General Mach Discussion / Automatic feedrate change during program execution

« on: September 06, 2013, 06:04:37 PM »

How can i get mach to change the feedrate while a program is running, I want to have the feedrate go from 5% at the start of the program to 100% at the end
this is for surface milling, when i start in the center of the job the feedtate is too fast and breaks the cutter. Standing there and manually changing the feedrate works, but some programs run for hours and i sometimes forget to go change the feedrate.
any help would be appreciated

General Mach Discussion / Lathe feed rate overide not working?

« on: January 07, 2010, 03:33:34 PM »

Hi everyone,
I have just revamped my "all in one" lathe screen and i found the feedrate override% values change in the DRO but during a cut it does not affect the feed rate
anyone else have the same problem?
my new all in one screen set can be found here

VB and the development of wizards / VB commands needed for tooltable

« on: December 29, 2009, 05:00:42 PM »

I have just completed my all in one lathe screen, now i want to add a wear offset calculation routine, that will read the current tool wear value and a userDRO contaning the wearoffset measured, then do some math and store the recalculated wear value back in the tool table

the code i will use to get the measured wear is something like this, but i cant fint the correct commands/veriable names

TWx=GetUserDRO(1201)     (read value from user DRO 201)
TW=GetWear....? (get wear value of X or Z from tooltable)
calculate new value for X axis e.g. (TWx/2)*-1 + TW
setWear.... = newvalue (store new value to tooltable)

Hope someone can help

Any comments welcome, good or bad  
Unzip and copy the Softlathe.lset in the Mach3 directory ie. C:\mach3\SoftLathe1v3.lset and the softlathe directory into the bitmap dir ie. C:\mach3\bitmaps\SoftLathe

General Mach Discussion / Turn Threading working at last

« on: December 16, 2009, 08:55:00 AM »

Thanks guys, threading in the latest version 3.042 032 is working great on my lathe, i had to convert back to index and a single slot
i have only tested it on a thread 35mm long and looking on a OGP CNC scope the pitch is only off by 0.008
for most applications thats fine.
I also did quite a bit of running between home and my friends house whom has Mastercam 9 and i managed to get the post sorted to post G76 code in Mach format
Feed back welcome  
In the post it asks some info for the program header, the defaults can be changed in the post, from line 706 and onwards, using notepad or any text editor
Friedrich

Update: Repaired C value that wasn't working all the time

General Mach Discussion / homing or toolchange macro help needed

« on: November 01, 2008, 04:17:07 PM »

Hi Everyone,
I am trying to write a macro that will move to a home or tool change position for milling
it looks like this

Feed=GetDRO(18)
ofset=GetDRO(0)    - This must read which coordinate is active G54, g55, g56 etc.
code "g54"             - This must set G54 (Machine coordinates
Code "g00  Z0"      - This must move Z home (or tool change position)
code "g00 x0 y0"   - This must home X and Y
SetDRO(18,Feed)  - this must restore feedrate
setDRO(0,ofset)  - This must restore coordinate that was used before homing (this line seems to be the problem)

sadly this macro doesn't work
can anyone please help

General Mach Discussion / No toolchange

« on: January 01, 2008, 02:17:42 PM »

Hi everyone,
Happy new year.
I have just completed setting up my lathe with Mach3 v3.0
I have got the CSS sorted with the index pulse, works well.
I have a quick change tool holder. (infact 2 in front and 1 at the back)
I have setup the tools in G53
when I run my program the tool number stays on 0, enven though it asks for tool change.
Please help
