  1. yes, choose the line , hit RMB (Right Mouse Button) and choosing one of the three colors for wireframe, surf or solid will change the color of the line. Another method would be to choose Analyze and change the color from there, RMB is more natural and the designed method for color control in 2019.. Gracjan

    New Mikron

    This is not my opinion , as to have an opinion one would have to have a good practical knowledge of what one is saying (I only know HH very well) , but someone once wrote on the CNC - arena that Heidehain is the ideal control for a 5-axis machine. With other widely used controls , not so much... Gracjan

    In my opinion you will be thoroughly amazed by the Heidenhain control. Yes , the code looks a bit different, but otherwise , pure pleasure to use. Gracjan

    This number changing was only a thing in X9 . After that came Mcam 2017 and then all the bets were off again. Gracjan
  5. Usually this happens when you are extruding splines.... When a spline has a large point count , I don't know the head count above which the parasolid kernel produces these facets. Usually I reduce the number of points in a curve using Wireframe/Refit Spline to reduce the point count. But since you say that an analysis of the curve yields an arc as an answer, I'm a little stumped.... posting a file would help to help Gracjan

    Rookie Mistake

    #variable definitions swcs_name : "" #PRM20014 swcs_name1 : "" swcs_name2 : "" # to check if there are different WCS's , they should all be the same fq 53 swcs_name2 "OOPS , rogue WCS in your program!!!! " pparameter$ # Initialize variables, and Run parameter table if prmcode$ = 20014 , swcs_name = sparameter$ #WCS name pheader$ swcs_name1 = ucase(swcs_name) ptlchg0$ # Null tool change swcs_name2 = ucase(swcs_name) if swcs_name2 <> swcs_name1 , q53 ptlchg$ swcs_name2 = ucase(swcs_name) if swcs_name2 <> swcs_name1 , q53 very basic stuff for anybody who dabbles in posts Gracjan

    Rookie Mistake

    In the case you presented you could have the built in warning system of checking the WCS , but since you know that it's OK, you get warned by the post , but post it out anyway knowing all is fine in THIS CASE . it*s the 50 ops where one is programmed with a different WCS than all the rest that will overwhelm You , that's where my WCS check would be worthwhile ...

    Rookie Mistake

    I would say that a demand that all the WCSs in an NC-program are identical is a pretty universal demand. So why not make your post check that all your WCSs are the same as the one specified in the first operation ? That takes you out of the check loop. I have been doing that now for many years. Gracjan
  9. jlw , wanted more info about setting up the post , so here it goes : it's a table - table , with the B-axis vector always provided by DMG as in the picture: other than that , nothing special about setting up a post for it .
  10. So it turned out that my C-150 was just one special solution for one problem , but it would not have worked in general. It turned out that by tweaking two parameters in my Camaix post I was able to output the right angles without the C shift . Gracjan
  11. So , did not get an answer here , I will have to continue my snooping work the next time a 5-axis (M128) case comes around . .... Gracjan
  12. So many answers I have to give here.... Actually , I was hoping to get an answer from my esteemed colleagues Greg Williams : "this value of -150 gets added to every C axis output." . This is the definition of a shift . We are of course talking of a rotary shift. If you mean that I could get the shift done on the control , yes I could do that probably with a Cycle Def 7.0 Datum Shift , C-150 command . The result would be the same. However , if for some reason the operator would negate the command we'd get a crash... mkd : yes it is a Heidenhain control on this machine. I was referring to machining when RTCP is turned on (M128). The plane spatial/Cycle 19 works fine , as I can sidestep the issue of outputting the B-angle by outputting the A and C angles. The machine will calculate the right B angle based on A . JLW: I will slam dunk this probably today. I will measure the position of a hole on the outer axis of the the table ( for max angular precision) in 3-axis mode and the I will position a gauge above the hole in RTCP /M128 /5-axis mode and see if the positions aline . I realize this is a reverse engineering approach, but it's one that will get me close to the end result and that will give me time to ask around/figure it out , whilst the customer is chugging away on his new DMU-60 evo
  13. Seems like gcode is responsible for the 670 evo . It is , I say again DMU 60 evo. Gracjan
  14. I just realized that the heading is WRONG IT SHOULD BE DMU 60 EVO well anyways back to the subject... and this is the result on the machine , or in laymen terms , all is fine. the axis of the tool intersects the axis of the cental hole of the part , etc..... Gracjan
  15. So , in order for a post to work properly for this machine ,these vectors have to be input : 1. The vector of the spindle 0,0,1 2. The vector of the variable rot. axis (C) 0,0,1 3. For my machine ( these values will slightly differ from machine to machine ) 0.5849.... , -.5735..., 0.5735... which is 44.6 degs from TOP and 44.6 degs from FRONT with these values I tried to machine the chamfer on the part , the axis of the tool pointing towards the center and this is what I got ( a totally senseless result) After manually trying out a few values , I came to the conclusion that a Shift in the C-axis of -150 was more or less what I am looking for (this value of -150 gets added to every C axis output. With the shiftc of 150 in my post , this is what I saw on the machine :
