2 dof add lost traction

Hello, I have my simulator with 2DOF with the motors and Arduino with SMC. I want to add traction loss. Do you have any idea how I could add the motor to add traction loss?
i have thin motor
My simulator is a little dirty because of the repairs I'm doing.

any suggestion is appreciated

The referenced thread mentions using Extra1. My understanding is that for SimTools 3 you simply use Yaw. Works for me.

Not sure what the tile is it looks like luxury vinyl or ceramic. If the wheels are riding on vinyl then it’s likely they will cause damage. If they are on porcelain then they might crack or chip it. If you plan on using wheels that go any direction then consider what happens when you change direction. I have unidirectional wheels that go the way the rig goes.

You will need to anchor the pivot point to the floor. I don’t know how much you care about the floor but both of those issues could be solved by a base plate of some sort. I use a 4x6 sheet of plywood. There are steel bars 3mm x 30mm x 250mm that the wheels ride on. I don’t know what a thin motor is or what that means so it needs some clarification.

You either have to attach the motor to the back of the rig and push against a stationary point or mount a stationary motor on the baseplate to push against the rig, My motor is on the rig mostly for access.

Oh, okay, thanks. Yes, I'm going to order the material and we'll see. I'll show you photos. Norbeast, thanks. I couldn't find that post and look at what I was looking at... I thought about an iron and having the simulator move. I'll change the wheels, the ones that rotate 180º, I'll leave them fixed so it moves from left to right.
Although I don't mind leaving the motor under the seat.
The Arduino is with SMC. Do you know if I have to reprogram the Arduino for the third axis?
Thanks

If you are using a lever arm with a gear motor SMC will work as is.
