I'm no longer maintaining this repository because I've completely rebuild My ender 5 with BigTreeTech's SKR 1.3 with TMC2208 drivers.

G92 is the most misunderstood and maligned part of EMC programming. T0 G1 X100 Y200 F3000 G1 X100 Y235 F3000 ;extrude 10mm T0 G92 E0 G1 E10 F200 G92 E0 M117 10mm Extruded. I'm entering G92 E0 before each print and haven't had a huge retraction at the start of the print. If the filament is left at home position for too long while the nozzle is hot, the filament can ooze out. G0 Z0 G92 Z0.1 First, we move the nozzle to Z=0.Next, through the G92 command, we tell the printer to, from now on, treat the current position as Z=0.1.This effectively applies an offset of -0.1 to the Z-axis, since if we now executed G0 Z0 again, the nozzle would move down 0.1mm. On to the next issue. You can trick the printer into applying an offset using the G92 command:. G92 E0; zero the extruder G1 E10; extrude another 10mm. On to the next issue.

G92 E0; G1 F200 E3; G92 E0; Si vous souhaitez régler vos PID de façon automatique c’est faisable via la commande du menu suivante : Une fois PID Autotune lancée, laissez l’imprimante faire le job, elle rentrera les valeurs toute seule une fois finie. Use your printer's LCD screen, or send it: G92 E0, then G1 E100 via your printer control software. Marlin's latest firmware now included pre-made configuration for Ender 5 so you should use that as a starting point instead of mine. I would still be curious as to what other settings you put in a start file. This change has confused many users. ;BigBox Calibration Code End When I print this from SD, did not try from a host, the bed begins to move when the "G92 E0" is executed and moves and moves.
