We're always very much interested in diagnosing and resolving any potential post issues.  Just need you to forward your Zip2Go via your reseller.

We still might, but I gotta convince management to pay for it. In the mean time MC has so many different ways to attack a problem, that I can always find an alternate solution. laser.gif

I don't want to speak for Dave but Postability doesn't typically charge for fixes.....mods, yes, fixes, not in my experience.

You can do a smooth toolpath with triangular mesh from Moduleworks (with 3 axis tool axis control) if you have a multiaxis seat.

This toolpath is not well known because it's usually used with rotary axis but it can be very useful with a 3-axis machine too.

However, your post may need customization as it will output gcode$=11 in NCI file.

 

Here is an example.

TriangularMesh.mcam

Apologies Mastercam for resurrecting an old topic.

It seems that all of the moduleworks Triangular Mesh toolpaths are treated as 5-axis. None of the 4/5x posts would output axis M-lock codes.

Let the cuttype be controlled by the tool axis control, post problem solved!

Why waterline or surface finish contour does not have spiral cutting method. Most of the surface roughing toolpaths almost always leave more stock than specified anyways: not a problem for aluminum, yet a huge problem for Inconel.  Am I missing something here?

Need to talk your post builder and have that logic added if that is a problem. Have you tried seeing if the post has an Axis Combination for  3 Axis, 4 Axis or 5 Axis. maybe that might be the way to get the post to not output the 5 Axis clamp unclamps not needed for your machine when you don't want them. Some post have a switch to not put them as well.

It's an old proven Mam72-35 post done by the House. Everything works great expect for Triangual Mesh toolpath's: I modified the post to force the Lock through the misc op variable but I don't like it. It's clearly not a post issues.

That makes me think it is post related since depending on how old the post is it may not have the logic built to support that toolpath in 3 Axis correctly.

Mr. Bouman do you mind testing any of yours in-house  posts  through Triangular Mesh toolpath?

Try it.

port.mcam

Not at all how I would run a port, flowline wouldn't be my first choice (or a choice at all for a port) but since I perceived this as a challenge here ya go.

It has 2 retracts but also has that nice morph lead in/out so if I were inclined to use flowline on a port I would let this run.

I think the best process is to email your dealer who can get a hold of their post department. 

Imho, It's an issue of how Mastercam handles Moduleworks Triangular mesh toolpath's .  The post is fine.

Thank you for your effort.

Perhaps this port was a bad example. I mostly use this toolpath for roughing purposes. The problem becomes more apparent when you try to rough an odd shape from the outside.
