Diy it?

Wiki and discussion.

There is lots of info in this forum where we were/are :S supporting those who actually have a V1 kit

Your Right oninoshiko It will take much time and effort for the community to get a grasp of all the work reviled.
I can only help so much as much of the work is only fully understood by the engineers that did it....

Here is a incomplete list of things I have a deeper understanding of:

-There drip bubler system with all the hoses ( me and Erik came up with that)
-Printer assembly ( the animation work in the above video is all me)
-Over all printer functionality, names of all the parts and how they should behave. Fundamental concepts like how dose magnetic dampening , spring force, drip counting work.
-openScad files - I could be of use here, Erik wrote most of the code for this but we invented each part together. There are a few parts that are my code like the dripper, and the the newest laser aperture.
-Laser safety, laser diode operation, laser testing,
-Resin behaviours, surface tension , viscosity, adhesion, surface flow, oxygen inhibition etc. Gavin worked on this as well
-Printer testing and debugging, I wrote some code called G code writers for testing the printer. Gavin worked on this as well
-slicer settings and bugs.
-printer maintenance
-safety interlock features
-coils ( me and Erik designed this)
- parts and part specs ( Nathan did alot of work here with supply chain communication)
-magnetic dampening ( me and Erik designed this, with a great Ideas from Tony and Scott and a very wise guy from the US military. )
-mas production processes, I designed many of these my self and built task specific machines for production, many of which are not documented at all. There designs live in my head.
with a few important numbers jotted down in a project note pad.
-stepper motor moving platform (instead of dripper) - designed and coded some of these my self. Erik and Will have added to this now also. I have a very good understanding of features that handle resin flow.
- peristaltic pump design - Erik Did lots here To.
- software user interface - I understand every setting and its purpose, including how to add additional functionality via arduino
- hardware "dead ends"- I did many many hardware spikes, printers that have only one mirror, printers that have coils right on the moving galvo, air dampening, oil dampening, etc. I have tried many many very different ways to make this printer.



And an incomplete list of Things I dont know the iner workings of (don’t let the size of the list deceive you these are BIG things) :

- haven’t read a line of firmware code, I know how the firmware should behave but don’t know how to change it, This work was done by Tony and Will.
- software- I have very little knowledge of the code, I know how it should behave but don’t know how to change it. This work was done by James
- Circuit board design - again very limited knowledge here, I know how it should behave and I can rattle off a few external behaviours like Max 100 mA per coil, and 48 MHz chip but Tony single handedly designed our V1 circuit.
- USB driver - all I know is we send positional data to the printer about 1000 times per second using the proto buff protocol, Tony and James did this work so well I was only involved in the first meeting
- old audio version of the printer Scott and James cooper did most of this work.


My day Job at peachy Is team development lead, A normal day for me at peachy is to communicate with about 6 employees, engineers, programmers, drafter, physicist etc, making sure they have what they need to work
and that they are working towards the right goals despite the problems that each of them run into every day. After 8 hours of that, then I would also do a night shift working on some other part of the printer, that didn’t have an engineer delegated to it yet.

Hope that helps people get a general understanding of my knowledge,
One thing is for sure this project has been a team effort ever since I joined a my local hacker space.
No one person knows everything about it, but Im definitely the guy who knows who to ask

This is great to hear, Rylan, would you be able to provide the community to those who might still be interested with coils/other difficult to manufacture parts?

[Mjolinor]

If there are enough people then you should stick with the original PCB. You can get 10 blank PCBs made by dirtyprototypes for $20 or so. I am sure that someone will take that task on if there are enough people to pay for them.

Hi all.
I'm glad we're looking at DIYing this. It was something I always thought would happen even before the "big bad news". Just like reprap....?

Times like this we need to 'lay' everything we have on the table and make an assessment.


What hardware does Peachy inc have in either storage or still waiting to be delivered?
What skills does the community have?
Locations of the community members?
What’s left to finish, anything?

My thoughts at the moment. I know we can do this and slowly work to bring the peachy from the dead. It will take time but that’s how things go.
The mention of using a wiki is a great idea.

With regards to distributing the remaining stock. One way would be for someone to take that take on, then maybe offload distribute to volunteers for different countries?
The first person in this chain should ideally be local to Peachy inc (to reduce the initial shipping cost).
I’m more than happy to be a distribute point for the UK (I’m South Yorkshire based).


I’ll have to look at the regulations regarding shipping laser diodes. I’m not sure but I think you only need the certification if it’s a user product, which in our case if it was just the component we’re clear (after all, it was shipped to peachy inc).

One of the most important things to consider. Who is the driver of this? There always needs to be someone keeping an eye on the ball or things really start to slip or simply donot happen…. Rylan….. or are you a broken man now? Lol.

Last but not least, I made a joke.

With a peachy printer and a big enough build area you can build a boat. With enough backers you can build a house.

My few thoughts at the moment.
So… Who wants to build a wiki? (It’s easy btw).

EDIT: My skill set:
I've worked with an arduino, well, more of the atmega chips directly (cheaper, something like 75p each) so I can help with that side of things.
I'm a little rusty but still sharp. my gut says try an arduino... just because they're so common... Even reprap changed to the atmega chips.
Other skills, coding, I've done a good chunk of it, but it's not my day job (I'm a sysadmin for a datacentre).
IT man... and I have a normal fdm 3d printer.

Oh I'm north lincs,

Skillset wise I've tinkered with arduinos and I've quite a bit of experience lasercutting things.

Not Broken at all
Currently spending some time trying to fix this in a big way by talking to investors.
The beautiful thing about a freedom respecting project is that no one persons actions can kill it,
but any one person can keep it going. Great work everyone, great Ideas here.

For big prints perhaps a cluster of printhead's ? :-)

[oninoshiko]

OK, I'm getting close to having everything in position so I can start simplifying it. Here's what I don't get:
How does laser mount A & B attach/work?
How does static dampener A & B attach/work?
What is the "standoff" for?
How does the PCB mount?

most of what I've done so-far, is from looking at the completed images but these four parts differ enough from what I've found that I'm having trouble identifying where they go and how they attach. Any insight anyone can provide would help me out a lot.

EDIT: I just realized im working with the scads for the oil-dampened version, rather then the magnetic dampened version. That will have to be fixed.

mirror frame A is called "A" because its holds the first mirror that the laser hits, B holds the second mirror that the laser hits.
The 2 galvos in the peach printer are identical, they simply go in differnt places.

As you have realized your other questions pertain to very old verson of the printer.

I think you would be most interested to look at the blender animation ( work incomplete)
there you can see the V1 printer fly together.
https://github.com/Rylangrayston/pea...safety/blender

This animation was created with the some previous iteration of the files linked to above:



A big part of why we didn’t release these repo's earlier is because of the lack of documentation... they make sense to the employees that built them and that’s about it.
