I want to cut a circular and a square groove, surrounding an array of holes. I can't persuade DeskCNC to make sense of either groove, or to add them to the hole array. It produces lots of complex code for the grooves - what am I doing wrong? The CAD file I'm starting from is "Solitaire 3.dxf", the holes and circular groove are to be 3.5mm deep, with 16mm ball nose end mill, the outer square 2.5mm deep with 6mm ball-nose mill. Disregarding the outer square, I've achieved the intended result by adding code by hand for the circular groove, as with: (Created 21:33:36 27/02/2004 from Solitaire-2.DXF) (Post = FourAxisLinear) (Tool 8 = 16 MM Ball End) N0001 G81 X-90.0000 Y-30.0000 Z-2.5000 R5.0000 F100.00 N0003 Y0.0000 N0005 Y30.0000 N0007 X-60.0000 N0009 Y0.0000 N0011 Y-30.0000 N0013 X-30.0000 N0015 Y-60.0000 N0017 Y-90.0000 N0019 X0.0000 N0021 Y-60.0000 N0023 Y-30.0000 N0025 Y0.0000 N0027 X-30.0000 N0029 Y30.0000 N0031 Y60.0000 N0033 Y90.0000 N0035 X0.0000 N0037 Y60.0000 N0039 Y30.0000 N0041 X30.0000 N0043 Y60.0000 N0045 Y90.0000 N0047 X60.0000 Y30.0000 N0049 Y0.0000 N0051 X30.0000 N0053 Y-30.0000 N0055 Y-60.0000 N0057 Y-90.0000 N0059 X60.0000 Y-30.0000 N0061 X90.0000 N0063 Y0.0000 N0065 Y30.0000 N0067 G00 X90.0000 Y30.0000 U90.0000 V30.0000 N0068 G80 G00 Z6 N000 G00 X0 Y140 N001 G01 Z-2.5 F80.0 N002 G03 X0 Y140 I0 J-140 F80.0 N002 G00 Z6.0 N003 G00 X0 Y0 N004 M05 M02 The last 6 lines I added myself. Line N0067, created by DeskCNC, sends the Z axis up to the limit stop. Why? Removing it removes the problem. I'm new to this game, so happy to be told if I'm doing something wrong <g> Thanks Tim

Change to ISO G-gode post instead of 4 axis linear. Setup-Options-Misc Process each step sequentially, and they will all be within the file when you change to machine mode. You will probably want to Rough only and a single depth for the grooves, with exit, entry, and compensation set to none. Fred Smith - IMService | |||

Fred - Maybe I'm doing something stupid, but I can't get the result Tim was looking for here - i.e., that the central pattern of holes are cut using the drill routine & the outer circle and square cut using contouring, but I can select all of the objects & generate a single program that contourd the lot. Can you be more explicit with the steps involved? | |||

Right Click, Select all Right Click Deselect single, click the two grooves Toolpaths-Drill File-Save toolpaths DNC Right Click Deselect all Right Click Select Single, click the two grooves Toolpaths-Contour Now you have two options: File-Save Toolpaths DNC with Append, File Open DNC to run in Machien Mode or Toolpaths-Run Machine, Save with Append, run the file For Safety, each program segment is always finished with an M02. These should be deleted in the editor if you want to run the entire program sequentially. You can do multiple contour processes if you save before going into Machine mode, but only one if you go direct. Fred Smith - IMService |
