Thanks again Ian.   I got the screen designer, made that change and it is much better.  Really appreciate the assistance.    Next up is a floating head.   And recommendations?  --Doug

Got it working!  Thanks for the assistance.  Here's the video:  http://youtu.be/kf8S3rL3wYw

I'm wondering now if there is a better way to do this, as there is no apparent way to get it to go below 0 on the Z.   I guess I could tell the CAM program that my material is a half inch thick and then set Z:0 below the material on my table?  What's the normal work around?

Thank you very much.  Your assumptions are correct. Here is a video of a test:  http://youtu.be/cXc5-VPiej4   I didn't ever see the Max/Min THC move settings because I'm using the Mill profile as I have done for years.  I'll switch to the Plasma profile and try it again.

General Mach Discussion / Proma THC - Moves Z up but not down.

« on: November 02, 2012, 09:52:56 PM »

Just got around to wiring in my Proma Compact THC and it works in test mode, moving the Z axis up and down.  But when it's running g-code it will move up when the THC signals up, but it will never moves back down when the THC is signaling down.  The diagnostic page indicates that it sees the down pin high, but no movement.   I'm running licensed Mach3 with a Sound Logic PC-2-route M-2 breakout board.  And I have switched the up and down pins and still it move up, but not down.  I'd sure appreciate any help.  It' great having it just do half the job, it will be sweet when it does the whole job.

Greetings and thanks for all the helpful post.  The Mach3 videos have been fantastic for figuring this stuff out.

We got a used 5 x 10 router table and got it working now.  We added on a vacuum table that will double as a water table so we can plasma cut parts for the steel sailboat we are getting ready to build.  The router will do interior foam relief work and foam parts for lost foam casting.  We still have lots to learn about CNC but it's capabilities are wonderful. We are just completing an submarine/jet boat it sure would have been nice to have 4 years ago. Live and learn.

Come see our progress at: http://www.submarineboat.com/plasma_router_cnc.htm

Thanks Again
