Cura 2.3 and USB - Startup Issue

[Wisar 86]

Can Cura be asked to NOT poll printers on the USB bus when it is started? It looks like this could be done by deleting the USB Plugin but then I would not be able to upgrade the firmware on the printer.

It is very irritating to have a print that is running from an SD card interrupted just because I have the audacity to launch Cura!

Thanks,

Will

Another workaround is not having your USB cable plugged in all the time. Only plug it in when you need it.

Alternatively you can use USB hubs with ON/OFF switches. Eg. https://www.amazon.com/Generic-7-Port-USB-Hub-Port/dp/B007S642BW

The printer in question doubles as a laser embosser / cutter and needs to be online for significant periods of time...I am actually more willing to disable the USB functionality on the Cura side but have not found the location of the plugins on OSX. Nor do I know if I can simply whack that particular plugin!

Right-click on the Cura icon in the finder and choose "show package contents".

Under Resources | Plugins | Plugins there is a USBPrinting folder. I assume it is that.

What printer do you have?

Well then...thanks for the pointer. Don't I feel stupid! Have no excuse for not finding it there myself.

Just moved the USB plugin out of that directory and no more issue. Can easily move it back when I am done tinkering (unlikely) or need to update firmware (even more unlikely as I run a slightly modified version of Tinker and load it from the Arduino IDE)!

I have a UM2 and a UM3. The UM2 hosts a laser from JTechPhotonics and very soon the plan is for it to also become a CNC Drill Press for putting holes in the circuit boards the laser etches. It also does 3D Printing of course!
