My Laser Scanner DIY Setup

From a week i am working to improve my David Laser scanner setup.. Earlier, I have a stepper motor attached to 1:60 gear box..The output was very coarse with jerks so yesterday i made MDF bearing holders and grabbed teeth Belt and Pulleys from local market..After minor modification the output from the gear box further reduced to 1:7 with timing belt..Now i can scan with very high resolution..Attached is the low resolution scan from free version of David Laser scanner..Its smoothness and interpolation kept to one..You can see how small the object with details...
The green laser pointer was gifted by my friend Richard..i made a teflon attachment with a lens to convert it into Line laser...

This improvement of setup was carried out because i want to make some ball-claw legs for the table i am machining.. The idea was to take the leg of hen and insert a marble ball into claw and scan...

Bear Jewelery Box

Sometime its good to gift something special to wife... This time i decided to make something very special to her, a Jewelery Box... What about the jewellery box in shape of a Bear?...!!!.. Yes, a lot of girls and ladies like Bears.. I don't know why?..

When i finsished this on my CNC machine and gifted to her... She was really very happy ... Now i can continue some other projects on my CNC machine ;)

My Head Post

Frankly speaking what fascinate me to make a indexer for my machine??... This story begins with the day when i joined CNCzone Forum... One of the guy their working on its 4th axis created a BEAR head on wood...He posted the picture of machined head stand aside with its computer monitor... and that was the really great work i ever seen.. i downloaded that picture and saw it many time that day...
At that time i was very new to CNC machine.. i never built my CNC machine at that time..i was just collecting the pictures, ideas and reading the posts of zone members... its a really great website for all of us with zeal of working with CNC....





The complete time for Roughing 13 Minutes and Finishing pass took 1 Hr and 13Minutes...The stepover and tolerance were kept high so the quality was not come out great.. but this is in my hand.. The main was i know how to create efficient 4th axis toolpath..

If i decrease the stepover and tolerance values..you will see the quality, details and real beauty of it..
