Fadal post question

[MBX5]

Running a Fadal 4020HT with CNC88HS control... I am using the "Generic Fadal" post in HSMWorks.... I have a few questions....

Below is the beginning of a very simple part:

(T2 D=0.196 CR=0. TAPER=118DEG - ZMIN=-0.7589 - DRILL)

.........................and so on

Questions:

1.) need to have line numbers in front of comments...do I need to modify the post for this?

2.) Is there a Fadal post avail specifically for Format 1 / Format 2?

3.) Line 100 has a G90 for absolute, but then 120 switches to incremental and a G28, but then 130 goes back to G90...

4.) What is happening is that the tool goes down to just above the part, moves around a little, the raises way up in positive Z and does the tool path work...not sure why this is....?

Any insight / help on this? Thanks in advance....

Below is code from a different part that I created in another CAM package that works well:

I used to own a Fadal 15XT myself.

The post you have is Format 2 (Fanuc style). The G91 G28 Z0 is used to send the spindle home in Z on fanuc type controls.

I suspect your control is in Format 1 mode, which is why you are having the problem. If you contact me I can help you.

That would explain it....thanks for the info... I am using Format 1.... I will go through the "correct" channels and see if my reseller can get the post...will let you know how that goes.

Thanks!

so how did it go with your VAR?

HSMWorks now supports Format 1 and it is in the library of posts as standard...I have sent them requests and bug fixes and they respond the same day...very cool.
