Output M41

[kunfuzed]

What's the best way to output an M41 to kick our Haas into low gear when cutting at 1500rpm? Right now our posted code looks like this:

 

T1 M6

G0 G90 G40 G80 G53 Z0

G0 G54 X0 Y0 S1500 M3

G43 H1 Z.1 M8

 

Here's what I've gotten to work at the control:

 

T1 M6

G0 G90 G40 G80 G53 Z0

G0 G54 X0 Y0 S1500 M41 <---- CHANGE THAT

M3 <---- ADD THAT

G43 H1 Z.1 M8

 

How should I be doing this and how can I get Mcam to post it out? If it's a post mod, we'll have to send off to our reseller since I don't think they'll let me mess with it.

 

Thanks guys!

My Lathe had 4 gear steps. That what I do is following.

I set in each operation a max speed value and according to this max speed my post sets the gear step.

 

prpm #Output for start spindle

speed = speedrpm

if speed = zero,

pbld, n$, *spindle_l, e$ #RPM = '0', output just an 'M05'

else,

if maxss$ <= 170, pbld, n$,"M41" , e$

if maxss$ > 170 & maxss$ <= 355, pbld, n$,"M42" , e$

if maxss$ > 350 & maxss$ <= 680, pbld, n$,"M43" , e$

if maxss$ > 680, pbld, n$,"M44" , e$

pbld, n$, *sg97, *speed, *spindle_l, pgear, e$

It is a post mod, but a relatively easy one to do.

Thanks for the idea. I'm not afraid to try it, but our work is pretty policy driven, so they'll eather like the idea and have our reseller do it, or just say screw it and program it for 1200rpm.

Thanks. I was hoping it could be done with canned text somehow. I'm not afraid to try the post mod, but my work is pretty strict about stuff so if they like it, they'l send it off to our reseller, and if not they'll probly say screw it and run the tool at 1200rpm.
