uArm Controlling Method: uArm Studio and direct serial commands
I reported that the vacuum pump just stopped working about 2 weeks ago. Thanks for uArm Tech support they mailed me a new pump and cable. However, today after installing new pump, same symptoms:
i can send serial commands to enable/disable the pump (#1 M2231 V1/V0), and then read back the status using #1 P2231, and the status reports the desired status of the pump.
however the pump fails to turn on.
After reading a similar thread i am believeing that perhaps my main pcb board needs to be replaced. perhaps there is a drive circuit (transistor or power supply components) that need to be replaced. Based on the feedback of the status, i am guessing the digital signal to enalbe/disable is correct but the drive current is not being delivered to the pump.
