Slic3r seems to apply this setting directly to the generated z-values in the g-code, so it does not use a short version at the beginning of the g-code. I changed start gcode in the slicer a lot of times, but the problem is marlin because old gcode were printed wrong after firmware update. Basically instead of declaring the Z offset in your "start gcode", the gcode will actually call on a variable from the EEPROM to use as your offset. GCODE Z-offset So Cura assumes that Z=0 has the head touching the glass and because your first layer is 0.3mm thick (that's the default bottom layer thickness even though the remaining layer heights are all 0.1mm). The true EEPROM. In Slic3r I have configured the z-offset to -0.1 on the General page of the Printer Settings, but currently I'm evaluating Cura and can't find such a setting. Thingiverse is a universe of things. If you don't have the configuration.h, but have EEPROM enabled (able to save with M500), you can manually jog your nozzle to where you want 0,0,0. and use M428 to set that coordinate as your new home offset. Try using Z offset to adjust where your 3D printer starts printing. Note that there is … Alternative Z-offset using G-code commands. I have an inductive bed leveling probe and each time I remove the plate the Z offset seems to be off on the next print. Having trouble getting your prints to stick? After I followed a Step by Step tutorial for setting it up and double checked with another one, I connected everything and was ready to Test. Store memory: Make sure when you change your Z offset value, you don’t forget to click the store memory button on your Ender 3’s LCD if it’s running Marlin firmware. This means even if you disconnect and power down your printer and hit the reset button a hundred times and then re-flashed the firmware the Z offset will still be stored! Do you have access to Marlin configuration.h? Maybe the value of -2.97 for the Z_PROBE_OFFSET_FROM_EXTRUDER is retained in the EEPROM memory when you upload new firmware.. You could try to send the G-code M502 to the machine to re-load the values from the firmware overwriting currently stored values.. I executed home in all axis, calibrated the bed,when the printer starts printing, the bed goes down more than necessary, and when the filament is being extruded the bed is still down (more or less 2 cm) Anet E12 - Skr 1.4 Marlin 220.127.116.11 Upgrade - Anet Lcd wont work I recently bought myself an BTT Skr 1.4 mainboard with TMC2209 for my Anet E12 printer because my old mainboard broke. Want to print on top of an existing object? I have an Ender 3 and use Slic3r. Z-offset persitently stored in memory? The sequence of events I would like is as follows: Download files and build them with your 3D printer, laser cutter, or CNC. if so it's #define MANUAL_Z_HOME_POS, you can edit that value to change your Z=0.. If you use a G-code terminal to communicate with your printer, you can do this … Instead of re-leveling my bed and setting the Z offset by hand, I thought of adding starting G-code to do that for me but I've hit a snag. This is a guide to using g-code command M206 to set the Z axis home offset in the Marlin Firmware, a guide to a method of adjusting the gap distance between the hot end nozzle and the build platform.
