I'm having trouble with my 3D prints detaching from the printing surface before they're complete. What causes this and what are some ways I can prevent it from happening?

There are several causes:
1) Physical vibrations during the printing process, which can be caused by a poorly calibrated printer, unstable printing environment, or a machine in need of maintenance.
2) The corners of the print lifting off the bed due to uneven cooling, which can be caused by a lack of bed adhesion, an overheated bed, or an incorrectly calibrated extruder temperature.
3) Insufficient adhesion of the first layer to the print bed, which can be caused by an unclean bed, poor bed levelling, or incorrect bed temperature.
There might be and some other reasons. Let me know if I can help with something else.

I have also had difficulties with my 3D printer clogging. What may be the issue with it and some solutions?

The blockage can be caused by burning dirt or filament, especially with a small nozzle. Burning of dirt can happen in a dirty environment, such as a workshop where wood, stone or dust is swirling around. Therefore, make sure the printer is in a clean environment.

The filament itself can also burn. If the temperature of the nozzle is set too high, the material will burn instead of melt. This can happen, for example, when you want to print much faster. When the printing speed increases, the temperature should also go up. This way the material can flow through the nozzle fast enough. But be careful not to raise the temperature too high so that the filament does not burn away.

Sometimes the print head is not clogged with molten material, but with cold filament. This is also a matter of temperature, but in this case room temperature. If the printer is in a warm room, the material softens before it enters the print head. The extruder wheel that guides the filament through the print head will cause a dent in the material. This allows the material to bend and go back into the print head. Here it will pile up until there is no more room. I therefore recommend putting the printer in a conditioned area, such as the server room.
