Hi all,

First time poster so i hope you'll excuse if this is a simple fix. I'm attempting to make something like an ArcDroid for a uni project but I've run into a road block. I'm using a MESA 7i96s as my controller and two knock off tb6600 as my drivers. after using the Pncconfig i got both my motors spinning in the XYZ setup, but once i tried to change it to SCARAkin, it didn't work. At first it loaded but was still in the XYZ config, then once i changed enough it stopped working outright. At the moment I'm aiming for simple motion control and I'm not sure if the issue lies in something I'm doing or in my coding. I've made several attempts so i have multiple files, mostly just coping from the existing SCARA config that exists in LinuxCnC but also from consulting with ChatGPT. Any help would be greatly appreciated, functional files for something like this would be a life saver and a more direct line to someone who is happy to provide help would be out of this world.

Why does everyone go to ChatGPT for help?

ChatGPT is kinda stupid and makes errors sometimes.

Though it can be helpful, I admit.

Why do you have an XYZ config if you only have 2 motor drivers?

Create a new config with PNCConf and then try twaeking it with PNCConf, editing the files manually is great,but it's easy to accidentally break the whole thing.

With PNCConf, you can safely edit stuff withing the guided prompts of the GUI.

I recommend you use AXIS as your GUI, and Ipresume you already are.
