Module13.2 GRBL

Example

The GRBL module drives the three axes to perform periodic reciprocating motion in the distance mode

from m5stack import *
from m5ui import *
from uiflow import *
import module

import time

setScreenColor(0x222222)
grbl = module.get(module.GRBL)

grbl.set_mode("distance")
while True:
  grbl.turn(10, 10, 10, 100)
  wait(5)
  grbl.turn((-10), (-10), (-10), 100)
  wait(5)
  wait_ms(2)

API

grbl.set_mode("distance")

• Setting the GRBL operating mode:
  • distance:Distance control mode
  • absolute:Absolute position control mode

grbl.turn(10, 10, 10, speed)

• In distance control mode, the stepper motor is controlled to move a specified distance.

grbl.g_code('')

• Send GRBL G-code for control.
  • See GRBL - Github for the contents of the directive

grbl.wait_idle()

• Blocking waiting for the motor to stop running

grbl.in_lock()

• Determines whether the motor is in a locked state.

grbl.lock_motor()

• Locking at the end of motor operation

grbl.read_idle()

• Determine whether the motor is idle or not

grbl.read_line()

• Read GRBL control return information

grbl.unlock()

• Unlock motor lock state after limit trigger

grbl.unlock_motor()

• No locking after the motor has finished running

grbl.read_clean()

• Clear GRBL return data message
