Pneumatic Gripper Intermittent Disconnect
Intermittent disconnect from PC (COM5). I’ve removed and checked the diode and it test OK. Polarity is correct. Resetting the HMI 5v IO Board Com Port back to COM5 works for a little while longer. Seems to always be on D0 off. New install - never worked correctly. MK3 HMI v6.3 Nano Sketch v1.3
