Who is running this?

If not - what do you run for DXF to G-code?

If so - what do you think about it?

Anyone know if there are improvements on the horizon?

I haven't used it, but it's been in a consyant state of development since it's initial beta release a month or two ago. Based on what I've seen of Mach's development, I'd expect a steady flow of added features as soon as all the basics are working properly. If you're having issues, do realize that it's only been out a month or 2

Hi,

I just upgraded to Mach 3 ver. 1.90.037 and noticed that there isn't any DXF support.

I guess I'm forced to buy MeshCam (or something similar) or stop using Rhino as my design software, right?

I don't use Mach but what does it import besides dxf. Surprises me it will not import that format but if your using rhino it saves to a few different formats try one of those.

Just checked Mach Site and .......

Allows direct import of DXF BMP JPG and HPGL. MACH3

Mach3's .dxf import is now a seperate app called LazyCAM, included with the latest download. It gives much more control than the old importer. It may be a bit buggy as it's brand new, though.

DXFs are no problem with Mach.

As GER said - Lazy Cam is relatively new and it does not work perfectly but it does work and for the price you can't beat it.

I did not start this thread to bash Lazy Cam. This thread was started as a general discussion about this software. I was surprised to see that a thread did not exist already. I am satisfied with it although I am looking forward to the inevitable improvements.

Some of the current issues I have noticed are:

Creating cutting order is difficult. The code is there but it's not in the correct order based on the original drawing’s layer information or on the sequence identified in LazyCam. Manual editing of the code is required to get the desired order and in many cases, the start points must be manipulated to create an efficient tool path – it’s a back and forth with lots and lots of editing but it beats coding it manually (most of the time).

It would be nice to see options for general cutting sequence – such as cut from inside to outside, left to right or top to bottom. Or maybe a “select cutting order” option which would be based the order in which you manually select the entities.

Some entities in a DXF are sometimes completely ignored - this seems to be relatively random but may be related to the integrity of the creation of the polyline but this has happened to me on more than one occasion. For example - the first segment of an open polyline might be ignored while the rest of the polyline is cut. There is always a goofy move associated with the failure – like a G1 move that would otherwise be a G0. I am attempting to find a trend with this error to be of help to the developers. I have been generating drawings for machining for quite a long time and I know that the data has to be clean - no gaps, overlapping lines, etc. and I know this error is not because of bad data.

The DXF data does not appear on the screen when first loaded into LazyCam - you have to turn the layers on in order to see any of the geometry. It seems that they would default 'on' and they would use definable default speeds and feeds.

I am looking forward to future releases and will continue to carry the flag for Art and his crew.

You might want to look at the new support forum at www.machsupport.com
You can post problem .dxf's so that Art and Brian can fix any problems you might have.
