I did update but it didn't like the expression I was using in the X3 post, i got a host of errors in the post log, but thanks anyway. However I think I've sorted the problem but can't test until I'm back in tomorrow. Thanks all again

Sorry it's me again!! I haven't had alot of time today to mess with the settings as end of month means get everything out the door. but I did the change that Ron suggested and below is a sample program. It didn't output G55,56 etc as requested but it also didn't output G54 on the first line of code. And when it rotated intead of a G0 I'm getting G1,G2 - G7 where the G55, 56 would of been. Hope that makes sense Any help would be appreciated G0 (G0) X-103.635 Y4.932 A0. (G54 wanted here) G43 H2 Z75. Z52. G1 Z50. F750. X37.86 F3500. Y-4.932 X-103.635 Z52. F2000. G0 Z75.

Thanks all I did want G54 only as the machine that the post is for won't accept any other wcs as it stands. You have to pay extra to get all extra bits added on, bit of a rip off really. So Ron's mod I think will do the trick, I will test it out today. Thanks again

Thanks Ron I'll try that in the morning

Hi all My boss has finally taken the plunge and we now have X4mu1 running on one of our computers (the other 1 stiil running X3mu1). After setting it all up I updated the posts and all but 1 are ok with no error messsages after a bit of tweeking here and there. The 1 I'm having trouble with is a modified Generic Fanuc 4X mill. I want it to post out G54 at the beginning only and when I change to mill say the front to rotate the part which it does but not add a new wcs(G55). As I learnt from this forum if I put a 0 in my wcs manager it does what I require, but it would be better if it was fixed by a setting in the post. In X3I had the following in the post which fixed it but in X4 creates quite a few log errors; g_wcs = workof$ + 54 =====>g_wcs = 0 + 54 So I guess there must be something I could do in this section of the post to fix this. pwcs #G54+ coordinate setting at toolchange if mi1$ > one, [ sav_frc_wcs = force_wcs if sub_level$ > 0, force_wcs = zero if workofs$ <> prv_workofs$ | (force_wcs & toolchng), [ if workofs$ < 6, [ g_wcs = workofs$ + 54 *g_wcs ] else, [ p_wcs = workofs$ - five "G54.1", *p_wcs ] ] force_wcs = sav_frc_wcs !workofs$ ] I've searched the forum and there are a quite a few threads on this with most answers pointing towards mi9 which is not present in our post. Is ths something I could add to fix or is there a easier solution Thanks for your help in advance

I had the sme issues plus a few more with the same card when I got myself a new PC couple of months ago, I went back to an earlier driver (175.51) and it fixed all the problems. It might help

I think there is a couple at this site "www.3dcontentcentral.com" not sure what they are like, available in all formats.

Sorry wrong thread, it is late here

I think there is a couple at this site "www.3dcontentcentral.com" not sure what they are like, available in all formats. cheers

Yes Jay I think so. I've done a lot of searches and investigation into the 4th axis outputs. I put the job in iso view and rotate the a xis i80 for real bottom and -90 for new back. I set the wcs to top and t/plane and c/plane to whatever one I'm trying to machine. like I said the weird thing is when I post seperately it outputs the correct Avalue its just when I try and do both ops at once.

Hi Can someone help me with this what has now become a headache. I cut a model of a head on my 4th axis, and when I roughed out the job from the front and back all was ok if I posted the rough pockets seperately ( post outputed A90 and A-90) but if I posted together I got a G55 command instead of the A-90. I've been trying to figure out why and done a test piece which was an eight sided shape and drilling a hole in each face. When I posted all 8 ops I got the right code A-45,A-180 etc but when I posted just the front and back I got the same g55 code. Any ideas what and why it's doing this. cheers Jim

Thanks John I've been looking at the 2 posts side by side for about 2 days to try and get the 4th axis to do what I want it to do as the mpmaster seems to output the correct codes. I guess I'll get there in the end Cheers

Hello all I'm testing out my new 4th axis and i am trying to cut a square thread along a diameter. I've got the toolpath looking right but when I post it instead of only moving in X and rotating on A the output is all X,Y and Z movements and no A movements at all. However when I post it with the mpmaster post it seems to generate the right code, so I guess the toolpath is correct, just my post that isn't. I've checked the CD's on both and they are set up the same If I do a 4th axis rotary cut with this post the output looks right but on this it doesn't. Any help would be appreciated. Thanks in advance Jim

Right Chaps I changed 1 of the settings in the post from inverse speeds to programmed speeds and it seems to be outputting what I reguire. Thanks for all your help

Thanks John I have tried what Terry suggested but like you said I am getting an output of crazy numbers. All I'm trying to achieve is to machine 6 weird shape pockets around a headlight diameter, so I machine 1 then it rotates around then does the 2nd etc. it just seems to be outputting crazy numbers when its doing normal 3d work.
