MY own 2 dof diy

look at this , he use same as my motor driver 100a and he connect battery with psu and solved his tripping problem.

@absyfadhel1 that's fantastic mate! Looks like a good solution. I'll check it out.

@absyfadhel1 by the way, which code are you using for that motor controller?????

smc3 mode 1

@noorbeast using bridge rectifier with 12v 1200w psu maybe fix tripping or i'm wrong ?

@absyfadhel1 so Rufu Dufus SMC3 code mode 1? Interesting. Non H bridge controller similar to the sabretooth by the sounds of that. Direction commands and PWM hook up? You may be able to also use @BlazinH SPS sabretooth code with that controller as well.

unfortunately it wont work because the one i have is same as monstermoto but instead of 40a its 100a

i mover my motor far front to be able to balance the rig, and i succeded in that. but now its twisting and cant solve it.

i added dampers but its kill the motion angle like its let the rig to move about 10% of the motion.


help what should i do?

yes, but not only backlsh, the distance between mid shaft and the motors is far, so when i move the seat with my hand its like twisting right and lift as same as not connected to the motor , its like in air so there is too much play and twist, before the motors were in short distance mid shaft and there is no twisting only up and down because of backlash, but now its twisting like the rod is not attached to the body .

i will try to shorten the rod lenth from motor to body to the shortest possible and will se if there is any diffrent.

i searched about panhard rod and i didnt figured out how to yuse it and where to attach it.


is it like this?

i cant use u joint because i just finished from remaking my rig and weld the rod so ut fhard to remove and its newly painted, i didnt know this will happend ☹️, i will do research about how i need to add the panhard rod

hi again, @noorbeast i do too much research and asked many friends but i couldnt find any udea how to solve the problem , panhard rod maybe a good i dea but i dont know how to attach it, i mean my motor in front side (foot mount) and its far from the seat because of that its tilt the seat when i just move it with my hand, when i increase the power if the damper its jot move and stable as i want, but there is like 10% of total movment.



any suggestion?

just ordered rod end joint m10 i dont now if its big enough , will try what you said. thansk alot

just to be sure, is this what should i do?
