@tutley Have you noticed any issues with the worm gears on the pumps with the alphas? If you have not, then I'm gonna go ahead and confirm the spacing as good.

I didn't notice any issues with drag from the current spacing of the worm gears so i am going to go ahead and pass this on to @Steven for now and we can return to this if we get an issue.

Ready to be merged to master.

I have not noticed any issues. I think we will want to add some form of lubricant to these gears for beta/production units as these gears sometimes squeek on retractions

@tutley I was going to ask about that actually. What would you think about using an aerosol white lithium?

The worm gear is carbon steel and the worm wheel is bronze. Lithuim grease should be fine for these gears!

This is now merged into master. @logan assigning this to you to continue tracking the lithium grease. Can you please close this if that works well?

@Steven Will do, thanks!
