Problem- Post issue to haas

[BartD]

Just bought an existing business with mastercam 6.1-7-8. Haas lathe and mills. My programmer is having issue when we send posts to the lathe. An example is this. To turn a 1 inch diameter the post should read x1.0. The post is coming in off of the radius or I mean that it comes in x.5. We have 4 posts to choose from. We have tried changing the parameter to zero ofset and back. Cutter comp left, right, and center. I am certain we are missing something simple. As for the software we will upgrade as soon as possible but the previous owner did not keep up with service payments or much anything else.

check in post
dia_mult : 2 #Multiplier for output on X axis

Ok, then we will find this in the post in DNC, or the post software on mastercam. I will check this as soon as possible.

I extracted line from mastercam MPLFAN.PST

I double checked the post file first thing this morning. Unfortunately for us it is exactly as you suggested. Any other suggestions would be appreciated.

referenced variable is user-define variable. it can be used or redefine to another one for output. it may be not used at all even just declarated in post only.
perhaps variable scalex used in your post? mastercam post language quite flexible for output X in diameter size depends how post was wrote

Changed value to 4. We are now cutting appropriate diameters. Thanks. Next problem is threading cycles.
