CR20 Pro 3D Printer Guide Book

This guide book is for standard CR20 Pro.

Please plug the power cord into a three-hole power jack.

Detailed instructions for use are available on the TF card.

NOTES

1. Do not use the printer any way other than described herein in order to avoid

personal injury or property damage.

2. Do not place the printer near any heat source or flammable or explosive

objects. We suggest placing it in a well-ventilated, low-dust environment.

3. Do not expose the printer to violent vibration or any unstable environment, as

this may cause poor print quality.

4. Before using experimental or exotic filaments, we suggest using standard

filaments such as ABS or PLA to calibrate and test the machine.

5. Do not use any other power cable except the one supplied. Always use a

grounded three-prong power outlet.

6. Do not touch the nozzle or printing surface during operation as they may be

hot. Keep hands away from machine while in use to avoid burns or personal

injury.

7. Do not wear gloves or loose clothing when operating the printer. Such cloths

may become tangled in the printers moving parts leading to burns, possible

bodily injury, or printer damage.

8. When cleaning debris from the printer hotend, always use the provided tools.

Do not touch the nozzle directly when heated. This can cause personal injury.

9. Clean the printer frequently. Always turn the power off when cleaning, and

wipe with a dry cloth to remove dust, adhered printing plastics or any other

material off the frame, guide rails, or wheels . Use glass cleaner or

isopropyl alcohol to clean the print surface before every print for consistent

results.

10. Children under 10 years of age should not use the printer without supervision.
