Smooth profile ramp glitch

[epalmerANXTH]

For awhile now we have been using 2D contour to mill an obround hole using ramping.  However it seems that it is no longer working.  There seems to be glitch when milling obrounds that are close in size to the tool diameter.  The obround I am cutting is .2654 diameter with the center to center of .145 inch.  I typically use a .250 endmill for this process but it will not post any longer unless I select keep tool down and pick a pre drill point.  And even then it is no longer ramping.  I can however get ramping to work if I select multiple depths, however the top height is completely bonkers.  It is starting the ramp half way into the material even though I have selected the stock top as the top height .  I tried milling random diameter obrounds using different tools in my library and saw the same issue when milling close to diameter obrounds.

If you upload some examples, people will be able to help you with this.

There is a current bug that prevents the use of tools that are close to the size of the feature you are cutting (with 2D Contour). The current workaround is to define an Entry point.

If that doesn't work, could you share some examples?

Hi @epalmerANXTH Thanks for feedback. It sounds like a bug which has been introduced and fixed recently. Please wait until next version is avalable and try it again.

Workaround: Specify "Entry point" for Contour2D with empty toolpath. I hope it'll help.

Sorry. @seth.madore was faster.

Thanks for confirming.  The entry point fix seems to work for now.
