T2 Engraving / T2 CNC surface scanning / auto leveling / Edge scan?
« on: March 15, 2018, 03:45:15 AM »
Hi Zax

It could be great if your T2Laser software could surface scan  :)

and maybe edge scan

Z Axis / Re: Banggood Eleks Z Axis Kit - any issues?
« on: March 15, 2018, 02:30:02 AM »
Actually I have this z-axis and it works fine on my A3 EleksLaser , yes there are some weight but when using the motor and drill it is only good.

I all so use it with med Laser + pen drawing and it works great :)

The only minus is that your working areal decrease on the y-axis, but I have now ordred new aluminium profiles so I can extent the length of the y-axis

I played with glass most of last summer. Wine bottles are hard

You can see my attempts/failure/successes here http://benboxlaser.us/index.php/topic,2118.0.html

Nice, I may try out this with my 2500mv laser with a black card behind the glass

I have been laser etching wine glasses and currently do not have a z-axis. Limited to a relatively flat (vertical) region of the glass. Ready to add the z. Have stated on a software solution where I store various glass profiles and select at etch time. Would prefer a non-contact distance sensor and let the application do the figuring.

BTW - I suspect the laser is much more forgiving than a cutting tool. Do you do multiple passes?

HI

Yes I do multiply passing , setting it to about 8 passes 3mm just to divide up, then when I think it looks okay I stop the cutting.
For this example it only had 3 passes.

I would all so like to make my ovn distance sensor so I can level out the curves there are in the bottle.

It could be nice if T2Laser could read a surface profile in x,y,z and do the math in that case we would be able to drill on every surfaces  :)

A surface profile scan would only require that it reads the z- distance censor in a x,y resolution by 1x1cm grid (maybe less 0,5x0,5cm grid)

Thinking about it
I total forgot to set the bottle size in my T2Laser setup

But it came out okay
Pure luck I think

Thanks for the comments
A wine bottle is not at plain smooth surface so I will se if I can trace the surface and adjust the z axes while the job is running

Have someone tried this ?

Projects / Rotary engraving in glas with diamond drill bit
« on: March 12, 2018, 03:41:36 PM »
Hi Here is my first try , engraving a bottle with my rotary diamond drill bit.

It works first time, pouring few drops of water now and then

3 passes with a speed of 500 (full speed on the motor)

The connection bit hole to my motor is 3.1 , but my diamond drill is only 2.9 so is was a little shaky 

Using T2Laser from Zax everything works just fine  :)

Hi

I found this driver

https://www.banggood.com/TB6600-4A-CNC-32-Segments-42V-425786-Stepper-Motor-Driver-Controller-p-1093437.html?rmmds=search&cur_warehouse=CN

Now I just need to find a good power supply
Do you know a good one in banggood?

Hi Raimund

Yes that will be great, if you can make an diagram and upload it here, then everyone can make use of it  :)

I will come back with my choice

Hi thanks for feed back

Maybe is it a bit overkilled with a DM442 for my use, a smaller bridge solution could be the answer

Hi Raimund

Thanks for the feed back. I will see hove it goes and if the driver gets to hot I will put a Fan and heatsink on.

If you have A link to the driver you are using, please feel free to post it here, that will be nice.

by the way that must be external right?
