Mach3 and G-Rex / G100 problem with 2 motors on Y axis
« on: July 06, 2009, 04:00:16 AM »
I have a portal milling machine with Y axis driven by two step motors on each side. If i call it home, or jog manualy, all works ok. Both motors run.
Problem starts when i run any gcode part program, then only one of motors moves, second one stays motionless

Hope you understand, my english is poor



General Mach Discussion / New version of probing plugin
« on: December 09, 2008, 12:19:34 PM »
Hello Everybody
I have downloaded new version of probing plugin from artofcnc.ca. I use tool for finding center of the hole only. I used some previous version of this, without any problem. I had to reinstall mach3, because of change of my computer.
But new version does not work. Probe touches 4 points inside the circle. Last one is in -Y direction. Then it should go to the center of the hole, but it continues in -Y direction. If I would use it seriously, not just for test, my probe would be broken.
Do you have any idea? Or do you have some older version of this plugin?

Thanks for any help

I have solved the problem with finding of hole center. When i increased speed of my TP 100 probe, it started to work ok.

But i still do not know the right procedure for 3points functions.

Hi all
I tried this plugin and probe object function has worked ok, but finding center of  hole usually stops when probe hits the edge of hole. It is not always first hit, but i have only 50% chance to finish complete "hole scan". When i try other function with three points, i  make  touch in all 3 points, each is confirmed by point recorded statement in mach, but when  i try center or rotate 3points function, mach asks for points recording again. I do that again, but all repeats. 

Thanks for any help

Hello Nick
I have used same sources for my simple macros. Does your macro work when you made rotation of coordinates?
If yes, how much for that? :-) It can save much time to me.

Hi all
I have made modification of some auto tool zero macro and it works as i wanted. Now i have buttons for probing in each directions, but i have tried Brian's rotation set wizard and i found new problem. First i made rotation of coordinate system and then i touched material in X and Y direction for finding of zero point,
till here each move was done in right direction as coordinates were rotated, but when i hit goto z button i found that it does not work as i expected, because zero point was taken as without rotation of coordinates. Sorry if you do not understand what i am trying to say. Hope that picture will help


Any ideas?

I fully agree with you, but i hope that someone here can recommend me some macro or wizard for probing in x,y directions.

If anyone wants to see my machine, follow this link http://aluminiumracing.com/arttechno/art6090-1.jpg
Yes, it came from china, but works perfect after complete reassembling. They used good parts, but the quality of assembling was terrible.

Jim, you would not believe how long i tried to explain it to man who is interested in my cnc. I know it is the easiest way and i use it, but he saw similar system somewhere and just requires that.
I have sold few machines before and i have a lot of experiences with guys who necessary need 0,0001 accuracy of cnc, but then use material with +/- 0.5mm tolerance.
This man should be same so i have to make something more sophisticated.

Hi Bob
Thanks for your response.
I was thinking about something like auto tool zero for z axis. I am using mobile calibrator and i guess that i can make new button for each axis and implement some macro to them. Macros should be similar to auto tool zero macro. Thats only my vision. If you tell me that is necessary to use probe, i will do that. But digitizing wizard which i have found looks too complicated to me. As i wrote i need only to touch semi finished product from each side for accurate zeroing.

I will try to find that mechanical edge finder on ebay. I have never seen something like that.
Thanks for another good tip.
