According to the ProTech TL4645 Low Cost Entry Level 3D Printer user manual, here are some troubleshooting steps to address the issue of prints not adhering to the print platform:

1. **Distance Between Printing Platform and Nozzle:** Ensure that the distance between the printing platform and the nozzle is appropriate. Adjust the four horizontal adjustment nuts under the platform to achieve the correct distance, which can be approximately the same as the thickness of a business card.

2. **Printing Platform Temperature:** Check if the printing platform temperature is set correctly. For PLA material, the temperature is typically set around 60ºC, while for ABS material, it is around 100ºC.

3. **Platform Cooling Fan:** If the platform cooling fan is turning on too early, adjust this setting in your slicer software to ensure proper adhesion.

4. **Extruder Gear Stuck:** If the filament will not load normally due to the extruder gear being stuck, ensure that the temperature is at the appropriate melting point for the filament. Adjust the temperature on the LCD screen if needed.

5. **Feeding Reel Issues:** Check if the feeding reel is knotted or if the filament is not feeding properly. If necessary, cut off the filament, adjust it, and try printing again.

6. **Nozzle and Filament Diameter:** Verify that the distance between the print platform and the nozzle is not too small, and ensure the correct filament diameter (1.75mm) is being used.

7. **Nozzle Condition:** If the nozzle is plugged or damaged, contact the place of purchase for assistance.

By following these troubleshooting steps, you should be able to address the issue of prints not adhering to the print platform with your ProTech TL4645 3D printer.
