Partner 1 Tool Change problem

[bocko912]

Got home last nite and when I fired up the CNC my Phase converter lost 3 start caps. I am in the process of fixing that when I get that fixed I will try the MDI. Yes there are air lines coming off the pancake cylinder for tool release but no other lines. Also there is a electronic brake on the end of the spindle motor it is activated by wire #'s 64 and 65. There are 2 small levers on each side of your spindle motor at the top. These are to manually engage and Disengage Spindle motor brake. I will let you know how it all turns out.

Thanks John

Just finished fixing my phase converter and finally got a chance to try the M19 spindle orient. Spindle turns at last programed RPM but never stops. You can't even stop it with spindle stop you have to hit Estop and reset drives. Sounds like it is not getting a signal from the prox sensor on the spindle. I can move Tchanger in and out and rotate it CW & CCw but I cannot home it.
Thanks John

I am referring to my knowledge based on my 1995 era Partner 1E .
It sounds like you have multiple issues besides tool change problems .
If you cannot stop the spindle by hitting the spin stop on the panel , then I would say that is the first thing to tackle .
Keep in mind that these earlier machines did not all have tach sensors for RPM
( making hard tapping impossible ) .
You could program the z to push a drill down with the spindle off , and it will
happily crash drills all day !
Look at your main screen . Does it say which tool is active ?
And does this active tool # change if you rotate the drum ?

My machine is a 1D Manu Date says 052. I am assuming 5/92. Spindle stop works when you program an M3 spindle speed. The only time it will not turn off is when you do an M19. Machine does tell you what tool is active but I am pretty sure it does not change when you rotate the drum but I will double check tomorrow.If the spindle turns when you do an M19 why does it not stop when it lines up with the prox switch in the head? Do you think it has something to do with the homing of the tool changer. I still do not have a home button on the Tchange page just CW CCW.

Sounds like the tool-change macro has been disabled (maybe because some part of the tool changer was not working and they wanted to run it with manual tool changes?)

Try changing the Power parameter "M6 (Tool Change) Macro to A:\TC\P1-6.ATC (or something like that) You will need to escape to the main menu and cycle power to get the control to load the macro.

After changing the the param try running a short program "T1 M6" in block mode, you should see the macro blocks(g32/m19/m21/etc) being executed.

You may have other parameters that have disabled your Carousel-Home(M20), Orient(M19), pocket-count, etc. You should have a parameter disk that you could load? or maybe a hard copy of parameters? If not Milltronics probably has a copy of the original parameters.

I think you are correct about the tchanger but I think what he did is load params from a P1 with no tchanger. I did not get a params disk with the machine when I bought it. I am assuming the tchanger macro you are suggesting is from a disc that I do not have and no hard copy of params either. I have no way to home the Tchanger as it will accept the M20 but does nothing and M19 just turns on the spindle and never shuts off. I did get into the Turret params and everything is set to 0 except Turret pocket count is 6. I think I will try to call Milltronics tomorrow and see what info they can give me. Maybe they will have a params disc. Thanks John

I talked to Milltronics today and one of the reasons my TC does not work is that The guy took off the spindle brake because it did not work. On my machine there is a prox switch mounted in the head by the spindle when it sees the set screw it activates the brake on the spindle and stops it. I do not have an air cylinder in the head of my machine just a brake on the spindle. Without the brake working correctly the spindle will just keep turning because there is nothing to stop it. So I will have to get this working before I can go any further.

Thanks John

I still say try switching 2 legs of power input coming in. If you have this backwards, it will try to drive the changer the wrong deirection. I have done this, and argued with it myself. So try it.

edit: nrmind, just saw more posts I missed.

Hi

I am undergoing through the same problem.

==> After M19, my spindle orients properly but it jerks suddenly

==> Also if i rotate the Clamped spindle by hand it moves 2 to 3 degrees & again tries to restore its original position.


I think i should increase the clamping force on spindle after M19 - BUT

1. Is it possible to change through Parameter Setting ?
2. What is the recommeded force ?
3. What is maximum force & need to know if any consequences are there if the force exceeds maximum limit ?

Thanks...Need Help Urgently.

Also attaching a parameter dictionary for easy refrence.
