When I run G28 the X & Y home on their respective endstops as before, and Z now moves to the middle of the bed and homes Z using the Z probe. Units will be in steps/mm unless inch mode is set with G20 (which requires INCH_MODE_SUPPORT). Raise Z and deploy the probe. 1 Reply Last reply . À noter que la position de repère peut être différente du centre du plan cartésien. This is the moving speed of the axis when homing in [mm/min]. thermal PIDTEMPBED M304 - Set Bed PID . First created in 2011 for RepRap and Ultimaker by Erik van der Zalm et. Try using Z offset to adjust where your 3D printer starts printing. The original machine had a Melzi and I replaced with Ramps 1.4, replaced Z bearing and added REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER, everything works great with marlin 1.1. More .

With this option enabled, by default Marlin will use the Z_MIN_PROBE_PIN specified in your board’s pins file (usually the ... (mm) to raise the probe (or lower the bed). Then you should either switch to a Y max endstop or move the min endstop so the probe can reach the front edge of the bed (as you have). Am I missing something? Note that in Marlin 2.x, these constants are replace by an array definition: #define NOZZLE_TO_PROBE_OFFSET { XXX, YYY, ZZZ } Where ZZZ is the Z offset. However it is also told that the z end stop is at the minimum and it searches upwards for it. Example M666 X2.1 Y3.3 Z2 or M666 X-2.1 Y-3.3 Z-2 And there isn't anything I can do for Center Z0.7? That is where I will start adjusting the DELTA_RADIUS. Loading More Posts. (5.2 => -5.2) Set with M851 Z-5.2 and #define Z_PROBE_OFFSET_FROM_EXTRUDER -5.2. It is the total number of axis (3) plus the number of extruders (1). This happened to me using the Marlin 1.0 beta. Now adjust Z height to fit a piece of paper and note the negative Z height (either through the LCD or through an application over USB) M851 Z-1.23; // Define the Z offset M500; // Store the settings M211 S1; // Enable the end stops again Please note that -1.23 is a … For X and Y you have to … If your Z position reads zero, you’re done.

Noter la valeur affichée de la position du Z sur l'écran du boitier (additionner la valeur absolue affichée à l'épaisseur de la cale utilisée) 11. … If your Z_MIN_WHILE_PROBING were implemented, if the printer were powered off (or Marlin crashed, etc) with the head at any Z distance greater than Z_MIN_WHILE_PROBING there would be no mechanism to begin a print on the next poweron, since Marlin will never move in the negative Z axis except during G28 probing and after probing completes successfully. 4 Posts. G0 Z-0.2 G92 Z0. Use M92 to set the steps-per-unit for one or more axes. The numbers indicate I have a CONCAVE plane. This setting affects how many steps will be done for each unit of movement. I wonder if this is the standard behaviour of the firmwares, as I think it should be safer not to allow negative coordinates in the first place. Z-offset on Marlin firmware. Il faut que le signal d’interruption soit très précis et très rapid Reply Quote. Bonjour @netcubik, oui j'ai résolu le problème, voici la solution : Dans mon fichier Configuration.h, j'ai passé la valeur de la ligne 767 (767 dans mon cas, sur ma version de Marlin) #define Z_PROBE_OFFSET_FROM_EXTRUDER 2 // Z offset: -below +above [the nozzle] de 2 à 0. 3.

(Z) G1 X0 Y100 Z2.0 (CENTER) G1 X0 Y-0 Z0.7 So, in M666 would those be negative or positive offsets? Also, it's good to enable Z safe homing, so it homes at the center of the bed (Marlin is clever enough to know that means the probe is at the center, not the actual nozzle) First, start with -2.0mm offset, then you'll be able to edit the offset right in the printer's menus, mine's currently at -1.850mm or so.

The Z sensor is on left (positive Z) of the hot end, that is required because there is not enough room to put it on right or rear and still cover entire surface with hot end and sensor. The easiest way to get the Z offset value is to: Home the Z axis. When I run G29 (3 x 3 grid) all 9 points are probed and the LCD tells me that I am at z=0.79. Another negative point since if you use glass you will be very fair and in any failure your nozzle will go through the glass with the consequent risk of breakage.
