Windows 8.1 comes with Makerware Services pre-installed. Makerware will cause errors when running simultaneously with 3DPrinterOS. You should be prompted with a message saying “Running Makerbot conveyor service detected. You must kill it to continue using Client.”
Selecting the KILL button which will stop Makerwares background services. In addition, we also recommend manually ending the task by pressing “CTL + ALT + DEL” and ending the task in your task manager.
NOTE: This button simply closes Makerware services and will not have any harmful effects to Makerware or your computer.
