Re: [Emc-users] Following error only on jog
Problem solved, Thank you! Regards! Hi See Integrator Manual Chap 4.2.8 In [TRAJ] section of ini file, set DEFAULT_VELOCITY= DEFAULT_ACCELERATION= to figures far lower than your current MAX figures (1/4 at least) and experiment from there Acceleration is the one which causes the problems normally, when moves are activated by key press, especially if a momentary contact. regards -- Ridiculously easy VDI.

On Saturday, December 31, 2011 01:48:48 PM Terry Christophersen did opine: .125dia tool cutting a .230dia ID will leave you .0525 move if you are starting in the center of the hole and moving to the edge This is I believe the crux of the problem. This code generator does not start at the center, but pre-places the bit at the +x starting position, then issues about 15 to 20 lines of code to cut short segments of the circle, using g2 moves. So, according to the backtrace anyway, I see a slight 'hook' in the trace (when it actually gets that far) as it starts the cut, then errors because its gouging. I dont know if you are saying that cuttercomp is not working correctly but I have used it for this application and it works as I think it should. So have I Terry, but this is a fresh emc release as I'm on 10.04 and synaptic is setup to keep me up to the latest release, 2.4.7-11-g7a74494 as of a couple days ago. So I am wondering if I've found a regression. My point is, that there are moves ahead of the g2 moves that it could use to apply this cutter compensation, but it apparently waits until a g2 move is commanded before it gets applied. And IMO that is WRONG. It isn't helped a bit (in my ancient mind) that the descriptions for the G41-G42 commands make no mention of dig cut or climb cut, just left or right. I could understand the concept a lot easier if it were to deal with it in dig or climb terms. Here, its all dig, it drops the bit in, and the end result is a full clockwise circle move with the bit, starting and ending at the 3 oclock position. So if I want to use this code to just isolate the screws, I'll have to forget G41 entirely, and put in the engraving bit just dig the line a thou or so deep. That will work to isolate the mounting screws, but I had visions of setting the area inside the circle down 15 thou or so because 1/4 screws are not quite as long as need be for the end of the screw to come flush with the nut. So I may as well take the code that bored the dozen holes and write a new subroutine to do this. Its amazing the stuff we put up with at the feet of the do it with a computer god. Anyway, its new years eve and I intend to have this stage done by the time we grab some snack stuff out of the fridge go down the street to the neighbors for watching the ball fall or whatever.

On Saturday, December 31, 2011 03:38:48 PM Terry Christophersen did opine: Your New Years eve sounds as exciting as mine ROTFL! But, I can remember 50 or 60 years back, doing New Years Eve up right. But for the life of me, I can't remember why... I am running some small parts on my Hardinge--its not so bad though 1 bar of material runs for a hour or so. All this is to be able to cnc my little toy lathe. But I don't have any collets for it, mostly because I haven't make a bolt to run the #2's I have for that toy mill. So that largely precludes any sort of controlled step and repeat, lights out production run till its out of round stock here. The gizmo I want to make is only an inch long anyway, so its open the jaws, slide it out (and having it under cnc means I can slide it out to touch the bit in a known position) then fiddle with the dial indicator getting the workpiece centered again, for every part I'd make. But even that would be a hell of an improvement. Precise and a 7x10 should NOT be discussed in the same room. Too much rubber in the tool post insufficient ponies in the motor among other things. Fine feed cuts at about .0015/rev are about all it can muster in low gear, 500 rpm, and a 1 diameter workpiece. 2.5 in alu needs hand help. Plumb Puny. But, if this can be made to go through the motions, maybe make a dozen parts, then doing it to a grizzly G9972Z gets much more appealing. And of course it all depends on me lasting long enough to do it and enjoy it. At 77 diabetic, my warranty expired decades ago. :-\ Dont have too much fun with the Jack That's why I think it will be saved for more mundane times, like around the campfire in the neighbors back yard while we try to solve the worlds problems with our own 4 hands.
