Operating Manual for 3D Printer BT1.2 5. Printing 5.1 Starting printing - programme (*.gcode) The device is only able to run (read) programmes (files) in the "gcode" format, generated by special software (called "slicer"). This software is able to generate a programme for controlling the device from the part model that we want to print. - Page 25 Operating Manual for 3D Printer BT1.2 Start and stop the programme on the TFT32 control panel 3. select the desired .gcode file 1. basic (default) screen after 2. press the "PRINT" icon startup. 3.

Page 26: Pad Calibration
Operating Manual for 3D Printer BT1.2 5.2 Print pad calibration After the device has been completely assembled, the print pad must be calibrated. This step is very important and fundamentally affects the first layer's adhesion to the surface, therefore the print quality and the overall result. For this reason, we recommend that you are very careful when performing this operation. - Page 27 Operating Manual for 3D Printer BT1.2 Electronic printing pad calibration - unevenness mapping - "MESH BED LEVELLING" The printer software allows you to adjust the nozzle height during printing according to the pad's unevenness. However, this unevenness must be measured in advance and stored in the printer's memory. Follow the steps below.
- Page 28 Operating Manual for 3D Printer BT1.2 Introduction of a new printing string (filament) Extruder: this is the part of the equipment where the plastic is melted. The filament is pushed in by the motor, the drive and the pressure feed gear. This system is called a "Direct-Dual drive". The extruder is designed for filaments with a diameter of 1.75 mm.

Page 29: Restarting The Printer - Reset
Operating Manual for 3D Printer BT1.2 5.4 Restarting the printer – RESET You will need to restart the printer either due to an emergency stop, or if the printer stops for another reason and requires a restart. Usually thermal protection, e.g., when you press a cold steel plate on a pad that has just been heated and sudden temperature fluctuations occur. -
Page 30: Maintenance
Operating Manual for 3D Printer BT1.2 Maintenance 6.1 Moving parts Only carry out maintenance on moving parts when the device is switched off and disconnected from the mains. Due to the fact that the moving parts are stressed by extremely small forces, the device does not require special regular maintenance. - Page 31 Operating Manual for 3D Printer BT1.2 Heating the pad The "EXTRUDE1" button switches to "BED" and vice versa when pressed. Set the temperature with the "+" and "-" buttons This menu is for both heating the pad and heating the nozzle.

Page 32: Printhead (Extruder)
Operating Manual for 3D Printer BT1.2 6.3 Printhead (extruder) Before every print, we recommend wiping the heated nozzle (to approx. 220°C) with a cotton cloth to remove the rest of the molten filament. Use leather work gloves for this operation. Take extra care - risk of burns! Otherwise, the print head does not usually require specific maintenance. - Page 33 Operating Manual for 3D Printer BT1.2 Nozzle replacement procedure Take extra care during this procedure. This is handling a hot part. Therefore, only handle hot parts with the appropriate tools! Protective work aids - leather gloves - are recommended. 1. Remove FAN2 ventilator, nozzle blower and silicone cover (assembly see p.6)
