Solkane Hi,first thanks to this great printer firmware, with the Online Conifgurator it's easy for beginner as me.First a few facts which hardware and whats my problem:Melzi 2.0 Board + 5 Button LCDRepetier 0.92.9 (working good without Z-Probing&Servo)BLTouch Probe I want Z-probing with the BLTouch probe:1. Wired is the BLTouch as in this post: https://plus.google.com/113792662927481823969/posts/DBkfSkQArGG (BLTouch Endstop wire is on Z-Endstop on the Melzi + Servo Signal on the PIN A4)2.Configuration.h is setup with the configuration tool as in this thread: https://forum.repetier.com/discussion/2477/bltouch-configuration-on-makergear-m2-with-rambo<br/>3. The problem is the PIN A4 (the producer of the BLTouch said: Please add below at "pins_SANGUINOLOLU_11.h"#define SERVO0_PIN A4 ) I know this is for marlin. But how should i define the PINs ? In the configuration tool i can't select Analog Input PINs.Only Digital PINs and when i select Digital PIN 4, my fan doesn't work after this change.Here is the schematic from the Melzi board:http://images.google.de/imgres?imgurl=http://reprap.org/mediawiki/images/thumb/7/7d/Melzi-circuit.png/1000px-Melzi-circuit.png&imgrefurl=http://reprap.org/wiki/Melzi&h=584&w=1000&tbnid=CgJhB7tB_1MuFM:&vet=1&tbnh=90&tbnw=154&docid=yvtyFcNEsY_LJM&usg=__Okaa0NT5-3dpBojazLHvK5bgTSE=&sa=X&ved=0ahUKEwinldHkrLDRAhVX-2MKHeg3BCIQ9QEIIjAC<br/><br/><img src="http://www.bilder-upload.eu/show.php?file=1ed020-1483813708.jpg" />Can someone help me ?
Repetier <font face="Arial, Verdana">A4 should be digital pin 28 according to this image:</font><font face="Arial, Verdana">http://images.google.de/imgres?imgurl=https://cdn.instructables.com/FZC/72A7/HI3TQE7F/FZC72A7HI3TQE7F.MEDIUM.jpg&imgrefurl=http://www.instructables.com/file/FZC72A7HI3TQE7F/&h=435&w=620&tbnid=hRk2whZXB_OjfM:&vet=1&tbnh=90&tbnw=128&docid=5wTswNHBB2LcZM&usg=__U4Gd3lvRjQisfLGjj5I-E1i08Dg=&sa=X&ved=0ahUKEwip9Kn7lrfRAhXbMVAKHSZ-DvgQ9QEIHTAA</span></font><br/></div>
nkuck Did you get your issue resolved? If so, please let me know your solution as I have the same problem. Thanks.
vinibali Hi there!Sorry for bumping this, but I had somewhat the same problem.The only pin which was left unconnected from the Zonestart LCD2004 display is the A4, for which the mapping is the pin 27:https://github.com/Lauszus/Sanguino/blob/master/variants/sanguino/pins_arduino.h#L82<br/><br/>
