I built a Dual X Carriage with Dual Z Motors a few years ago and want to upgrade to the newest stable version of Marlin. This is what I am currently running, 1.1.0 RC3 Hardware is Oversized i3 with the following: Azteeg X3 Pro with Viki 2 Dual X Carriage Dual Z Steppers with Separate Endstops for leveling Here are the questions that I have: 1. What version should I upgrade to? 2. Where do I find/put the pin assignments for the Extra Z and Extra X Steppers as the newer firmware just mentions that it will be assigned to the next E stepper. I am not a programmer and it took me a few months to get it working the first time so I wanted to ask for help this time around. Here is a link to my current firmware that is working (except for the basic buggyness). https://drive.google.com/open?id=1pPKD4ijfQ9fkFAYNaPhvg9hWHwB2qdae Here is a video of the printer doing a duplication print if any clarification is needed: https://youtu.be/aOn0jR-iBpc Thanks for any help you can give. https://reprap.org/forum/read.php?415,799128,799128#msg-799128 Wed, 09 Sep 2026 00:04:42 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?415,799128,835179#msg-835179 https://reprap.org/forum/read.php?415,799128,835179#msg-835179 datesheet Firmware - Marlin Mon, 01 Oct 2018 13:31:39 -0400 https://reprap.org/forum/read.php?415,799128,799532#msg-799532 https://reprap.org/forum/read.php?415,799128,799532#msg-799532
Is there a better forum to post to with users that may have a better understand the Marlin firmware?]]> mic03167 Firmware - Marlin Tue, 05 Dec 2017 09:19:01 -0500 https://reprap.org/forum/read.php?415,799128,799128#msg-799128 https://reprap.org/forum/read.php?415,799128,799128#msg-799128
This is what I am currently running, 1.1.0 RC3

Hardware is Oversized i3 with the following:
Azteeg X3 Pro with Viki 2
Dual X Carriage
Dual Z Steppers with Separate Endstops for leveling

Here are the questions that I have:

1. What version should I upgrade to?
2. Where do I find/put the pin assignments for the Extra Z and Extra X Steppers as the newer firmware just mentions that it will be assigned to the next E stepper.

I am not a programmer and it took me a few months to get it working the first time so I wanted to ask for help this time around.

Here is a link to my current firmware that is working (except for the basic buggyness). https://drive.google.com/open?id=1pPKD4ijfQ9fkFAYNaPhvg9hWHwB2qdae

Here is a video of the printer doing a duplication print if any clarification is needed: https://youtu.be/aOn0jR-iBpc
