2010 screenset

[Splinterdone]

Hello all am trying to get my router prepped for the 2010 screenset. My breakout board has only two available pins left, I have been told I can daisy chain limit switches to one pin leaving one pin for the fixed and mobile touch plates. My question is will limit switches serve for the auto zero requirements ?

As long as you setup your limits as both home and limits, it'll be fine.
You want to use them as home switches to have a repeatable position for the fixed plate.

Technically, you can get away without them, if you can ref your machine in a consistent location each time you turn it on. But having home switches makes it much easier.

I am having a different problem with 2010 screenset. It is not probing correctly. When I do a simple auto zero it touches the zero plate then retracts to machine z-zero and a warning pops up which reads: Warning: Z Clearance Plane is Above Z axis home switch....... and it does not zero properly. Z-zero is set 2" below the limit switch. Clearance plane is set at 1".

I am using an XHC Mach3 controller which has its own zero routine within its Plugin. Running Mach3 V R3.043.066

Are you homing the Z axis before running the auto zero? And is machine zero at the switch location? You shouldn't see that message if machine zero is more than 1" above you're zero that you're probing to.

Z zero should be set before it retracts, and before that message is displayed. If zero is set incorrectly, my guess would be with the plugin for your device. 3.043.066 is also known to be very buggy. I've had a few users in recent weeks that had problems with that version. Going back to a previous version fixed their issues.

I installed v3.043.062 and it did not help. I am referencing the axis prior to doing anything with the machine. It is programmed to come off the home switch 2 inches. When the bit touches the movable plate the z-DRO's do not change and it does not retract correctly (1/2 inch). It seems that it is not creating or storing a "ZNew". It retracts rapidly then stops. After retracting the Working Coordinate DRO changes to the plate thickness and the error message pops up.

Sorry for the late reply, I was away camping all weekend.

It is programmed to come off the home switch 2 inches.

How are you doing this? Where is Z zero in machine coordinates, and where is this relative to the plate. Is it at the switch? The macros assume the Z zero in machine coordinates is at the home switch, and the error message is to prevent the Z axis from crashing into the switch or tripping a limit switch. I need to know where Z zero is in machine coordinates, and how high above the auto zero plate it is?

It seems that it is not creating or storing a "ZNew". It retracts rapidly then stops. After retracting the Working Coordinate DRO changes to the plate thickness

Is it touching the plate twice, or just once? If it's only touching the plate once, then it sounds like noise is triggering the switch above the plate, which is when you see the plate thickness in the DRO.
It should touch the plate, back off slightly, then probe the plate again. At this point the DRO should read the plate thickness, and then it should back off an amount equal to the clearance plane.

Try entering a very small number for the clearance plane, like 0.1".

Also, make sure that "material offset" is not checked on the toolchange tab.

Z-zero is 2 inches below the limit switch. There is an option in the plugin for doing this. It backs off the switch a pre-programmed amount then sets both machine/work coordinates to zero. I shall try setting it to simple zero so that it is on the switch when it is at zero. Zero currently is 4 inches above the touchoff plate. There is not any noise in the system. I have dealt with noisy systems before. It actually touches the plate every time.

Enjoy your weekend. Don't worry about this until after the camping trip. I wouldn't want to get crossways of the boss.

I'm already home.

You didn't answer, does it touch the plate twice when probing?

Can you post your .xml file so I can look at your settings? Unfortunately, I can't test without having your motion controller.

[rbraeking]

It only touches once. I can't understand the problem because the sub looks like it should work. The sub the card mfg sent is attached. I had to convert it to imperial but it works when I call it M889.m1s.

[ger21]

With my macros, if it's only probing once, then either noise is triggering the input, or the motion controller is not doing the probing properly. To me, it sounds like noise.

I'll look at your .xml when I get home from work.

[ger21]

Your .xml file appears to be kinda messed up.
Why do you have 6 axis enabled?
You have the spindle setup as step/dir, but no dir pin # assigned?
And why is the index input sharing the pin with the probe input? Are you using the index for something?

[rbraeking]

The .xml is the one the card mfg sent. They go up to 6 axes. I just hadn't bothered to "x" the extras yet. I think the .xml was written for an earlier card and not updated for this one. The probe/index were sharing as a diagnostics tool. The spindle only needs step because I am setting it up for PWM. I hadn't finished that setup when I copied the .xml. I'm also going to try slowing down the kernel speed. 45 seems a bit on the overkill side.

[ger21]

Kernel speed setting in Mach3 should have no effect when using a motion controller. There should be a similar setting in the plugin settings, unless the card has a fixed max frequency.

Personally, I'd start with a clean profile and setup only what you need, rather than using an .xml with a bunch of incorrect settings.

I still believe the issue is either noise or the plugin. Every case I've seen where the tool only probed once was due to noise.

Typically, if the plugin does not support probing correctly, it results in a crash (from what I've seen).

I am trying to do it by the numbers manually. It will probe with a string like:
G90
F10
G31 z-6
It probes down to the touchplate and stops. I reset the work DRO to zero + ZPlate. Then I retract Z0.05. All is good so far. That is when I get trouble. I enter "G31 Z-0.25" and the machine just laughs at me. If I retract a full inch it will "G31 Z-2"
The mfg's probe sequence uses OEMDro(1001) instead of UserDro(1851) for plate offset. I'll try making that change.

Indexing is not quite what I am used to with this card as well. It stops on the limit and resets the DRO's to zero. Or I can set it up to come off a certain distance then set Dro's to zero at that point.

Gerry,

Here is my rewrite of the Chinese probe macro. It works like the 2010 simple probe but without the bells and whistles. Anyhoo it will get me to Z-zero at the surface of the material but I have to do it again on every tool change. I would much prefer to use your macros if I can get them to work.

Bob

[ger21]

If that code works, then I don't see any reason why the 2010 macros don't work.

Did you try setting the clearance plane to a very small number, and see if you still get the error message?

[rbraeking]

I agree. Something is not jiving....just don't know what.

I'll try that.

Bob

[ger21]

Do me a favor. Connect a short 3-6" wire (as short as possible) to the probe input. Run my macro and short the wire to ground to simulate the probe making contact. You should see it probe twice. If it does, then noise is triggering your input.

[rbraeking]

OK. I'll give it a try, but I already did that by hitting my hockey puck against the frame previously in my diagnosis procedure. I can do it at the card as well.

[rbraeking]

Gerry,

I think my problem is that it is triggering a ClearAllow >/= 0. Is that the SafeZ in Config/SafeZ Setup or is it the Clearance Plane set in the 2010 screenset tool change tab?
