Cura macOS usb freezes board #130

Hi everyone,

Got my E3 v1.2 up and running and have noticed that when plugged in to the usb and running Cura, i get a high pitched siren sound from my z stepper and the board freezes up. When connected to Simplify3d no problem and is as silent as a mouse and prints fine. When I complied marlin (this BTT fork) I used 0.6.1 tmc library. Any ideas what could be the problem? I'm recompiling now with 0.5.2 to see if that helps Also compiled 512k nousb

So I found a work around with the help of one of the FB group members.

In Cura autodetectbaudjob.py, if you comment out

try:

programmer.connect(self._serial_port)

serial = programmer.leaveISP()

except ispBase.IspError:

programmer.close()

Then it stops making the siren sound but it still freezes the board and you need to power off and disconnect the usb to get it back. As it stands, I cannot use Cura connected to usb or even start cura for that matter with usb connected

Here is the issue on the cura website

Here is the exact fix for the e3 mini 1.2

programmer = Stk500v2() comment serial = None do not comment try: programmer.connect(self._serialport) comment serial = programmer.leaveISP() comment except ispBase.IspError: comment programmer.close() comment_
