proper orientation for the dual Z axis threaded rods. It’s
relatively easy to install the rods into the Z axis stepper
motor Z coupler and test the operation. If you can’t easily
rotate the Z coupler, then you have the threaded rod
installed upside down (see Figure 5). Just unthread the rod,
flip it over, and reattach it to the Z coupler. Now you should
be good to go.
The Proof is in the Print
No matter how well built a 3D printer is, the real test is
in its ability to accurately print a 3D model. Unfortunately,
the assembly guide kinda leaves you hanging with the final
calibration and print setup steps. At this point, you must
rely solely on the instructional videos. Luckily, these final
two videos in the STARTT 3D printer kit assembly video
series are very helpful and accurate.
You must calibrate your printer before you can print
(see Figure 6). You should use a prepared iMakr test model
for your first print. Thankfully, iMakr has both of these
bases covered. The entire calibration process is easy to
perform and functions as a good test drive of your
assembled printer. Remember, there is no ON/OFF switch,
so when you plug the power supply into the printer, it’ll be
ready to go.
No computer is required for operation. All 3D models
are prepared on a computer via the iMakr-supplied Cura
software (i.e., downloaded from the STARTT 3D Printer
Support page). Once these models are converted into
GCode, they are loaded onto a micro SD card (a card is
supplied with the STARTT 3D printer kit) which is then
inserted into the printer’s PCB (printed circuit board).
Everything regarding the operation of the printer is
controlled through the LCD and five-button interface (see
Figure 7. Temperature, build height, and completeness of the print are continuously updated on the LCD.
Figure 6. Perfect! Our level resting on the top of the X axis/ hot-end carriage. Figure 5. Turn this Z coupler for adjusting the Z axis. Unbelievably, for a kit priced under $100, there are two Z axis stepper motors. This is the left motor.
