It would seem that "H0 Z0" would cancel the offset and send the machine to Z0. Since there is a Z work offset applied from the gage line to the top of the part ( maybe like Z-15.00), the machine would try to send the gage line to the top of the part resulting in a crash. Thanks for the help, Mike

Hello, I am wondering what the best codes to use to retract the Z axis home on a Fadal using format 2. I can't have anyone try it for me and the customer is 300 miles away. The machine uses "Tool Lengths" like a Horizontal mill and large Z work offsets. They tried G49 Z0 in the past and get a crash. I think this will not work on a fanuc type system either. All I need is a Fadal equivalent of "G91 G28 Z0" or "G53 Z0". One or both of these may work but I am hoping for someone that has seen it work. Thanks in Advance!, Mike

You should not need them. This clip is from the Camaix website: quote: '5AxVirtualMachine' is fully integrated into Mastercam. Every customer who has got the Mastercam VX MR2 and higher and a active maintenance can use the simulation. I don't know what your problem is? Try it on another box or ?

Mike, Open the Toolbar states and turn on the "Multiax Toolpaths" toolbar. Mine showed up there. quote: where did you guys put the codes in,i cant figure that out either. What codes are you talking about? If the software will not run from the chook, I would re-install the latest version. edit: Look in "Add or remove programs" and see if there is one called: Machine Simulation with collision check for Mastercam VX2" Mike

Mike, Did yours show up on the multiaxis toolbar as mine did?

Something is going on with that one. Mine just showed up on the Multiaxis toolbar. Meanwhile, just alt+c and run the machsim chook Mike

MR2 had this issue. It was fixed for X2. Mike

Dave, Sounds good. Thanks for the Info. Mike

Ron, I appreciate the input. So..it sounds like you are having the same issue. I have tried everything and just can't get it. It seems like I am missing something. It is real nice stuff except for this. Thanks!

Hello, I am trying to get a custom tool to work with the Machine sim software. I am using a Lollipop tool. The custom tool displays fine in backplot and verify as always. The issue is that when I try run to Machine sim, it gives me an error. Has anyone been able to do this successfully? Is there a work around I am not seeing in the simulation software? Thanks for the help [ 05-16-2007, 09:06 PM: Message edited by: Michael Whitten ]

I am unsure at this point. I think the question is "do you need it or not". I do not know the complete info on the machine but I do know some machines do not need it as Paul mentioned above. If you program the machine at a certain feedrate, does it appear that it goes that fast? Maybe have a look at the manual. Can the dealer supply sample multiaxis code? Mike

David, There looks like there is a mistake in the second example above where they are getting F1400. It should be F140. In simple form. If the machine travels 5" at 50ipm then it would take 5/50=.10 minute to complete. The inverse is 10 so F10. It is easy to run this test. Just program something like a line and post it. I just did it. The code was programmed to .100" steps at 50ipm. .10"/50 = .002 minutes. The inverse is 500. The output from any of the posts around here was in fact F500. Mike

David, I do not know why the machine is jerky as I have not seen that issue. I found a good explanation of Inverse on the web. It explains it nicely: Link HTH, Mike

I just sent this in to QC. If you keep hitting "Enter", the message with eventually go away depending on the amount of transforms. I am wondering if this will be OK for now? It seems like it would be? Thanks, Mike

David, quote: How does MC come up with an Inverse feed rate of F349.7 for a 500mmmin linear feed rate? The clip I posted above says how. I pulled it from the Haas website. The fanuc book should also have an explaination. MLS, This G43.4 sounds cool. I will check that one out. Thanks, Mike

