System and methods for configuring a reciprocating saw
First Claim
1. A hand-held power tool configured to implement a cut-stop feature, the hand-held power tool comprising:
- a housing;
a motor within the housing, wherein the motor includes a rotor and a stator;
a transmission coupled between the motor and a reciprocating spindle, wherein the transmission converts rotational motion of the motor to reciprocating motion of the reciprocating spindle;
a blade holder coupled to the reciprocating spindle;
a sensor configured to monitor a motor current;
a wireless communication controller configured to receive an instruction from an external device prior to driving the motor, wherein the instruction instructs the hand-held power tool to enable the cut-stop feature;
an electronic processor located within the housing of the hand-held power tool and coupled to the sensor and to the wireless communication controller, wherein the electronic processor is configured toreceive the instruction from the wireless communication controller, andenable the cut-stop feature of the hand-held power tool in response to receiving the instruction, wherein during implementation of the cut-stop feature the electronic processor is configured tostart driving the motor in response to determining that a trigger has been depressed,determine that an item is being cut based on the motor current exceeding a cutting threshold,determine that the item is no longer being cut based on the motor current decreasing below the cutting threshold, andin response to determining that the item is no longer being cut based on the motor current decreasing below the cutting threshold, cease driving the motor for avoiding cutting of another object proximate the hand-held power tool.

Abstract
Systems and methods for configuring a power tool. One system includes a power tool communication system that includes an external device and a power tool. The external device includes a user interface configured to receive a first selection to enable a feature of a power tool, and receive a second selection of a threshold of a motor characteristic of the power tool. The power tool includes a motor within a housing. The power tool receives the selected feature and the selected threshold from the external device. The power tool includes a sensor configured to monitor the motor characteristic of the motor. The power tool further includes an electronic processor that controls the motor to operate according to the selected feature and adjusts an operating parameter of the motor when the motor characteristic is determined to cross the selected threshold.

5. A hand-held power tool comprising:
-
a housing; a motor within the housing, wherein the motor includes a rotor and a stator; a transmission coupled between the motor and a reciprocating spindle, wherein the transmission converts rotational motion of the motor to reciprocating motion of the reciprocating spindle; a blade holder coupled to the reciprocating spindle; a sensor configured to monitor a motor current; a wireless communication controller configured to receive an instruction from an external device prior to driving the motor, wherein the instruction instructs the hand-held power tool to enable a blind-cut feature; an electronic processor located within the housing of the hand-held power tool and coupled to the sensor and to the wireless communication controller, wherein the electronic processor is configured to receive the instruction from the wireless communication controller, and enable the blind-cut feature in response to receiving the instruction, wherein during implementation of the blind-cut feature the electronic processor is configured to start driving the motor in response to determining that a trigger has been depressed, determine that a first material is being cut based on the motor current by detecting a first increase in a motor current acceleration that exceeds a first threshold, while the first material is being cut, monitor the motor current acceleration, determine that a second material is being cut based on the motor current acceleration by detecting a second increase in the motor current acceleration that exceeds a second threshold, and in response to determining that the second material is being cut by detecting the second increase in the motor current acceleration that exceeds the second threshold, cease driving the motor. - View Dependent Claims (6, 7, 8)
