z axis speed Amada fo-3015NT
z axis speed Amada fo-3015NT
(OP)
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?

Compare the values you have to the picture and let me know.

Not too sure what to do. There are a few possibilities. Most likely is that is that one of the variables for the stroke length got messed up. I am sorry but I cannot remember exactly were it is but if you go into the "set laser" page or one of those buttons on the bottom of the cutting conditions page, you will find where it says x3000 y 1500 and z should be 200.
Anothere way to check this is when u first turn on the machine, retract all axes, see what z comes out at. Then hit the G50 and start. If the value changes, we are on the right track.
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
What I think is happening is the when the machine first references, it reads a slowdown limit switch and then looks to the Fanuc parameters for the stroke length, grid shift, etc. After the G50 the position reads some Amada parameters and that's what I think got messed up.
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
Your machine will have z = 137... it should be 200.

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.

RE: z axis speed Amada fo-3015NT
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

RE: z axis speed Amada fo-3015NT
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?
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
I wouldn't buy a cone without knowing.
Does the head still have the problem if you run the external cable (for testing purposes)
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
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.

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.

When the sensor is on, the cutting head starts at the home position, travels down to Zero + Thickness + 1" and then turns the sensor on to start "looking" for the material.
What I am proposing is, starting from the home position, going to zero + (-2.5) thickness then + 1" to turn on the sensor and start looking.
On another note. On the utility screen there is a button for 2nd machine position. Does it have a place for a "z" value? I have never used this feature before but it could certainly mess up the position for home.
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
Super easy experiment.
Put the machine in 25% speed
Set the "thickness" to -2.5"
hit save.
Call up your program.
Turn the shutter key off the first time around.
Make sure the trace light is NOT on. (sensor active)
Hit start
Keep you had on the stop button just in case.
Keep in mind that its very cool you have an interest in your machine, how it works, and making it better. Your also saving your company a service call, possibly. Most operators would have give up about 39 posts ago. And, You helping me procrastinate from my paperwork.
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
For example, if you are cutting cold rolled 16 ga, your m102 will say, M102(CRS0.060). I would manually call up that file, then put in the -2.5 then hit save.....
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
So, no, to answer your question. The M102 stays the same. It the cutting condition that you want to change, not the program. The other day I asked if the program has any z values. The program should have nothing to do with controlling the head motion.

What about the "2nd Machine position" on the Utility screen?

Oh, one quick thing, What if you put a G90 G92 X120.8661 Y61.0236 Z7.847 in the program.
I know... It goes against my moral fiber to put a z in the program. Its just in the name of science.
RE: z axis speed Amada fo-3015NT
Head will come down at the maximum allowable speed in trace mode (i.e it's sensing all the way down)
now slip the ruler between the sheet & the nozzle (shutter closed)

If you the WACS head you should test it if you haven't already.
It's a bit of cash especially if it's not the problem.

About 50 posts ago i mentioned if the cable was a home made job or genuine Amada, did you confirm this?
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
Compare the resistance or the 2 cables, end to end of the inner & shield, & check the inner to outer on the faulty cable, maybe the shield is touching the inner core?
Now id be focusing all my attention to the coaxial cable.
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
I suspect that when you changed from the internal wire to external wire. You changed the status of the switch that tells the machine which cone is on there. When it's going slow, it thinks it has the 10" cone on there. Now, the machine thinks it has the 7.5"lens set up.
You can confirm this theory by looking at the z position. I bet it's back to normal.

It's enough to do ones head in.
Anyway glad it's resolved.
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
RE: z axis speed Amada fo-3015NT
My idea of what happened, and even that doesn't add up completely, goes like this:
When the guy cam in to replace the short z sensor cable in side the head, he broke, bumped it wired a switch incorrectly. The z sensor internal wire is right next to two switches on the very bottom of the cutting head. One of these switches tells the control the cutting cone is on, the other tells the control that the 10" lens adapter is on. As I previously stated, which no one read, the ten inch lens adapter off sets the z axis by 2.5 inches making the stroke length that much shorter.
So, to put it all together... The program starts, the head starts to comes down, the control looks at the " the thicknesses " adds one inch to that number and turns on the sensor. Now, the z axis is offset by 2.5" because a mechanic is not careful, plus the standard one inch, plus the thickness and turns on the sensor and traveled very slowly downward looking for the material. (How many times have I typed this?)
The part that is missing, and I am not sure how or why it's missing. At some point the machine should have generated a "lens not correct" alarm. I can not imagine how the mechanic could have bypassed this function/error code.
My point is, not the machine's fault, mechanic's. I hope no one got charged for the service call.
My other point. I like helping people out. I like to think I know a thing or two about these machines. If I am going to keep contributing, give me a damn purple star, read what I write, if you don't understand, ask questions, do the experiments I propose unless you think you are really going to break something, report the results. I am paid professional, just not by the forum.
RE: z axis speed Amada fo-3015NT
LASAERNINJA you nailed the problem on the very 1st comment, & I just over complicated it.
The part I missed is that the head was travelling at high speed in the down direction then switching to sensing (slow speed) 3.5" before it was supposed to. there should have been about 4.5" of high speed Z travel before switching to sensing.
I was convinced it was a coax problem, the very 1st comment that it crashed every time indicated to me that the responsiveness or calibration was out, if the sensing is coming on a few inches early the last thing I would expect is a crash.
