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
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.
I was able to complete the wiring, the programing and the first tests, there are good and bad news:
J1 skips, I have about +/- 10 degrees of joint movement before the motor skips. I need the check the set screws and the pulley tension
J2 motion is good
J3 only goes in one direction (-) or down - can't manage to have it go up. I also have a lot of slop in J3 when I move the joint manually - I'm going to try to tighten the chain a bit.
J5 works fine but I think my alignment is off
J6 works good
I have tried to home the joints that move correctly individually but I get an error every time saying the joint is out of calibration. I guess the encoder response doesn't match the motor target position.
I have tried the limit switches manually but they do not seem to response. Is there a way to troubleshoot the inputs (Limit switch and encoder data ?)
Any help or suggestion welcomed
