Showroom A few years later, I'm finally ready to finish this 2DOF project！

This design has been on the drawing for a long time.

Aluminum profile design

The bracket parts didn't arrive. Test the motor. Everything is normal.

Due to the limited space for seats, the bracket must be designed to be compact. At the same time, there is no welding condition, and in order to facilitate the adjustment, the final choice of aluminum profiles.

Order aluminum profiles today. This seat and seat belt have been here for a long time.

Motor no load test and software setting.Aluminum profile on the road, worry!

Thanks for noorbeast's attention and advice.
Using circuit and driver:
arduino nano
Monster Moto Shield VNH2SP30 stepper motor driver module
12V 80A power
12VDC 180W 3800RPM Motor ,Gear ratio=25:1
10K potentiometer

Circuit reference，thank you Racingmat

No problem now. How to test? Work long hours with load?

The ordered aluminum profile may be delivered in the evening!Little excitement!

Handbrake made a few years ago.

A little bit of progress.
3030 aluminum profile. After many years, I finally began to assembly work happily.
The key parts are reinforced.
The assembly work will continue tomorrow.

Processing aluminum.

Continue assembly. The height is not enough，need to buy accessories to improve the height.

Buy some of these long ones，have to wait again!

The accessories haven't arrived yet. I can't help but put them together to see the overall effect.
When it's completely installed, power on and test the machine. Keep waiting!

Power on test. The motor shakes a little. There's nothing else wrong. There's no time for the game test.

A simple temperature monitoring and alarm device is made for fear of overheating and burning of the monster motor driver module. It specially monitors the temperature of mm and motor, and alarms when it exceeds the set value.
