CR-touch boot up the red light has been on since the end of the self-test
Cause: The self-test generates alarms, which are caused by two reasons.
1. CR-touch is not installed properly, which causes the probe to be deployed and stored for longer than the specified time;
2. CR-touch is affected by the firmware and outputs a long time high level when it is turned on, and the length of time that CR-touch outputs high level cannot be controlled.
Verification methods.
1. Pull the probe by hand, then release it and let the probe retract automatically to observe whether there is a sense of blockage.
2. Send the release alarm command "M280 P x S160" or click the "BL-touch reset" button to see if the red light turns into a colored light. If it doesn't turn into a color light, it means CR-touch is broken.
3. Perform a single "deploy probe" and "store probe" to see if each of them will be alarmed. If there is no alarm, it means that CR-touch is affected by the firmware.
Solution: For the case of not installed, you can disassemble the CR-touch and flatten the chip by yourself. For the case that the firmware is affected, please find a specialized after-sales service to deal with it.
When CR-touch stores the probe, the probe retracts successfully, but the red light stays on
Reason: The alarm is generated by the self-test. The reason for the alarm is that the CR-touch is not installed properly, which causes the probe to be stored for longer than the specified time;
Verification method: Use your hand to pull the probe, then release it and let the probe retract automatically to observe whether there is a sense of obstruction.
Solution: For this case of no installation, you can disassemble the CR-touch to flatten the chip by yourself.
CR-touch deploys the probe when the probe stretches out successfully or slowly, and then the red light stays on
Reason: The alarm is generated by the self-test, the reason for the alarm is that the CR-touch is not installed properly, which causes the probe deployment time to exceed the specified time;
Exclusion method: Pull the probe by hand and observe whether there is a sense of obstruction.
Solution: For this situation that is not installed well, you can disassemble the CR-touch yourself to flatten the chip.
