RE: Prusa Bear Mini Mk3s
Hi jmac. I use OEM Prusa smooth shaft pin for the idle pulleys
RE: Prusa Bear Mini Mk3s
Thanks Tomson 👍
yes I have everything i need now, just have to wait on aliexpress shipping 🤮
RE: Prusa Bear Mini Mk3s
Can someone tell me the overall dimensions (without a spool holder but including any room for movement/plugs) that I would need to build an enclosure for on this unit?
RE: Prusa Bear Mini Mk3s
Does this frame allow you to use the original z height? I also am not interested in getting more height. I only want the ability to make the chassis stiff and put on a direct drive extruder.
Thanks guys for all your hard work
This looks a great mod.
A few questions if anyone can help please?
I'm going to order the specific mini bear upgrade kit from aliexpress from blurolls.
I want to use my current mini Z and smooth rods as i'm not bothered about gaining for height from Z, so will print out the stuff kindly provided by tompson for that.
I will order a new official Z motor from prusa.
Do I need to order new belts for X and Y and new bearings etc?
What is a good new entire hotend with direct drive to get? one from aliexpress or?
This new direct drive hotend will fit on the mini X smooth rods and belts?
I just want to make sure I get everything ordered at once as the postage costs are very high.
here is what i currently have, any help with what i still need please, hotend etc, can i get the hotend from some other company or?
@3dpgva
Hi again. Yes the stoplimit i found out yesterday than i did the wizard. I put some temporary limits but i think i put them 1-2mm to high. I was to exited to start printing so i save that for today:)
@firstlayer
Hello there, can you show a picture of printed part and the profile, and we changed the name to pear3D now 😀
RE: Prusa Bear Mini Mk3s
Yes this is standard height, you can use the original mini Z or a mk3s Z,
You could probably also cut the Z extrusion to lower it say 10 or 20 mm ? going by pictures on tomson and pear3d.ch
RE: Prusa Bear Mini Mk3s
Yes. You can use OEM MINI Z-height. It´s 20mm lower than my extrusions bec. i use OEM Mk3 bear height on Z but it´s no problem to use full Z-height from the MINI and it´s very stiff so it´s no problem to use direct drive. I do not use the full length for printing but only use it as an extension for filament feeder and led-light
RE: Prusa Bear Mini Mk3s
i can't wait to put a filament roll on top of the frame like the mk3s+ 🤣
The little things in life make me happy 😌
RE: Prusa Bear Mini Mk3s
I understand what you mean😊 most of my print fits the MINI and i prefer to print on them before my mk3s. Some of it bec. of the meny with 32bit but everything feels better and smoother.
RE: Prusa Bear Mini Mk3s
Yes for sure I love the 32bit and the fancy screen.
One thing i just can't get right on the mini no matter what I do is PETG, I have tried all sorts but it always strings and blobs, the same PETG prints beautifully on the mk3s+, I'm hoping when I do the mini bear upgrade and add the mk3s+ full hotend to it that it will print PETG like a mk3s+.
Did you ever have trouble with petg on the standard setup mini?
RE: Prusa Bear Mini Mk3s
No PETG was never a problem, shore it prints better and nicer now but not really a problem. I had most problem with some silk PLA like Extrudr. Most of the problem i ever had both OEM and with Bear-kit have bin heat-creep sometimes. Better with Bear-kit and totally gone after the hurricane build. Same with sag after printing in enclosure in high temp for a while i have had sag on the Super Pinda mount. That is also gone after the Hurricane. I have a M3 skrew mounted next to the Super Pinda to not let any sag of the mount.
RE: Prusa Bear Mini Mk3s
And when you did petg on your original stock mini, did you change retraction or speeds etc or just all default settings?
RE: Prusa Bear Mini Mk3s
hi guys
What is the "Smooth rod - Special" part for? how does it differ?
Thanks
RE: Prusa Bear Mini Mk3s
What is the "Smooth rod - Special" part for? how does it differ?
-it doesn't. I guess they call it special in china if it's round enough 😉
[Mini+] [MK3S+BEAR]
RE: Prusa Bear Mini Mk3s
ah, sorry... I though you were talking about rods (as parts).
I'm not familiar with Mini BEAR... maybe "special" means different rod diameter? I think you'll need to download both stl versions and look for differences in CAD software.
[Mini+] [MK3S+BEAR]
RE: Prusa Bear Mini Mk3s
i printed both, diameter is same. @tomson or @pear3d.cd will let us know soon 🙂
RE: Prusa Bear Mini Mk3s
can you give the link to all printable parts (stl files)?
