Build Your Own SLA/SLS

I everyone, I'm building a LittleRP from scratch, I already sourced most of the materials and already 3d printed the parts and lacercutted the panels. Despite having a Prusa i3 which I mounted from a kit I never entered the electronics much so regarding the LittleRP I have the following questions:

Which Arduino should I use? Is the Aduino UNO enough?
Which is the apropriate shield?
Where can I find the schematics and the PCB for the LittleRP controller?

Thanks for your help!

Any gcode interpreter should work, you can use a ramps board if you would like as well.

As for arduinos, we need to run GRBL so it needs to have a 328 chip, which the UNO is the most common.

Here is a link to the PCB layer files:


You could also use any GRBL shield.

Hi there Brad, thanks for your answer and for sharing the PCB. In the meantime I found out your store and already ordered the PCB you are selling, it looks top quality.

When will you ship it? Thanks for making it available.

I will source a Uno or a compatible locally. Do you have the reference of the stepper driver?

Thanks once again.

Thanks, will ship soon.

You can use any reprap style stepper drive, I use the drv8825 but you can use allegro's etc.

Hi!
Ceramic capacitor and a resistor... What parameters?

10k resistor
.1uf ceramic capacitor
100uf electrolytic capacitor

Thanks!
