MY own 2 dof diy

yes this what i thought but i wasn't sure enough to do it, so you think it will help me achive easy movment with low backlash?, and where should i place the damper if i placed the motor forward?.. Thanks

i changed motor position and now i got too much movment and its not stable at all, i dont know what to dow, i add tringle in front that i thought it will help but nothing changed, help

yes that best solution ، thanks

i moved motors to front side under pedals but still green line not close to blue line, i use 300w 12v motors, 100a controller , smc3

like this

this with 750 kp , 170 pwmax

Hi, my 100a motor controller burned ☹️, so what you suggest to use instade of it? cheap but good drive controller?.


ibt-2 cant handle my 300w 12v motor, 100a controller is good but i want something butter because its taking issue when moving like its hard to move with it i mean its not give good power

will dual MonsterMoto shield as one will be batter than 100a driver? i tried dual ibt-1 as one before but it shutdown in action

i used this one that burned


so if i use 2x 100a as dual motor driver will work with this one and give more power?

because each one cane move 2 motor so i use 2x100a to control 2 motor?

Hi @noorbeast ,

i'm thinking to repurchase the same motor drive i used before 100a 12v, but i think my motor got too much load because of that it burned.

so i want to change middle shat position to forward because when i attach it i didnt try center of gravity.

i got new arduino and new 100a motor driver,

in smc3 its working perfectly, but in simtools the left motor react slowly, when i move it slow its moving at same time with right one but at speed its slow to react.

i change usb cables, tried with another arduino, system languge and region set to united states, reinstall simtools and driver, change power supply .


but nothing helped.






when i disconnect the right motor its working perfect, so i think my psu cant handle two motor at same time? but i used it before and its was perfect! or the motor driver cant move 2 in same time but its new and i used it before!

Where are your grounds from your motors going? Or are these motors not susceptible to polarity/current change when DIR is changed possibly sending current spikes back to your 100a controller via the platform frame. The motors are mounted on the metal frame.

i found out the problem, the psu is the problem , i tried with extra another one and its moving at same time but slowly because of low power.

Thanks for help, but i what watt Psu should i take for my motors, 12v 300w motors i have.
