BlTouch randomly deploys probe twice.
-
Would a bad or shorted heatbed cause something like nthis or do you have any ideas on what would cause this to happen.I know it could have been a bad regulator to start with but it seems weird that it worked fine for a few weeks and just suddenly stopped working?
-
No, a faulty heat bed might damage the bed heater mosfet but it shouldn't affect the 5V regulator. OTOH if you connected external devices to +5V then a prolonged overload might damage it.
-
The only thing that changed was I installed a larger bed. I don't have any extra items connected to the board other than the necessary items to operate the printer.
-
I do not know if this is the case, but I had this happenning to me a few months ago.
I found out that my BLTouch wire were damaged. The BLTouch would "reset" and deploys like when turned on.
IMO, you might have a damaged wire or possibly problem with your connectors.
I hope this helps.

I will check again to make sure but was your BlTouch working while it was doing this? Mine keeps working just fine while it is doing this. I do get quite a few the probe was triggered before move messages.
