octopi

[codyb4175]

I am trying to get octopi setup for my printer.
I am running into an issue setting the printer origin in octopi, the only options are center and front left, our Eclips3d being in the back left seems to be something I am having trouble overcoming.
In the process of making adjustments trying to figure out a solution for the printer origin I have started having issues with losing connection to the Azteeg.
I have not been able to find much if any information using the Azteeg x5 with octopi.
Any thoughts, suggestions or links are greatly appreciated.
Thanks,
Cody

No, origin (0,0) is in the front left. Homing Y is at MAX, in the back. I use Octopi with no problems at all. One thing you might want to check on the communication problems is to just set the baud rate for whatever you configured in the config.txt (usually 250000) auto can be unreliable. Also make sure that you have a good quality powersupply and USB cord for the Pi. Either a real Pi powersupply (they put out 5.25v) or a quality USB adapter that can supply at least 2.1a. When I get a chance I will post pictures of what I have setup in my pi. But, from what I remember there is nothing unusual to do.

Thanks, I'll compare your settings to mine, try another power supply (currently using the canakit thats 5v @2.5A), and play with the baud rates some more.

I've tried running my pi3 on a USB battery and it seems to be connecting and maintaining connection, I am going to try to get the official pi supply that runs at the previously recommended 5.2v as my USB battery is supplying 5.17v on average.
It seems my origin issue is a result of me not noticing I have to bad drivers on my x5, the "X" and "E" are not working, I have sent an email to Panucatt to see if they will repair/replace.

There was a config.txt change on Smoothie that will make the E not work. Make sure that you have the latest config. I have a collection of configs posted in the general section of this board.

Rick, you saved the day once again. Your config file has all my axis working, must have changed something on the x and not realized it.
My biggest problem now is that the z doesn't want to home. I can manually move it fine, but when I try to home the z it moves to the bottom of the machine instead of the top, I tried setting the "gamma_homing_direction" to "home_to_max" just to see what it would do and it does not move.
Any thoughts on the Z?

You want to home to min, not max. Also make sure the home to min value is 0 in the config.

Odds are your z axis motor is flipped. Keep in mind that when the bed moves up, it is actually reducing the z height and thus moving z down. So when you hit Z+10, the bed should move down, and Z-10 should move up. Hope this helps!

Thanks 3D, the z axis needed to be inverted. Honestly thought I had tried that, but we all know thinking don't do anything be get ya in trouble.
All issues from the original post are now solved.
Nothing to do with OctoPi.
Jacked up firmware
Insufficient power supply
Thanks for the help

Does anyone know how to setup a static IP for WiFi on Octopi? I have Octopi working great with the Raspberry Pi 3 and Azteeg x5 v3 but sometimes its hard to find on my Lan since it changes its address every time i start it up.

I setup the Octopi Image for my raspberry pi and i went into the network.txt file to set up my WiFi and it works but its not static.

I can look into this for you if needed, but I would set up a static IP address in the DHCP server of your network router.
