Hi oni305,

where can I get one of the boards or *.BRD file to start my own laser project?

Hi oni305
I see your Raster 2 Laser GCode generator at github now works with the latest Inkscape 0.91 which is excellent as it automatically maintains the correct size of the original artwork. I have however got a slight problem when making PCB boards on my laser machine, because of the small amount of backlash inherent on all machines I end up with a small amount of overlap of the laser when it goes one way and then the opposite way. This causes a real problem when making narrow PCB tracks it ends up becoming sort of a zig-zag track. Do you have any suggestions how it may be possible to only turn on the laser when it goes in one direction. I think that would overcome the problem.
Cheers Alfred

 

Hi goodjob oni305...i hope it does PCB etching ...any possible to use only schematic for laser driver setup using on rampps board or cnc shieldv3 because dont need those steppers(from your board) in this case more thinking for expansion my own boards just editing the code and voila should be working
wants to build meself or buying jtechphotonics.com only laser driver solution but exceeds my budget in shipping and customs say about almost in total 250 dollars... absurd

I just read you still have pcb boards how many$ where from? possible to use drv8825 steppers?

 

Looks good I hope to be able to use one of these on a future project, with regards to the homing cycle that's a good idea if you don't wish to edit the grbl config.h to remove z from the homing cycle.

Are the boards for sale or ?

These are for blank un-populated pcb's?

Thanks,

Anybody please help me. I got a problem like this
I tried to install on 3 computer but it didn't work.

This is an error code :

Hi oni305,
thank you for your Inkscape extension "Raster 2 Laser GCode generater".
It is very good to engrave jeans clothing.

Hey, you are still working on it and also with laser driver PWM, nice

May you remember you send me some pcb's of the first version to germany, now im very interested in your updates, would you like to send me the shematics?

Did you needed to modify GRBL for the new driver?

 

Thank you so much!

Well, i did so many diffrent things, that i never finished the boards. But i've been getting all parts needed and still willing to do so.

About the GRBL you use for PWM, you switched the arduino pins 12 and 11, which is pin 15 and 16 on the ATmega chip and used the stock GRBL with spindle PWM right?

Im actually planning to integrate this also in Marlin, as i did with a PID closed loop AC Spindle controll allready.
Maybe i can manage to have a gcode supported way of controlling the laser PWM from Marlin in a better way too.
But yeah, i really need to finish this soon. Will get back with some results here as I'm able to finish this.

Keep up your awesome work.

 

Hi Oni, great job!!!
where are you come from? I would to buy your last PCB and the láser driver
