The Y axis wires have been twist tied together here. The X and Z
axes are gently pulled out to see how long they are.
With the X axis moved ofer to one end, I can see that my bound
wires have enough slack so that they won’t be pulled on when the
carriage moves.
15. Connect the power supply, power cord, and USB cord between your
computer and the Stepoko
16. Open up the Universal Gcode Sender, open the Stepoko’s serial
port, and select the machine control tab. Set the switch to ‘ON’ and
try to move the machine by computer control. If the axis move in the
wrong directions to your liking (but of course, up should be positive
Z), switch the direction bit field accordingly. Use the Stepoko guide’s
Software: Machine Control section for more information about grbl, or
check out grbl’s Github wiki for more information on changing
settings.
17. Measure know movements and calibrate each axis. See the Stepoko
guide’s Firmware: Configuring grbl and Calibrating section for more
info.
Finishing Touches
The cable carriers have been included in your kit to help with wire
management, but it’s up to you to decide what cables to carry and where
you you would like them to be. They can go either way on an axis and don’t
need to be full length to get the job done.
This section shows the installation of a cable carrier between the mill head
and the cross-rail. The process is the same for any axis.
1. Start by finding the location and length of the cable carrier. Hold the
fixed end of the carrier in where you think it should go, and move the
mill head through the full range to make sure the cable carrier has
unrestrained motion along the axis of movement. Alternately, mimic
the motion of the mill to approximately check the motion. The cable
carrier should be shortened if there’s not enough play in the wires or
if the loop hangs too far off the mill.
