Title: Resin dispensing machine
Post by: Romanr9999 on September 06, 2009, 09:12:04 PM
Hello all.
I´m quite newnie at this.
The project I´m working on is a dispensing machine that needs to dispense resing along different graphic shapes.
Since the people who will be using this has no coding knowledge, the idea is to use a CAM software so we can start from a graphic (either image or vectorized).
The biggest challenge right now is to be able to vary the dispensing rate when the line is narrow.
For example, if I need to dispense the resin along a word written using a script font. The line with is not constant, so where it´s narrower I need to either move the nozzle faster (X and Y axes) or to dispense the resin slower (Z axis) so I release the proper amount of resin.

How can I do this starting from a graphic??

Can this application be thought as an engraving machine using a v-shaped tool where the deeper the Z axis goes, the wider the line?????


Thanks for your help

If you have a second drive on the Z axis (slave motor) you can make the slave adjust the flow rate of the resin. if you calculate the rate and drive it proportionally then you may be able to use an engraving routine from vcarve or the like.
