Anyone tried to modify .ini file for higher than 60 IPM

[jeffrey001]

I just would like to try a bit more than 60 IPM, maybe 65 or 70 IPM

Can't find how to change that in the .ini file

Look like an easy thing to do on the mill but with the lathe can't find where to insert these mods.

Any help would be greatly appreciated, Jeff

C&P from another post.

I got a 2.4.2 announcement email earlier this morning.

From the email:

NEW KEY FUNCTIONALITY:
• Slant PRO rapids are increased from 60 IPM to 100 IPM

Not sure if you want that much of a change, but comparing the two might give you an idea on what to change to get your desired results.

If you are running v2.4.2 or later you can issue the command ADMIN RAPIDS SHOW and it will display the current settings, ADMIN RAPIDS SET xxx to set the new speed. I am pretty sure you can select from 60 to 120. No need to modify any .ini files.

I have been running 120 in/min since it came out in beta and have not had any issues.

I will update Pathpilot and try this.

Thanks, everybody

Let me know how it works out for you. I still haven't updated.

Work great so far,

I tried many way to enter what as been said "ADMIN RAPIDS SHOW" but got an error each time. Spaces, no space, underscore between each words

But the 100 IPM is cool

Finally updated mine today. She's a little screamer now! I'm going to need to hone in my reaction times to let off the shift key when moving the tool around to set zeros.

Now, if we could just speed up the turret.

I'm half tempted to edit all of the g-codes to remove the coolant and spindle off commands. The tool is now sitting there waiting for both before anything happens.

I couldn't sleep without trying it.

I have a program that runs like clock work. From hitting cycle start to the first tool coming back around and setting Z0 position after part is complete, has always been 5:04.

With just the update, it dropped to 4:56.

Edited all coolant and spindle off commands to stay on and time dropped to 4:47.

Eh...1/4 of a minute per piece. 1 "free" part per 20 made. Better than nothing!

I've contacted Tormach about how to go faster than 100 IPM and they won't help.

Oooo....just noticed the backlash settings. I might have to play with that a bit.

I posted this in another thread after looking at the lathe code posted by sprutcam

Quick question for mike or other readers.
The post looks like it uses g96 command in a way that would make machine start with a slow surface speed because the tool is changed at max x travel. Then as tool rapids into lead in position the spindle would want to spin up to match the rapid move!

Is this how pp conversational works?
Or Is this how other machines and posts work?

if so would this not put un needed stress on spindle motor trying to change and keep up?
Looks like machine should stay in rpm mode g97 until rapid move is over and it starts normal tool lead in. then switch to g96 and continue.
Is this correct or am I missing something?
Any help would be great

After more research
CNC Programming handbook details this to be the correct code format using the g97 then switch to g96 and continue.
this would speed things up a bit imho!

This does not effect these machines much from what I can tell at this point. Most the long fast moves are along z axis. Im guessing this is detailed in cnc programming handbook because some machines with big hp power and power demands would stress if this is not addressed.
