Raceflight V2

[Bruceaust]

This is an updated resume of what I have achieved so far.

Some of the relevent information has been reposted from the old Xsim2 site.
I started out designing a steel frame "joy rider". This design has now been morphed into a hybrid system that draws ideas from a number of configurations found on these forums and elsewhere on the internet.


Thanks to those who share their ideas and enrich everyones knowledge.

Construction finished, just need to get the motion going.

(Thanks Deriy for the seat design)

Turn down the thickness of the bolt head so that it can be "melted' into the plastic gear.( heat bolt head with a small butane torch)
Hold the bolt in the the lathe tailstock chuck to produce a perfect alignment to the gear shaft.

push the hot bolt head into the gear with the tailstock chuck

Turn the face flush under the bolt head to restore the "bearing" face

Drill a hole in the motor cover plate using the lathe.
The reassemble the motor so that the bolt protrudes through the motor cover plate.

Make a mounting bracket to hold the feedback pot in allignment with the motor shaft

Good work in general I also like to congratulate you as the potentiometers located on the engine

In the process of fitting Limit switches to both X and Y Axis. I am wiring the switches to control a contactor. The limit switches are wired in series with a toggle switch that controls the contactor, so that the 12v supplies to the input of the H bridge can be isolated manually as well as by the limit switches.

Oh well
Had limited success testing the motion.
The AVR/Hbridge worked ok, except I overheated and blew a couple of Fets in the Hbridge.
I think I am trying to move to much mass to quickly, or the Hbridge is not able to supply enough current when
the wiper is struggling to move.

I will need to re-think my motor/motor driver options.

Nice to get it moving though!

Ouch! Always a pain if something breaks

But like you said, I think you are indeed expecting a bit too much from your motors.

Nevertheless congrats on getting it moving!
