LaserWeb for EggBot: I slightly modified Grbl to be used with a servo instead of a spindle. Now we can use LW3 or LW4 for the EggBot
M5 M5 M5 why isn’t it stopping?!
Neat. Mind sharing what you changed in GRBL? I am working on an egg bot but didn’t even think about using LW to send gcode.
You could also use my grbl-servo repo at https://github.com/cprezzi/grbl-servo
I named my eggbot “Woody Woodpecker”
@cprezzi Thanks for the info
Now i want to make one even more.
Ok. Finally a reason to test LW after just lurking for a while
This might also be usable for a pancake bot.
@Brandon_Jackson_MrJa Right, it should be usable for all types of servo driven pen plotters.
@cprezzi which pins are you using for the servo? I have a CNC shield and am not sure where to connect the servo. Thanks for your help.
@Dushyant_Ahuja It depends if your CNC-shield is for Grbl 0.8 or 0.9. If it’s 0.8, use one of the Z-endstop pins for the servo, if it’s 0.9, just use SpindleEn (PWM) pin.
Do I need to change anything in the code - or is it all configuration? I’ve never used grbl before - hence the questions…
Just configure grbl ($ settings) according to the wiki @ https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration
@cprezzi I set $30 to 255 per the readme in your repo but would you know why sending
M3 S0 or
M5 make the servo hum?
M3 S255 works fine as expected
