Co., Ltd. This isn’t a bad thing, just kind of a misleading
name game. In fact, there isn’t a single STARTT or iMakr
label located anywhere on the printer I received. On the
other hand, as shown in Figure 2, the printer and
electronics are sprinkled with TronXY branding throughout.
I found that supplementing the iMakr documentation
with various TronXY tidbits that can be found online helped
with the assembly. Try using your favorite search engine
and looking on the Thingiverse and GitHub websites. You
might find something helpful.
In all, it took me about four hours to build the STARTT
3D printer. Oddly enough, the greatest time waster is
removing all the protective release paper from the acrylic
parts. This paper removal is especially tedious on the
factory-assembled components like the hot-end assembly.
All the parts are very well made, however, and the fit is
While iMakr is quick to point out that a “complete” set
of tools is included with the STARTT 3D printer kit, two of
these parts are a pair of optimistically labeled “3D spanner
wrenches.” Theoretically, you would use these wrenches for
tightening various fasteners. In reality, you’re going to need
a quality adjustable wrench for performing this task (see
The fact that you need this additional tool isn’t an
indication of poor kit quality. It’s just the opposite. This kit
is able to tolerate the kind of precision adjustment that a
quality wrench can provide for making the printer into a
very potent performer.
I was truly surprised by the assembly and subsequent
performance of this kit. Upon completion of assembly,
there were only four minor “gotchas” that are worth
mentioning. First, I ran short of M3 x 20 mm fasteners. I
needed two extra screws for completing the kit.
Similarly, there were two different points where I
needed to add extra M3 washers to the assembly. First, the
Y axis motor needed four washers for tightening the mount
(see Figure 4). There was just a slight wobble without the
washers. The extra washers made the whole mount rock
The second point where I had to add a washer was
with the extruder motor. This motor mount was a factory-assembled piece and one threaded hole for receiving an M3
screw wasn’t tapped deep enough. I just added a washer
and the extruder motor mount was securely attached to the
printer side piece.
The fourth and final assembly problem I encountered
was the incorrect orientation of one of the Z axis threaded
rods. This fault was my installation mistake. There is a

Figure 3. Now this is a real wrench! You’ll need one for tightening up all of the printer’s fasteners.
