Re: Updated Marlin customized for Mendel90 - 10 years ago
If I remember correctly, I was looking at the schematic reading the existing code and g-code and test my predictions by simply changing an existing end stop pin, and then checking the endstops status ( M119 ). I'll think the EXT-A2 is A.pin 29 EXT-A3 is 28, and EXT-A4 is 27 Because the M42 P29 S255 is the gcode command that activates my bed fan (pin under Z_MIN_PIN) Changing X0 Y0 probably isby miharix - Mendel90
My mod on Updated Marlin customized for Mendel90 - 10 years ago
If I didn't forget something, those are my steps: 0. Bed is from 214mm x 202mm x 3mm aluminum (from www.plocevine.si) - same dimensions and mounting as original glass from nophead 1. Sensor is "LJ12A3-4-Z/BX Inductive Proximity Sensor Switch NPN DC6-36V" from ebay seller "gameszone.no1" 2. The small PCB on the head is little customized. 2.1 Drilled a 3. hole and inserted single pin from pinby miharix - Mendel90

Damn, I forgot to post. I got my Z-probe working & also kept homing up not down on my nophead mendel 90. I'll post the minimal changed source and HW details tomorrow about the same time. (It's on a laptop, currently in office)by miharix - Mendel90
Re: Updated Marlin customized for Mendel90 - 10 years ago
Still no luck. I did this: Under line 1208: #ifdef MELZI commented out line 1210: //#define FAN_PIN 4 added line: #define Z_MIN_PIN 4 I do use fan, but I did this just to make for simpler first testing. uncommented line 399: #define ENABLE_AUTO_BED_LEVELING But when I run compile I get: #error "You must have a Z_MIN endstop in order to enable Auto bed Leveling feature!!! Z_MIN_PIN must poby miharix - Mendel90
Re: Updated Marlin customized for Mendel90 - 10 years ago
But where in the code, do I define the probe port?by miharix - Mendel90
Re: Updated Marlin customized for Mendel90 - 10 years ago
Hi, I'm trying to add z-probe on my Mendel90. The probe is a "Capacitive Proximity Switch" and on the bed I replaced the glass whit 4mm aluminum, so the probe can detect it. It's mounted using this holder: So far so good. If I understand correctly, it should work using this firmware like normal switch but without the servo, but.... I cant find the information on which pin of those 10 availablby miharix - Mendel90
