Here's another 6 tips / tricks that could help you starting out printing with your X1-Carbon, P1P, P1PS and A1 / A1 mini.
1. First Layer Filament Sequence
2. Changing speeds on the fly - Silent, Standard, Sport and Ludicrous
3. What does Ludicrous look like? Probably not a good idea to use!!
4. Firmware update go wrong? Roll it back!
5. Arrange all objects - this is a simple one but something someone starting out may not realize.
6. Variable Layer Height - this is awesome to smooth out round spots that aren't coming out right!
