Re: Touchscreen calibration

Can you adjust the resolution on the monitor to 1366x768? I'd am curious to see if that affects the touch position.

Be careful with modifications to the RPi linux. It would be wise to make a backup copy of the sd card before making changes.

Re: Touchscreen calibration

Have you tried adjusting the resolution of the monitor? My ASUS VT168H runs at 1366 x 768 resolution. You can also try adjusting the sweep frequency. Available options are usually 50hz and 60hz.

Re: Losing Z

Do you have any holding current set on your z-axis? If so, how much?

As it turns out, I created a program called GCodeDebugger a while back and it provides the ability to set break points and step through the code. If you are interested...

What version of software are you running on your Buildbotcs Controller? Please list all of the devices that you have plu...

In looking at your log, it appears that the error occurred right after the avr rebooted.One of the things that 2.0.4 changed was to prevent the controller from getting damaged if the usb bus is overloaded during bootup. We found that if the usb bus is overloaded during bootup, it causes the attiny t...
