Id send the post to CNC

Hi Lee, I just emailed you, My suggestion is to try using R value radius output for arc motion as well if it is at all possible. As i understand the problem (arc is taking the opposite arc motion, as if using a signed -R value), it seems to me that the IJK values may not be right therefor the machine cant interpolate/calculate that motion therefor it is moving in the opposite direction with a much larger sweep angle to try and get to the end position of the arc. Let me know if this works for you.

for future reference.... start, all programs, mastercam x, documentation V9-vX function map if you know version 8-9 etc. this is a very helpful document

I have people asking me all the time if i know anyone who is a machinist or programmer. Companies are screaming for these people up here in edmonton. The amount of jobs FAR outnumbers the amount of available workers to fill the positions. Up here the workers have the power. Its incredible actually, If you cant find a job here, you must not want to be working. lol

Gibbs has terrible posts from what ive seen, and mastercam multiaxis is far superior. Mastercam documentation and help functions are also much better than what gibbs has to offer. Remachining in corners after roughing is like pulling teeth in gibbs, where in mastercam it is much simpler, plus it also calculates remaining material and shows a visual representation of what is left in the corners to remove. gibbs requires the use of reference markers along the toolpath to set an entry and exit point and manipulating the markers is kinda tough because they never snap to the toolpath in the right place. takes a lot of gtetting used to. i could go on and on lol edit: ps, i was also a fairly gibbs oriented guy as well until i got into MCX and now i also sell mastercam nuff said.

haha I bet theres people on here who could Gcode/macro b program by hand faster and better than bobcad. let alone what mastercam could do....

haha yeah i didnt see the date lol, i was busy workin on somethin else, then i hauled up one i got with the search and posted it before i even looked at the date. lol oops ah well thats what happens when you have too many windows open at a time lol

check your mastercam config settings, configuration, toolpaths (this may not be it since you mentioned solids) and check your memory buffering. mine is set to 512 mb, but if i lower it, Mastercam instantly crashes. so try increasing the memory buffering. im not sure if this will solve your problem tho but you can try it out. let me know if it works for you

edit oops i just saw my comment was already mentioned

oops just saw that youve overcome the problem

ramp plunge zig angle to 0, zag angle to 2-3 degrees

ah i see, ok. well im not sure of the software used to create pdfs, but i know you can find some if you google the topic, but as i recall the ones i looked into would paste a "TRIAL COPY" or something message across all pages until you paid for the software. but you can definetly get it from there.

i dont know if this is what you mean, but you can save bmp and jpeg and whatnot, i dont know about the pdf thing but you can just press printscreen button or ALT+Prntscrn and then paste it into paint or something like that and save it. im not sure about pdf format thought, im sure you can just paste it into whichever program you use to create your documentation. or just use mastercam's - screen, copy screen image to clipboard function

some controls can rotate the program right on the control. I know some (i dont know if all) Yasnacs can do this. The ones i used had a set up of using variables for vork offsets such as this... G54 J#XXX. Then in your work offset page there is your G54 1-27 (27 pages of G54-G59, each with its X Y Z offset) but then it also has an R value, which is the rotation angle of the part orientation, so you can set it up and rotate the program if you wish and the control would compensate for the programmed values. just my 2 cents, i dont know if the post will do it for you tho

the original post unless it was originally set up for a subspindle probably will not be able to post for a subspindle properly. contact your mastercam dealer to find out more information
