'd first need to know if you're based in Poland and what's your printing capabi...

Re: SFU1204 or 1605

Thanks, that's what I thought but couldn't explain why. It's due to the pitch of the thread... It's not. If you have a 200step motor it's 0.025mm (25 um) per step on 5mm pitch screw, or 20um for 4mm. Both are fine for typical layer heights. It'd be advisable to use 0.16mm instead of 0.15mm layers o...

@MirageC have you abandoned this idea? I can't find v2.8 files on Github, link from the first post doesn'work.

Re: HevORT Heavy Duty - HD9mm and HD12

I'd like to have A/B motors hidden. What do you think about adding external frame and mounting 2mm steel sheet panels to that?

Re: Frame joints quality (and other frame questions)

[ firegun I talked with Grzesiek fron Hobby Store. He just bought 4 tons of profiles that are Made in Poland by Altrax to his spec. He cuts them with 0.07mm precision. https://hobby-store.pl/en/t-slot-30-type/altrax-aluminium-profile-3030-t-slot-type-black-matte.html I need to calculate if I'd go wi...

Re: Frame joints quality (and other frame questions)

I'd like to avoid buying products made in China building my projects. Both because of ethics and quality reasons. That's why I'm searching for better alternative, not necessarily the cheapest. If Item would make 30x30 profiles, I'd go with their solution, even if it'd cost more than 1k EUR (very lik...

Re: Frame joints quality (and other frame questions)

4. @MirageC is it viable to use other methods of joining profiles? Eg. drilling and tapping holes instead of using L shaped inserts?
Of course I'd reinforce frame adding corner brackets and inner outer steel sheets.

Frame joints quality (and other frame questions)

Hi, 1. I'm wondering if it's worth getting stell L joints (like those): HBLBS6 https://uk.misumi-ec.com/pdf/fa/2014/P2_0599-0600_F40_EN_001.pdf They are 4.45EUR/pc which adds to 115.7EUR Dold mechatronik has similar, but die casted from ZnAl (this alloy is called sheissmetal, at least in Poland ;) )...

Re: Garolite Equivalent

Hi,
EPGC308. Should be on your list of higher end print surfaces.
It's G11 equivalent with 180C long term stability.
There are also 220C versions available.
I'm planning to have four interchangeable print surfaces:
1. G11
2. Robax
3. Delrin
4. Powder coated PEI

Few modifications for Z axis - are they viable?

Dear All, I'm thinking about building HEVORT HT, but I'd like to make few modifications, mainly to Z axis. I'd like to consult with you those changes (I'm able to do the work mostly by myself, but I'd really appreciate your help). 1. Replacement of 3x150mm MGN12 with kinematic coupling. Reason: a.th...
