General Mach Discussion / Mach3 to replace Fanuc

« on: July 09, 2009, 08:59:28 AM »

Hello.

I lost my head and bought 3 big industrial machines with 10 years old for a good price, they have worked for 6 years. All have fanuc motors, amplifiers, spindle controllers and so on. One have fanuc 21i-t and the others 18i-t. I have power on the machines and the servo amplifiers went to a ready state and the controller also seams to be working fine, but now I started to clean the machines and will probably simplify the machines. Since I am confortable with mach3, and not with the fanuc controllers, I am thinking in replacing the fanuc controller with mach3 in case that I will have problems in putting the machines to work (something broken or impossible for me to putting it to work).
It is a straight approach to use all the fanuc present in the machine exept the controller?
Motors and amplifiers are ok, so I would only replace the controller. Is this possible and recommended ?

Thank you all.

For a easy to use, stable dxf to gcode plasma application, please visit:

I am not quite sure if this is in direct competition with lazycam, but if it is it will soon be removed, or let me know, that I will remove myself.

Brains Development / Kernel speed and brain speed

« on: June 16, 2009, 05:53:58 AM »

Hello.

Just want to know if the brain speed (number of times / time unit it is run) is in relation to the kernel speed.
I need a sensor to stop an axis, and the axis stops in a random position due to the fact that the brain does not process the input signal at the same time after the signal is high.

Thanks

General Mach Discussion / Mach 3.042.021 bug in turn

« on: April 16, 2009, 07:18:02 AM »

Hello.

I am running turn for quite some time. During a cycle, were I used frequently start and stop buttons for checking accuracy of the part being made, I lost the toolpath window (stop seeing the toolpath). I have stoped the machine, exited mach and load it again. Result: white screen (like no screen was selected) and no information about the configuration - the xml file was totally reseted. I add to load an old xml, from the backup directory.

Any ideas of what could happen? This is a new bug?

Thank you

General Mach Discussion / Input = high if user is pressing key

« on: April 11, 2009, 04:15:07 AM »

Hi there.

I know how to turn on an input using a keyboard key and emulation under the config/ports and pins. This works, and when I press that key the input goes hi, press it again goes low.

My objective still different form that scenario: is to have the input hi during the time the user is pressing the key. If the user stops pressing the key it should go straight to low.

Is this possible?
Thank you.

General Mach Discussion / Unwanted softlimit behaviour

« on: October 27, 2008, 04:53:07 AM »

Machine: Lathe with X and Z with homing and limits; A axis without limits or homing (rotational axis)

Having the softlimits on, I always have a warning before running a part - a softlimits warning. It is related with the lack of a softlimit in the A axis, because the instant I remove the a axis (on the config ports and pins), the warning does not appear anymore.
There is any way that mach only will take care of the axis limits that the user chooses? Because I do not have, and do not need a homing in the A axis, but I need the homing in the X and Z.

Thank you

General Mach Discussion / Optional stop in screen

« on: October 15, 2008, 01:56:54 PM »

Gentlemen,

It is possible to have an optional stop on/off on the screen, instead of going to general config ?
Sometimes I need to stop the gcode file, others don't - for the same code (depends of the number of chips). In this way, the user can switch on/off during a program execution. Feedhold is a little bit scarry, and I had before ruined parts because of feedhold.
(Or can this be done in a different way ?)

Thank you

General Mach Discussion / Tool offset / tool slot

« on: October 08, 2008, 06:32:54 AM »

Hello.

In turn mode, if I am using 2 tools on one slot (slot nº1 for example), I can call them as:

T (toolslot) (tooloffset)

T101 (this will load offset 1)
T102 (this will load offset 2)


The X and Z offsets are working on the DROs, but the tooltip information and tooltip radius information displayed on the mach toolpath or in any DRO that points out to the current will only point out to tool number 1 with offset nº1.
I think that mach looks for the toolslot insted of the tool offset.

Can anybody confirm this? It is a bug?

VB and the development of wizards / Spindle led

« on: October 03, 2008, 04:37:28 AM »

Hello. I would like to turn on a user led when my spindle is on, then turn off the spindle, but I still want that the led remain ON, so I did:

If GetOEMLed (11) SetUserLed (1500,1) ' This is ok, will turn on the user led 1500
If GetOEMLed (11) DoOEMButton (110)' This turns off the spindle, BUT also turns off the led 1500

This should not happen. What I am doing wrong ?
Thank you,
Filipe

VB and the development of wizards / Running a system function from VB

« on: October 02, 2008, 06:56:22 AM »

Hello.

There is a system function that is: Home X

I want, in a button that does several other things with VB to call that system function.
Right now, I need to press two buttons. One with the system call and the other with the rest of the VB stuff. It should be all done with one button.
How can I do that ?

Thank you
