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,

It is going to be a bit before this is ready to run a machine.. I will be getting one to start testing in a few weeks and I will post on the forum after I get it running.

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?

If you are looking for a TON of IO I think you are going to need to look into a PLC... I can show you where you can get about 64 in and out :)

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?

Sounds like you are going to have to hold out for the GRex :(

To bad you need to have the feedback...
