Switching of the auto connect to printer

[Rebekah_harper]

Hiya all,

I just managed to kill off 23hrs of a 27hr print by just opening S3D.

I use both SD card and USB depending on the length of print and what the aim of the print is.

I don't want to disconnect the cable each time (as it's not often I find my self in this position)

The auto connect caused the printer to stop dead.

Is there a way for the auto connect to printer to be turned off and that it always requires me to click connect in order to establish connection .

cheers

Becky

PS: I have finished crying now lol

Tools > Options, then check the "disable automatic USB device detection" option

Simplify3D just killed a beautiful 47 hour print because I opened it up w/ USB connected from a firmware update a few days ago. Now I also have to buy new filament before I can complete my print. My print is not the only one Simplify3D killed. I see people migrating away from printing via USB so why is it on in Simplify3D by default?
