Using this LDO Rook MK1 DIY kit is easy. First, make sure you have all the parts and tools ready. Then, start assembling the printer following the step - by - step guide. When it comes to printing, choose the right 1.75mm filament for your project. Keep in mind that the bed temperature should not exceed 110°C. For the best results, set the layer height between 0.05mm and 0.3mm. As for maintenance, regularly check the motors and fasteners to ensure they are tight. Clean the build plate after each print to remove any residue. Also, make sure to use the right type of power cord for your country. If you need to source a Klipper Screen, choose a reliable one that suits your needs. Have fun printing!
