Finally got the new belt pulley printed! Fits perfect, and the belt tensioner works just as planned. Hopefully it will all handle the torque..

Also designed a little holder for the STM and motor driver.
Now it's not long until testing!
Fingers crossed the new microcontrollers do the job (and that they show up soon)

Got two new fork legs in the printer right now. I'm color blind, but even I can see that "mystic green" doesn't fit very well with Ferrari red and yellow ;) Unfortunately I cant get Öhlins gold filament..

This is so much fun :D

Not bad at all!
Nothing much happened the last few years for consumer printers. They're still automated glue guns ;)

Swear by my 3D printer makes so much possible


Thanks DD!
What printer do you use?

Printing a new 95 tooth belt pulley and a microcontroller/motor driver mount tomorrow. Fingers crossed again.

Had some time to work with the stm32 microcontroller today, and it seems I got a bad one.. Windows won't recognize it, so I ordered two new ones. Hopefully at least one of them will do the job! Otherwise I'll have to switch back to the slower arduinos..

Thanks! Yeah, it's magic for prototyping. When it works. ;)

Quote from: ainuke on March 01, 2020, 09:02:43 PMawesome looking rig!

can you be specific about the motor/driver combo you're using and how much torque you're expecting?

also, I'm interested in learning about the ffb you're using; more for another project I'm working on (FFB joystick for combat flight sims). You're using the Leonardo for processing this? Where can I read more about this, specifically as relates to gaming contollers? (My skillset lies more in mechanical design/prototyping than software, so looking for easier solutions).

Following this thread now...

Thanks! :D

The motor I just got because it looked strong, but after testing it I just think it's heavy ;)
I'll be using a BTS7960B driver to start with, should be plenty for this 120W motor. On paper I'll be getting something in the 2-4Nm area, so probably about 2Nm..
To accurately simulate a motorcycle, I'll be needing a lot more than that (probably in the 10Nm area), but that's another build. I have a "hoverboard" brushless motor waiting for that.

I'll be running EMC on an STM32 "black pill". There are perhaps better options, but EMC is quite easy to use.

I don't know how well the wheel firmware would translate to a joystick, it only offers ffb to the steering axis.
Xsimulator.net has a lot of info regarding "diy peripherals", I'd give it a read.

Cool, hadn't seen your dash either!
Hats' off!

Hahaa, a wonderful little piece of ingenuity! Good job!
What did you end up using? Udp or HID?

Quote from: PiBoSo on April 28, 2013, 08:53:51 PMLike in "directsteer=1" mode, it is possible to set the proportional and derivative controller parameters adding a file named "directsteer.cfg" in the bike folder.
The only difference is that the "torque" section is ignored.

What does this mean in-game?
P: A higher number means more sensitive to the difference between in and out value? A lower number smoother and "slower"?

D: Anticipation of what is to come, but how would that effect the actual steering?

These settings will be helpful when trying to tune in the "feel" of a bike (big&heavy or light&fast) or help making directsteer easier to use?

Fourth try was successful!
Next step is to make the top and bottom plate and assemble.
I also need to figure out a good table mount..

Printed the Quick Release today and it turned out great!

And got the fourth try of the top clamp on the printer right now.. Fingers crossed!

Been waiting for a follow up!

Have you continued developing the rig?

The third print had failed too.. Printed 12 hours, then just stopped.. At it again!
Took the opportunity to redesign so I can have a quick release system for the handlebars to easily be switched to a steering wheel.

Bad luck this time too! The filament got stuck in the very end and the print was stopped. Bearing brackets, load cell holder and a 100 tooth belt pulley came out great though, so I just need to redo a few parts.

Load cell front brake bracket:

I'll probably go for a hydraulic system in the future, but this wire solution actually gives quite a good feel. Nice blend between firm and flexy.

How's it going Poupou? Progress?
