Use da hammer

This looks very interesting. Do you have any videos showing how it works?

use locktite on the setscrews too

Make sure that the linear rod is pushed in far enough so that the set screw actually bites onto it.

There are set screws to hold those 3mm rods. so drilling the hole out to fit them should be fine:

Wow! Very cool! Is the software totally separate to the AR4 control software?

Do you have any videos of this working Aleksandr? This looks really great. Cheers

I have not seen that for the AR4, but it would be cool to implement it.

What do you mean by leader arm?

you can buy mk3 files here: https://www.anninrobotics.com/product-page/ar3-complete-solidworks-assembly-step-files just find dimensions from there these parts changed: https://www.anninrobotics.com/product-page/j6-housing-and-gripper-mount-for-upgrading-to-mk3-from-previous-versions

Thanks for the reply, no worries :) Cheers, Johann

Sounds like a loose connector, make sure everything is properly connected, swap out the USB cable, and even plug directly into the arduino to the PC without using the keystone connector. See if that helps.

Hi Henry, Check the outer diameter of your pneumatic hose going to your gripper, the standard is 4mm OD which you can purchase the push connectors from here: https://a.co/d/5jWbbre Cheers, Johann

Bloody awesome! 🤣

It sounds like you wired the switches to NC (normally closed) and com. Rewiring them to NO (normally open) should fix that. Maybe.

Hey Paul, Very cool tool changer. Have you seen the 7th axis? perhaps you can start with the robot ~1m away with enough space to home it, then move it close to the mill for a tool change, and then move it back. That way it isnt so close to any chips.

Hi Elijah, So does that mean the end effector can hold 2*161% = 3.22 kg? Or will there be another bottleneck in the joints making lifting that weight impossible? Cheers

Hi Rocco, This is an old post, since then Chris Annin has integrated vision control into his software. If you look on his YouTube channel for programming the arm there are some times when the serial string shows up. Cheers, J

Does this increase the payload at all? How much can you lift with this upgrade?