David, I am not a post guy but until better/other info comes along here goes: quote: Can someone guide me through the settings please? use_fr should it be 2 or 3? inv_fd_type should it be 0 1 2 or 3? inv_sec ? rot_feed ? I would set the "use_fr" to 3 I believe this just means to use Inverse on any type of rotary(5ax code) motion. I have a post that I have used and one that I believe to be good that has it set that way. "inv_fd_type" I always leave this set to 0 only because I don't know any better. There may be special machines/situations that require different though. "inv_sec" I have only used and seen this set to 0 Here is a clip from the Haas website. ------------------------------- Inverse Time Feed Mode (G93) This VMC/HMC feature specifies that all F (feedrate) values are to be interpreted as “strokes per minute.” This is equivalent to saying that the F code value, when DIVIDED INTO 60, is the number of seconds that the motion should take to complete. G93 is generally used in 5-axis work, and sometimes in 4-axis work as well. It’s a way of translating the linear (inches/min) feedrate assigned to the program – F30, say – into a value that takes rotary motion into account. When G93 is activated, the F value will tell you how many times per minute the stroke (tool move) can be repeated, based on the linear F value. Haas has been able to accommodate full 5-axis machining for many years; however, this feature, in conjunction with aftermarket CAM systems and their post-processors, offers even more flexibility and versatility. ----------------------------- "rot_feed" I have only used and seen this set to 0. I believe this just means convert the NCI rapid to rapid feedrate instead of G0 quote: The machine did NOT alarm with G93 and SGI. The problem now is the machine using G93 is very jerky it is not smooth like it was when I was not using Inverese feed? The rotary motion is jerky? Is this with "use_fr" =3 ? quote: In the operation manual. M250 GI,super GI standard mode M251 GI,Super GI quick mode M252 GI,Super GI hidh-precision mode M253 GI,Super GI special mode M254 GI,Super GI M254 mode M255 GI,Super GI M255 mode Anyone know anything about these M codes? The Makinos I dealt with were a bit older. 1994-1998 models so that is what the following info regards. Makino just assigns different parameter sets in the control for the acceleration and deceleration type settings. Back then, all the machines we saw had very conservative settings that would drive a guy nuts unless you were not in a hurry. We had the Makino enginneers work up some special settings to induce a specific inaccuracy for each M code. IOW, we had standard mode, quick mode and "supersonic". We actually had them loosen up the settings so much so as to allow a .004in inaccuracy for the rough mode(supersonic. This would allow 1000ipm feedrates in 2d and 300-500 in 3d without slowing down. As I remember you just code like this: M251 G05 P10000 There is probably more advanced High Speed stuff nowadays but I am not to up on it. HTH, Mike

quote: I think you may find that Inverse time Feed is also an option for your machine you may need to contact Mr Makino This has happened to me. It is very unfortunate that the dealer will sell a multiaxis machine and not suggest to the customer that they should purchase the option. For that matter, what would one do without it? Mike

It is hard to say what caused the alarm. I have never tried any multiaxis milling without inverse feed. I think if you turn inverse feed on and maybe play with SGI a little, you should be good to go. Mike

David, As I remember, Makino had a seperate M-code modifier for multi-axis code when using SGI. Maybe is was M254 or something like that. You may need the actual SGI booklet to find this info though. Mike

Got it Thanks

Mine is happening in X2MR1 so I guess I am going back to X2 for this job. So this is also happening in X2 also? I have not tried X2 base release only the sp1 version. Thanks, Mike

Hello, I am having a problem when I try to backplot a “Toolpath Transform > Rotate Toolplane” a 5-axis toolpath that was done in the Advanced Multiaxis. When I select the Transform op and then hit backplot, the system reports an error that says “5AXMSURF” in the upper blue area and “Cut tolerance must be greater 0” in the lower area. If I delete the transform op and regen the Multiaxis msurf op all is well again. This is very weird. Has anyone been able to rotate one of these toolpaths in X2MR1? It did this on two different machines. It works fine in X2 Thanks in advance!, Mike [ 05-04-2007, 09:32 PM: Message edited by: Michael Whitten ]

gcode, I did get the email. Thanks! I was able to get around the issue with the info we got from CNC as I listed above. I will have to study all of this when I get a little time. I will let you know. Thanks, Mike

mpmcnc, You usually create a z2g and send it to [email protected] Mike

Thanks Jon! Mike
