I am also working in an area with a lot of light so my light source ended up needing to be very close to the bot to be able to see the shadow. I had a hard time seeing the shadow after a solid layer of a dark color. And I used tape to hold the paperclip in place but in hindsight that probably made the paperclip slowly drift as the tape settled so to speak. 

I have a precision egg coupler but I haven’t opened it simply because I haven’t felt I needed to yet. It only takes me about 40s to get the egg in the coupler well and I don’t think I’ve had any issues with slipping. I will be switching to the precision coupler once my engraver gets here today and I start working on glass.

I drew lines on the feet of my eggbot and on the table so that if I bumped the bot I can easily find the spot it was in before. The “imponator effect” was new to me. I had to look it up … but thank you for the compliment! :D

I love the idea of that handle on the center shaft. Great mock-up of this problem for future users! :)

Your method of using two shadows and a pointed light does indeed solve my issue. However, I found this method particularly finicky and I kept bumping the paperclip while trying to adjust things.

I’ve rigged up a way to use a cheap laser pointer to align the pen:

I have it hooked up to a switch so that I can turn it on and off without disturbing the lasers position.

Nice! That is clever! I will give it a shot a little later today.

To get your images to display you simply have to make sure the link goes to nothing but the image. When you go to that dropbox image it actually goes to a webpage containing the image and a download button. Dropbox doesn’t make it easy to get to the direct url, but if you go html snooping you can find it:

I’d just upload them somewhere else, like imgur.com – just make sure you copy the direct url (they will give it to you on the right side of their website after uploading) and paste it in the image embed box.

It does feel solid … I will try to adjust my egg arm and see if that is causing it.

I was thinking, could it also be how I have zip tied motor 2’s wire?

I know from my 3d printer that these servo motors can cause a lot of inductance – but can it affect itself?
