AR3 in Florida
Hi everyone, I am starting an AR3 build in Aluminum. I purchased from Chris the hardware kit and the 3D models. I was able to import them in F360 and have spent the last week CAMing. I am planning to machine most parts on my PCNC1100 - wish me luck Here are all the stock parts /images/forum/media/5e2b8c4062b9befb.avif I just received today the hardware kit, the motors and drivers kit. I just started sorting thru all the parts. This is a very exciting project with a lot of learning in sight. Many thanks to Chris for sharing his work and detailed instructions.

AR4 Round 2 : A summer project
Hi all, I build an AR3 before and converted it to an AR4 later. See my original post here: This summer, my nephew and a friend are looking for an introduction to machining and robotics. So with the help of Lael (16) and Benjamin (15), we are going to build an AR4 by machining all the pieces. The goal is to complete the machining and the build in 2 weeks - an ambitious goal ! To get the project started on a good track, I have prepared the material inventory and most of the CAM work: https://anninrobotics.vercel.app/media/oldsite-53bb79a4-6507-5e7b-850c-40572c2df516?f=.webp My goal is to machine the parts for J1 before their arrival in July in order to give them a head start.
