Greetings all; I found I have a 4mm mill, which will give a closer match to the rounded corner radius of the db pattern.
In laying out the cuts to do a db25 length pattern, I am mirroring 1/2 of the max overall length of of the wider top, which is 1.537" including the tool diameter of 0.157480314961 that needs to be subtracted from that overall length. So thats [[1.537-0.157480314961]/2] to get a measurement left and right and of the geometric the center of the pattern. That move is to be done by adding 1/2 the dsubs height(0.334"/2=.167)-tool_rad(0.0787401574803) to its current centerline height for that 1st move. That move will also include the Z decrement since this panel is plenty thick enough to deflect the tool, so I am climb cutting (ccw around the inside of the desired pattern, while digging progressive deeper. Then the mechanical pattern from there to the lower left end/side isn't speced in run length, this shorter run isn't specified except as a 10 degree angle. With the tool stopping at the mirror of the prior y height. How do I calculate that x offset from the x=0 centerline for the -target of that end move? which then turns in the + x target for the next move, and the a move back to the starting point which will then be done at the mirror of the first 10 degree angle. What I want to do is pass 4 vars to the CALL driving the machine to the center of any hole (11 needed), finish the move to the edge of the hole by adding all the little offsets used to those 4 values passed as arguments to the sub that does the work. I broke a 3rd .125 mill and bent a fixture bolt last night trying to carve it again because I'd missed a g54 insurance call on a restart. Thats fixed now, but this is getting old and ex$pensive. And I've decided to make 2 of these so I can put the 2nd one on this mill, along with another 15 volts of stepper motor voltage. That of course will then lead to the stripping the gear box off it and mounting the 400 watt spindle motor from the 7x12 (TLM's former spindle motor), and about a 3x1 spindle speedup, an encoder and a better mister. If the bigger motor kills the controller I've already souped up with a much heavier hexfet, shrug. I'll send Jon some more green to make me another of his. They work VERY nice for spindle control. :) Thanks all for any help with the math. And have a Merry Christmas. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
