Note

• For your safety, using T500 for any purpose other than 3d printing is not recommended, or the risks are on yourself.
• To ensure the best print quality, please don’t place T500 on a tilt or waggling platform.
• The shaking of the machine will affect the printing quality of the printer.
• Please do not place the machine near flammable and explosive materials or near high heat sources.
• Please place the machine in a ventilated, cool, and dust-free environment.
• It is recommended to use the material recommended by the manufacturer to avoid machine damage.

Settings

Network

1. Choose a Wifi connection
2. When there is “Connection” or after clicking close on the right bottom and back to the wifi interface, it shows “(connected)” after that wifi name, it means that is connecting successfully.
3. When it is “Connection” or after clicking close on the right bottom and back to the Wi-Fi interface, it shows “(connected)” after that wifi name, which means that is connecting successfully.
4. After entering the password, click save on the top right, not ☑on the right bottom.
5. The network PC/mobile /tablet needs to be under the same router as the network of printers so that they can connect remotely.

Bed Leveling

1. Click Move on the home page
2. Click Homing
3. Click Z Tilt. The machine will detect the left and right sides of the hotbed, and automatically calibrate the level of the X-axis beam
4. After machine calibration stops, Click More on the home page
5. Click Z calibrate. Please do not move a large distance at one time to avoid the nozzle hitting the hotbed.
6. Click start, the printer will auto-home first.
7. After the printer auto-home, the nozzle will slowly move to the center of the bed, put a piece of A4 paper between the nozzle and the hotbed.
8. Select the suitable move distance then click raise nozzle or lower nozzle , to adjust the distance between the nozzle and the hotbed.
9. Adjust the distance between the nozzle and the hotbed (please keep pulling the paper during the period, when you feel resistance to pulling the paper and the nozzle does not completely Press the paper, the distance is appropriate.
10. Click accept to apply the values, then confirm and restart the system.
11. Click More on the home page.
12. Click Bed Mesh, then click Calibrate after the detection is complete, restart the system, and Leveling complete. If you want to view the bed mesh data later, please return to this interface and click the current configuration name “default“ to view
13. It is recommended that you fine-tune the Z offset value again according to the actual situation when printing

The bed mesh data reflects the concave and convex of the hotbed. The detection data divides the hotbed into 25 small areas to detect the concave and convex. When 0 means flat, the positive value means relatively high, and the negative value means equivalent low. Which can reflect the level of the hotbed, The subsequent printer will adjust the offset value between the nozzle and the hotbed based on these data to compensate.

Change Configuration

1. If you want to change the printer configuration, after entering the web page by IP, click the “configuration” option on the left menu bar
2. Click the “Printer” file (the one without the date) to configure
3. After the configuration is complete, click the “SAVE & RESTART” option in the upper right corner (the clipper system will restart)

Load/unload filament

1. Click Extrude on the home page.
2. Then insert the filament into the extruder, and click load, the extruder will load the filament automatically if you need custom adjustment. click Extrude , Retract , Distance or Speed to adjust.
3. Each machine has been tested before leaving the factory, and it is normal to have residual filament in the nozzle.
4. When the nozzle temp is so low, it is not allowed to have related operations about the extruder. Please pre-heat nozzle first.

Print

1. You can remotely upload files on the web page and print, or directly insert a U disk into the USB port on the display to print.
2. Click “Print” on the main interface.
