General Mach Discussion / Re: Auto Tool zero. Which Input etc. do I Use?

« on: January 14, 2009, 03:15:04 PM »

This may not be the correct place and there may be a thread that address my problem but I can not get the Auto Tool Zero Touch Plate to work.

This is my set up.

I am not using any screen in Mach.  I have added an LED to my touch plate.  I have 2.5 volts to power things.

I am using the code that is at the top of the thread.  Before I run the macro from my Shuttle Pro, I touch the plate to the router or bit and the LED lights and I can see on the Diagnostic page that a complete circuit has been made.

When I run the macro, the router is driven through the plate and wants to continue.  It does not stop. 

What am I doing wrong or what do I need to change.  it would seem to me that I should be able to hold the plate in the air and once the router has touched the plate, it would stop driving downwards and set the Z to zero and move upward to stop.

Help please.  If you need additonal information, let me know.

Thanks
 

Sounds to me like either your "ports and pins" are set incorrect or the touch plate is not triggering a signal to Mach.

There is some potential for confusion with Mach's terminology.  On the diagnostics page the LED is called "digitise".    In "ports and pins" the input is called "probe"

If you are sure you have that setup correctly and Mach is seeing the probe input change state on tool touching the plate then try this,

enter G31 Z-5 F5 into the MDI and as the Z moves down activate the touch plate.  The Z move should stop when this happens.

If not then I strongly suspect that one of the aforementioned setup issues is in need of attention.

If you suspect that the G91 being active is doing something odd to the SS why not add,

Code "G90"

to the beginning of the homing macro.  Worth a try just to see what happens.

The way I have it is;
5V to 220 ohm resistor
220 ohm resistor to pin 13 - confirmed 5V on pin 13
pin 13 to copper plate
Probe activated as pin 13 active low, port 1
Ground from 5V supply to machine

That looks fine Olf20

The only thing is the BoB ground to machine ground.

If you start to get funny symptoms you may need to disconnect this and use a second wire with a crocodile clip for placing on the tool.

Most likely you won't have an issue.

Active low will be the setting you need.

General Mach Discussion / Re: home off distance to zero

If you want the homing sequence to leave the G53 zero a little off the home switches this is how I would do it.

Say you wanted each axis to finish homing 10mm off the switch but still be at G53 zero

Set "Home Off" at -10 in "Homing and Limits" on each axis

Use this as homing script.

DoOEMButton ( 1024 )
Code "G53 G00 Z0"
DoOEMButton ( 1023 )
Code "G53 G00 Y0"
DoOEMButton ( 1022 )
Code "G53 G00 X0"
DoOEMButton ( 1025 )


Do the same for the A axis if needed.

This will home, leaving the axis 10 mm off the switch and move on to the next axis etc.

General Mach Discussion / Re: Shuttle pro ad on screen MPG

« on: November 21, 2008, 03:53:04 PM »

When Art first wrote the plugin for the shuttle he had the centre wheel default to continuous mode.

Users (myself included) asked that it default to incremental, which is how most users would want the centre wheel to be. 

As it was you needed to devote a button to switch to incremental and remember to do so every time the software started.

The outer wheel already does continuous why would you want the centre wheel to do so as well?

As to why the MPG screen is stuck on step mode and the step is stuck on 0.001,  I have no idea.  That is not normal and not how mine works.

You did not by any chance install the software that came with the Shuttle did you?  If so uninstall it.

To know what the step increment is, best to place the step DRO on the run screen.  Never understood why it should be hidden on a flyout screen.  (which I never use    )

Glad it is going for you now Whatda.

Think about putting those time delays back in won't you.

Well after you said that I raced out to the shed and tried it.

Apart from it having no delay (very quick) it worked fine on both macros.

I'm thinking you may have a dicky input.  Are you getting noise on it?

Have you tried the filtering in the SmoothStepper plugin?

There are a couple of videos.  Have a look at them.

Mostly you are going to learn more by poking around with it.

OK here it is.  You could write it in a couple of minutes.  It would be a good exercise to do. 

I repeat though there is no point having a brain at all if not wanting the timer.

It will all be simpler to do in the macropump with the exception of the switch delay.

Make sure with you trying different things that you don't get something wrong in "Ports and Pins"

Don't want two inputs on one pin or something like that.
