Wisar 83 Posted November 22, 2016 in Cura 2.3 and USB - Startup Issue 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 Share this post Link to post Share on other sites
ahoeben 420 Posted November 22, 2016 in Cura 2.3 and USB - Startup Issue Another workaround is not having your USB cable plugged in all the time. Only plug it in when you need it. Share this post Link to post Share on other sites
thopiekar 8 Posted November 22, 2016 in Cura 2.3 and USB - Startup Issue Alternatively you can use USB hubs with ON/OFF switches. Eg. https://www.amazon.com/Generic-7-Port-USB-Hub-Port/dp/B007S642BW 1 Share this post Link to post Share on other sites
Wisar 83 Posted November 22, 2016 in Cura 2.3 and USB - Startup Issue 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! Share this post Link to post Share on other sites

Under Resources | Plugins | Plugins there is a USBPrinting folder. I assume it is that. What printer do you have? Share this post Link to post Share on other sites

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! Share this post Link to post Share on other sites
