3D Printed Lawn Mower - FAQ's


I have a 200x200mm print bed, can I print the project?


Many of the parts are larger than 200x200mm.  This project was really designed for a print bed of 300x300mm....  There is a 200x200mm remix version of the project being created by Peck.   Check it out on Thingiverse for the latest status of the remix.

If your printers too small, you can always start to build a ReP_AL COREXY printer ;)


Where can I get the parts for the project?

All the components you need are available in my online shop... 


WiFi and Mobile APP

Yes - Done!


Can you include a rain sensor?

 Yes.   Done! :)


How long can the mower mow?

I used a 3S 18650 Battery Pack. I used 6x 2400maH 3S packs in parallel making a 20.4Ah pack.  This gives me (on a flat garden) a mow time of 3 hours.


Can I modify the software?

You can modify anything you like...  Its ARDUINO    The nice thing about this project is you are free to make the mower do whatever you like.  Want it to bring you a cold drink in the Garden...  then program it to do so....   :)

But seriously, there is really no limit to the modifications that can be done to the mower.  There are many sensors available for Arduino that do almost everything and there are plenty of empty analog or digital outputs free on the ARDUINO MEGO board to plug them in to.

I am continuously improving the software and hardware...  please check back for new code and new updates on what the mower can do. 


Can I have the CAD Files?

available on my GITHUB site here:


Can the mower mow in a pattern (not random)

Not yet.   Its high on the to-do list


Can the perimeter wire be split into Zones.

I didn't implement this as I don't need it.  But theoretically it would be possible with a relay switch.  the zones could be fed back to the relay switch and turned on and off as needed.


Its Arduino - anything is possible.....


My Perimeter Transmitter is not working:

First check that all connections are correct and that your using at least 20-30m of quality perimeter cable to give enough resistance to produce the signal

If your perimeter wire transmitter still doesn't seem to work after loading the Arduino sketch. Try with these alternative settings in the Arduino sketch before uploading.
