RE: 3D Printer called "Buzz Lightyear" Part 2 Marlin Firmware Mechanical Endstops (Ramps)

Hi Nate,

I came in to this post a little late.

I think you are saying that you want your printer to always begin at the stops so that nothing bad happens on powerup?

I agree that you should always leave the system at some initial position before you begin operation.

It is an easy check to make with the Boolean input from the limit switches and lets you enter the normal operation mode in safety.

Thanks

Very nice.

It is also a good idea to remind people that if something does not work out as well as you want, use your inner maker to do better. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-638a339d-b317-4c1f-8600-cf881f8b38c4/contentimage_5F00_1.png:16:16]

Hi Nate;

I am also in Wisconsin so I know what you are talking about brrrr. It is wonderful, what you are doing with your son. Sometimes it seems that they are not paying attention but they are like little sponges soaking up everything you do and say. When my son was a little younger than yours (40 years ago) I often had him in my electronics service shop with me. At the time I was servicing mostly audio equipment. When it came time for Mike to say his first words it wasn't mommy or daddy. It was "Testing One Two Three". I will be getting out of the cold of WI for a while but I will monitor your blog as I want to begin to learn about the 3D printing. Thanks for the opportunity, your son and I will both be wide eyed and interested.

Thanks John

You will definitely want to build a noise disabling mechanism into the reversing beeper, horn, siren etc [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8995abb4-38e4-46f8-b349-5f6f2393a21a/2480.contentimage_5F00_1.png:16:16]

Nice project!

I thought you might be able to get the safety issue fixed by choosing a weak link between the dump box and its actuation. Velcro?

And of course you forgot the horn / siren that you can disable at will [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-8995abb4-38e4-46f8-b349-5f6f2393a21a/contentimage_5F00_1.png:16:16]

Hi Nate,

That looks fantastic, I can imagine that's the kind of toy kids would absolutely love and even sleep thinking about! The lights would be a very nice touch. Also maybe reversing beeps?
