Gang Tooling auto tool change

I'm trying to learn how to run a lathe on Linuxcnc. I'm using an old pc with BOB, and some drivers/steppers for testing. I've also fixed up a small variable speed motor and 60 slot disc, with three opto isolators for index, spindle phase a, and spindle phase b. I've made progress, and have got a working configuration with quadrature threading.
Seeing the Z stepper following the spindle speed change on a G76 cycle made the effort of learning very worthwhile.
I've now managed to get the tool offset table etc figured out, and can run a program with multiple tools. The program prompts for a tool change as it defaults to manual. Looking in the HAL file, I see the toolchange is set for manual.
My question is what changes are needed to run a lathe with gang tooling, so that the program will run to the end without prompting for tool change. I don't need an auto tool changer, I just need the tool offsets to come into effect.

Thanks,

John.

I have got one of these (hence user name). Its in good order as I re conditioned it about 15 years ago (had bed strips re-ground, resurfaced under side of saddle etc). It does have a worn out leadscrew, and no gearbox, so would be a good candidate for conversion. My first priority is getting to grips with Linuxcnc.
Holbrook Minor sounds good, very high class!. I did reply to your first post, but forgot the code so not sure if it went. I'll make your chages
and let you know how I get on. It must be great to be able to re configure Linuxcnc, Thanks again for your help.

Andy,
Just tried your minimum solution. the three lines to be removed were longer in my Hal. I backed up the original, removed the three lines, added your single line, and it works perfectly!. I'm very pleased to have it working. I've now backed up the new file.
I'll look into your other suggestions, but I want to get some gang tooling programs up and running first. Thanks again.

This is literally years ahead of me entering the world of LinuxCNC. But this thread appears to be what I'm trying to do.

I've been running gang tool lathes for many years and I'm currently rebuilding two of them to put back into service.

Is there any way for you and I to communicate so that I can pick your brain to make my machines do what you've done?

Thanks in advance,

Scot

I'm a few years late on this thread, but I'm trying to do basically the same thing with 2 lathes that started out as gang tool lathes and not conventional lathes.

The code is simple enough. But I'm unsure of where to put it in my files to make this work.

Any possibility we can elaborate on this subject?

Thanks,

Scot
