Adventures in RepStrapping: Day 4
And below is a pic of Lamarck as he stands right now:
He's a handsome enough fellow, but without any brains he's just not very useful at the moment. Thanks to the support of those on the forums and IRC who are giving me advice on the comms issue, I will hopefully have the brains working soon, and Lamarck will be able to make himself useful. :)
Those spray cleaner bottles are a good source of small, powerful springs if there's a shortage of suppliers in your area. I've actually switched to using several split-washers interspersed with ordinary washers.
Otherwise you end up with the spring compressed to the max, thus giving it little play to take up slack.
As soon as I'm printing things reliably I'm going to modify the Mk II design so that the bolts are maybe M5 or an American equivalent of perhaps 1/8 inch diameter. I can get some seriously stiff springs at that diameter. These #40 springs are just too small to be much use.
