Hi, I used meshmixer to combine both stl files and printed them in one go. You just have to pay some attention when aligning the parts.

Hi Luis, I had a similar issue with some of my AR3 encoders at first and for me it was some kind of EMC interference that triggered the values. I grounded all the shielding of the encoder cables and since then the values from the encoders are perfectly stable.

Hi Sandy, I just finished building my AR3 and would also be interested in your post processor. It woulkd be great if you could share it.
