My control is locking up when trying to tool path this profile. I am attaching the x_t., tol., and twd file. I've tried a few different tool setups even a single rough pass and still can't get it to tool path. Someone with a newer controller and computer may have more success. Thanks, Forrest

Sorry disregard that last file it was from beta and you probably can't open it. Here is the new one. My twd is on a piece of 4" mdf material cut 3.22" wide with a slight radius. I've tried changing from board stock to panel stock to a cabinet back of the same stuff with no success. I haven't tried to make a straight piece but will later today. I did find a slight undercut on the profile early on but removed it and still cannot get it to toolpath in PM. Forrest

My problems with the PM always leads back to the basic dxf file that I am trying to get to profile
If I draw these profiles my self, no problem. But when I use customer supplied files, I almost always have problems
Start from scratch and redraw the profile and look at the resulting file sizes all the way through the process.
Starting with dxf then tol then twd
small changes in dxf file size make huge changes in twd file size
I have wrestled this beast many times and am sure of only one thing. It will be back the next time i get a file from someone else
If you want to send me the dxf file I will look at it also dxf part outline and thickness will@willmade.com

I guess I'm not sure what you mean by inside turn but I have many times machined square inside corners such as shown. I will have a chance a little later to redraw in cad the profile and try to figure out whats going on. One reason I wanted someone with a newer setup was to see how long it took to generate the toolpath. Forrest

Forrest,

We just upgraded to the Q Core Control and your file froze it also.

Forrest,

Seems like it is the arc in the attached picture that is causing the grief.

I recreated it and now all seems to work. I have attached the modified .x_t file and the .tol file for you to review or use. Please try it on your exact part with the curve and let me know if it works with it.

Not sure what the real issue is with it, so I am going to submit this to the programmers and let them see if they can come up with anything.

Thanks, Scott. I was able to slightly mod the file as well and get it to run. I was also able to update my OS as per our discussion and PM as well. I do have another problem with it that maybe someone can shed light on. The material stock is 4" thick and the profile is only 3.52" tall. I set the tool to plunge -4" and all is well until I get to the cutting. The 3/4" hogging tool has a 5/8" by 5/8" stepover and down but will not start on the edge of the part. It starts on the first inside wall at the top of the profile. My piece is already to size so it leaves a narrow strip at the top that the 1/2" ballnose wants to blow out. I can't seem to figure out how to make it machine all the way across the top of the part. Forrest
