Formatting Reference Manual

By the way - Have you seen Appendix D? If not, YOU SHOULD! Check it out.

What is this manual and who is it for?

This is the second of two manuals written for Post HASTE – it contains detailed information regarding the

Post HASTE formatting templates.

This manual was written for people who are already familiar with the basic concepts covered in the manual

entitled Getting Started with PostHASTE. If you haven’t already, please read (or review) that manual.

What is Post HASTE ?

Post HASTE (sometimes referred to as “the post” for short) is a software system that translates your CAM

system’s tool motion output (CL files) into ‘NC program’ text (or ‘ASCII’) files to drive NC or CNC

machines. PostHaste can create programs in any of these formats:

•

EIA (sometimes referred to as ‘ISO’) standard :

EIA programs are the most common type of machine control files; they typically use G, X, Y, Z, T

and/or M codes (among others) for various machine movements and functions.

•

‘Conversational’ :

Conversational programs are usually somewhat similar to EIA programs, but typically have words

or phrases (such as ‘LINE’ or ‘ARC’) in place of some or all of the standard letter codes.

•

Tab-sequential (or “columnar”):

These types of programs are not very common anymore, but are sometimes needed for older (e.g.

‘Bandit’) or less expensive (such as Emco-Maier) machines. These programs have the various

numerical values arranged in columns (instead of using a letter); the location (or spacing) of the

numbers within each line determines the significance of the value. For example the first column

may be an X position, the second column the Y position, and so on.

Limitations of Post HASTE

Some machines do not use the above conventions and therefore PostHaste may not be suitable for use in generating

NC programs for them; among them are some Brother and older Mazak (‘Mazatrol’ language) machines and several

others. If you have any doubt as to whether or not PostHaste is suitable for your machine, then call us; we will be

able to help you determine its suitability. If it is not, then you may either purchase a postprocessor that has been

customized to the specific machine, or get as close to it as possible by configuring PostHaste, then editing the NC

code (using a text editor) to suit your machine exactly.
