Greetings all; The Tormach ER20 adaptor will be more than enough extension to clear everything, so that problem is solved, and I am about to go carve up a kilobucks worth of Mahogany. But I was unable to come up with a fly cutter to level the addition to the front of the jig, so that needs to be addressed before I actually mount a piece of Mahogany into it.
I punched a small hole in a contact piece of PCB on my jig yesterday, and I want to see if I can come up with a "g53 g1 f20 xn yn zn" command that will put the machine in a position to find, by G38.2 means the contact references on the jig, from which all other moves are then referenced. I intend to leave the G54 mapping untouched from that determined when the machine is homed. My code is not now doing that, so a rerun finds the default G54 map AFU on the 2nd run after the tool change. Hence the damage to the contact, but its slightly over an inch square so I'll just move it 50 thou to an undamaged spot. BTDT on the toy mill too. And to make all the other moves from settings done in the G10 L2 P2 #x #y #z using G55 mapping. This so that I can reload the routine after setting a trigger variable to tell it I have changed tools and that the exact same code can be re-used, but with a tool_diameter of perhaps .005" and a reduced to single pass depth cut nominally 0.125" below the top of the board. The tool change is from a .250" end mill, to a sharp pointed 1/8" radius roundover shape. So the tool_diameter becomes the diameter of the tip, quite sharp. The depth of cut is then such that the outside wing of the roundover is right at the surface of the board. Am I on the right track if its homed when I run it the first time, to do this initial move to the contact points on the jig using the G53 G1 F20 x# y# G53 G1 z# to drop the tool near the contacts Then, still adjusting only G55 with a G10 L2 P2 #x|#y|#z as the G38.2's run, using the results in the #53xx array to reset G10 L2 p2 (G55) and then doing the rest of the routine in G55 mapping. Will this be repeatable over multi-runs without all that re-homing by switching back to G54 for those moves on pass/tool 2? I think one of the mistakes in my code is the modifying the G10 L2 P1 (G54) mapping, which for repeat runs is doing an AFU to where the machine goes as the original home position has been destroyed by diddling with the G54 mapping. I'll march thru it come daylight and fix that. Am I making sense? I had thought a G92.1 wouild cause a restore, but that doesn't appear to be a solution. I doubt if I fully understand what it actually does. =====================new subject===================== Also, there is not a tool image for the backplot that would represent this tool, that I know of, unless the tool table has grown the ability to specify a suitable image as opposed to the tool diameter cylinder it uses now. Wishfull thinking? Future feature perhaps? Thanks all. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
