Re: 90 ton 1/14 metal excavator scratch build w/embedded PC
Yes, true, I just thought the 3kg would be less violent when it engages. It should probably be a pulling spring instead of a pushing spring so that the backlash is only seen when pushing hard with the stick and not when pulling hard. I'll see what I can do about it.
I also found that the set screw was loose, so the backlash is only about half of what you see in the video when the set screw is tight.
I have done a few things that I haven't documented here yet. The gas spring on the stick, a gas spring on the bucket, a mount for the CPU (the Raspberry Pi) and angle sensors for the bucket and stick. I'll get those updates up here shortly. :-)
