Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

The only way to have full resolution of the ADC (analog to digital) is to ensure full travel on your pot.

So you can either:
1) make your rods smaller (for example 50mm shortened to 40 mm)...
This way, full pot rotation gives you less simulator travel but motor rotation stays the same.
(I suggest the first option)

Or
2) use proper gears to change the pot to motor rotation ratio.
This way you reduce your motor rotation and thus your simulator travel the more you change this ratio.
If this second solution changes your motor rotation to be no less than +/- 45 degrees from resting position then it may work too. I dont suggest Less than +/-45 degrees of motor travel.

Dear @insanegr if you use a smaller range of the pots (f. eg 100 degrees instead of 180 degrees) you get a worse resolution! So I suggest always to reach the max and use gears if needed

thanks for your answers @pipis2015 @Pit .
need to find some gears and put them on my pots.

What is difference from 4DOF?

Pardon? Could you describe it more exactly?

Sub thread ...
Easy adjusting the Max limit and Clip input with "Motors POWER OFF " just using the Arduino and the feedback pot signal :

• Taking advantage of the feedback signal as a guide where the platform is located now ... Manually move motor 1 UP or DOWN through the working area to the maximum allowable ... leaving a small mechanical operating safe zone from the actual platform damage point ...
• Open the SMC3 Util and you'll notice that the feedback green line is moving toward that maximum allowable working position .
• Then use that position point in the Util. as a guide to adjust and place the Clip input Orange line exactly as the same place as the green line ... that's where the motor will receive a PWMrev reversing command .
• Then slowly move the platform little forward toward that safe zone and stop just before platform damage point ... where actually you don't want motors to go further ... then place the Max Limit Red line so as the green line position has touched the red line by now you'll notice that in SMC3 Util. motor 1 is = > OFF .
• Use the +- small 1 step to accurately do that alignment .
• Go back manually reverse to the maximum opposite side and verify & match these limit lines are positioned at the same points for the other mechanical allowed safe zone and damage stop point .
• As in SMC3Util. both side limits has the same values thus the working area should be really centered ... IF COULD NOT ACHIEVED ... Use whatever the biggest values found for these limits [ the closer to the center ] .
• Go back manually near to center position for this motor ...
• Perform the previous steps for each motor ...
• Finally Turn ON motors power s and manual mode mouse click center the platform electrically .
• Enjoy .

Boa tarde! @RufusDufus , @eaorobbie

Rápido rápido Você poderia Fazer hum código Para Que POSSA USAR ESSE tipo de Cartão?
ESTA placa E fabricado Aqui no Brasil, eu ficaria grato se Muito Alguém escrever hum código Para Que eu USAR com placa Arduino, SMC3, Blackmoon.
Envie o manual do fazer que eles possam analisar Paragrafo agradecimento [Anexar = full] 26027 [/ attach]

@Claudemir you have to add a "@" like @RufusDufus

Saudações BR, a codificação terá a mesma logica que a utilização para Arduíno e ponte H, agora se diz a respeito de não utilizar um intermediário?

Você fabrica a placa, já tens simulador?

Translator
Greetings BR, encoding will have the same logic that the use for Arduino and H bridge, now says about not using an intermediary?

You manufacture the plate, already have simulator?

yes i have a simulator!
but Chinese H bridge do not support the weight. Blackmoon have these plates but I can not code in order to use them!

Qual modelo utiliza?

Eu uso um chinesa e uma própria com CI 31 e 32

__________________________________________

Which model to use?
I use a Chinese and an own CI with 31 and 32

I tested Mode2, and used two 400W motors, and then my IBT-2 is broken.
Although IBT-2's rated current is 43A, logically speaking, there is no problem to drive 450w(less than 12V×43A=516W) motor, but my IBT-2 is broken.
Fortunately, I found the designer of IBT-2 in the Internet. According to him, IBT-2 is designed for 80W window lifts motors, and 43A is not IBT-2's rated current, IBT-2 can't work for a long time in 43A.

Thank you for sharing. BTW this is not new, the ibt-2 is a relative weak motor driver.

Thanks Rufus Rufus work!
Problems I found while testing, I hope you can help me analyze the reasons about problems，Thanks！
For ease of explanation problem I made two pictures:
win8.1 x64
SimTools_v1.3
1. Use SMC3 output test, the motor is working properly.
Please Note: The slider position corresponding to the position of rotation of the motor


2. Use SimTools output test, the motor does not work properly.
Please Note: The slider position corresponding to the position of rotation of the motor

In the SMC3, the computer drive your motors to do triangle wave motion , so they will work smoothly and properly,
and in the SimTools ,your motors to do triangle wave motion in manual, so they work bad.

Thanks you
Used to manually adjust the test
SMC3 move the slider, the motor rotation will correspond to the correct position with the slider.
SimTools move the slider, the motor rotational position corresponding to the position with the slider is wrong

Try lower fpids f.eg. 2 or 3 and lower fpwm like 25hz

Thank you!
I try to change the settings, but the problem remains.（Try lower fpids f.eg. 2 or 3 and lower fpwm like 25hz）
I also add a caption.
Please note: the slider position corresponding to the position of rotation of the motor.

Could you try in Simtools the axis output and not the force output. thanks
