Good hint ! Thanks... plotter ! Yes... is more like a plotter than wood engraver... i dig it !

Speaking about "on off" plugin we are now fix some bug but this is a pretty good one for "line image" Repetier G-Code Plugin for Inskscape - Repetier Software after fix some bug the result is pretty good : source: http://www.g2kweb.it/public/images/6.JPG now i'm looking for a greyscale...

Benm yes what you say is "have a gcode based on feedrate" repetier have a M3 compatible gcode so: M3 S255 turn on the laser M5 or M3 S0 turn off the laser the problem is that most most application who i find work with varianble S value and fixed feedrate for example : M3 S0 is "white" M3 S200...

Sorry i don't understand the second sentence. For sure i need to modify the frequency something around 30Mhz. Now, i can modulate ALL the parameter : 1) user a tick interval and switch on and off laser manually with digital value 2) "" "" "" and write a classic analogwrite with variable...

Yes i know :/ The problem are : - Arduino mega standard frequency is around 490hz. Too poor :( - My china driver support only TTL and not accept Voltage under 5V so is not "pure pwm compilant" So i need to produce manually a Wave with a specific dutycycle range and fixed frequemcy. So all...

here a pic link : http://www.g2kweb.it/public/20151209_184644.jpg Yes is my delta used as engraaver :D The problem is : i use repetier firmware, at the moment only support ON/OFF mode, so no PWM :( Repetier forum say to use a software who use FEEDRATE instead PWM to generate the gcode, i'm...

here the driver, no sku no name on it :/

Hi all ! Anyone can help me driving a laser ? I need to know my range (0..255) to do greyscale engraving with 0,5W 405nm laser. Now i can drive DutyCycle , frequency and so on so... how to find a good range keeping feedrate fixed ? Any idea ? This is the main discussion : (comment #5 and...
