The shorter PTFE tube is not a big problem. If the filament is properly fed into the PTFE tube without blocking the movement, it is fine. The problem could be with flexible filament - there we recommend
- Reduce the print speed - off 40% or more
- Reduce the press on the springs on hobbled pulleys.
The correct step - the last step to securely lock the PTFE tube is shown in the second figure. You have to push the PTFE tube all the way in - so that there is no gap inside the Hotend. Then push the PTFE tube inside while pulling the black collet up. By doing so, the PTFE tube is fixed and locked in place. It is therefore not meant to out the collet completely but only partially to fix the position of the PTFE tube. See the second figure.

The silver PSU is tested and of the same quality as the new black PSU. New PSUs will soon be delivered. If you received PSU silver, it is absolutely fine and you will not need a newer one. The type of PSU has no effect on the printer.
The bearings should move smoothly on the rods. A bit of scratching is normal. If the pressure on the bearings is greater during motion, try to check that the rods are not scratched or that the bearings are not damaged. If there is a problem with visible damage or rods / bearings are damaged, do not hesitate to contact our technical support on email: email@example.com.
