Frequently Asked Questions - CR20 Pro CREALITY
How do I level the print bed on the CR20 Pro?
Use the paper method: Home all axes, then manually adjust the four bed knobs until a sheet of paper slides with slight resistance between the nozzle and the bed. Repeat for all corners.
What filament types can I use with the CR20 Pro?
The CR20 Pro supports PLA, ABS, PETG, and TPU. Ensure the filament diameter is 1.75 mm and adjust temperature settings accordingly.
Why is the first layer not sticking to the bed?
Check bed leveling, clean the bed with isopropyl alcohol, ensure bed temperature is correct (60°C for PLA, 80-100°C for ABS), and adjust the Z-offset if necessary.
How do I change the filament on the CR20 Pro?
Preheat the hotend to filament temperature, use the 'Filament Change' menu to unload old filament by retracting, then insert new filament and push until extruded. Clean any oozing material.
What should I do if the printer stops mid-print?
Check if the SD card is properly inserted, ensure power is stable, and look for filament jams. If the printer has power loss recovery, it should resume automatically.
How do I update the firmware on the CR20 Pro?
Download the latest firmware from Creality's website, copy it to an SD card (FAT32), insert the card, and navigate to 'Update Firmware' in the settings. Do not power off during update.
What replacement parts are commonly needed?
Commonly replaced parts include nozzles, PTFE tubes, build plate, and extruder gears. These are widely available from Creality or third-party sellers.
How do I clean the hotend if it gets clogged?
Heat the hotend to 240°C, use the included cleaning needle to push through the nozzle while extruding briefly. Alternatively, do a 'cold pull' with PLA filament to remove debris.
Is the CR20 Pro safe to leave unattended?
It includes thermal runaway protection and a filament runout sensor, but always follow manufacturer guidelines. Never leave it unattended for extended periods without supervision.
How do I adjust the print speed and quality?
In your slicer software (like Cura), adjust speed (typically 50-60 mm/s), layer height (0.2 mm for quality, 0.3 mm for speed), and infill percentage. Always run a test print first.
