MK3S Bear clone advice  

answers

Posted by: @cpu

I need advice regarding MK3S Bear clone from FYSTEC + few other parts:

I've got original MK3S+ with Bondtech Extruder and as more and more parts are in boxes I'm thinking of building clone - so on the list:

• FYSTEC Bear Clone https://pl.aliexpress.com/item/33018805883.html?spm=a2g0o.store_pc_allProduct.8148356.6.402c77a6B5YE3V
• Trianglelab Bi-Metal Heatbreak https://pl.aliexpress.com/item/1005001927523189.html?spm=a2g0o.store_pc_allProduct.8148356.2.673c5aad17xKAN
• Trianglelab Extruder Upgrade (BMG clone) https://pl.aliexpress.com/item/32998931899.html?spm=a2g0o.store_pc_allProduct.8148356.4.29267a03fRnikU

What about plates for Bear frame? I can't find them anywhere. Also, BMG clone has 3 versions I assume cheapest is the best option, or should I check something else?

Any help is highly appreciated.

I have used all three of these and I build this exact clone.  Why do you want a clone?  

Bear Clones are ok, but they do not come with support. I was able to follow Bear's instructions to build my printer and it worked well for over a year.  It continues to be one of my better printers.  That being said, it has required some tinkering.  It also does not come with printed parts.  

The Bimetal heat break is a quality alternative to the e3D parts.  They work, but you may need to do PID recalibration.  

I have one of the BMG.  I did not buy version 3, but a version from another manufacturer.  It would and appears to work as well as the Bondtech version for which I have two.

It's idea to use parts that laying around to build second printer - I've got complete brand new hotend end along with motor and all printed parts, also 5 different PEI sheets, thermistors, heater cartriges, belts etc.

Original MK3S+ with BMG (Bondtech) will stay as is - MMU2S is waiting for this one, and Bear is going to be for hobby projects etc.

So after doing math I can build one with not too high cost and it's going to be upgradable in future.

What about plates to make this frame even more sturdy - https://www.aliexpress.com/item/4000119135269.html?spm=a2g0o.productlist.0.0.51b1544ewvMT8G&algo_pvid=b30e9af5-c68d-476e-93c0-30e3e8bf99c3&algo_exp_id=b30e9af5-c68d-476e-93c0-30e3e8bf99c3-0

I'll buy parts step by step, print what I need and work on this one in my free time.

These plates, in my opinion, are more for looks than stability.  The standard printer is plenty strong and stable.
