Delivery No.1 - Build blog of the first V1.0 Peachy Printer in the Wild

[Builder1]

Hi everyone !! I finally have some updates to share :-)

New Pics !!
Gallery “Stepper Z-Axis Peachy”

“Brass_vs_Alum” is the new brass wire build platform sitting on top of the “original” z-axis build platform. The wire loop is 14cm long by 8cm wide. I have glow paper taped to the original build platform.

“Brass_in_the_Bucket” shows the wire loop in the build container. The old platform was too big and got stuck part way down so it had to be replaced with something smaller. The bar that the wire loop mounts too still runs into the bucket a bit :-(

“Brass&Mesh” is the wire loop with the platform mesh attached. I just used thin wire to attached the mesh and brass wire together.

“ButtonPad” is a control pad for moving the platform up and down. Two buttons to move it all the way up or down and two more for layer by layer movements. Upon further inspection, the arduino looks to only have 3 available digital IO left. Oh well… three buttons I guess.

What’s Next ?!?
-Wire button pad to arduino
-Update the code to use the buttons
-Firmly attach arduino and button pad to z-axis frame (harder than you would think)
-Mount Peachy (probably just rest it on the glass lid)
-Calibrate peachy to build platform height (which needs to be determined)
-I may also need to buy new resin. It's been about a year since I bought the last bottle.

What’s Next Next ?!?
In some of my next posts, I want to start talking about my software idea to improve 3D printing. I would love to get your feedback on it !!

More to come...

the worry for the materials is galvanic corrosion as the water is heavily salted, and dis-similar metals will give galvanic corrosion is ordinary ocean salt water

The brass and aluminum will have no problems with salt water.
The mesh (I think) is galvanized steel. It is the same mesh that Rylan had picked to ship with the Peachy.
I just checked some of my other meshes that have spent significant amounts of time in the salt waters part of my "drip" based Peachy. The mesh still looks good. I see no signs of rusting or metal fatigue on these meshes.

The salt water does force one to be cognizant of material choices!

Sounds like you guys have done a ton of work to get towards a working peachy-clone printer using whatever could be salvaged from the fallout of the project. I have hopes of eventually building my own Peachy now after reading through some of your accomplishments. Mostly posting here to keep track of the thread, but being a professional software developer and Arduino programmer myself, if there's any assistance I can offer, please please let me know.

Couple questions, I know initially the Peachy was supposed to run off of common sound cards, that was scrapped because everyone's hardware was different. In the meantime the Raspberry Pi Zero W has arrived on the market, and it is a known quantity when it comes to it's audio circuit. Could something be built around the audio-out on that board, or it's GPIO as it's far more capable than the older Arduino chips. An ESP8266 might also be an option, could be code-compatible with what's out there, and is bit faster. Plus Wifi!

Anyways just my $.02 and hope of eventually having a Peachy-type printer of my own some day.
