99.9% of my time is setting in front of my computer wondering why BobCad does crazy things. It's no wonder why i don't have time to build cues..haha. OK here's the problem although all the setting is right in BobCad the pictures will show what happened, and it will not cut pockets or parts right, i have come to the conclusion it is in the post processor, although i am using the same one for a few years and now it doesn't work what happened? now using v26 but same thing happens in 25 or 24! Is anyone using BobCad Mach3 with unique cnc that could try my post processor to see if that is my problem, or would some one have what ever post processor i could try, this is all i get done trying to figure out problems with this software.!! The tool path looks good, and in the simulator looks good but on the cnc not so good. What other program are you guys using? don't turn enough profit to justify mastercam, any suggestions appreciated. No square corners and rounded the island also. Take that back 1 square corner, wounder why?

Thanks for looking

I have no ides Tony, what ever Unique sells.

That could very well be the issue. Even if I want to engrave my name that controller does not understand some letters, makes no sense. I will be doing an upgrade for around 500 bucks for gecko controller box. If you have the round connections on the back of the controller you have a xilotec.
 
It very will may be the controller, it is that black box with one switch in the upper left hand corner. i think they have a newer style now, but not sure, i talked to Jim a couple days about the problem.
 
That is it. You can get a kit off of flea bay for $500 with motors and I guarantee you will never look back. Jim might chime on here about it.
 
I may have to do that, we'll see. Haven't had any trouble until now.
 
I really don't need to draw anything i have 100 probably more inlays, i just generate tool paths.
 
For some xilotec does not translate well bobcad toolpath... The post processor is very old.
 
Check your email and let me know how well the gcode works.

Jim.

I do agree that the G540 box from Deepgroove is a great way to go. It's a much better controller than the Xylotex.

But, I've never had any code that could be run on the Gecko that could not be run on the Xylotex. At the controller level, it's all about G code and BobCad can certainly output whatever G code the Xylotex needs.

Just to make sure everything is clear as mud, the Post Processor is a function of BobCad, and not the controller. All Cad/Cam software's use this "Map" for lack of a better term to know what kind of machine they are outputting code for. Of course, there's the basic stuff like what Axis are used and does it turn the spindle on and off, but there's other things too like how it deals with sub-routines, tool changes, and whether or not it uses cutter compensation.

Post Processor's can be highly modified to do some very specific things.

The Xylotex control is pretty weak compared to the Gecko, which is the biggest difference. The only other difference that really matters to me is that the Gecko is much tougher and less likely to damage if a wire breaks or a plug comes loose. I've converted pretty much all my machines that were originally built with the Xylotex over to the Gecko. Most are the G540, but my bigger machines use the G203V discreet drives. They even more robust and powerful than the G540's, but because they are all separate parts they are much more difficult to put together.

Man no offense, but that's some ugly tool paths.
Have you checked your default part and cutting conditions.
Also what machining strategy are you using/tool sizes and offsets.
Are you using system offsets or tool offsets.

I've never seen Bobcad do something different from simulation to machine.
Maybe I've been lucky.

Hopefully you will let us know how things turn out. Always looking
for gotcha's to avoid.
 
Yeah Steven, I hear ya. i am thinking it is in the controller, i have BobCad 23-26 and they all make rounded corners. with the same post processor. but maybe the post processor is damaged. Mc2 is helping me with the problem, it is frustrating when you THINK you do everything right and it still comes out wrong. ha Tool path in the picture looks great, but it doesn't come out that way.

I agree, that looks like hell. Maybe not the post....maybe just crappy parameters in machine settings.

Curious, are you selecting "mill 2 axis" or "mill 3 axis" in the tree?
