Troubleshooting

Issue:

The spindle is not releasing the tool holder when changing tools.

Resolution:

The spindle manufacturer recommends that the spindle not be left holding a tool

overnight or for any extended period of time; leaving a tool in overnight may cause the tool holder
to “stick” in the spindle. Use the 17mm wrench to apply pressure and push the tool holder out if this
occurs. Also, confirm that the regulator on your filter/regulator unit is set to supply 100psi to your
tool; inadequate are pressure can prevent the spindle’s draw bar from opening completely when
trying to drop off a tool.

Issue:

The tool is not aligning the tool holders with the tool clips when dropping off or picking up

bits.

Resolution:

Re-calibrate your tool clip locations using the calibration routine covered in the

“Calibrating ATC” section of this document.

Issue:

Depth of cut is inconsistent between bits.

Resolution:

Re-

measure your bit length using the “CN72” routine referenced in the “Zero Tools in

Rack” section of this document.

Issue:

The tool is not cutting in the correct location.

Resolution:

The default “origin” point for cuts designed in v-carve is the bottom, left hand corner of the cut

area. Be sure to run the C3 “homing” routine before starting a cut in order to align the tool to this origin
location. The JH (Jog Home) command can be used to send the tool to its origin.

Issue

: The tool was cutting fine but suddenly started cutting in the wrong place part-way through a cut

Resolution:

If the tool is unable to complete a motion either due to an obstacle (ex. hard metal fixture) or

being driven at excessive sp

eed (ex. 10 inches per second at full depth in ¾” plywood) it will lose its

reference position and need to be re-homed using the C3 routine. This does no damage to the motors on the
tool, however the motors will not be able to recover their correct position.

If in doubt
