General Mach Discussion / Re: Mach3 and mill set up

Alan,
 I have setup 6 VMC's so far and all of them I consider the tool moving.  There has been no regrets or problems in the brain (on that issue!) but when I purchased a new Johnford VMC it was all in relation to the table movement! Thanks a lot Fanuc for the confusion!

Mach3 and G-Rex / Reading Inputs

« on: March 14, 2006, 11:43:00 AM »

There seems to be a little snaffoo with reading inputs.  My home inputs work fine for all six axis I'm using, but this code hangs:

     Code "g91g00 z-.52"
     SystemWaitFor(18)
     Code "g04 p2."
     Code "g91g00 z.5"   

signal 18 is for Input 1 which shows on the screen just fine, but when I try to trigger something by it, it does nothing.  I've tried  reversing the "Active Low" check with no difference in results.  Maybe this isn't functional yet? Let me know, and I can work around it.   

#2
I'm homing only X,Y,B,C.  The X and Y automatically ZERO, while the B and C don't, in fact won't.  When I try to change the DRO for the B and C, it reverts back to the previous numbers when I ENTER.  The only way I can get those two axis to cooperate is to exit the program then restart.  At this point it will allow me to change the #'s to ZERO.  Any Ideas?

General Mach Discussion / Re: Grex and Mach4

Brian,

 I'm not quite sure what would constitute a ton, but here is what I do need:

6 step and direction outputs
5 of which need to have feedback (as I understand Grex will)
1 motor speed control
1 coolant
4 aux output
4 aux input
4 home switches

I wasn't sure how the plc would handle the real time step and direction speed... yada yada

I would like to seed what plc your refering to though if you think it will work.  I think the glitch will be the feed back on the encoders.  Does that seem right?  If worse comes to worse I would have to have at least 2 of the axis with feedback.  Maybe use servos on just the two?

PS
   I have a 800-441-2973 if it would expedite things

Thanks for the reply, Brian.  Could you recommend the MC-01? What about the feedback of encoders on the steppers, and can I connect multiple modio's to get more IO?

General Mach Discussion / Grex and Mach4

« on: January 21, 2006, 12:45:20 PM »

I really need the quantity of IO that Grex or another modbus can
give. I also need the feedback from encoders, but would like to try
steppers with feedback. I already have the steppers with encoders
ordered (5-34 frame and 3-23 frame, one spare of each). Is the mach4
operable enough with the Grex to actually run a machine? As far as
safety issues, My machine travel is approx. 1" by 2" with a feed rate
of approx. 10 ipm or less and the entire setup totally enclosed. I
understand that the "end user" version of G100 is the same as the G101
+ G102, but do I need to wait for the software to possible become more
stable, therefore no hury since the G100 isn't actually shipping yet?
(No disrespect or digs intended)

anxiously waiting,

T. Byrd
