Possible Solution
1. Verify controller parameters and update pulse
equivalent (Page 23).
2. Use correct cutter for job.
3. Correct CAD/CAM errors as needed.
1. Test wiring to locate bad connection.
2. Input correct homing parameters (Page 23).
3. Test (Page 45)/replace limit switch.
4. Test wiring and isolate strong interference signals
from electrical currents and ground.
5. Replace interface board.
6. Replace 50-pin data cable.
Possible Solution
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 23).
5. Set correct coordinates in CAM software.
1. Reformat G-code and re-upload to controller.
2. Test wiring and isolate strong interference signals
from electrical currents and ground.
3. Verify machine parameters (Page 23).
4. Use compatible post-processor. In V-Carve, select
"RichAuto A11 DSP" from the drop-down menu.
1. Inspect/replace power supply.
2. Use correct power supply. High voltage may
damage controller; replace if needed.
3. Inspect/clean plugs and sockets and retry. Replace
if bad.
4. Replace controller.
1. Inspect/clean plugs and sockets and retry. Replace
if faulty.
2. Ensure correct power supply voltage and circuit
size.
3. Update controller software (Page 46).
4. Replace controller.
1. Rewire interface board.
