12.7 Wiring
If your motor wires should become disconnected at some point, the correct wire
order is as follows: Left motor: “Motor 2” locations, yellow, red, green, gray (from
top to bottom). Right motor: Motor 1 (same order). Servo cable: B1 (lowest three
pins on left hand side), with black wire towards the edge of the board. Refer also
to the illustrations in section “2.3 Unboxing AxiDraw” on page 12.
12.8 The pen-lift servo motor
The only expendable component of the AxiDraw is the small, blue pen-lift servo
motor. They do wear out over time but are inexpensive and straightforward to re-
place. For heavy duty applications, you may wish to keep a spare on hand. Spares
are available at https://emsl.us/902 and through select resellers.
If you are setting up an AxiDraw for the first time and the pen-lift motor does
not appear to be operating, double-check that you have connected the cable
correctly, following along with §2.3 Unboxing AxiDraw, on page 12.
12.9 Loss of position
The most significant thing that can go wrong under normal operation is a loss
of position control while the carriage is moving. This is typically manifested as a
loud grinding or screeching noise. It can happen when moving at too high of a
speed, or when the carriage hits an unexpected obstacle– for example if it was
not moved to the Home Corner before plotting or if it was bumped while moving.
If this should happen, press the pause button as soon as possible to cancel the
plot. Remove power to the machine if necessary. Use Raise pen, turn o motors
in the setup tab to de-energize the motors, and manually return the carriage to
the Home Corner before trying to plot again. As a sanity check, the carriage
should return exactly to the Home Corner when a plot is finished.
12.10 Service, repair, and parts support
The AxiDraw is designed to be serviceable, and we are here to help. Nothing
should require regular replacement. However, most parts of the machine can be
unscrewed and replaced if necessary. Please contact technical support directly if
you need assistance with troubleshooting or repairing a mechanical issue.
