FINISHED! - 2DOF Wormgear Race Simulator by Arno

[dearn]

Thanks guys for the information. Seems to be that I'm to carefull with my JRK's

This weekend I have some time to play with configs and will try some things out.

Big kick! I am just moved to a new home. The sim is working again with new PID settings and the big PSU's @ 33AMPS a JRK.

I need to find some time to do a massive update here.

Can you post one quick update of what PID youre using?

I never managed to get my ZYT90 to work with JRKs, too much errors..

Any new updates/photos?

I'm really liking your build and it is giving me great ideas, keep up the awesome work!

Jep, are coming in this week!

Finally here it is, THE update. I have found some time to make a short movie and get all the pictures from the "archive".

I will start right away, I have moved out to a new house, so i had to take the racer apart. This was no problem because 1 of the PSU was blown and the frame had to be powdercoated.

I started to paint the wood:




Next, i send out the metal parts to be powdercoated in black, it came out very nice!










Mounted the rails for the seat:


I also made a dashboard with a Arduino an TM1638:




The connectors had to be re-solderd to the back:










And covered by some carbon wrap:




Next the PSU's. I have bought some new ones from eBay. These ones have 50AH each(!), a total of about 1200watts to power the wormgears and JRK's.


I made a stop for the engines, so it can''t be out of range again. This was happening when a person was stepping on of off the platform








Almost finished!






Total view:




It is a very stable platform.

Many of you asked me what the configuration is because of the big wormgear motors. Here you will find my current (and best) config for the JRK's:
PID settings:
Proportional Coefficient:
5/4 = 0.31250

Integral Coefficient:
13/11 = 0.00635

Derivative Coefficient:
50/3 = 6.25

PID period (ms): 5
Integral limit: 1000
Feedback dead zone: 2

Motor settings:
PWM frequency: 20kHz
Max. duty cycle: 350
Max. acceleration: 350
Bake duration (ms): 0
Max. current (A): 37.995
Current calibration: 149

Max. duty cycly while feedback is out of range: 350

When motor is off: Brake

I also made a short movie to see the racer in action.

Thanks you all for your advice and help! Also a big thanks to X-SIM software and http://www.ArcadeWinkel.nl

Any one an idea how to include the Youtube as a iframe?

Well done Dearn!
Very nice post

I think you have to remove the 's' from https://

Thanks RacingMat!

Movie is working indeed.
