Post help for prototrak

[Tom Matuszak from McCann Technical]

Hi all,

 

I am hoping someone here can help with a problem with code for a Prototrak. I am not sure if it is something I am doing inside Mastercam or a post problem. The code is posted like this:

It will not load with the ( SET NEW Z! ) lines. If I take them out in the editor to look like this it loads great

I have edited the post to include the G130 and G131 lines as that was a problem at first as well. I know it is not that big of a deal taking those lines out but when you are working with high school students it presents a small problem trying to explain why they have to take the extra steps. We are not to the point yet of working with posts so for the younger kids it would be a mess. The post is below. I see where it is getting the SET NEW Z! but I have no idea why it is doing it.

Thanks,

Tom

# ------------------------------------------------------------------------

#

#Canned text:

# Entering cantext on a contour point from within Mastercam allows the

# following functions to enable/disable.

# Cantext value:

# 1 = Stop = output the "M00" stop code

# 2 = Ostop = output the "M01" optional stop code

#

#

# NOTE:

#

# Even though this is a 2 axis post enter a depth and rapid height when

# programming pockets and 2D contours.

#

# At the beginning of the program it needs a program number. The name

# of the program (use a number) will be the program number at the start

# of file. This will allow for a progno up to 8 char. long.

#

# Example:

#

# Name of program 12345678.MX2

#

# PN 12345678 G20;

#

# Program must have a MX2 extension for machine to accept it. (12345678.MX2)

The problem you have is not really a post issue but you can correct it via a post edit.

You need to understand your ProtoTRAK control a little better.

 

You are trying to post out a program in the Event based format.

The Event based format doesn't support comments.

 

Specifically, what ProtoTRAK Machine and Control are you trying to post code for?

The newer models can actually take G-Code and translate between various control systems.

[Colin Gilchrist]

Tom,

 

First, make a backup of the post. Then just put a # character in front of the line that outputs the "new z" statement.

 

That should remove those lines of output.

 

Thanks,

 

Colin

Colin,

I tried that and the nothing at all was posted and I got a ton of errors.

 

Tim, It is a EMX control 2 axis fairly new as we received the machines just a couple of months ago. The post does not give you the .CAM code. It gives out .MX2 code. I downloaded files both CAM and MX2 from programs on the machine and the post we used gives us code very close to it except for the darn SET NEW Z lines. I was thinking it may be something with MISC values in Mastercam but I changed those and nothing happened.

Have you tried asking your reseller?

[Tom Matuszak from McCann Technical]

Jim,

He did send me the post and I fiddled with it until I got to this point. Now I am stuck in mud. I think I have been looking at it too long.

Tom,

 

The MX2 format doesn't support Z positions at all.

It's strictly 2-axis so I am assuming this control is mounted on some kind of bridgeport type of knee mill.

 

Pay attention of the !z$ in both pz$ and pzrapid$ .

The ! suppresses the Z output.

Simply REM out the Z line like Colin said and you'll be OK.

Tim,

You hit it on the head! Thanks! My mind will be clear for a long weekend up in Wells Beach ME (not that it is going to be beach weather around here!) I took all the Z values out in the Mastercam linking parameters and POOF. Got just what I was looking for. I only have one now at the very end that does not seem to matter. One little renegade N50; line number that I need to get out of there. That should be easy.

Tom,

 

What you may want to do is modify the pz$ and pzrapid$ postblocks to output a program stop.

This will allow the operator to adjust the Z depth manually on the machine and simply press cycle start to continue.

[Newbeeee™]

Different control but on our smx 2 axis, we worked with our reseller and have all Z moves output as 'Set Z#' where # is the program depth value.

So for example, we can do some involved parts programmed in mcam where the machine will rapid to the plunge position and stop saying 'SET Z-.50' so we plunge 0.5 and press go and the machine runs to the next Z move where it says 'CHECK Z' so we wind up the quill, press go and repeat etc.

So we can do work which would normally be done on a VMC (talking prototypes here).

By memory IJK's have to be output as the machine doesn't like R's, and also compensation was a bit of a nightmare because whatever happens, the machine also applies its own roll on/off. So we can prog in mcam and have a lead in of whatever, post it and NCPlot it and all looks good, run in machine and the machine rolls onto the programmed roll on (ie double roll). Caught me out in a tight space - gouge!!!

Having previously worked for a reseller for over 5 years, I find this EXCEEDINGLY difficult to believe, I know first hand what they have access to so that they can provide posts. And a generic IS available

 

SO......
