| Alarm Code | Message | Description | Example |
|---|---|---|---|
| 1 | Hard limit | Hard limit has been triggered. Machine position is likely lost due to sudden halt. Re-homing is highly recommended. | Example |
| 2 | Soft limit | Soft limit alarm. G-code motion target exceeds machine travel. Machine position retained. Alarm may be safely unlocked. | Example |
| 3 | Abort during cycle | Reset while in motion. Machine position is likely lost due to sudden halt. Re-homing is highly recommended. May be due to issuing g-code commands that exceed the limit of the machine. | |
| 4 | Probe fail | Probe fail. Probe is not in the expected initial state before starting probe cycle when G38.2 and G38.3 is not triggered and G38.4 and G38.5 is triggered. Your bit is likely making contact with the touch plate or the circuit is completed before the bit is moving. Move the bit away from the touch plate. | Example |
| 5 | Probe fail | Probe fail. Probe did not contact the workpiece within the programmed travel for G38.2 and G38.4. Your bit is too far away from the touch plate. Move the bit closer, it should be within 6-12mm (1/4 -1/2in) away. | Example |
| 6 | Homing fail | Homing fail. The active homing cycle was reset. | |
| 7 | Homing fail | Homing fail. Safety door was opened during homing cycle. | |
| 8 | Homing fail | Homing fail. Pull off travel failed to clear limit switch. The machine is within the limit switches range when it tries to move away. Try increasing pull-off setting or check wiring. | Example |
| 9 | Homing fail | Homing fail. Could not find limit switch within search distances. Try increasing max travel, decreasing pull-off distance, or check wiring. The limit switch wasn’t triggered in the distances expected. If your z-axis is moving away from the switch when homing, check your firmware and confirm you have the correct profile for your machine. | Example |
| 10 | E-stop asserted | E-stop asserted. Clear and reset. Untwist your E-stop. | |
| 11 | Homing required | Homing required. Execute homing command ($H) to continue. Your machine can’t start up until you first Home. | |
| 12 | Limit switch engaged | Limit switch engaged. Clear before continuing. A limit switch is on or off when it’s not supposed to, check if you’ve triggered them accidentally or you set them up the wrong way. | |
| 13 | Probe protection | Probe protection triggered. Clear before continuing. | |
| 14 | SaS timeout | Spindle at speed timeout. Clear before continuing. The spindle couldn't get up to speed in the time set for 'spindle at speed' or the spindle was wired or programmed incorrectly. The VFD may not be sending back correct signals to the board. | |
| 15 | Homing fail | Homing fail. Could not find second limit switch for auto squared axis within search distances. Try increasing max travel, decreasing pull-off distance, or check wiring. | |
| 16 | Selftest failed | Power on selftest (POS) failed. | |
| 17 | Motor fault | Motor fault. Issue encountered with closed loop motor tracking. Position likely lost. | |
| 18 | Homing fail | Homing fail. Bad configuration. |
