The Sapphire Plus from Two Trees a large coreXY 3D printer
Packed well but bad QC before Packing
After opening the box, I find that the printer is properly packaged and it has foam protection on all sides to ensure the package arrives safely. I had a damage stepper motor bracket and a slight off bed. (new parts are send)
Some Part allready assembled
The printer comes with some parts already assembled. The assembly took around 4.5 hours. The manual for the aseembly is very bad look for videos on the card or youtube.
DONT FORGET!!! to use lubrication on Z screws NOT INCLUDED.
I had to change my backlash nuts with some I laying arround. There was alot of backlash on the stock nuts and I did not want to go with them. After the change it did go very well and smooth.
This is a great fureture and works very well. It is a closed loop belt that ensure the Z motors are in sync. Now you have tro remeber to messure the distance in top and buttom on the rail if it is of like mine was then correct it before you start up your printer.
BMG long distance extruder
Sapphire Plus comes with BMG long distance extruder clone. I dont like that so I wil change that to a direct drive system instead.

Hotend is bad
Hotend is really bad it is made of aluminium, with the remote bowden system and I had alot of trouble with clog and extrusion.
Did test it and it was hard to get good prints in start with the hotend, so did the direct drive and that helped alot and now I get really good looking prints. I did notice the hotend cooling fan had some trouble and sometimes stopped I did replace it and did PID tunning and now it runs even better.
My Direct drive upgrade
build I did change the long distance bowden to direct drive from I did download from thingiverse.
I did improve my prints alot and the bad hotend just turn from bad to a okay hotend.
Design with a good frame
There’s a small 40mm fan that blows the air out of the printer. A fan blows over the stepper drivers. But all the fans are loud and 1 part cooler fan did fail after about 10 hours print and the fan that cool stepper driver are also going to get replaced it has started to make more noise. The PSU fan is very loud and that has to be replaced.
After sale support
Support from aftersale is very bad at first they ignore the problems I had with the printer.
After I did send video and pictures they did respond but not very well. The hotend problems I was told it was because I did not know how to use it. I did make a videos of it with my mobile. The Fans I was told that it was because I did not insure wires and filament not was in the way so it was also a user error.
After long time they did say that maybe they had to look at theese problems.
Coming up in upgrades
I will post a upgrade for this printer, it is a very simply upgrade but it makes the printer much better and print jobs easier and better.
It will change the printer from a average printer to a good printer and that is with the bad stock hotend.
The Printer out of the box works okay but needs to be check on VREF before use. After sale support is very bad. After some mods the printer is really good and I will recomend the you make a direct drive.
