I've finally finished my build of the AR4-MK2, and my first test was to put it to good use delivering chocolate to me... Check it out here: https://youtube.com/shorts/qM_0qH6fCgY Cheers, Jacob

Hi all, I've managed to get v4.3.1 of the control software running on Linux (Ubuntu 22.04). I've uploaded my tweaks to GitHub and updated the readme with the additional instructions for linux, for anyone else that might want to run it on linux. The repo is: https://github.com/se1exin/AR4-Control-Software-Linux @chrisannin I've included attribution to you and links to the original source in the readme, if there's anything else license-wise you would like to me do in regards to the public repo, please let me know and I will make those changes. My changes should also work on Windows as I've included platform checks in the code rather than simply removing Windows-only code, should you want to include those changes in your next official software release. Cheers, Jacob

Hi there, I've started 3D printing the parts for the AR4-MK2 and have been preparing to purchase the electronics, however I noticed that stepperonline does not sell the motors in the AR4 Upgraded Kit as individual products. I was hoping to purchase the motors in batches over time so as to avoid import tax (the main bundle is AUD $1085 which will incur an import tax of $180), as well as to make it financially easier for me to purchase the parts. I'm sure other hobbyist looking to build the arm have considered the same approach to aquiring the parts. I can only find one motor listed for individual sale (23HS22-2804D-YGS50-AR4), unfortunately none of the other motors from the bundle can be found on stepperonline.com (http://stepperonline.com)when I search for them. Are there any alternate/compatible motors that can be purchased individually that will do the job for each joint? Cheers, Jacob
