2DOF seat mover + ardunio r3+IBT2
Hi all
First of all,thanks everyone here.
Materials of my simple project:
1.channel steel 50x50 which is suitable for fixing motor ,some 50x50 angle steel and steel corners

2.150w dc motor---25:1
CTC 40mm

3.universal joint from tesla half shaft
4.ONE 500W LED power supply

5.10k potentiometer x2,
IBT2 x2
ardunio r3

6.I use smc3,and follow the thread below,but i made a mistake that i set the clip to255 and max limits to 255(max limits =0 is right) because i misunderstand the step6,so i don't get any movement at fisrt.

Initial Setup

I strongly recommend you follow the steps below if this is the first time you are using SMC3 with your simulator to reduce the risk of damaging anything.

1. Disconnect the motor power supply
2. Make sure Simtools is not running – we’re not ready for that yet!
3. Wire up the Arduino (with SMC3 installed) to your H-Bridges and connect to your computer via USB
4. Run the Windows SMC3 Utility software and make sure it communicates with the Arduino (There is no need to set baud rates, they are not configurable)
5. Set the Kp, Ki, Kd, PWMmin, PWMmax, PWMrev to 0 for ALL motors (This will make sure the motors don’t move)
6. Set Clip to 255 (you need to do this first) and Limit to 255 (This will give you plenty of margin if something goes wrong while setting up)
7. Turn on the power to your motors – nothing should move at this stage!
8. Set Kp to about 400
9. Now slowly, increase PWMmax… at some point the motor should start to move. When it does check the “Green” feedback line is moving toward the “Blue” target position.
   • If it is then that motor and feedback is wired correctly - proceed to test other motors.
   • If it is moving away turn off motor power immediately (or quickly reduce PWMmax again). In this case you need to either reverse the wires to the motor being tested –OR– reverse the +5V and GND wires to your feedback pot for the motor being tested (do not do both). Restart the test from the beginning.
10. Do the above for each motor

finished product

Great work would love to see a video of it in action

I will upload a video later.and one more question:
How to change the degree of motor? in smc3 code or some where to set ?

Do you mean for a starting point of the seat or to increase the amount of movement you have ?

decrease the amount of movement i have,it's too much now,that is not real i think.
thank you very much

Hi can you post pictures of your setting in simtools, axis assignments and tuning centre please ?

is that ok?
I just want to decrese the amount of movement while don't decrease the power of motor

Hi if you want to keep the speed then dont touch the tuning centre if you want to reduce the amount of movement the lower the % of which ever dof is moving to much but to be fair yours look low anyway.

Upgrade:
The backlash is annoying,so i add two damping(use in motocycle) .Now the response is much more tight and comfortable.
And now it also can support me with power off
