Pressing information!
In this chapter you will need to pres some parts onto an another parts. You can found here some general information about these process:
- Usually, with correct 3D Printer calibration/settings the pressing can make with your hand.
- If the pressing can’t make with hand, use a Vise, or Hand Vise with our Pressing tools to press the parts together.
- You will found information in the assembly manual, that in which step, which Tool have to use and how.
4. If there is a gap between the pressed parts, you can increase the Flow [%] on your printer.
5. If it is too hard to press the parts together, you can decrease the Flow [%] on your printer.
