Sorry for the delay.  Been a busy day.  I've attached the script and some pictures I took today of using the setter for X and Y.  The script is something I found on the internet and spent a bit of time getting it to work for my particular application.  Have fun!

We build plumbing headers and such for our waste treatment plants from HDPE. We have a Drader injectoweld gun, a hot air welder, a semi-automatic butt fusion welder, a socket fusion welder, a spin welding tool for molded tank fittings.

Now we have figured out a way to spin weld short nipples and flanged fittings using our CNC bed mill!  We mill a flat on the side of a 12 pipe. Then using an arbor to hold the pipe or fitting in the spindle we spin it, rubbing until the material melts and force them together. A perfect weld in about 10 seconds! Alignment and location is perfect too.

of course you could just buy the 2010 screenset and just use the good probing plugin it has.

It glued that block to the base-plate like it had been mechanically-fastened!  Milling the master now!

Great idea! Something to put in the 'memory' Wink bank for the future..

Bob,
I blend my own from a proprietary blend I developed while I was GM of the fireworks factory.  No matter where you get it, it's 'important stuff' for a machine shop.

This is just a "Hey!  Lookie what I did!" thing.

I keep some pre-cast blocks of machinable wax on-hand because infrequently, but fairly regularly, I make 'master molds' for casting silicone molds for making specialty 'dipping compounds' for pyro.

I had a mold to make that was ALL the way out to the boundaries of the pre-cast block, so there was no expedient way to clamp it to the mill.  After some cussin' and thinkin', I went out the the scrap pile, and found the worst-oxidized chunk of 1/2" aluminum plate I had that was just marginally larger than the wax block.

I cleaned-up the bottom of the plate, so it would mount securely to the mill, but left the top rugged, raw, and full of pits and oxidation.  Then I heated it until it was just hot-enough to melt the machinable wax, and just dropped the wax block on the plate.  It melted a bit, maybe using up about 0.060" of the bottom, then cooled.

Since our discussion on rubber stamp making I started melting machining wax into a mold made of aluminum.  I can waste very little wax this way, remelt it in the same mold, and add a little if necessary from chips that blew away the last time.  Since I was going to melt the wax anyway I didn't even buy blocks.  I bought pellets which were slightly cheaper.

When storm Ophelia passed over the other night our power went off eight times over a 24 hour period and that procedure is exactly what we do to make a candle stay upright on an old jam jar lid.
