Dynapath Delta 2000 tool probe

[dreammstr6]

Has anyone used a tool probe on a dynapath delta 2000 mill controller? I have the manuals for the controller but I can’t get the tool probe to act right. Probably something I’m overlooking. I took a calibration tool and calibrated the probe. According to instructions it says to setup the probe use the calibration tool and move to probe until probe protect error. Take the z value and subtract reference tool length to get tool probe location. Done that then ran a g8 probe calibration cycle. With the length inputted. After that I tried calibrating a tool it calibrates but instead of being -1.3064” it calibrates to +4.3650 which is overall tool length from spindle nose. Now I have no way to reference part zero. And yes I have called machine manufacturer and dynapath with no luck on help. Any ideas?

What is the number that you input after calibrating the probe, what was the Z reading at tool protect and what is the reference tool length?

Probe protect at -19.6262 reference tool length is 5.6391 for the setup of the table probe I entered -25.2653. For the location of the probe on z.

 

[dreammstr6]

On another note if I run the g9 tool length set on the reference tool it does load 5.6391 into the tool table.

What tool length value is in your tool table for your reference tool before you do the G8 calibration?

Originally 0.0000 and I think I have tried with the actual length.

I don't have the probing option on my Dynapath system so I can't test here, but what if you set your reference tool as zero length in the tool probe calibration step since that is the tool you use to set your part zero?

I tried that thinking same thing. You can’t set the length expected length to negative values.

 

[cngbrick]

Can you set the table probe Z location to -19.6262? (essentially reference tool length of zero)

 

[dreammstr6]

Tried that also. It throws the controller off in finding the tool length. Fails probe cycle.

I ~think~ that's exactly what you want it to do, set the tool length from the spindle gage line to the tip of the tool. Then you use a fixture offset to set the Z level of the part. How are fixture offsets set on the 2000?

On the 2000 you go to menu 6 then e. Then choose fixture offset e01-e32. But it not correct. Currently I use one of the cheap led tool setters that magnets to the table. With reference tool at 0.0000 I set my z in the fixture offset and parts run fine. But using the magnet led tool setter my tools are mostly negative numbers and it works great. Using the probe to set the tools zero is no longer correct . If I take a tool that was set with the led setter and run it down until I get a probe protect fault on table probe my z with tool length compensation on is -19.6262 or reasonably close. Using the table probe z is not close to -19.6262 with tool length compensation on. I know I’m missing something.

If you put your 4.365 tool in the spindle without activating the tool length, then bring the tool down to touch the LED setter, what Z shows on the control? If you add the 4.365 plus the LED setter length what is the total? If you put that total (Z negative plus tool length plus setter length) into the E01 offset as a negative, does the tool go to the correct location when fixture offset and tool length are active? That's how my older Dynapath works.

What I’m noticing is as long as the reference tool is set to 0.0000 in tool table any length you set the -1.3064 tool too besides the correct-1.3064 z is off by the amount positive or negative different from the -1.3064. So if you enter +4.365 the bit will be +5.6714 above the part trying to cut. I tried setting the reference tool to its exact length in tool table but z hits it’s over travel.

I don't follow what is happening, I'd need to see the manual to help any further. I'm surprised Dynapath hasn't helped you, they've been very helpful for me every time I called.

 

[dreammstr6]

Tom at Zps was surprised also. But I have called multiple times on how to use the probe. Basically I have had to read the manual over and over and just try things to get as far as I am. Here are some pictures of the manual pages on the probe.

 

[cngbrick]

Can you take a picture of the display screens for probe calibration (just after you get probe protect error), G8 and G9? Perhaps someone familiar with the probe can notice if there is something different in your settings.

[dreammstr6]

Yeah let me get some parts done and I will. I’m having a hard time wrapping my head around why the z without tool comp and with tool comp don’t relate between the reference tool in t01 and the tool in t10 calibrated by probe.

The manual isn't making sense to me. Is that a Dynapath manual or a ZPS manual? The language seems sort of like a translation problem.

Dynapath delta 40m/50m/60m manual. I have 3 dynapath user manuals and the installation manual and a field training manual. But I agree not making sense. Zps doesn’t have any information on the dynapath probe cycle except what is in my manuals from dynapath. What is more shocking is dynapath couldn’t even tell me if the tool probe is supposed to setlength from spindle nose.
