Hello all,

I just bought an Ender 5 pro; when I turned it on, it said TMC connection error, so I tried updating the firmware, now the error message is gone, but the machine makes a long beeping sound and won't stop.

Any help will be appreciated.

Thanks!

I had the same issue too, but I tried installing the firmware, and the TMC error disappeared, but now when I turn on the machine, it makes a long beeping sound that won't go away. Any help will be appreciated.
