This is not a high priority "must have it" for me.  Just an "it would be nice" thing.

This is one of those little efficiency related things.  Often I can rip a pretty healthy load in climb, but when I come back in conventional the machine screams.  So... I program those types of cuts for climb.  However, mixed would be more efficient… but... the machine screams.  It would be nice to adjust the cut so that it takes say 30% WOC in climb and comes back at 10% WOC in conventional.  You might argue that it might be faster to just climb cut it since it's removing 3x the material per pass, but when you are ripping chips at 95IPM and rapid is only 150IPM its not faster to waste all that travel.

I never have tried that plugin.  I'll have to give it a shot. 

The .stp implementation still isn't ready for most of the wok I do just yet.  Well, unless there is a recent update I have missed.

To be fair I get better cuts using climb from the bottom with the regular thread mill plugin, but the way I suggested might just work for the problem you described, and once you know how it works its really not much harder to use than the thread mill plugin.

I used spiral milling to cut threads in the manner I described without damaging the threads before I used the thread milling plugin.

If you can stand a circular pass at the bottom you can start at the the top using a profile MOP and tangent lead out at the bottom. 

Spiral leadin.  Tangent leadout

There is a registration hack for XP, but XP its not pretty.  Its been years since I ran across it.  You might find it someplace like Pirate Bay, but there is no telling what else you might catch with a visit there.  

Ununused usually means new or new old stock.  While there might be some around its going to be hard to find "that guy."  

That being said, in the early 90s I was that guy.  I bought hundreds of boards for XTs for a dollar a board so I could continue to support the guys who couldn't afford to upgrade to an AT.  I made a few dollars doing it too.  It was nickel dollar stuff, but it was easy money.  Mostly memory upgrades.  Some other things.  MFM-A and RLL boards were popular too.  Gave them more hard drive without buying a bigger hard drive.  I don't know how many 10meg drives I turned into 15 meg drives for guys who were thrilled to get the upgrade.  Used the heck out my parallel (home made) laplink cable back then.  Used to have guys just show up at my house and say all I have is $XX.00.  Can you do anything for me.  Felt like a drug dealer.  Some of my neighbors might have thought I was.  LOL.  Back then I was into motorcycles and there were always two or three or four park in front of my garage. 

I have a bunch of computers locked up that I have not gotten around to data wiping.  Most will be PCI though.  I'll have a look.   I even have a couple old pretty cool multi processor (multi socket) servers.

Id have to look,  but I may have several, but not unused.

Wow!  I just don't remember.  I don't even know where my xbox360 controller is right now. 

Klause wrote a program called Mach Screen which allows you to make and modify Mach Screen sets.  At one time I had a custom set for using a touch screen on my big mill. 

All my current screens have an extra button on the home screen to turn tool path display off.

I can't recall off hand about changing the jog rate, but I thought there was a list of settings available in the settings for the Xbox360 plugin. I might have had a button set so I could either jog or step.  Like I said its been a while and I just don't remember. 


I did have an issue with crashing Z slowly sometimes with the Xbox360 plugin running when I shut down.  I had to get in the habit of always pressing the e-stop before shutting down.

I have not found STL files to be easily editable.  Sometimes I can convert modestly simple ones to solid models in ViaCAD.  If you have Olsen's toolbox you can sometimes convert slightly more complex ones, but 95-99% of the STL files I work with have too many facets and conversions tool just bog down and fail. 


Ultimately I save every project in its native format before exporting the STL to begin with.

NASTY Centroid control soft.

Huh?!  I thought you put a Centroid control on your mill and loved it. 



As to switching an air solenoid valve for "cooling" you still need a low current trigger relay or contactor for it with Mach or your current setup triggered off the spindle on lead.  Just the trigger source would change.  Why not go ahead and slap it on there. 

Now, if you are just using a ball valve and manually turning on the air...

Thanks Eddy, because I use Win 10 Home edition this would not work for me.

But, there is fix for this, it does work! Mach3 is working normal now.

Awesome Bubba.  Thanks for sharing that.

I might suggest that the .stp file is opened in two layers.  One with the mesh surfaces, and one with all the other geometry.  It might make detail work a little easier.  Another thing might be the ability to highlight and select all lines, arcs, etc adjacent to a selected mesh.

Well, what you see is sort of what you get.  In the MOP settings resolution is a possible issue as well.  

Let me back track.  I use ViaCAd primarily for my 3D modeling.  I have Fusion as well, but I am just more accustomed to ViaCAD.  When I export an STL file I get a pop up screen with a bunch of settings.  The only one I ever change is Normal Deviation.  By default it is set at 8.  That creates fairly coarsely faceted STL files.  For 99% of my work when I drop that number to 3 its "good enough," But for some things I'll drop it to 2 or sometimes, but rarely, 1.  The smaller that number the smaller the triangle facets.  

I would note that the the finer the resolution of the STL the larger the file size.  CamBam can be pretty good, but it does have some file size limitations.  Multiple STLs can also cause memory issues.  

Now as to the other matter.  When doing 3D cuts the resolution is what determines how often CamBam checks for proper depth along the tool path.  Its a % factor of tool size.  .05 means a distances equal to 5% of tool diameter.  

~~~~

Just out of curiosity I tried normal deviation just now on a sphere from .1 to 20.0.  I received results from .5 to 16.  Lower resolution than 16 gave the same as 16.  Higher resolution than .5 crashed.

Ha.  An H89A was our second computer.  My dad and I built the KIT.  Our first computer was a Commodore Pet 2001.
