Emco 1998 turn 55 was created by gearshift
Hello, my high school has a 1998 emco turn 55 and we cannot figure out how to index the turret/ spin to another tool, I’m begging anybody who is familiar with the machine to give us a step by step on how to spin it, aux buttons don’t do anything and the t0101 command isn’t working either

Is it running with LinuxCNC or with the original controller?

If it is LinuxCNC then it might well need an M6 command after the T0101. (depending on how it has been configured)

It is using winMC so maybe? It looks like a black screen so I think it is the original CBC program that the machine uses and the manual refers to

Check out the emco user group.
groups.io/g/Emco-CNC-Users

I have the mill and they helped me back when i got it years ago.
They have all the manuals and even schematics for most of the machines.

Thats not to say someone here cant help, just another place to look incase.

Heres a quote from the manual
3. Turn on the PC, once it is booted the emco control software
should run automatically. (Note: if it doesn’t run, find the
’winnc’ software and run it.) If the lathe is running the
screen should appear without warnings. Turn off the lathe
for a few seconds and then turn it on again. An error
message should appear on the screen - press <ESC> to
clear it. If hitting <ESC> doesn’t clear the erro messages
ask the instructor for help.

4. There are two main display screen on the PC. The first is the
’operational screen’, which is called with <F1>. The other is
the ’display screen’ which will display machine coordinates,
it is called with <F12>. To see the general machine setup
press <F3> for ’PARAM’ details. Find the communication
type by pressing <F4> to give the diagnostics of the RS-485
port and the software version.

5. We must zero the lathe before performing other operations.
To do this first hit ‘F1’ and then ‘F7-ZRN’. A small label
‘ZRN’ should appear near the bottom of the screen. Press
‘4’ on the number pad of the keyboard - the lathe should
move in the ‘x’ direction. Next, press ‘8’ on the keyboard,
the lathe should move in the ‘z’ direction. After all motion
has stopped the lathe is calibrated, and it will be put in jog
mode. Function keys are the main method used for
inteacting with the lathe. As these keys are pressed the key
choices will be updated on the bottom of the screen.

6. You can move the lathe with the keys on the number pad as
well as perform other function. Note that many functions
can only be used with the door open or closed, and the
chuck open or closed as indicated.
4 - move carriage left (door closed)
6 - move carriage right (door closed)
2 - cross slide out (door closed)
8 - move cross slide in (door closed)
<CNTL>= - open/close door (spindle off)
<CNTL>‘ - open/close chuck (door open)
<CNTL>7 - turn spindle on (chuck closed, door closed)
<CNTL>6 - turn spindle off (chuck closed, door closed)
<CNTL>2 - turn on/off chip blower (door closed)
<CNTL>1 - turn tool turret (door closed)
+/- - increase/decrease feed

EDIT
A note, my machine was working but had to use a very old computer with an isa card and 800mhz cpu and 32mb of ram.
I had to solder and repair the motherboard due to failing caps.
I had to replace its psu as it too was bad.
The hard drive was failing so i made a back up of it and upgraded to a new ish one.

These machines have config files and key pairs that you dont want to lose. If you have a working computer make a backup of the entire hard drive and create a disk image of it.
After fixing my machine and running it stock i went the route of switching it to linux cnc.
As the hardware was very old and hard to find parts to fix it.

If you decide to retrofit the machine my advice is to leave everything intact and just remove the connectors from the main board to the stepper drivers, limit switches and vfd into the new brain board of your choosing.

3? You good, I replied to a topic then may have accidentally started one in the CBC section when I thought it was a CNC problem

Gearshift,

are you able to home the machine?
Can you move it in the x and y?
Also picture of the machine can help.

12. Each tool will have its own geometry, and each one must
be defined separately before running G-code programs. In
total, the lathe will store up to 16 tool geometries. These
can then be related to one of three/six positions in the
turret. When calling a tool in a G-code program use ’Txxyy’
where ’xx’ is the turret location of the tool and ’yy’ is the
geometry number to use. So a tool in position ’2’ in the
turret using defined geometry ’5’ would be called with
’T0205’. Put a turning tool in turret position 3.

I don’t know if the issue is the code we are putting in but the turret itself as even manually moving it is not possible without taking the cap off of the top of the turret. When we press ctr 1 nothing happens and I tried putting in the correct geometry and nothing happened, how do I post a picture without starting a new forum
