Formbot Vivedino Trex 2+ and Trex3

This branch is intended specifically for the IDEX Trex machines. Please pay special attention to the driver selection in te top of configuration.h as several configurations left the factory. Since this machine does not use UART, the distinction between 2208 and 2209 is irrelevant so simply leave 2208 selected.

About Our Branches

The firmware branches maintained here are made possible by the support of sponsors like Tiny Machines 3D as well as our customer base through our 3D printing Services. Maintaining and developing these branches takes a significant investment, made up of time and machines. To support continued development, please consider your next 3D Printer related purchase from Tiny Machines 3D and thank them for supporting open source development. Or, consider us for printing services outside of your machine’s capabilities. Print service requests can be sent to d.menzel@insanityautomation.com and we will respond typically within 1 working day. If you do not need anything printed or a 3D Printer but still want to contribute, you can support us through Patreon.

Setup

All configuration options intended to be adjusted by end users have been placed in the top section of Configuration.h and have been documented there. There is typically a break line to segregate the standard configuration below. Anything aside from the upper options is intended for advanced users only.

Known Issues

• Marlin 2.0 had exhibited layer shifting issues with IDEX and other high stepper count systems early on. While we are confident the majority of cases have been addressed at this point, we would like wider feedback in order to confirm.

Support

This firmware is provided to the public as-is with no warranty or guarantee. It's based on a large open source project and there is no entitlement to support. That said, Tiny Machines 3D customers may obtain support through their normal support queue. I will provide support to Patreons as I am able. If you require more immediate support and are not a Tiny Machines customer, you may contact them at support@tinymachines3d.com about purchasing support hours. Aside from this, we are active many Facebook groups as well as several discord channels and typically help anyone we can when we come across them.

Future Goals

For this branch, we still have some active goals open that we plan to continue working on provided there is continued interest in the project.

• Slice Engineering Mosquito toggles
• M425 / G425 automatic offset and backlash calibration

If there is any interest in re-implementing the Chinese language screens, that's definitely possible at this point. In order to put the effort in however I would need to see a notable amount of interest in this.

Marlin

This is just one of many forks of Marlin. We don't try to bury that behind fancy marmarketingketting or anything else. As you can see from the links above, most of the work done here is submitted back to the mainstream Marlin branches. The end goal of every project is to get it to the point where it is merged and maintained there. See marlin resources, including how to contribute to the Marlin Project as well, down below.

Building Marlin 2.0

To build Marlin 2.0 you'll need Arduino IDE 1.8.8 or newer or PlatformIO. We've posted detailed instructions on Building Marlin with Arduino and Building Marlin with PlatformIO for ReArm (which applies well to other 32-bit boards).

The current Marlin dev team consists of:

• Scott Lahteine [@thinkyhead] - USA  
• Roxanne Neufeld [@Roxy-3D] - USA
• Bob Kuhn [@Bob-the-Kuhn] - USA
• Chris Pepper [@p3p] - UK
• João Brazio [@jbrazio] - Portugal
• Erik van der Zalm [@ErikZalm] - Netherlands  

License

Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.

While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
