Greetings; I find I need to issue a blanket thank you to all who have been working on the Documentation.pdf that was installed along with a fresh build of master this morning. I don't know what was left out as its still under 740 pages, but all the gui and remap stuff is much more explanatory than before. As is ways to do a tool changer and its support code, something I have only been contemplating the construction of because its going to require quite a few more i/o pins that just tool & pocket desired. The tool changer needs to be brought into position once the head has been raised. For that I've abandoned the wheel of pockets idea in favor of a chain mounted set of pockets so that the space under the spindle is a bit more open. I have taken to using an impact screwdriver tool on the drawbar, and means to rack it up and down must be devised just to engage it with the drawbar. So theres a signal pin. then 2 more to turn it on in the desired direction. Then a solenoid needs to be designed to lock the quill while the tool is being dropped and the new one brought into position and picked up. And that will need a 10 rev command to find the spindle lock, and some sort of feedback to say lock has been found. Then it gets hairy... A 5i25 simply doesn't have enough pins. So $200 in a 7i90HD and 7i42TA's is next, or some other means of expanding the 5i25 for stuff thats not exactly real time bound. I've bought a 1x4 foot sheet of 1/2 alu for raw material that will be whats left after I make yet another apron for the Sheldon, allowing me to move the Z nut an inch to the right, I'm crushing the Z screws bellows cover enough to jack the carriage out of square when working right at the spindle nose.
So a tip of the old hat to all the contributers to this new set of docs. It should/might/ought to help reduce my often stupid questions. Thanks a bunch. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
