| Electrically everything worked wonderfully. Unfortunately I noticed a problem after assembling the A5. The measurement of the available space above the momentary switch upper edge was wrong. The Y-gantry does not have enough room to move because the housing of the momentary switch was too high.\\ | Electrically everything worked wonderfully.

| + | __**Application proposals**__\\ | ||
| + | Every modern slicer program, such as Simplyfy 3D, Cura, Slic3R, etc., has the ability to define a START and END GCODE block. Among other options you can also enter commands for the control of the power supply. \\ | ||

| + | M109 S190 ;Set Hotend Temperature + Wait | ||
| + | G92 E0 ;Reset Extruder | ||
| + | M109 S180 B250 F1 ;Autotemp on 180...250C | ||
| + | ;STARTING GCODE END ---------------------------------------------------------------- | ||
| + | </ | ||
| + | Power OFF Machine if no movement for 45 minutes: Normally, this case will not occur because the axes are constantly in motion during printing. If the user stops the printer but forgets to turn it off, the A5 will turn itself off after 45 minutes to save energy.\\ | ||
| + | \\ | ||
| + | < | ||
| + | ;ENDING GCODE START ----------------------------------------------------------------- | ||
| + | G92 E0 ;Reset Extruder | ||
| + | G1 X0 Y300 Z320 E-3 F4000 ; | ||
| + | M104 S0 ;Turn hotend off | ||
| + | M140 S0 ;Turn heatbed off | ||
| + | M109 R45 ; | ||
| + | M84 ;Disable steppers | ||
| + | M81 ;Power off | ||
| + | ;ENDING GCODE END ------------------------------------------------------------------- | ||
| + | </ | ||
| + | At the end of the printing process, the 3D printer waits until the hot end has cooled to 45°C and then shuts itself off.\\ | ||
