Failed Pumps comms

Likely that liquid is the issue. There is also a moisture sensor track half way down into the device (you can see if it you look into the top). Try a cotton bud with alcohol to wipe that. It has a lower surface too, so if that doesn’t work you would have to take two sides off to get at the underside. We strongly recommend using rubber O-rings in the lids to prevent any possible overflow so this doesn’t happen, since it is super annyoing!

I’ve done a thorough clean of all of the moisture sensors and I’m still getting the same error. I’ve changed the code in app.py to prevent the connection to ‘Pumps’ device and then it is successful in initializing the chibio, however when trying to switch on the devices online, only the red laser and heating appear to be working while the stirring and LED’s do not seem to work. Is there a workaround I could use in the code to prevent the moisture sensor issue? Right now I only need OD, heating, and stirring so if I could get those working that would be great. I’m still waiting to hear back from LabMaker to get help on this issue.

Hello,

If the heating is working then there LEDs/stirring should also work since they are controlled by the same PWM chip – that is, if the reason was to do with the digital communications.
So, if you see that some of those parts are working but not others it seems to point to some deeper hardware issue / fault in the device. Perhaps the 6V power regulator on the board is broken. I am afraid it is a challenge that you would need to get from Labmaker. Try emailing their support@labmaker address.
