Hi, after discovering qpocket.ngc I got curious about that stuff and digged all related docs I found. But docs are quite rare on that subject. Found O-codes and ngcgui ...
In the helpfile ngcgui a gcode-meta-compiler is mentioned and that help will be provided at command line ... ... but in master there is no executable called gcmc. So docs outdated? Or gcmc missing? What is exactly the role of gcmc? Is there a howto on how to write files like those from nc_files/ngcgui_lib? Than I scratched the list of canned cyles. Where can I find the code for i.e. G73? Is it possible to write own canned cycles? Reading docs of G73 put me hairrising. Is that doc right? In point 1 (preliminary motion) it is stated: "if the current Z-position is BELOW the R position, the Z axis does a rapid move to the R-position" On my machine the opposite is true and quite common used: i.e. on pieces with trunnion, I position the tool tip above the top surface of the trunnion. To drill a hole aside the trunnion, the bottom of the trunnion is Z=0 - assuming the trunnion has a height of 50mm I position the tooltip at Z=55 To drill a hole with 20mm depth, I code G73 Z-20 and use R as safety height - in this case R2 which leads to G73 Z-20 R2 The tooltip then does a fast move from Z55 to Z2 or in words: from above the R-value to the R-value. Of cause, my machine does a fast move too, if tooltip is below the R-value, but I can't imagine a situation, where I would like to code such a thing. In chapter 2 of O-codes it is stated, that comments after an O-word should be avoided. ... but 3.1 shows Fanuc-style programs, where the program title is just a comment after an O-code. That commentstyle title is quite handy, as it is displayed in filemanager. So is Fanuc-style title supported, allowed or tolerated?
