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?

I don't think adjusting anything on the sensor board is going to help. Check your 'thickness" on your cutting condition page. Also, check the "follow start height" on the laser set page. I think the sensor is coming on too soon. Keeping your thickness to what it should be and setting the start height at 25.00mm should speend it up.

we had ours set on .3937mm. do you know if there is a setting to adjust the speed that the medium and standard settings are?

So, I made a mistake. The machine I looked at today was set to the same value. That must not be it. It sounds like the sensor is coming on too soon. Usually, one inch above the "thickness" the sensor starts looking for the material. I have attached a picture. I am not as cool as laserdog, I can't insert it in the text.
Compare the values you have to the picture and let me know.

laser ninja we have the same numbers as far as follow height through chute

I do not recommend cutting like this but see how it behaves with the "trace off" does it go slow? Are you seeing this on all different cutting conditions? When the machine is retracted / home, is the z axis at 7.876 or close to it?

it doesnt lower with the trace off just welds from way up high, and when retracted it is at 5.370. so far it does it on every material

Ahhh. I believe that's it. Your z axis seems to be about two and a half inches off. So, material thickness + 1" for the sensor to turn on + being off by 2.5". The sensor is turning on way up high and slowly, slowly coming down to find the material.

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.

Have you changed batteries or anything recently? any chance the enocoder has lost its memory?

On most Amada lasers, the batteries are for the B-axis only. The Quattro, and the M2 use batteries for all axes, I believe.

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.

ok i found all the perimeters but can't find stroke length anywhere. Absolute z reads 5.37 and machine reads 7.875

It sounds like you may be in the "current position" page. I am thinking cutting conditions page. "SET LASER" "MACRO" "AIV" look through those buttons as see if you can find anything. One of them says "calibration position" i don't think that's it.

Your machine will have z = 137... it should be 200.

ok i checked every button under condition and the utilities page and still nothing. it wont let me into the set laser page without a password?

nevermind i got in. it has set gas time for z upper stroke? at 1.00

Okay, all is not lost. Tomorrow I may be near a machine like yours. I will look around and see what I can see. In the mean time, when you start the machine tomorrow, go in to that "current position" page and see if all the Z's match after you retract. I am not opposed to posting the password for all the world to see but if I don't have to....

I understand completely i am posting a picture of the page. The password was pretty simple to figure out though thank god lol

WOW. That is not at all what I expected to see. Ummm, I am going to have to think on that for a while. Sorry...
