Zonestar P802QR2 Double Extruders 3D Printer DIY Kit

Autolevel seems very important as aluminium bed is not perfectly flat.
Stainless metal frame provide establility and durability, only z sliders are 3d printed.
Dual extruders for the price of one ;)
Issues from P802Q R1 fixed.
Look for reviews on forums and youtube, there is a lot of good stuff to check.
Good documentation for newbies (assembly, calibation and slicing).
Zonestar support returned my fist e-mail in 7 days (including weekend) and he reply the folowing e-mails in 24 hours max. Nicely and helpfull.

Suggestion

Z Slides was not very nicely printed, it is a little curved and I cracked when I mount, I had to keep only one screw in the the cooper nut with to avoid stuck the stepper. But you can easily print the replacments as zonestar provide all STL files.
Linear bearing seem noisely, I'm considering to try an good clean up or replace it.
For the price, the cons is not so impressive as for most of 3d printer kits

- CHEAP!
- metal frame --> no melting from whatever
- newest heating bed (MK3, Alu)
- Prusa i3 clone --> huge community
- solid machine, if you assemble everything correctly you got a nice and stable printer

Suggestion

- AC Adaptor: cable directly above power switch
- reachability of ZRIB- (control-) Board is´nt that good so for the first tweaks after assembly you need
small, long and powerful fingers...
- included auto leveling sensor is not good... (but maybe im just too unexperienced)

ALL THESE CONS ARE REALLY SMALL! If you keep thinking and trying you´ll fix all that problems.

Very good overall 3D printer. The dual extruder makes it convenient for printing soluble support. The metal frame makes the printer stronger (and better looking in my opinion). The SD Card is easily accessible from the back of the LED display panel instead of being on the mother board like most other 3D printers.

Suggestion

The Extrudes were particularity hard to assemble. It took me a while to have them properly extrude the material. The problem is that the spring they give you is often too small, therefore you need to take some pliers and stretch it as much as you can in order for them to give the proper "push" to the extruder lower part.

Also, on a minor point, the two material roll brackets are meant for 500g rolls. The majority of 1kg rolls will be too wide and too heavy for the brackets.

-Build quality is very good, holes line up on the stainless steel frame had no problems with assembling.

-A lot of extra screws after assembly that can be used for upgrades.

-Some extra wires included

-print quality is very good and the printer is easy to use

-accuracy is very good

Suggestion

-struggled quite a bit as my stepper motor controllers started overhearing when I started, a cooling fan needed to be added to cool the motherboard and controllers

- on off switch needs to be moved, not a big problem as it was quite easy to make my own design and designs are available on thingiverse.

- temperature control on the nozzle far away from the cooling fan is a bit of a problem that I still need to solve.

A good introduction to dual extruder printers with a straight forward build process.
The price is pretty good for a dual extruder printer kit.
Support was good from Zonestar when I had issues.
Issues were fixed relatively easily

Suggestion

Build plate wasn't flat and although Zonestar's support show you how to fix it (which was adding layers of tape), I ended up putting an Anycubic Ultrabase on mine.
One of the X-axis rods was too loose a fit.
While the frame is all metal, it requires bracing to make it sturdy.
The stepper drivers needed tweaking with a multimeter to reduce the factory set voltage as they were too high and overheated causing movement errors.

good value
seperate temperatures for each hot end
metal frame
well packaged
after tuning can print quite well

Suggestion

unclear build instructions
faulty parts. y-axis bracket
drivers where not set to proper voltage
needed much work to print properly
linear bearings need lubrication
some rods were warped

This is the first 3d printer I bought and I am very happy. I have had this printer now for 6 months and it is still going strong.

Works well but requires some time to learn how to use.
I would recommend this product only to people able to tackle with technical matters
Note : The manual recommends to use Repetier as a slicer, but I got good results with Cura

I like the price, assembly is a few hours, the printer gets good results with only minor tweaking.
