The "fork" came out OK, and some of the parts for the front brake were fine. The top clamp and the belt pulley however got warped at some point during the print and messed up the top layers, but it's good enough for a prototype.
Always fun to see the parts designed in CAD coming to life.

Booked the printers this Wednesday again, so hopefully better luck then. :)

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.

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.

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!

Chris_Beeves

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..

awesome 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...
Monitors are for games; if you want to run a sim, you gotta' be in VR.

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.

Looks great man! Really makes me wish I had a 3d printer.

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

Brilliant work Chris

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..

Just got a 5 year old CTC but she only let me down once but that aint bad for £300!!!

I only do small prints but important ones all big stuff gets laser cut.

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

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
