beginJog()

Posted by On 10 / 03 / 2019 0 Comment

Describe

Enable Jog mode. In this mode, the Machine cannot perform other motion control. It can only use the pull-down switch connected outside the specified pin to perform control.
In Jog mode, the following two control behaviors are distinguished:
Jog Mode – After pressing the switch (pull down), starts moving until it stops after pulling up.
incJog Mode – Click the switch to move a unit distance, and you can set the distance using setJogOffset().

Grammar

machine.beginJog(pX, mX, pY, mY, pZ, mZ);
machine.beginJog(pX, mX, pY, mY, pZ, mZ, incJog);

Parameter

machine: It is an object of Machine. 

pX: Pin foot position corresponding to the positive direction of the X-axis (plus). 

mX: Pin foot position corresponding to the negative direction of the X-axis (minus). 

pY: Pin foot position corresponding to the positive direction of the Y axis (plus). 

mY: Pin foot position corresponding to the negative direction of the Y axis (minus). 

pZ: Pin foot position corresponding to the positive direction of the Z axis (plus). 

mZ: Pin foot position corresponding to the negative direction of the Z axis (minus). 

incJog: Whether to enable incJog mode, preset to false. .

Return

No return value.

Example

Sets the basic parameters of the machine and enables Jog mode to move when the button is triggered.
