i have been having problems with layer shifting on my tevo tornado. since im new to 3d printing i have no idea what to do about it. i did some research on what could be causing it but everything that i think might be causing it should not be the problem. i set the drivers to .99 volts and the layer shifting improved a little. on the tevo tornado group on thingiverse someone suggested adjusting the acceleration to about 3000 so i did. the problem with that is that whenever i try to print, the acceleration goes back to 500 even when i have saved the settings. could it be that i just have a bad control board?

Doesn't tevo provide support?
