General Mach Discussion / Re: Help with servos and drives.

« on: January 22, 2010, 07:11:42 PM »

I pulled apart some Mitsubishi servos that looked as though the had gone bad due to bearing failure. I've got 5 or 6 of them so I'll look into what type of encoders are on them.  Good advice to find encoders on smaller less expensive motors!

Thanks again,

Starting to make sense to me..

Here's a pic showing the pin assignment for the motor.

Maybe you can tell me what pins on the motor go to what pins on the drive?

Thanks again for your help here!

Thanks so much!

I've got  Centurion micro DSA drives.  I've got a collection of various motors and will get others if needed.  I've got some Mitsubishi AC servo motors and also some Aerotech brushless DC servo motors.

Not sure what is compatible with the G&L drives..

OK, I'm comfortable with steppers having built a half dozen machines but now want to make the leap to Servos.  I'm building a large gantry mill (6' X 10').

I've got a couple of G&L centurion drives and some Aerotech BA series drives as well.  I've got pinout diagrams and manuals for the drives but just don't know where to start.

I'm pretty much clueless as how to interface the drives with mach

Any basic help would be much appreciated!

VB and the development of wizards / What do I need to edit the scanning wizard??

« on: December 17, 2009, 10:04:34 PM »

I'm working on several new probes including a laser non-touch probe what works quite well with the wizards in Mach.

I'd like to customize the parameters of the wizard.

What do I need?

I've never done software development before but am good with machine language and a quick study.

Thanks in advance and here's a couple of pics of the laser non-touch in action..

General Mach Discussion / Re: G31 scanning slow z speed?

« on: December 08, 2009, 08:02:40 PM »

Do you have a feedrate command in your probing code?

I don't but was able to basically add in an F300 one line then a F100 a line or two down with a word processor and that does the trick.

Just wondering if there is a way to tell mach to run the z axis at a given speed during a G 31?

General Mach Discussion / G31 scanning slow z speed?

« on: December 08, 2009, 03:41:49 PM »

I'm using mach 2 (have mach III too) do digitize with a high speed probe I built.

Anybody know how to get the mach to pick up the speed of the z axis during a G31 op?

Looks like mach really slows down the z axis during a scan, (it's only slow on the way down, z axis runs full bore on the way back up to zero)

Any ideas?

Thanks

Video P*r*o*b*i*n*g / g code from touch probe?

« on: November 30, 2009, 05:04:52 PM »

It was suggested that I pose this question here on the video probing forum even though I'm using a touch probe..

Thanks!

I'm looking for a way to edit the code generated by the digitizing wizard (not plug-in) to a more usable format.  The file Mach generates is missing the x, y and z characters and simply separates the coordinates with a comma.

I could generate a point cloud in my cad program if the code was simply edited to include the X, Y and Z letters in each line..

Here's an example

Here's what I have to start with from Mach

-6.032136,1.419120,0.835333
-5.907102,1.419120,0.822000
-5.782069,1.419120,0.803333
-5.657035,1.419120,0.776000


This is what it needs to end up as so my cad/cam can read it.

X-6.032136,Y1.419120,Z0.835333
etc..

Any suggestions?
