I have seen your post and can not look at the problem at this time I have an OEM that I am working with and as soon as they are done I hope to get into that section of code to see if we can find the trouble...


Thanks
Brian

I am on the road today and will be back at the end of the day... when I get back I will have a look at CV again.
thanks

Ian,
CV angle is only telling mach3 that it must come to a full stop at the intersection point of the two moves...

Run this as a test
(Machine needs to be at X0 Y0)
G01 X100 F5000000
Y50 X50

IF the CV angle is at 90 you shoudl not get any rounding of the corner... test it with CV on and CV off. What do you see??

thanks
Brian

I will try to test... Could you make the file into 2 line moves and I can use that to test with... I can't have more then that to test with

Thanks

Sherline mode will make the pulse 20us long... There is going to be a rewrite for the manual in the next year. the Manual rewrite will cost about 10,000 minimum! So we are going to let mach3 finish growing and will start back on the manual.

Check this out and I think it should help you

General Mach Discussion / Re: CV setting angle

« on: September 27, 2007, 10:15:08 AM »

I would set the angle to about 90 and see how you like the setting on the machine... they angle that you "like" on your machine is going to have more to do with the feedrate and the Accel that you have set on your machine. If you have an Acceleration of 20 or more and a feedrate of under 100 IPM you will not need the CV angle settings. If you are running an machine that is under powered and has an acceleration of 5 or less and you are trying to make a cut at 200 IPM you will have bad rounding on the corners and I would think 90 deg CV angle should help. The interaction of the feed and Acceleration is why most people have a hard time with the settings and any machine that has a proper steps per unit and good acceleration will not have a problem.

Hope that helps
Brian

Lcam is not  3D cam package... We only were looking at it as an importer for 2D DXF's.

Are you doing this with the P Port or an external device?

Can you just setup slaving under the slaving settings???

You need to take out the screw mapping and see if you can just get it to work... You may need to set your step pulse width to about 5-8 to get good results on your distance tests. Also have you tested Sherline mode?

thanks
