myCobot 280 M5Stack - Issues with Suction Pump and Basic Pin 5

[kkluiae]

As suction pump is correctly connected to the base of robotic arm, when you set basic pin 5 to mode 0 (meaning that the suction pump is turned ON), there is a chance that myCobot would reboot, resulting in forced exit of currently running programs in the robotic arm

The following code is to turn on the suction pump:

mc = MyCobotSocket(ip,port) #  or mc = MyCobot(com_port,baudrate)
time.sleep(1)
mc.set_basic_pin(5,0)

Note that no matter the code, as long as you set the basic pin 5 mode to 0, there is a chance to reboot myCobot

’m facing the same issue. Is there any update on this? I can't turn off the pump—when I set pin 5 to HIGH, it resets back to LOW, turning the pump back on.

I tested the output with a voltmeter, and when I set pin 5 to HIGH, it briefly goes up to 3.3V but then drops back to 0V.
