Hi, I just finished assembling the LEAD 1010 CNC and my laptop won't connect to xPRO v4. The laptop is connected via USB and I grabbed the latest Openbuilds Control. When I turn the power supply on router light turns on, double checked wiring, steppers engage. When I try to connect to control it says "PORT ERROR: Opening null: file not found" (see screenshot). Thanks, davabran laptop: surface pro 3 LEAD 1010, xPRO v4, nema 23 steppers, & 24V ps
Download the Arduino IDE software at Arduino - Software and install it. This will install the USB driver.
Instead of the whole arduino package, you really dont need. Just grab the correct FDTI VCP drivers here: Virtual COM Port Drivers
Ok installed the Arduino software and then the port drivers without initial success. I had to manually update the drivers in the device manager to get it updated. Now it works! Thanks for everyone's suggestions. I look forward hanging around this forum.
