Simulator rig with ODrive


#41

Hi,
yes I could share the CAD datas, but it’s very special. It fits only to this kind of motor and the aluminium frame. Therefore I will wait with sharing till my prototype is working.

Yor second question:
I have designed a 3d printing part thats squizes O-rings inside the carbon tube. Don’t know if this will be enough.

The other side at the ball screw nut has to be glued. 3M 2216 is the best but extremly expensive. UHU endfest could be an alternative.

Hi all, time for an update.

And the base chassis

Now waiting for:

  1. limit/home switch firmware
  2. CFK tube for the second actuator

Hi,

Nice little update. I actualy meant the ODrive casing.

Ah, OK
If I find some additional time, I will remove the Zennix and share it.

New Update:

placing a anti shaking ring to the ball screw.

I decide to change the powersupply to DELL server PSUs. Each offers 12V and 53A. To put it serial for 36 Volt I had to disconnect the AC ground and the DC ground. Otherwise :boom:
Additional I connected a LM34 to the fan control line so it runs depending on the temperatur. Next was a relais to switch all three on together.

Hi,
It’s me again, I don’t think the ring will last long, I have been thinking about other ways to do it, bit I haven’t found a better solution.

The power supply’s are not for only 1 motor right?

Cheers Stijn

Hi Stijn,
power supply for one ODrive with two motors.

Time for an update.

The missing parts have arrieved.

First Actuator is completed. Second is 90%. Need it for testing without transmission belt. So mistakes cannot crash it.

Finally I’m waiting for the firmware with endstops.
