!!! danger Maximum Temperature Resistance: 200 degrees Celsius / 392 degrees Fahrenheit !!! The H1H steel plate surface is resistant to temperatures up to 200°C. After extensive testing, we recommend the H1H for printing on PLA / PETG / ABS, if you want to print on other filaments, please adjust the parameters. **We recommend filament use temperature:** - PLA: 50-60 degrees Celsius / 122-140 degrees Fahrenheit in the heat bed and 220-230 degrees Celsius / 428-446 degrees Fahrenheit in the nozzle. - PETG: Heat bed temperature 80-90 degrees Celsius / 176-194 degrees Celsius, nozzle temperature 240-250 degrees Celsius / 464-482 degrees Celsius. - ABS: Hot bed temperature 90-100 degrees Celsius/194-212 degrees Celsius, nozzle temperature 250-270 degrees Celsius/482-518 degrees Celsius. **If the printer shows the following prompts during printing, please follow our guidelines to do so:** 1. The build plate localization marker is not detcted. Why this message appears: because the steel plate is a hologram, and the printer is localized by scanning, but does not affect the filament extrusion correction. Solution: Choose to ignore (make sure your printer has been correctly calibrated under the premise) and continue to print, and will not affect the print. 2. First layer inspection terminated due to abnormal Lidar data. Why this message appears: Because the steel plate is a hologram and the printer is scanning the first layer with Lidar, but it is not possible due to reflections. Solution: Choose to ignore it (make sure you see your first layer is intact) and continue printing, it will not affect the print.
