If the probe is connected to the Z-Min pin, enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. For Marlin and earlier, if the probe is connected to any other pin, enable Z_MIN_PROBE_ENDSTOP. The probe-specific pin is defined with Z_MIN_PROBE_PIN. Most boards have a default, but it can be overriden in the configuration.

With this option enabled, by default Marlin will use the Z_MIN_PROBE_PIN specified in your board’s pins file (usually the X or Z MAX endstop pin since these are the most likely to be unused). If you need to use a different pin, define your custom pin number for Z_MIN_PROBE_PIN in Configuration.h. Probe Type. Marlin supports any kind of probe that can be made to work like a switch. Specific ...

It is not a major problem, you can change within the Marlin firmware and indicate that for Z- we are going to use the Z+, but you have to make unnecessary modifications. Where can I buy a BLTouch / 3DTouch? You can buy this type of sensor in any online store, since they are very common in the world of 3D printing. Below I leave you two affiliate links to Amazon and Banggood. Of course you can ...

How to set Z-probe boundary limits in firmware when using automatic bed leveling? Ask Question Asked 1 year, 9 months ago. Active 5 months ago. Viewed 20k times 10. 6 $\begingroup$ In setting up a probe for automatic bed leveling, the limits of the probing area must be entered in the firmware of a 3D printer. When using a sensor, how do you define the bed limits for the sensor in Marlin ...

In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Instructions are in the comments. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. It’s safer to leave Z as 0 here are calibrate this yourself later. To keep the probe away from the edge of ...

Marlin now includes a PROBE_MANUALLY option as a kind of faux probe. With this option enabled you send G29 repeatedly, once for each point, until all points have been measured. In-between points you must manually adjust the Z axis with G1 or your host software, feeling under the nozzle with a piece of paper or feeler gauge.

Set the XYZ distance from the nozzle to the probe trigger-point. The easiest way to get the Z offset value is to: Home the Z axis. Raise Z and deploy the probe. Move Z down slowly until the probe triggers. Take the current Z value and negate it. (5.2 => -5.2) Set with M851 Z-5.2 and #define Z_PROBE_OFFSET_FROM_EXTRUDER -5.2.
