Thank you!

Jean

I'm considering the addition of a Multicam 1000 series router to my shop. Does anyone out there happen to be running one along with MadCAM? I see there are two post processor files out there but I...

Hah. I decided to make a quick sample file so that I could upload it and then it worked me. I went back to the customer file ... and it also worked. Sorry for the trouble, you can close this one!

So far all of my MADCAM work has been surface milling. I have a project now that would best be done with curve milling along curves. I believe I have generated good toolpaths for these curves...

Ahhh cool. I tried raising the box top but not by the exact radius of the tool. This worked for me too!

Thanks for the workaround, it will allow me to finish the rest of these a bit faster...

I'm on the latest 5.0 build and have encountered a planar finishing problem. When using .375" ball or smaller the toolpath generates correctly. When using a .5" or larger ball mill it skips a...

Dan,

I really appreciate your help with this. Getting the post processor fixed for me was a great help. Joakim should replace the current one with this.

Should I send an email directly to...

Yes, I am posting code and seeing the values above 3.125"

Yeah, it always bugs me that Ball nose cutters always show the lines above the actual cut depth. Is there a way to change this?

I...

Update2: Actually, it does happen with flat end mills as well. What type of tool path you are generating is a factor. Roughing leads to the worst case of traverse heights going higher than they...

Update: I've been experimenting and realized that the problem does not happen with FLAT end mills. Ball mills are where the problem occurs. Not sure about the other types of mills. This is...

Dan,

The design in the file I'm working on does not belong to me. I've created a very simple example with the same diameter of final product along with a stock model of the same diameter as what...

It lowered the highest traverse from .7992" to .6417" - still too high for my machine. I really need it to not move more than .125" above the surface. To get the .6417" to work for me I would need...

Dan,

Thank you! This does generate values for W! I'm going to put your post file next to the original to see exactly what you did. I owe you!

This leads me to the next obstacle which is more...

I don't know if this will help, but these are the lines I had to add to my Wincnc.ini file:

[W Axis]
axisspec=p0 s3 d7 r500 a400 k3
axisvel=r300 f300 s50 m200 h300.

Yeah, MadCAM 5.0

I'm not sure on the syntax for spindle speed. Unfortunately Shop Sabre is closed today. I do not use coolant. Here's the beginning and end of some 3-axis code:

G80 G90
M3...

Dan,

I did notice the error in the line starting with G1. What I posted is the default 4axis file that comes with Madcam. Here's the post-processor with the error fixed that I have been trying...

I just added a 4th Axis to my Shop Sabre CNC machine. I need some help getting MadCAM/post processor setup up correctly. I was able to get MadCam set up so that it would generate what looks like a...

This may be more of a general Rhino question but I figured I'd try here first...

For some reason MadCAM shows up on my menu bar twice. Everything seems to work fine but I'd like to fix it if I...

Thank you guys for your information. I can see now that running the planar finishing step twice is the proper procedure for cutting harder materials. I may even start that for MDF as I sometimes...

wdaehn: Yeah, sometimes I do play with my box size so that it is sure to get the top surface as I want it to. However, lower surfaces will still get left with more material than I would like...

Fairly often when creating a roughing tool path, it will not remove the top layer of material if it is thinner than the "stepdown" depth even though it is thicker than the "stock to leave" setting. ...

I just tried your file. For some reason, even the first move which should be at rapid rate is being set to the cut speed rate. Here's an example generated using your post processor:

G80 G90
M3...

Just wanted to post a quick update for anyone who happens to use a WinCNC based machine and comes across this issue...

By default, WinCNC does not tie the feedrate of the X and Y to the Z. These...

@Dan: After posting, I saw your second post with the revised attachment. I'll give this a shot.

I do not use coolant, these are being cut out of wood.

Thanks again.

Jean

@Dan: I believe what is happening is that - yes, my machine does support modal g code BUT it is only on a per axis basis. So you must change the feed rate for each axis independently. Setting the Z...

@turmite: Done! Thank you.

@turmite: I am using 4.3 - I did not realize there was a beta available for 5. I will grab that to see if my problem goes away.

@Dan: Attached!

The finishing passes sometimes pass through areas which are not supposed to be cut. This seems to happen only when I use Regions. Here's a screenshot of the simulator which clearly shows the...

I am running the latest version of MadCam but have run into a feedrate issue that is causing me problems.

The feedrates for cutting are not always being set properly after a rapid travel. I am...

I'm carving a 3D mold but the area in question is a 24" x 5" area that is perfectly flat. So the bit moves 24" across the X axis then steps over on the Y Axis as per my tooling settings and then...
