hello 
there is a problem with parametric codes, especially for 3d toolpaths with high resolution
code shared by mcode at post #8 is a linear type : performs the best
2nd code shared at post #12 is a parametric type : allows fast code iterations, but may lead to downtime, depending on how the controller handles the calculations inside the loop + how the code is written
the downtime is lower than 0.1seconds ( perhaps even 0.01 ), but it simply sums up at each loop, and in the end, the cycle time may be signifiant longer
this post is about downtime elimination for parametric codes, so to make them perform as fast as linear codes : goal is to keep the parametric advantage without cycle downtime
this will allow rendering fast different toolpaths near the machine, and this is faster than going at the pc and changing the CAM parameters + sending the code to the cnc
after a few trials with the parametric code, there should be a nice operation output; now, when the operation looks nice, the parametric code should be run again including a data-output soubroutine
data output can be done in ( at least ) 2 ways :
... coordinate output : x_value y_value z_value
... G-code output : ... G01 X = x_value Y = y_value Z = z_value
about the codes that will be shared in this post :
... 1st one is a parametric code that outputs data : coordinates ( ODD1 ) and G-code ( ODD2 )
... 2nd one reads the coordinates, outputed by ODD1 , and generates the movement into the cnc
... 3rd one is edited : inside it is pasted the code outputed by ODD2
attached file " coords-odd1.txt " was created by ODD1 soubroutine
attached file " coords-odd2.txt " was created by ODD1 soubroutine
about execution times :
... parametric without data output : 37286ms
... parametric with data output : 39883ms ( a bit longer, of course )
... 2nd program : 40937ms ( it is even longer, because is harder to read data than to write it )
... 3rd program : 37280ms ( same as the parametric without data outputs )
if possible, is preferable to write a parametric code that performs as fast as a G-code
