Gene, You should find a lighter spring if possible. I don't think Chris will need the type of probe that you and I have made. To do a "crawling" type of probing algorithm they will require a probe that can side trigger as well.
Chris, I'll have to dig up my notes, but I did come up with a crawling algorithm using a series of short, linear probe moves. However, this needs to be under algorithmic control, since, in this new algorithm, the choice of the next probe direction depends on whether or not there was contact from a previous probe move. This aspect would prevent someone from doing this with g-code alone. Things could be different if the the entire probing operation is wraped up inside emc with a special comand. If the goal is to make a more sophisticated g-code probe command, then it may take some careful thinking to make it generic for all types of machines ----- Original Message ----- From: "Gene Heskett" <[EMAIL PROTECTED]> Subject: Re: [Emc-users] EMC 2.1.5 released > The spring in mine needs about a pound to reach the 0.020" up trip point, > so > that's quite a heavy push in terms of psi at the point considering its > blued > finish I'd rather not damage any worse than it is.
