Flexi-HAL grblHAL Controller Package

AUD$175.00 (inc. 10% GST in AU)

Flexi-HAL board and 2x RJ45 breakout boards:

  • Sensor breakout (X, Y, Z, Y2/A, Probe, Limit. 12-24v powered)
  • Button breakout (Halt, Hold, Cycle/Start. 12-24v power for LED illuminated external buttons)

Compatible with the truly excellent Jog2K Keypad Pendant.

Seriously, if you don’t know about the Jog2K, have a look at the PrintNC Wiki page. I’ve had many customers come back to order one after receiving their Flexi-HAL or GRBLHAL2000 board. I think it’s the best bang-for-buck quality of life improvement to a grblHAL machine.
