Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Hi folks,
Figured it out. I was using a soldering iron that was too hot and it was damaging the pots every time. Bought a decent iron and spent the least amount of time possible to solder the pots.
Also used a shielded cable for the pot connections.
Works like a charm now.

Hi guys,

Can anyone tell me which lines I have to change in the SMC code, if I want to use 5 Kohm pots?

Thanx,
George

Hello, thanks for the great work done @RufusDufus , I changed my wiring to work with smc3, everything works fine, the movements are fine but I do not feel the vibrations when stepping on the pianos or the irregularities of the terrain, what should I adjust for this?

Very thanks one more time

Hallo
ik heb een probleem met SMC3Utility alles werkt perfect alle motoren doen het goed, maar in simtools en ik test op as1 als motor1 beweegt en stopt en hij doet niets meer dan ga ik terug na SMC3Utility alles werkt weer perfect ga opnieuw na simtools weer dezelfde motor gaat snel naar 1 kant op -96 en stopt met niets meer doen wat het probleem kan zijn

gr cart

me too. I have the same problem.

Have you resolved the piano vibrations???

Hey
I've tried with these settings [A <Axis1a>] [B <Axis2a>] but he still does not do anything to get what I can do now help me
gr cart

no, I've broken an engine, so until next week the tests are over

no, he roto un motor, así que hasta la semana que viene se acabaron las pruebas

hi everyone
this is my setup i test everything and works ok but without weight, and that's the problem. Whit weight the motors turns and not keep in position. Someone have the same problem ? I change parameters in smc3 utilities but i don't have good results.
this have solution? or i have to change the design of my sim? thanks guys have a nice week

Hey
i have done this setting [A <Axis1a>] [B <Axis2a>] but the motor 1 and motor 2 move but stops and then they do not move anymore than I start smc on they move again during startup smc who can me help out
gr carel

thanks @noorbeast
I really had not thought about that affecting, I will try to make the changes as soon as possible and upload the progress of my project

I still can not understand smc3

What`s the difference setting FPWM at 15khz, 25 khz, etc???
What will be the difference? I´m using wiper motors.
Thanks

Posting this here as well as my build thread since those who watch this thread likely aren't subscribed to my build

Trying to perform the PID tuning tonight using SMC3 setup utility, I'm finding some weird behavior. Sometimes the motors get "stuck" in one position. More details:

• I'm running the monstermotos as a half-bridge (one board per motor) as per the instructions in first page of this thread.
• When it works, it works flawlessly (95% of the time)
• The potentiometer feedback is spot on. Any time the motor moves the feedback graph (green) moves.
• When it stops responding it's usually when I'm just switching to that motor and the target position is a ways away from the feedback position or I've left the motor in one position for a while and manually step the target position a fair ways away from the feedback.
• The utility indicates it's outputting the max PWM and I've confirmed this at the arduino PWM pin as well as the monstermoto contacts using a multimeter.
• The direction output from the arduino seems to be correct (one direction is +5v and the other is zero. These pins swap if I jump the target location over the feedback location but don't go near it)
• The output voltage from the monstermoto at this time is zero.
• The heatsink on the driver does not get warm to the touch at this time.
• To get out of this "stuck" position, if I go to the utility and pull the target postion to the feedback position then away it will eventually start working again.
• Can see this in the posted graph where I pull the target position (blue) towards then away from the actual position (green) multiple times. The first two times don't fix the problem but the third time does and the motor begins following the target position again. It will work again until I leave the motor idle for a while.
• This is happening with both of my motors.

Is this a quirk with manual mode in the utility? Maybe with the monstermoto boards? Any help would be appreciated.
