X-Axis Failures

The x-axis motion on the AMAYA is controlled through the electronics, a system of pulleys and a cable. The motor driver on the Main PCB will send certain commands to the X-axis servo motor. Feedback to the Main PCB is provided by the motor encoder and the X-home sensor. These devices tell the Main PCB where the motor is at during embroidering.

Problem	Possible Causes	Solution
Binding in x-axis or jumpy, uneven movement of the x-carriage	Improper Adjustment of x-carriage linear bearings	Adjust the radial bearings on the x-carriage assembly
	Lack of lubrication on the carriage rails in the x-beam	Lubricate the carriage rails
	Fretting corrosion of the x-rails	Replace the x-beam and the bearings on the carriage
	X-cable tension too high	Adjust x-cable tension
	Damaged x-cable	Replace the x-cable
	Damaged bearing(s)	Replace the radial bearings on top of the x-carriage
	Damaged pulley	Replace the damaged pulley.
Excess noise when carriage moves	Lack of lubrication to the carriage rails	Lubricate the carriage rails
	Improper adjustment of the x-carriage linear bearings	Adjust the linear bearings
	Cable tension too high	Adjust x-cable tension
	Fretting corrosion of the carriage rails	Replace the x-beam and the bearings on the carriage
X-axis runaway	Connection at motor encoder reversed	Reconnect the interface harness to the x-motor correctly
X-axis runaway	Short in either the x/y home harness or the motor interface cable	Replace the defective harness
Can not find home	X/Y Home Not Set message will appear in the AMAYA OS message text box	Set x/y home
	Dirty or damaged sensor	Clean or replace the x-home optical switch assembly.
	Loose harness connection	Reconnect the harness
