Glad to hear it. Make sure to print out the AR3 model So you get the latest model. (It’s clean and sleek) If you get stuck, reach out.

Shipping time for the motors/drivers for me in TN took aprox. 2 weeks and $100 shipping - not happy about that.

Thanks for clarifying Chris, I was wondering that myself.

I’m using a Prusa MK3S 3D printer ($750 kit) + ($25/spool of fillament) the build came out strong and very clean looking. So that’s my recommendation for a solid 3D printer choice)

If you haven't found a solution to your permission error, please take a look at the link below. I had the same com port permission error and was able to resolve it. https://www.anninrobotics.com/forum/questions/ar2-software-troubleshooting-com-port-permission-error

Oh, got it. Thank you sir.

(I was finally able to get the AR2 software to communicate with the Arduino using the default baud rate of 9600)

Good news @Chris Annin! As it turns out, I'm fully retarded. The robot is now 100% operational!!! Regarding the com port issue: As my wonderful, beautiful, smart and sexy girlfriend pointed out to me while helping me troubleshoot... The AR2 software was in fact communicating with the Arduino Mega the entire time after all... ...fuck What happened was that I had my Arduino plugged into a shield that made it lay face down so that I couldn't see the orange LED on the board (outta sight, outta mind type deal) When I used the AR2 software and clicked the "Set Com" button with the appropriate channel, I would watch the python CMD window waiting to see something, letting me know that the communication was successful or something. The first click wouldn't produce any feedback in the CMD window, so I would click the "Set Com" button again thinking that something wasn't communicating properly (this is where the orange LED on the Arduino normally would have flashed, alerting me that it was in fact communicating with my PC - however, being face down I never saw it) As it turns out, the com port permission error that I was getting previously was caused my the port already being in use from the first time that I clicked the "Set Com" button. I guess that was the software's way of saying "Hey dummy, I'm already in use". So that was fun. Anyways, after we figured that one out, we tested the AR2 software again. Still no movement however. We then disassembled every wire on the robot and rewired it from the ground up. As it turns out, I messed up the wiring for one wire. The -5V DC wire connected to the motor driver. I had it wired into my 5V DC power supply's negative terminal (which disables the motor drivers, explaining why I couldn't get the robot to move) So if anyone in the future has the same issue(s) as me, here's are your solution(s). Oh and the AR2 software is in fact working on Windows 10, x64. Chris, I am very sorry for wasting your time regarding this issue, sir. However, I want to say THANK YOU VERY MUCH for trying to help me troubleshoot along the way!

Changed out the Arduino Mega 2560 for another one; no change.

While troubleshooting more, I did happen to find a few duplicate instances of "COM Surrogate" running in the task manager. I ended all those processes, but still no change. (Doing more research on the "COM Surrogate" - This is actually a normal thing to find in your Windows task manager and wasn't the root cause of my com permission error)

@Chris Annin is the AR2 software designed to be ran on x32 or x64 bit framework?

You're welcome sir. Good luck!

Taking a few pics now of my J5 limit switch location to see if that'll help you position yours. (Make sure to leave a gap between the J5 limit switch roller and the housing)

I also had this problem with my build. What I did was have my girlfriend hold the J5 limit switch in place by hand (loosening the set screws) while I moved the carrier back and fourth with my hands. We kept adjusting the limit switch's position a little bit at a time as I would move the carrier. We eventually found a sweet spot where the carrier would travel to the end position and the limit switch's lever was pressed in.

Oh I see now. So it looks as if your J5 limit switch roller is getting stuck on the aluminum frame of the housing? Is that it? Would it be possible for you to insert the J5 limit switch again (making sure to loosen your set screws formerly holding it place) but this time, sliding the J5 limit switch down, more towards the black belt behind it? This should allow you a bit of wiggle room in order for the lever to move freely.

In the future, when you post pics, down by the blue "Answer" button there is a few icons. Simply click on the camera and your pics will upload to the forum so that people don't have to download all your pics individually.

Nope, don't cut that off buddy. Give me one min. while I redo your pics.

I had a similar sounding issue as well but managed to correct it. Can you post a pic or two of your J5 limit switch and the housing setup?
