General Mach Discussion / Galil - from art
« on: July 22, 2007, 01:48:20 PM »
Hi Guys:

We just heard from Galil they have done a white paper on Mach3's usage with Galil controllers.
We will announce a location for it when they post it. Its a big step to get accepted to that level by Galil,
so hats off to Brian for all the hard work in the connection to Galil controllers..


Tangent Corner / Stumbled on this today thought it was funny
« on: July 06, 2007, 07:12:30 PM »

I have 2 dogs & I was buying a large bag of Pal at Big W and standing inline at the check out.

A woman behind me asked if I had a dog.

On impulse, I told her that no, I was starting The Pal Diet again although I probably shouldn't because I'd ended up in the hospital last time, but that I'd lost 50 pounds before I awakened in an intensive care ward with tubes coming out of most of my orifices and IV's in both arms.

I told her that it was essentially a perfect diet and that the way that it works is to load your pants pockets with Pal nuggets and simply eat one or two every time you feel hungry & that the food is nutritionally complete so I was going to try it again.

I have to mention here that practically everyone in the line was by now enthralled with my story, particularly a guy who was behind her.

Horrified, she asked if I'd ended up in the hospital in that condition because I had been poisoned. I told her no; it was because I'd been sitting in the street licking my balls and a car hit me.

I thought one guy was going to have a heart attack he was laughing so hard as he staggered out the door.

Stupid bitch...why else would I buy dog food??


General Mach Discussion / Update post from Art
« on: July 06, 2007, 05:50:17 PM »
Hi All:

Version 2.01 is online and is the new lockdown (Mach3 Suite). It incorporates all bug fixes to date, add the tool length comp to the
toolpath display and has the new lazycam . It also has a new Mach3 flash screen which can be loaded
from the /Flash folder. Flash screens may now be stretched to any size, with the full screen being used.
Oh, and I more than doubled Mach3's speed since we're near done with the printer driver.

You may now select 25K, 35K, 45K, 60K, 65K, 75K or 100Khz as your base frequencies. A few notes..

This does not mean you should be the "cool" guy and use 100khz because you can. :) , remember at all times the rule,
if your velocity slider is maxed out in one kernal and you know you can go faster, then you may bump to the next level. It
takes a fair amount of cpu to run 100khz. My 1.2Ghz single core just manages it. Remember that windows slows as mach3
increases in kernal speed, so keeping it as low as possible makes the gui work better and such. I wont have much
sympathy for the guy reporting jitter or lost steps at 100khz when switching window screens. Specially if his motor maxes
out at 8khz. Keep the kernal as low as you need, but if you need 100khz, then fine, go fer it. It seems to work here fine
and even 200khz was pretty stable for me. ( And no, I wont send you a 200khz version, youll just have to trust me. :-) )

That having been said, over the last 2 years, CPU's have sped up, not to moores law's dictates, but quite a bit. Those with
dual core cpu's and such deserve to get as much as they can, so in thet vein I have increased mach3 to 100khz.
For those curious about such things, I have run successfully at 230khz, but barely, any my computer locks up at 300khz output,
the theoretical limit is about 333Khz with no pulse stretching, but I doubt Ill ever see it. I have locked it to 100khz
because I like to have it half the speed I can run, thus meaning most could run at that speed if they had to. Expect a 4 second
frequency lock in time at very high kernal frequencies when starting the program.

The new download is 20megs approx. My appologies for that, but Mach3 has grown quite a bit over time, so this lockdown
was bound to be much larger than Mach2. However, I am moving to an update system that will only contain the files needed,
and will then make updateing much faster. This means in future that updates may only be made to a system already running the
latest lockdown version. The lockdown version will rarely change. It is quite stable, and will be only periodically updated to
take into accoutn the files that will appear in the development update installer. I have only a couple minor bugs Im chasing
in areas most dont use.

Have fun, experiences at higher speeds are welcome, Id like to know how the higher kernals affect you, dont blame me for
having to reboot if you push for the moon.. Id recommend a 1.3Ghz fast machien for 100khz, and thats a dead minimum...


Sorry for all the posts, spent the afternoon organizing pictures.

These are of a paddle shifter and display mount that was made on our converted knee mill running mach..


These were cast from molds that we made on our big mill powered by mach..


Newfangled Solutions Mach3 Wizards / Ron, idea for a new wizzard.

HI, I have been asking art for these for a while but I know he has other pressing things to do, not that you don't but....

All of these involving probing. And all could be part of the same set.

1- datum points. A work 0,0,0 routine. In other words the ability to choose one of the four corners to set 0,0,0 or calculate the centers of x or y or both. it would be nice if you could just jog and bump into edges. A routine to find the center of a hole or round boss. 

2- Reverse engineering. The ability to probe features (2.5d) It would be nice if you could have this also to store concordances to a text file for basic cmm operations.

3- work rotation offset. It would be really nice if you could just touch off on two edges of say a vice and have mach set the angular offset.

You would have to add the probe diameter

Any way, just something for yo to bang out if you get an hour or two :)


I was noticing that as of this writing we have 2795 members and have only heard from a couple of hundred and an even smaller number of regular posters.

So if you are new around here please post and introduce your self.  You could give a little on your background, hobbies , how you ended up here, whatever!

This is a site to help with mach. There is a great talent pool here already but this is a community driven site and we would love to hear from the silent masses ;)

So stand up and say hi!!



Mach3 and G-Rex / Mach 3 Plug-in and Grex Current status.
« on: January 18, 2007, 05:27:45 PM »
I am going to lock and sticky this post as a place Just for the latest on Mach3 and The g100 plug-in.

Mach3 plug in: The plugin is in a beta stage and is for the most part functional. Most mach functions are implemented, but not all.

Grex hardware: The hardware is finalized and a shipping product.

Grex Firmware: The current version of firmware is for the most part functional. There are some things that are being added and debugged before a official release expected some time in 2/07 (last I heard). The firmware is being written by a third party. In other words Not ArtSoft and not Gecko. This Person is named Steve and he has don amazing things and it is no small task. he is working as fast as he can and we will just have to be patient.

Things that Mach3+Grex will NOT do at this time until the new firmware is released:

   Spindle sensing- ridgid tapping- threading.
   MPG Inputs. ( I believe art has one enabled for test but don't take my word on that)
   Soft limits
   Backlash correction
I have seen, and have have heard of others having problems with the Grex randomly stopping during a job- so be careful.

Mach 4 is no longer supported or updated. It has been replaced with the latest version of Mach 3 and the Grex (or g100) Plug in.
Mach Quantum Does not at present work with the Grex. This will come later. Mach Quantum is still a test bed for some new features that Artsoft wants to experiment with. It is not a production stable release and should be treated with care. 

That is all I have for now as I Hear more I will update this thread.

Here are a couple of pictures around my apartment. There are some pics of my friends Humvee. He was out all day and night pulling people out of snow banks.
