Greetings; What arc mode, absolute or incremental, does arcbuddy's answers come out in?
I have the default incremental arc mode set into in the code. So, needing a 45 degree arc, in ccw direction, with an arc diameter of .275 (twice the #<_corner_rad> I use elsewhere in the code to stop a run short, leaving room for the arc), giving an x center offset of -#<_corner_rad>, arcbuddy spits out a G3 string that looks like it should work, but obviously I'm not groking it all. I am at the end of a Y move thats about an inch above the origin 0.0000 for Y. X is at key_w_end=0.7500 In arcbuddy, X center of arc is set -0.1375, eg half the diameter. Y center is set 0.0000, where its at in incremental mode. Diameter is set 0.275. Start angle 0.0000. End angle 45.0000. Starting X,Y says 0.0000 for both when show me has been clicked. The G3 arc line, entered in my code: G3 X-0.0403 Y0.0972 I-0.1375 J-0.0000 Thats in incremental mode And LCNC yells its off more than 87%. I'd copy/paste the error box but it can't be done. Again using arcbuddy.py, the upper right 90 degree corner: X center = -0.1375 from where its at, Y center =0.0000 (where its at) dia=.2750 start x,y=0.0000 G3 X-0.1375 Y0.1375 I-0.1375 J-0.0000 And LCNC says its off 95+% !! What the heck am I doing wrong? This same arcbuddy gave me a G3 line for the lower right 90 degree arc ( using 270.0000 to 0.0000) corner, ccw, that worked the first time.
