setting up EMCO Compact 5 PC

I am not quite sure if this is the place to put this but anyway.

At school we have an old compact 5 pc that has lain dormant for a number of years and I am not attempting to restore to a condition that everyone can use it in (as opposed to using the old 486 that it had already).

I have jumped the octal latch ic with bits of solder and the old software still moves it so I am assuming that that fix will work. I am a little unsure as to what numbers I will need to put into EMC on the computer, as this is my first real interfacing project and I havent done much with cnc lathes before.

If anyone can help that would be greatly appreciated. Even if you can only point to some information that will help me learn some more on this subject.

Thanks in advance.

I would start by reading the EMC2 Getting Started Guide.

What numbers are you referring to?

Have you installed EMC2?

Is it a stepper lathe?

Yes I have read the entire instructions but unfortunatly a large proportion went straight through my head.

I have it installed in a coldswap setup in my computer at home and as soon as school starts again I am planning to install it there.

I think that the numbers are the ones for the stepper motors... speed, accelaration, etc. I think from memory that there a a numbere of presets there but because the lathe is so old I am pretty sure that none of those is a suitable representation of the lathe.

Once I get home I will check what EMC calls them.

Thanks for showing an interest

Each time you read them a bit more stays with you so keep on reading.

The drives have minimum timing requirements for step, step space, direction setup, and direction change. So step one is to find out what kind of drives the machine has and are they stepper drives or servo drives...

The power the motors have and the machine mass will dictate the speed and acceleration settings.

ok I have now got the lathe hooked up to a computer running EMC2.

however I now have no idea what the pins used by the lathe are, so if anyone knows what they are or where I can find them could you please post on here.

quelqu'un aurais t'il une config en millimètres qui fonctionne???????
je deviens fou a essayer de déchiffré les lignes de ces fichiers et quand j' essaye de creer un fichier ini par linux cnc, je ne sais absolument pas quoi répondre....

En fichier INI trouve cette ligne de texte (section [TRAJ]):

LINEAR_UNITS = inch

et remplace avec:

LINEAR_UNITS = mm

merci, j'ai finalement trouvé une version de INI en MM: Half-fullstepMorph_MM
téléchargeable ici: electronicsam.com/images/emco/linuxcnc_configs/

tout fonctionnait très bien jusqu'au moment ou j'ai voulu faire un filetage.
a la commande G33 Zn1 Xn2 K2.002, linuxcnc se met en attente sur cette ligne et me dit que le programme ne se se termine pas par"%" alors qu'il se termine bien par "%"et que le programme est "en marche" en ouvrant le statut de linuxcnc,
"velocity: waiting"?

Le spindle speed display affiche bien la bonne vitesse de 530rpm +ou- 2rpm
(l'affichage de la vitesse était trop variable alors j'ai pu lisser l'affichage en mettant
"setp lowpass.0.gain .001" a la place de "setp lowpass.0.gain .07".

Dans HALMETER: le spindle-ppr change bien d'état en tournant la broche, le spindle-index change bien d'état en tournant la broche.

je vous remercie d'avance pour votre aide, mes compétences s’arrêtent la.

Poster votre fichiers ini et hal svp.

[edit]
Aussi verifiez que 'spindle-at-speed' est active. (spindle/0/spindle-at-speed)

[edit2]
autre chose: pin spindle/0/revs doit augmenter 1 quand la broche fait un tour en direction positive.
