Please be advised: UPS Shipping will take more time to be shipped as packages need to be taken to a UPS store which is not done every day. Please select USPS for a faster shipping turnaround.
Make sure to watch my Mach3 USB outputs video on the product page for the Mach3 USB controller. If it still doesn't work, make sure to set the port to port 3 for the output you are using.
