MY own 2 dof diy

could anyone help me please?, i stuck on wiring and i cant continue until i know how to wire exactly, like pin (A1) to arduino number (number)

this board but i'm stupid i don't know how to wire it

100a dual channel h-bridge

Hi, my potentiometer changed center when there is high movement because the attachment to the motor not that good, so any suggestion to attach it to the motor note that the lever size is 20mm so its hard to make a holder because the pot is too small to it, so any other suggestion to replace it with hall effect?

The tubing with jubilee clips isn't the most stable of solutions. You might want to look at flexible couplings used to connect motors to lead screws for cnc. They come in a range of sizes and you might find something that fits. Personally, I run my pots (encoders in my case) through gears. If I need to recenter all I do is pull off the gear on the pot, rotate it a little and put it back on. This gives reasonably fine adjustment.

already saw, but they perfect thins i saw its this thing


but my motor lever size 20mm and i couldnt find the same size

Hi, any idea for how to connect pot to the motor ? , my motors shaft is 20mm help with idea

Arguably this is the hardest part of any build (IMO). Because most builds tend to be different from each other, folks use different motors, want their machines to move different amounts & the pots people use have different amounts of rotation etc, mounting the pots becomes a creative challenge. On my build I used cogs which I 3d printed, allowing me to mount the pots next to the motor shaft & kcontrol the amount of rotation I wanted. Others mount them inline with the shaft, creating a little stand off mount and having the rotation match the motor rotation.

I guess what I'm saying is there is no right way of doing it but also, it's one thing that most people can't directly help you with. You need to look at your specific build, think of all the possible ways it could be done & all their inherent weaknesses & try & pick the most sensible solution that your able to make.

Here's what I did......

Oh thanks bro, but already saw that and no idea helped me, as i say the motor lenth is 20mm

Thanks so much bro

hi, i used 2xibt-2 for each motor, right motor work great in smc3, but the left one keep moving and not acting to the pot, i replace the pot and used another arduino and ibt-2 but not fixed, what to do? i tried to connect the right motor wiring to left one to check if the problem from the motor but its work great but the issue not solved because its same in right motor

still using the left pot
only changing wire without moving pot, but change A0 with A1 cable on arduino also

i will try, thanks
