Title: Scan 3D in mach3
Post by: Ignacio Plass on July 19, 2011, 09:03:31 AM

Hello.
anyone know how to do this with Mach3.

tracking scan an object from the axis X or Y.

hook up your probe and run the digitize wizard

the answer is not valid.
 watch the video, wait 2 minutes of playback.
 really that scans from the axis X.
 moving along the X axis and Z axis ascending when it touches the workpiece.
 is not what makes the Mach3,

The Impact / Laser plugin that I use for laser engraving was developed from a Mach probing routine. The source code for this plugin is available from the plugin’s page and if you take a look at the code you will see that it is already two thirds of the way towards the probing routine shown in the video clip.
OK you would need to know a little C++ but it would not be rocket science for you to adapt this plugin to suit your own needs if you are determined enough.

Just a thought.

I actually went and watched the video and see what you meant.
I assume it only runs on their controller as a plug in software

Yep that is a NICE 3d probing routine.

Hello.
 I agree with you.
  but I want to know is:
 Mach3 can do?
 Has anyone done it?
 It is a good beginning to develop a plugin or routine scan, I do not know much about software.
this is my machine.

 I have changed the stepper motors for AC servo motors with encoders.
 fast scanning system is the only thing I'm missing.

Is this probing routine run inside Deskcnc?

no.
 works with an electronic circuit and a software called "colibri CNC" of the Italian company Twintec.

I would say that Stirlings Crawler method for probing would stand a chance or could be modified to do the job.

Happen to know the price of software and circuit?

Does the circuit control the drives and everything? Or piggybacked with Mach?

the main board it, 276 euros.
 the software is free and only works with the plate connected to USB.

Sounds good!

But, does main board control drives? Or does it work with Mach?

Hello.
 can not be controlled by Mach3.
 electrical circuit with the software generates pulses to control 6 axes. direction and speed, multiple inputs and outputs.
 I may buy the track, but I mounted the control panel to Mach3 and now will not work half the things the control panel.
 Mach3 is unfortunate that not scan this way,

Mach is capable of doing what you see "BUT" no one has programmed a plugin to do a scan like this. Art started a version to do it BUT retired before it was debugged.

Post by: Ignacio Plass on July 21, 2011, 02:20:06 AM

good.
 I'm glad that response.
 known if masters "Art" investigate, solve our problems,
 ;D "MACH3 live long." ;D
 as we push, the leading researchers in this field.
would be a good time to start a system scan but good for Mach3
 Thank you.

For 275 euros a shot I'd modify it to make the tea as well. Actually on second thoughts - make that GBPounds - euros arn't looking such a good bet...
