4.3 Testing
A.
To begin testing, disconnect from the CNC-xPro, and move the machine by hand so
that it is in the middle of it’s max travel on all axes.
B.
Switch on the 24V-360W-Power-Supply, and the 2 x 30mm-24V-DC-Fan’s should acti-
vate. If they do not activate, check the wiring in Step 3.0.4.
C.
Reconnect to the CNC-xPro in UGS. Next to each driver on the CNC-xPro, there is a
current control pot, and these can be adjusted using the Ceramic-Screwdriver. Rotate
clockwise to increase the current, and anti-clockwise to decrease. The default posi-
tions should work fine, but they can be adjusted to increase/decrease motor torque or
quiet motor motion. If in Step D below the motors don’t move, first check the wiring in
Step 4.1.3. If that isn’t the issue, then slightly increase the motor current in 1/8th
turns.
D.
Looking from the front of the machine, the correct axes machine motion is: X-Axis
positive to the right, Y-Axis positive going away, Z-Axis positive going up. To test this
in UGS, click on the ‘Machine Control’ tab on the top bar. On the right hand side there
are jog controls. Set the ‘Step size’ to 20 and select ‘millimeters’. Press the ‘X+’ but-
ton to jog the machine in the positive X direction, and the carriage should move to the
right. Press ‘Y+’ and the gantry should move away. Press ‘Z+’ the Z-Axis should go
up.
E.
If in Step C any of the axes have moved in the opposite directions than should be
expected, turn off machine and disconnect from the CNC-xPro. To correct this issue,
locate the motor wire for the axis that is incorrect and flip the wire colour order on the
CNC-xPro. Repeat Steps B, C & D to retest the machine.
F.
Once the motor directions are correct, use the jog controls in UGS to check that the
machine can move through the whole distance of its travels on all axes. If this is
unsuccessful, first check that the ACME-Lead-Screw are attached correctly, aligned,
and not binding. If the assembly is correct, it may be that the drivers on the CNC-xPro
are overheating, so try decreasing the current in 1/8th turns.
