Haas tool change position

[Matthew]

Hello all.

 

We've recently added a 5ax trunnion to our VF-3. This combination does not leave a lot of room for tool changes. I'm curious if it's possible with Haas to force it to run a specific program for tool changes. I believe this was an option on Fanuc controls with a parameter change. Looking through the Haas manual I see I can alias M codes that could this, for example call M106 instead of M06 and have it run a program that would position the machine and then call M06. This would work for posted code, however I'd also like it to work for the ATC FWD and ATC REV functions on the control. Anyone have any ideas on this?

 

Thanks,

 

Matt.

I had my post modified to have a g28 y0. and then a g53 x-50. (pretty sure) hard coded into the Haas 5x generic post. So the table comes all the way forward in the Y and all the way to the right in the X. It works pretty good. It got the trunnion as far away from the tool changer as possible. The X-50. will change relative to the size of your machine. So yours should be X-40.

I know that's one option which will work great for posted programs. I'm also trying to failsafe against us calling a T or P number and pressing ATC FWD.\

Have you checked with Haas? I wouldn't know how to do it, but I would assume they could set something up that, no matter how a toolchange is initiated, it would run thru some sort of macro to position the table before any tool change occurs. That would eliminate the need for post mods and idiot-proof the ATC forward or ATC reverse toolchanges, which is what it sounds like you're after.

Very good approach on your side, just can't help you with implementing it. Sorry.

Hi Matt.

 

Last place I worked we had the same setup as yours. I asked a HAAS tech the same question and he showed me the following:

 

1. Setting #7 = PARAMETER LOCK: OFF

2. Parameter - 210↓

3. Press emergency stop

4. Start with a value of -4000000 on VF-3

Change this value as needed. Maximum value will depend on your machine.

5. [Write]

6. Parameter - 211↓

7. Leave at 0, but may be changed if different Y tool change position is needed

8. Parameter - 266↓

9. ZERO AXIS TC (bit #4) (X axis) = 1 [Write]

10. Parameter - 267↓

11. ZERO AXIS TC (bit #4) (Y axis) = 1 [Write]

12. Clear emergency stop

13. Setting #7 = PARAMETER LOCK: ON

 

 

For reference, for no movement at tool change:

1. Paramerter 210 = 0

2. Paramerter 211 = 0

3. Paramerter 266 = 0

4. Paramerter 267 = 0

 

 

I hope this helps. It did the trick on our machine. It has been a while since I worked there, but I do believe even ATC FWD and ATC REV will cause the machine to move to the safe position.

 

Good luck!

Thanks a lot Bob, that did the trick!

so when you do a power up start it will move to "ref 0" then move to a tool change position before it calls tool#1?

[Matthew]

We have the tool change on startup disabled so I'm unsure what happens in this situation. It seems to move to that position whatever I do for a tool change, M06, ATC FWD, all the probe macros since I'm sure they are using M06. I might try it out one day, but for the moment I'm just going to leave the tool change on startup disabled.

[JAJBILLET]

use M16 instead of M6.

This will call a subprogram (#9000) with the exact coordinates that you want. Once you edit this program (#9000) in the controller its always there. Just change all your M6 to M16 when you need to.

Kind of an old post but i hope this helps.

lol, 2011 question

I'm using this right now. Don't want to crash my tool into the rotary axis. That would be bad.

You have to appreciate the willingness to help even if it is almost 5 years later. Might be helpful so someone else down the road.

I can't get my X axis to work on my Minimill. The y axis seems to work fine.

Rocket, not working at all?

it was just a tip of the day from Haas a little while back

[Rocketmachinist]

No movement what so ever. I tried a bunch of different numbers for the offset value and I still get nothing.

[Machineguy]

seen this before, check the limit switches under the table. It might be loose or broken.

Can you move the axis with the dial?

There is a override in the control, but be careful. Its in the setting menu.

[Rocketmachinist]

I can move the axis with the dial. It just doesn't want to do anything then I have TC Home turned on in the X axis. I'm not saying the machine is broken and won't move. It just won't go to the newly assigned tool change position in the X axis when a tool change is called. Setting 266 bit 4 is turned to 1 and tool change offset is set to -16000000.
