Machine Operations
Symptom
Possible Cause
Possible Solution
Inconsistent cutting
depth.
1. Loose cutter.
2. Spoilboard not flat.
3. Z-axis ball screw has too much movement.
4. Workpiece loose.
5. Z-axis limit switch at fault.
6. CAM/G-code at fault.
1. Tighten spindle collet (
Page 25).
2. Clean/resurface spoilboard (
Page 26).
3. Inspect/tighten/replace if needed.
4. Secure workpiece with clamps (
Page 26).
5. Test/replace.
6. Review G-code and correct errors.
Machine fails to
home, or moves
beyond soft limits
when homing.
1. Incorrect machine parameters.
2. Faulty connection.
3. Limit switch not aligned.
4. Loose limit switch wire.
5. Limit switch at fault.
6. Circuit board at fault.
7. 50-pin data cable at fault.
1. Verify machine parameters (
Page 22).
2. Find/secure connection.
3. Inspect/adjust.
4. Secure connection.
5. Inspect/replace if needed.
6. Inspect/replace if needed.
7. Replace cable.
Display shows "out
of soft limits error".
1. Toolpath outside of working envelope.
2. Toolpath too large for working envelope.
3. Work origin incorrect in G-code.
4. Incorrect machine parameters.
5. Incorrect coordinate system in CAM
software.
1. Reset work origin and secure workpiece so toolpath
falls within working envelope.
2. Revise toolpath/break up toolpath into multiple
sections.
3. Revise toolpath.
4. Verify machine parameters (
Page 22).
5. Set correct coordinates in CAM software.
Controller not
processing
correctly.
1. Incompatible file.
2. Electrical interference.
3. Incorrect machine parameters.
1. Reformat G-code and re-upload to controller.
2. Retrace wiring and isolate the strong from the weak
electrical currents and the ground.
3. Verify machine parameters (
Page 22).
Finished workpiece
incorrect size.
1. Pulse equivalent incorrect.
2. Incorrect cutter.
1. Verify controller parameters and update pulse
equivalent (
Page 22).
2. Use correct cutter for job.
Spindle moves in
opposite direction
when homing.
1. Faulty connection between limit switch and
circuit board.
2. Homing direction set incorrectly in
controller.
3. Limit switch at fault.
4. Electrical interference triggering limit
switch.
5. Circuit board at fault.
6. 50-pin data cable at fault.
1. Retrace wiring to determine where bad connection
is located.
2. Input correct homing parameters (
Page 22).
3. Replace.
4. Reset circuit.
5. Replace.
6. Replace.
Axis will not
move after
controller receives
commands.
1. One axis not moving.
2. All axes not moving.
1. Check connection to motor. Check 50-pin
connection to circuit board.
2. Inspect 50-pin cable and circuit board connection
Inspect power supply to stepper motors. Inspect
mechanical components, such as ball screw
connections. Repair/replace as needed.
Axis movement
and location not
repeatable.
1. Ball screws worn.
2. Ball screw/motor coupler worn.
1. Inspect/repair.
2. Inspect/repair.
