General Mach Discussion / Re: G Code Question

« on: September 20, 2018, 03:49:29 PM »

That worked.  Just that simple as deleting a bad line of code.

My question is why is it there and can I modify my post to stop it?

oh and I also found out the hard way that the same line of bad g code is also at the end of the program.

Thanks and if anyone knows how to modify a post I'm open for input.

General Mach Discussion / HSMWorks and Mach3

« on: September 20, 2018, 09:33:14 AM »

Hey Y'all  I've run into a funny and don't know which door to open.

When I run a job that has been posted to Mach3 from BobCam everything works fine
When I run the same job posted to Mach3 from HSMWorks, It doesn't work. ( it starts by trying to move the z past zero and bury the router bit into the router table.

I'm using the most current Mach3 post file from Autodesk Website.

These are the first few lines of my job that was posted from HSMWorks.  Line 4(G28 G91 Z0.) is where the z starts misbehaving and goes into the negative values.


(T6  D=0.25 CR=0. - ZMIN=-0.53 - FLAT END MILL)
G90 G94 G91.1 G40 G49 G17
G20
G28 G91 Z0.
G90

(2D CONTOUR2)
M5
M9
T6 M6
S17000 M3...

ANY THOUGHTS OR HELP?  I'd much appreciate it.

What thread would be correct one to ask a question about running a job that has been posted from BobCam that works fine and the same job posted from HSMWorks that doesn't work?

Hello everyone,  my name is Jeff.  I work in the movie industry as a special effects person who makes specialty props.  Several years ago I purchased a cnc plasma kit that runs with Mach3 and after catching the cnc bug and wanting more I purchased a 4 x 8 router kit from cncrouterparts.com and have been teaching myself the art of cnc routing.  It too runs with Mach3.   I use solidworks for my 3d work and use tool path plugins from HSMWorks and BobCam.  Most everything I do is either wood or Urethane foam.

General Mach Discussion / Re: Proma THC works in test mode only

« on: May 18, 2013, 02:23:21 PM »

Well I figured out for myself that I can't use the information from Viperplasma completely.  The wiring diagram I downloaded for the THC from their site was wrong for my powermax 45.  I went to the found and downloaded an operator manual for the THC and it indicated the wiring to be different.  The THC has a low voltage sense input because the hypertherm Powermax has a 1:50 voltage divider built in and the factory outputs from the plasma cutter had to be hooked up to the appropriate low voltage inputs on the THC.
After all that the THC is working sort of.  I have nested 10 parts in my sheet cam and when I cut in Mach 3 the cut heights are very inconsistent.  When I'm cutting .125" aluminum sometimes it cuts at .200" some times at .250"  sometimes up to .395".  What's going on?  how am I supposed to set my initial Z height?  do I set Z at zero with the torch touching the material?  My friend said his torch lowers and taps the material when he starts a cut program.

 ???Hey Guys.  I have the same problem I think.  I am new.  My Proma THC (bought from deadbeats ViperPlasma) works in test mode only.  Another thing I don't know is where to set the Z.  Do i set it so the torch head is touching the material? or to what looks like a proper gap between my torch and material?   Is the torch supposed to lower itself and find the material surface height automatically?   Back to the THC, the display is only dashes when I run a cut.  I've set the HV to 300 like you suggested with no results.  I got my voltage from the Hypertherm manual of 118 for .135" aluminum, does this sound right?  The H45 is 4v, the DT is .5v, the HV is 300v.
