The first test of the LitePlacer retrofitted with ODrive motors was a success!

Running at 40% speed limit and 25% current limit, reaching a top speed of 1.75 m/s. The motor that is currently on the LitePlacer was picked for a system running on 24V, but this test was run on 12V, hence the low speed limit. I have ordered a 24V power supply, so hopefully we can see it go twice as fast soon!

It should be noted that it is possible to pick a motor with twice the kv rating to run on a 12V system, and it would perform respectably.

LitePlacer build

The LitePlacer comes in a kit, which took about 2 days to build. Below follows the build in pictures.

Here is an empty table; this is where we start. It is where the LitePlacer will be bolted. I chose to get a sturdy table but it still wobbles with the very high accelerations.

A box full of goodies!

Here is everything in the kit, splayed out on the floor, and somewhat organised by type of part. If you are building the kit, I would recommend also sorting the bolts by size, which I did later on.

The build instructions are very well done, with everything detailed in bite sized build steps. A significant time of the build is spent collecting the components for each step. So if you have an assistant, have them help you collect parts for the build steps. Above is our assembly line at one point.

Here is the z-axis (with the lead screw and rails), rotation axis, and the pick mechanism.

Here is the x-axis finished.

Retrofitting the y-transmission with a Turnigy Aerodrive SK3 - 5065-275kv. Calculations show that it is vastly overpowered for this application. Just the way a demo should be.
