Twotrees High Speed Printing Kit for 3D Printer SP-5

Great after sales service. I personally have had heating issues with two different suppliers of this product, but resolved here. Only depending on one's needs would question perhaps about different configuration of hotend or alternatives? Other wise not too bad, but service is great (don't be impatient)😊

1) Instructions are minimal and could do with a lot more details . New hot end was initially installed back to front, this was found when trying to fit the limit switch.

2) One of the new idler pulley wheels was supplied with wrong bearing - 4.0mm hole not 5.0mm; old one re used. Not clear on why these have to be changed.

3) Front hot end cover needed to be modified to fit - as supplied it jammed on the slide rail.

4) Rear cover for the hot end would not fit, as no cut out to allow the cables to exit the hot end.

5) wire lengths fro the hot end cables some were too short, others too long.

6) Screen could do with a this way up on the protective film. Earth symbol is now in the opposite corner. all metal screws should be used, the nylon screw "to isolate static electricity" this is wrong, this corner is meant to be earthed, hence the symbol.

7) In particular, there needs to be a diagram of the connections to the new mother board, in particular for the screen. I eventually found the connection diagram at

8) The supply instructions also need to give the new parameters, especially speeds.

this kit was nice, but it still dont have temperature limit for hotend for 320C and hotbed 110C.i hope a backup firmware are profided.last time my home suddenly got blackout.at that time my printer currently running.when the blacout happen, my printer also power off.after my home power are back online, my printer doesnt show anything on screem.all blackut.i tried several times restart the printer.but no result.then i see someone on youtube show custom firmware(by russian) develope an interface for it.(it was call SHUI). for the temporary solution, im using that firmware. i had tried to compile msrlin firmware, but no luck.none is working.
i hope two trees can profide backup firmware with 350c hotend temperature setting and hotbed temperature 120C.
if youncan give me those firmware, im really appreciate it.

I'm very satisfied

Funziona tutto bene
