Pc Dro

[h_2_o]

i was looking around for thermocouple devices and came across my favorite interface site on the net, phidgets.com (not a plug i just love that place) anyway they have high speed encoder interfaces now, i was thinking for $160 plus encoders you could have a nice pc dro system setup

link to high speed encoder interface

http://www.phidgets.com/index.php?mo...11.146&IID=119
encoders supported are
grayhill
usdigital
avagotech
cui

looks like it might be a very nice solution for some of us. anyway i'm not sure i'm going to do a dro like this yet but it is an option i thought of and thought i'd share

I looked at those (high speed encoder), a while back.

I bought a 0/0/4 kit, from another supplier http://www.trossenrobotics.com/store...Kit-0-0-4.aspx
$6.00 cheaper, & very fast delivery!

Phidgets are very easy to program with the free "Visual Basic 2005 Express" http://msdn.microsoft.com/vstudio/express/vb/

I might try the high speed encoder, later on.

The only thing I didn't like is the phidgets forum (not very active).

i've worked with phidgets before too, i have a couple of their rc servo controllers (which i believe some day could actually run a mill but are being used for other things currently) anyway i agree their forums stink but they do provide nice examples to go off of. I might seriously have to look into this as a seperate DRO system because it looks like it could be cheaper than others out there currently plus if you put the encoders right on the shaft instead of looking at the servo encoders you would never miss steps.


btw i linked directly to phidgets site in ca instead of the reseller in the us. that link you posted is the company i've bought my stuff from as well.

Hi,

I built a machine with the intent of controlling it using the phidgets 4-motor controller, the problem is I don't know VB.NET and need to make stepper motor "0" the "X" axis and stepper motor "1" the "Y" axis.

SO I suppose my question is how do I define each stepper a Axis? Or even single out each Motor using VB.NET, I only need two axis and I don't expect the steppers to work in sequence.

Hope someone can help.
