GCODES FOR X ENCODER

Identity X Encoder

To identify whether the COM port is associated with the X Encoder, send the command IsXEncoder. If it is indeed linked to the X Encoder, it will respond with YesXEncoder.

For Eg:

IsXEncoder

>>> YesXEncoder

M316 - Select Response Mode

Description

There are 2 types of response modes: Absolute Mode and Relative Mode. In ABSOLUTE MODE, all responsed positions relative to the origin location. With RELATIVE MODE, reponsed positions relative to the previous position.

Usage

M316 [<mode>]

Parameter

[mode]: mode index

  • 0: Absolute Mode (default)
  • 1: Relative Mode

Example

M316 1   ;relative mode

M317 - Get Current Position

Description

Get current position (mm) in current mode. You can also set a feedback cycle time to auto response current position.

Usage

M317
M317 [T<period>]

Parameter

  • M317 : return current position
  • M317 T[period]: auto feedback position in every period miliseconds.

Example

M317   ;get current position
>>> P:13.2    ;current pos is 13.2 mm

M317 T200    ;set auto feedback position every 200ms
>>> P:14.5
>>> P:21.2
>>> P:27.5

M318 - Set Pulse/MM value

Description

When you need to calibrate the encoder, you can change the pul/mm parameter to exactly what you have checked. Default is 5.12 pulse/mm.

Usage

M318 [S<value>]

Parameter

S[value] : pulse per mm value

Example

M318 S1.0    ;now you can get the origin pulse by M317

M319 - Read Proximity Sensor

Description

X Encoder have a 3-pin GX jack to plug proximity in. This command help you read the sensor status right away or auto response status when it have changed.

Usage

M319 V
M319 T

Parameter

  • M319 V : get current sensor value
  • M319 T : set auto feedback when the sensor value changed
