Homing Issue X-Axis (LIFTOFF) Hello Guys, Hallo Leute, I don´t know how to get rid of the approximately 50mm moving away after homing the second time from the mechanical or optical endstop!? Ich weiss nicht warum meine X-Achse nach dem 2. Referenzfahren sich ca. 50mm vom mechanischen oder optischen Endschalter entfernt!? What is causing that behaviour? I can´t find any errors in my firmware. Was verursacht dieses Verhalten? Ich finde keinen Fehler in der Firmware. I need to get rid of this so it won´t affect any movements later on. Ich möchte das loswerden damit es keine Folgefehler verursachen kann. Is it the firmware setting? Ist es die Firmware? Is it the Ramps 1.4 or Arduino Mega 2560? Oder Ramps 1.4 bzw. Arduino Mega 2560? Or just something I don´t see right now? Oder etwas was ich noch nicht weiss?

Does this also happen when you manually click the homeX button? Or is it only happening when you start a print?]]> sdavi Reprappers Mon, 05 Jan 2015 18:41:14 -0500 https://reprap.org/forum/read.php?4,450896,451126#msg-451126 Re: Homing Issue X-Axis (LIFTOFF) https://reprap.org/forum/read.php?4,450896,451126#msg-451126

Yes i used the online configurator!

Here is the file...

It is the Configuration.h file that is needed not the .ino file.]]> dougal1957 Reprappers Mon, 05 Jan 2015 08:59:51 -0500 https://reprap.org/forum/read.php?4,450896,451089#msg-451089 Re: Homing Issue X-Axis (LIFTOFF) https://reprap.org/forum/read.php?4,450896,451089#msg-451089

Did you use the online firmware configuration or edit by hand? The setting is in the Configuration.h file, post this config file if you are having trouble so we can have a look.

If you used the online editor, then its in the Mechanics tab at the bottom under: "Endstop distance after homing"]]> sdavi Reprappers Mon, 05 Jan 2015 05:25:18 -0500 https://reprap.org/forum/read.php?4,450896,451026#msg-451026 Re: Homing Issue X-Axis (LIFTOFF) https://reprap.org/forum/read.php?4,450896,451026#msg-451026
like I wrote I already tried it with both switches Optical and Mechanical!

I added the video to it!

@sdavi: Do you know where to find the 50mm setting?]]> Daniel Pfau Reprappers Mon, 05 Jan 2015 04:45:19 -0500 https://reprap.org/forum/read.php?4,450896,451005#msg-451005 Re: Homing Issue X-Axis (LIFTOFF) https://reprap.org/forum/read.php?4,450896,451005#msg-451005
If its not 0 then it will move away from the endstop once triggered, it might currently be set to 50?]]> sdavi Reprappers Mon, 05 Jan 2015 03:38:47 -0500 https://reprap.org/forum/read.php?4,450896,450975#msg-450975 Re: Homing Issue X-Axis (LIFTOFF) https://reprap.org/forum/read.php?4,450896,450975#msg-450975
One thing I would try first is swap the end stops from the y axis to the X axis and trigger it manually to see if it is an issue with the endstop itself.

Best to eliminate the simple things first. Also are you using a mechanical end stop or optical? I dont have much experience with optical endstops.

I primarily just use mechanical in my designs. I would recommend using a mechanical one for testing to eliminate that as a possibility.]]> edu3d Reprappers Sun, 04 Jan 2015 21:43:02 -0500 https://reprap.org/forum/read.php?4,450896,450896#msg-450896 Homing Issue X-Axis (LIFTOFF) https://reprap.org/forum/read.php?4,450896,450896#msg-450896 Hallo Leute,
