Greetings all; A couple of question regarding the math used in gcode handling.
1. What is the best way to turn a positive value into its exact negative? I find constructs like g0x-[#<_var>] are rejected out of hand, but its seems like there ought to be a better way than #<_var-minus> = [[#<_var>] - [[#<_var>] + [#<_var>]]] On a separate, confusing the issue line. 2. Using G2 the preferred way seems well nigh impossible, with or without using arcbuddy.py. However, since the radius mode, which isn't well liked, works from where its at ,to where you want it to go, with nothing more than X Y & the radius R, it is much easier to make it draw the curves I want. In the present case, it is not going to be crossing any of the target location points at anything but perpendicular to one or the other of X,Y. Does that largely eliminate the objections involving its accuracy at 0,90,180,270 on the compass? I received that die grinder from HF today, finished the mounting on my mill, and have shaved the end of a short stick of white ash just to see what sort of a finish it will leave on the shoulders of a tenon carved with it. Absolutely beautiful, I could silver the end of the stick and use it for a shaving mirror, not a single loose hair of wood anyplace on any edge, even if the cut is a dig cut, but I am using climb because the bits edge at the point of the cut, is cutting into the wood, not out of it. I'll have a few pix added to my emc subpage by tomorrow I hope. Thanks for any enlightenment. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
