Re: Spring loaded engraving tool

Paul Kiedrowski
 

Those floating bits probably have a lot of runout due to the sliding mechanism. More for low-tolerance engraving work than PCB milling.
Plus the shank size is a lot higher than 1/8" so you need a bigger holder.
 
I myself never see a need for autolevel softare. With a decent machine table and PCB hold-down method you can easily stay within a few mils flatness.
Using endmills instead of pointed tools allows for enough Z variation to keep it under control.
With a 62mil PCB, I set depth to 8-10 mils and that allows for up to about +/- 6 mils of non-flatness.
Of course with larger boards it may be more difficult, most of my work is less than 4 x 4 inches.
 
The original T-Tech PCB machines and others used the spring-mounted foot method for depth control.
It works very well, and they used just a solenoid for Z up/down, not a stepper/ballscrew.
The whole Z spindle rides on the PCB (cut depth is of course settable).
The nice thing is you don't have to even calibrate for Z=0, the head just drops and its good to go.

Unfortunately that line is no longer being developed.

However, JJ (author of pcb-gcode) is developing his version but at this time is not ready for release.

Ivan de Jesus has his stand alone version and can be found at:
https://github.com/ideras/pcb-probe

daedelus has a version that is available and the latest uses a stand alone probing file which will allow restarting without re-probing in case of a needed tool change and can be found at:

http://www.autoleveller.co.uk/

Also in answer to your original question, there may have been a spindle speed entry that needed to be filled in. Even if you do not have automatic spindle control, by putting a value in there is should work. (Going strictly from memory here)

Actually I had this one before I downloaded v3.5.2.11 is because it had a setting for height probing. Is there any other way I can height probe my pcb from inside eagle (using mach3 of course) ?

Alex,
Might I suggest that you download V3.6.2.4 as it has several updates.
It can be found here:

Why bother?!


I have autolevel integrated in EMC2. It should be possible do something similar in MACH3
or whatever you use.




tried it.


never again.

Re: Autoleveler on tb6560

The Guy Train 1
 

I want to say thanks guys for all your help. I finally made it. The cnc is using autorleveler prog. It took me a wild to figure out what was the problem but I finally found it. It was the side of the x and y axis bed size and the z axis. That is why in the video you can see the height is too hieght. 
 
Thx guy 
Excuse me English.

Hi Dylan,

 

Is either of the motors “growling” at some stage of its operation instead of making a nice even tone when it moves? You may have a mechanical problem due to some drag somewhere.

I ran a test with a simple circle and I found out that I get an oval... I think there's a problem on the Y-axis since the circle is somethings milled as a circle and sometimes as an oval.

So it isn't the software... I must be my CNC and that's something I don't understand since it worked last time I used it.

Re: Autoleveler on tb6560

Maybe my probe setup guide will help: CNC Probe Guide - Autoleveller

 

In LinuxCNC, use the hal meter as described to safely check the probe is working.


Re: Autoleveler on tb6560

Dan Andersson
 

You need to change the basic autoleveller settings to fit YOUR mill.


All mills are different depending on maker and type.


Use a slow plunge when probing. Some very slow computers are bad on realtime and that will make the stop time vary with a varying depth correction result.

No,


Use one axis only, like "G38.2 Z12 F3"


F3 is the plunge speed and you want to go slow first times so you don't kill the tool holder.


My Lumenlab M3 mill will justabout totally wreck the PCB and the vacuum board if the probe doesn't
get the cutoff signal.
