z axis speed Amada fo-3015NT 3

[hookie1985]

Ok we had our internal z cable replaced in the head this week. "aka the short cable" but now our z axis is super slow when it goes in the negative. Theres no in between. we usually run on standard at a decent pace but now its so slow we cant, and medium is so fast it crashes every time. I know theres a pot by the main board that controls that. would anyone happen to know what it is?

 

[hookie1985]

lol thats what i was afraid of when i saw the numbers.. its all good. I just remember he said he did something to the "pots or pods" of the control board but i have no clue what. he had to flip a switch on one when they ran the long cable

 

[LASERNINJA]

Well, one other idea. Please check the program. Any program that you have run recently. Are there any "Z" values? There should not be.

Hookie,

If your still having problems i have attached the control board manual.
It has extensive information on the board functions, wiring & testing, so if you believe the fault is Related to the HS2000 board or coax this will shed light on the workings of the controller.
It doesn't say Amada but that's irrelevant, Hass make it for Amada.
good luck.

 

[hookie1985]

awesome i think the quick approach function is what he said he flipped. the programs have no weird looking z values i see anywhere.

 

[LASERNINJA]

Strange or not are there any z's?

 

[hookie1985]

Actually no there are no z's. it uses the material registered to set a height i believe..

 

[hookie1985]

I looked at the pdf but got a little lost. Where can i find my quick approach setting?

 

[hookie1985]

nevermind im dumb. i mis read that

 

[LASERNINJA]

Personally, I have never had to mess with the hs-2000. I have changed a few out that have failed but never gotten into the nitty gritty of it.

This is just my opinion. I would be more concerned with the z axis being off by two and a half inches. Did you happen to notice what the position was when you first retracted this morning? If it was 7", at which point did it change?

P.s. I think the HS sensor board costs about $6000

 

[hookie1985]

Yeah our board was just installed in june. the poisition at startup was 5.387 even after retract..

 

[ausman]

just a thought, have you tested another cone? WACS or ECO done then run the head cal program?
Also if someone flipped a dip switch on the board, did the problem occur straight after, any chance they flipped another dip switch by accident.
Was it a genuine cable from Amada or did someone buy some coax & solder it up?

 

[hookie1985]

We replaced the board and it did it and the tech flipped a dip switch to fix it. We were running our external cable at the time. Well now that they replaced our internal cable and the plate that it comes with its doing it again. I was hoping its not a cone issue as it was fine before he replaced the internal. But the tech swears he didnt flip a switch last time and we should just buy the cone. My boss has his foot down that they just want our money so im stuck in the middle trying to figure it out.. save me please haha

 

[ausman]

Have you got a WACS or ECO cone to test?
I wouldn't buy a cone without knowing.

Does the head still have the problem if you run the external cable (for testing purposes)

 

[hookie1985]

We dont have any other cones to my knowledge but i will try the external wire test tomorrow and see what it does for sure

 

[ausman]

Have you checked the responsiveness of the height sensing when the head is down in height following mode? ie when the head is down slip a thin metal ruler between the nozzle & the sheet and use it to make the head trace up & down. (watch your fingers)
Is it as responsive as usual?
If the responsiveness is acceptable then I doubt the HS board or the coax is faulty. id be focusing on a setting or parameter.

 

[hookie1985]

with the shutter open??

 

[hookie1985]

i taped off the button inside the cone and hooked up our external cable and it kept giving me a z wire break alarm. So im back to the internal cable running slow again

 

[LASERNINJA]

I don't know if it will work, I have never tried it. You could put a negative value in the "thickness" setting of your cutting condition page. If the software will let you put it in, it might prove that the sensor, cone, wire, and sensor board are all working exactly as they should. It would then point us to the z position issue I have been harping on.

Just a thought.

P.S. If you decide to try this experiment. Make sure your last column on the cutting conditions page is set to standard.

 

[hookie1985]

how do i adjust the z position? id like to give it a try

 

[LASERNINJA]

Its in the upper left corner of the cutting conditions page. It literally says "thickness" I would put in -1.0 first, then go to -2.5 if the negative 1 works.
