General Mach Discussion / Re: Return tool to tool holder when finish working.

« on: April 26, 2023, 07:16:07 PM »

It looks like you have a few problems :-

1. Make sure you have 'Tool selections persistent' turned on, this will remember the current tool over power downs , see image.  Click the tool DRO on the program run screen, enter a number and press return, exit Mach3 and restart, is the tool number still set?

2. This macro is for a rack type tool changer with no return function so we need to do one for your setup.

3. We need to know the position of the first tool holder relative to the home position and the pitch spacing of the tools.  Output used for the tool release, output used for dust shoe lift if fitted.

With this info we can start and fix your problem.

you can call T0 M6 and then the script can just put the tool way, the M6Start.m1s code may need to be modified to do it.

Post your script and we can take a look.

Post your code so we can see just what it is doing.

Are you set to feed per minute or feed per rev?

G97 S1000 M3 will set the spindle speed to a fixed speed of 1000 RPM.

G96 S200 M3 will set the spindle speed to 200 feet or 200 meters a minute based on the cutting diameter and will adjust the speed as the diameter changes.  Tool diameter offsets have to be set correctly too.

Just typing G97 will not change anything if you do not issue a Snnnn M3 with it.

You could try this one I did many years ago for Boxford 125/160 lathes.

Rename the file and put it in the correct profile macro folder.

The macro that came with the machine looks good, it could be that the turret is sticking and needs oil,  You could also reduce the velocity on the A axis and up the acceleration time to stop any missed steps.

The second macro is not for your machine.

Make sure you have a % at the start and end of the code e.g.

%
O1234
X5 Y5
Etc...
M98 P 1235
...
M30

O1235
G01 X1 Y 1
...
M99

Go to toolpath in config and select the axis of rotation.

I would check that all the drive couplings are solid and not slipping on the motors and or pulleys.
