Need Help!- Rotary G-Code check..!

[xray34]

Hi All.
This is one of my first attempts at NC from scratch...

I have used Edgecam for a lot of my 3 axis very successfully
but a reliable 4th axis post still alludes me so.....

I need to machine this (see attached screenshots)

I have written the NC code for HURCO's BASIC NC (as I dont have ISNC option available to me)
(see attached txt file)

It cuts the part in increments of 1mm cuts (with the tool Z zero being at A axis center zero.)

NOTE: My A axis is mounted on the LEFT of my machine table for this particular part...

PLEASE could someone look at the code and give me some guidence and help regarding where I have gone wrong and possibly where and how I could improve it and maybe shorten it??

Many thanks for any help you can give me people. :-) :-)

You could shorten the program by using a main/sub program. I'm not a Hurco programmer so don't assume this is "gospel".

MAIN PROGRAM:

N10G90 G40
N20T1
N30S1200 M3
N40G0 X10.0 Y0.0 A0.0 M8
N50Z38.0
N60M98 P190050 (CALL SUB 50 19 TIMES)
N70G0 Z38.0
N80M05
N90M25
N100M02

SUBPROGRAM:

N10G91
N20G0 Z-1.0 (INCREMENT Z-1MM)
N30G90
N40G1 X-34 F250
N50A-90.0 Y-4.0
N60X-18.0
N70G3 X-18.0 Y4.0 I-18.0 J0.0
N80G1 X-39.0
N90G3 X-44.0 Y0.0 I-39.0 J0.0
N100G1 A0.0
N110G3 X-39.0 Y-4.0 I-39.0 J 0.0
N120G1 X10.0
N130G0 Y4.0
N140M99

Cheers dcoupar, not totally sure how that works on hurco's basic nc but will try. Thanks.

ALSO I cant seem to get the A and Y to move together, keeps saying 'syntax error in wrong mode'
any ideas people??
