You should call your dealer. I'm sure they can help you. You're right near their office. Mike Mattera

You can put the End Selection under your right mouse button. So then you right click and pick End Selection. Mike Mattera

"a problem!!!" Now there's a descriptive subject. I think Hardmill's got it. Use Project. Mike Mattera

I put together a Post CD that includes my tutorial as a basic introduction to writing posts. if anyone is interested send me an email. Mike Mattera

Too easy to click the wrong one. I Like the "Pick it" then hit Delete function. See wgahat your doing before you confirm. Mike Mattera

Do you have a Lead Out distance = to the cutter rad.? Use a Line/Arc combo for the lead out to make sure it's clear of the part. Mike Mattera

Did they actually update their old postprocessor? Mike Mattera

Delete the Group and select the original selected items. Mike Mattera

Sounds like a simple Swept toolpath to me. Look under the Toolpath - Wireframe (I think). All you need ia s guide curve and a drive curve. Mike Mattera

You might be able to do this in the ptlchg0 section. This is for null tool changes. In english that means "what to do between operations when your using the same tool again". So you contour the outside and the cut a pocket. In between the post looks at ptlchg0 to see hoe to handel the "In-Between Cuts" part of the program. In there you can create a counter for the tool and add to it. tnum = (tnum * 10 ) + 1. So you should probably set tnum = to t just after the toolchange (in ptlchg) to tnum = t. Mike Mattera

Why did you make the chaining tolerance .002" ? Di you have geometry that did not connect? Mike Mattera

Look in the chaining options for a "Chaining Tolerance". Set it to the largest gap you think you might encounter. Defauls is .0001 (I think). Mike Mattera

I should point opcode 3 is drilling. If opcode is not 3 it's milling something. Mike Mattera

This is a simple "is it on or off" test/ pshowcomp # if cc <> 0, " CUTTER COMP = ON " if cc = 0 & opcode <> 3 , " CUTTER COMP = OFF" Mike Mattera

Depends partly on how you projtram. I had one guy who put his feedrate in as .004 . He wanted in IPR output. In Mastercam is was an incrediably slow feedrate. Your not doing anything like that are you? For your Tap maybe? Mike Mattera

John: Nice and compact. Heavy Metal: Some of that is explained in this tutorial. Click on "How To Edit A Post" http://www.mmattera.com/mastercam/index.htm Mike Mattera

I have heard of people creating a post that outputs APT format. But I've never seen one. Mike Mattera

Your post may not have a pwrtt post section so you may have to create it. Basically pwrtt looks thru the post first to gather information for lists at the start of the file. I use this in my posts fo create a tool list at the start. This loops around and counts the tools ans numbers the operations. It then creates a list with the tools they use. pwrtt # Tool table at start of file tnote = t toffnote = tloffno tlngnote = tlngno opcnt = tcnt + 1 # operation counter = tool counter +1 if t >= 0, [ "(", "OP", 35, *opcnt , " IS ", *tnote, " -",*tldia, " - ", "OPERATION IS ", *sopcode,")", e "( ", *toffnote, " -",*tlngnote, ")", e "( ", "TOOL TYPE = ", pstrtool, ")", e tcnt = tcnt + 1 ]

Smaller the tool the more it will flex. 1/8" has got to be all over the place. Even in plastic. if you have to use the 1.8 for some reason, do a cross cut. one pass at 0° and another at 45°. Most lilelt still wont be flat, but better. Check the head/table alignment (tram). Mike Mattera

You can try these training CD's. Many people on the forum have had good luck with them. Click the link below. Mike Mattera

If you want to learn some of the basics, you can start here. Go to this link and then pick the "Stuff For Mastercam V8 & V9 Utilities and Tutorials". There's a starter lesson about writing posts. http://www.mmattera.com/html/mastercam_stuff.html Mike Mattera

You need an M function to output a signal. That trips a relay (so you need to see if you have open/available contacts in your machine) to send the proper voltage signal to the indexer control box. Mike Mattera

Typically you might progtam from the front for horizontals, But you can do what James says and do the changes in the post. I believe most tutorials show horizontal machining as a Front T/CPlans for B0 and then going CCW, B+90 (right side) and so on. That's the way I teach it in my Training CD's. They also includes a horizontal post to get you started. Mike Mattera

That's a good one Tony. Mike Mattera

I'm guessing this is an A axis. You may also need to do an UnRoll of the 3d geometry in the Rotary substitution parameter page. I have a Rotary Training CD available at my web site if your interested. Mike Mattera
