I cant believe ebay get away with this, but it is now full of "Prusa I3 Mk2S" 3d printers that are being shipped from China!! They are even using Prusa images on their info. One even has an image of the I3 Mk3 with lift off bed.

How can ebay get away with this?

Crazy

lol.... its open source so...it's a non-issue unless it's truly fake false-advertisement. i've seen an EXACT, EXACT clone from india. it was the same price though but the heat beds were identical/produced by them and milled powder coated frame etc.... same motors too. it was 100% proper clone with a mini-rambo. the markings on the steppers had their name and so the heat bed too but also gave credit to prusa on the bed. Course you wouldn't buy it from them since it was the same price but if you were local you would.

As i see they are all from https://www.millink.asia/en/millink-i3-mk2s/ . Looks like the power supply and the LCD Controller is even better than from Prusa. Would like to know if the quality is as good as prusa or even better, since they are using a quiet TMC2100 stepper driver motor.

Hi Diniar,
I can't see the item that you identify, on ebay...

there are a lot of what appear to be direct copies of the Pursa !3 with the 4 x 20 text lcd

anyway... returning to the one you linked to...
it seems to have a slightly larger build plate

did you look at the description of the power supply?

Meanwell Power Supply
High-quality Ming-wen power supply for a long time to stabilize the work, low heat, low noise temperature control fan.
I wonder if it's a copy of the meanwell design

or the Z axis... which uses universal coupled discrete leadscrews not integrated leadscrews... do they really mean almost Zero Backlash

POM Lead Screw Nut
With self-lubricating, quiet, almost zero slashback, easy handle 0.05mm layer height.

I guess it will appeal to some folk...

the TMC2130 are described as Pololu compatible, which suggests they are not integrated into the controller board.
and it doesn't say what the controller is...

I suspect they have rolled their own version of Marlin....

what bothers me, is that buyers of these copies might expect Prusa to provide them with support
and that they might expect this forum to be expert on their equipment...

regards Joan

They look bad. The images are stolen which is not right but the descriptions seem to promise a generic printer that is not associated to Josef Prusa.
