Re: [Emc-users] Absolute Encoder Feature Request

2010-03-09 Thread Leslie Newell
The way I got around this problem is to use the hal_input component with 
a USB game port adapter such as this one 
http://cgi.ebay.com/15-Pin-GamePort-to-USB-Port-Adapter-for-Flight-Joystick_W0QQitemZ310199439311QQcmdZViewItemQQptZVideo_Games_Accessories?hash=item483953cfcf.
 
These ones 
http://cgi.ebay.com/USB-to-15-Pin-Joystick-Gameport-Converter-Adaptor-Cable_W0QQitemZ260550295897QQcmdZViewItemQQptZUK_Computing_ComputerComponents_JoysticksJoypadsGamepads?hash=item3caa020159
 
don't work very well.

These adapters work with the absolute position of a potentiometer so 
there are no problems with losing position after a shutdown. It is also 
much cheaper than using encoders. If you want you can use a hacked 
joystick but the adapter is more tidy. I did find that they are a bit 
sensitive to EMI so it is best to keep them well away from power wiring.

I know this goes against the EMC way of doing things but who is going to 
want to use a GUI based override when you have a nice convenient knob on 
the front panel? I use this for feed override, spindle override and 
rapid override.

 Thanks to some help from the IRC (tom3p), I got the encoder working with
 AXIS's spindle override. One problem I am still having is that when AXIS
 starts, the spindle override always starts at 100% even though the knob
 is usually at a different setting. When I move the knob, the override
 moves proportionally with the knob until I hit the 0 to 1024 encoder
 boundary. After this the knob and the slider agree. Is there a way to
 have AXIS start with the knob setting?

[Emc-users] AMT-102 line driver and Mesa 7I43/7I42

2010-03-09 Thread Tom Easterday
I am rebuilding an older small mill and am using stepper motors and adding 
AMT102 encoders for feedback to EMC.  Without thinking I bought the line driver 
cables for the AMT102.  Can these be connected to the 7I42?  I don't fully 
understand what signal I will get on X', X, A', A, B', B and if the voltages 
and bandwidth are sufficient on the 7I42 card.  Is there a different daughter 
card I should use with my 7I43 instead?
Thanks,
Tom

 The NIST/EMC way of doing things doesn't just apply to pendant controls
 vs GUI controls.  It is a general principle for any time there can be
 more than one source of control.

 It will be at least a few days before I get a chance, but if nobody

In my case, I only used an absolute encoder because I had an absolute
encoder solution looking for a problem. Since incremental encoders are
generally less expensive and easier to implement, it seems logical to
use an incremental for the overrides.

What would be nice though, is to have access to the master inputs, so
that one could choose where the master encoder is placed, AXIS or
physical master console. The slaves could be other consoles, AXIS or
pyVCP.

I wonder if the halui components should have the s32 inputs, the clock
up/down inputs are more appropriate. A separate absolute to incremental
encoder component would make it clear how a halui slave is supposed to
work. my2c

I have to say that pretty much every machine I have ever worked on (I do 
quite a bit of repair work) that had an override used a pot, giving an 
absolute position. I don't think I have seen one with an incremental 
control for the overrides.

EMC2 does it the same way. It's just a virtual pot in AXIS, which gets
set to 100% when AXIS starts. On other machines, you get the same sorts
of problems when one wants more than one master control. They really
need to be slaves.

Thanks. A brief scan seems to indicate it is like the simple trajectory
explained in the wiki. Now where did I put my thinking cap.

[Emc-users] USB cionnection

2010-03-09 Thread Paul Midgley
Hello

Thanks to the people who responded to my post.

The reason I asked the question is that the Reprap project at 
www.reprap.org, do exactly what I suggested. Unfortunately their project 
is making items from plastic in a 3D prototyping machine that you can build.

Although I would have a go at programming it myself I am not clever 
enough to carry out such programming, which is why I was hoping someone 
else had done so.

Thanks again

Paul

The 7I42 only has single ended inputs so you can either use the 7I42 and only 
connect the A,B,X signals (this would mean you would not gain the noise 
immunity of the differential encoder outputs), or you could use a differential 
interface card like the 7I47. Since you already have a 7I42, I guess you might 
as well try it and only upgrade to a 7I47 if noise on the encoders is a 
problem.
