Thanks for all the work Forhire and thanks Jim for your input as well,
The biggest problem I have found with this machine is the lack of being able find exactly how certain codes should be used. For instance, I can't replicate the G8/G9 issue on my TC-1 and there is very little mention of it's use in the manual. In my case it's as if G9 is the default power on setting. Any time I've tried a G8, it hasn't been with good results (very jerky movement).
What version is your DX32 software Jim? I have both 6.89.57 and 6.89.60...but can't really notice a difference between them.
As far as G12/G13, when I first got the machine I attempted to run standard Fanuc style G2/G3 helix's. I thought all was good as well, but at the bottom of the helix, when the cutter would transition from XYZ to XY moves, the head would just drop about .01-.015". Not healthy on cutters or parts.
I remember asking Bart at EMI about this and he said there was a software glitch that was never fixed and using G12/G13 was what I needed to do.
At that time, I finally gave up on the helical entry and just predrilled a hole (just needed to get the jobs out, no time for experiementing at that point).
With Bobcad, there was no way to post seperate code for helical....possibly with scripting, but do not know how to do that. A few months ago I gave it another shot but decided why not just have Bobcad output G12/G13 for everything (no G2/G3 at all)....it worked! So my bobcad post outputs G12 and G13 for standard XY arcs with no issue using absolute arc centers.
I will give your latest post revision a test as quick as a I can. For some reason, I'm not getting e-mailed when there are updates to this thread and didn't realize how many responses there had been since my last visit.
Thanks again!
