I have seen this page before and my reaction is the same every time I see it- Sheer astonishment.
 I can't even imagine the amount of time and effort that took.
And to add insult to injury he is drawing the parts in acad 2000 ( 2d) and printing out the dimensions and hand entering them into his controller. Yuck. Imagine what he could do with solid works and master cam...

Cool thanks Brian.


General Mach Discussion / ART! Can i buy a licence for mach 4?

I know 4 is going to disappear soon but until then I need to go over 1000 lines for a project that has to get done before next weekend. I have the grex built into my knee mill and it would be a pain in the butt to retro it to Mach3.


Mach3 and G-Rex / Mach 3 Grex plugin

( Hi all, Art didn't cross post the latest info on the Mach 3 grex plugin here so I will do it for him. If you have a rex please post any comments for him. )

Hi All G100 owners. :)

Verison 1.90.051 is online as is the first Test PlugIn for the G100.

To test your G100 functionallity in terms of IO, just copy the G100.dll to the plugins folder in your Mach3 installation. You must be using .051 version to test the G100.

Id be interested in any feedback on how easy it is , or how difficult it is to get running, I have puposfully
made no instructions on installing or getting this plugin running. The program should guide you sufficiently.

Remember, to configure any plugin, including a G100, you select operator/Config plugins..

That knowledge shoudl be all thats required. You wont get movement on this plugin of any type, but all IO
is functional, and connection to the G100 should be immediate, and with no errors unless your G100's
address is wrong. The program will prompt you if this is the case and allow you to correct the trouble. It will also recognise if the firmware in the G100 is not running. Eventually, it will be able to start the firmware in the G100 on its own.

Anyone who feels they can understand the C++ code for this plugin,or are devloping their own External device just send me a letter offline, and I will send you a copy of the plugin project. It is open source as of now. Eventually, Ill post it on the support website.

The new plugin release is on the downloads page directly under the 1.90.051 download.

Good luck, let me know what bugs you find in its operation, it seems to be very stable so far, but Im sure someone out there can find what Ive missed, you guys are good at that. :).

Next functional add-in to this code will be Jogging. Hopefully by next week, then GCode movement. Then homing and probing and we're pretty much done till the next firmware is offcially released. Soem recoding will then be necessary.


No problem, happy to help.

I am learning as i go too..

HI, What do I need configure to tell mach 4 to use the 0-5 analog out?

Sorry yet another question. I have a vfd (wthout encoder) and and it can accept prettty much any input. What is the best way for me to implement it with the g rex? Are the analog outputs working yet?

Sorry for all the questions but documentation is a little scarse on this thing, And i can't just call up art and bug him ;)

OOPS forgot:

Art, When can i send you some money. I would like to get over the 1k gcode limit and start making some stuff.

Hey Brian/art

 Just got my knee retro going last night and WOW!!

I have already noticed some funkyness with the grex and mach 4. I understand it is still in alpha and am looking forward to the new plug arcatcure and the g100 rewrite.

My plan for today is to get the limits and home switch wiring up and running and was wondering if it is even supported in the current release. With the speeds and power i have going i really want some kind of safety on this machine. If they arn't going on the grex side then i will probably wire them directly to the servo controllers as a "STOP"  just for a little protection from a runaway grex.

Art: so far thing are looking Great!! keep up the good work. I would be happy to ship you a case of beer if that that would help the plug in work go a little faster! ;)
Another question, do the encoder inputs to the grex work yet? If so what pins should i use? My drives have encoder outputs and I would like to hook them up for a dro in manual mode..

Brian: I basically did what you did to your mill. I am using Baldor microflex drives and 1.1 kw ac servos. WOW. I guess the old adage is true. You get what you pay for.




his leads me to beleive that somehow I have something hooked up wrong with my Limit switches.  Currently my E-stop button is inline with my limit switches and I am thinking this is my problem.

Yep that is your problem. The estop should be all by itself. I bet you have the e-stop pin checked in your ports and pins and set to the same pin as you limits (think about what that is trying to do in the program). If you change the pin in the ports and pins and remove it from the limit loop it will work correct. Don't forget to change the active low or active high on the new e-stop pn.

For a quick test try just disabling the estop in ports and pins.
