error when playing with pump

[joihn]

Hello,

I have made a simple "learning mode" app, but when I play with the pump via uarm.set_pump(True), error appear on terminal (not always, 50% of the time).
the strangest thing is the the uarm itself continue moving, activating/deactivating pump without any problem...

Here is the log on my terminal:
