Diy it?

@Rylan
The structural parts were laser cut from "ABS", correct?
Did you experiment with Acrylic? Did it work?

Apparently, laser cutting ABS produces Hydrogen Cyanide...sooooo, my local maker space will not allow it to be used even though it is well vented. Can't say I blame them!

Acrylic is a safe plastic to laser cut.
I got to test out the cutter tonight and I cut a few parts. Just need to review to assembly instructions to test them out. :-)

Acrylic works and its is what we original planed to make printers with.. abs is better because acrylic often breaks on the fine snap fit tabs, but it still works
and a bit of hot glue can solve any problems you have with it. I think that 1/8 inch birch plywood would also work and so would petg. petg would be the strongest.

We have been doing the parts in 3mm thick plastic but because we designed in openScad it should be relatively easy to cut parts from other thicknesses
try playing with the SheetThickness variable in the openSCad files.

Sorry Im not in here answering more questions right now.. Im in the middle of moving, so I spending lots of time boxing and cleaning, loading trucks etc.

@thej, it should work assuming you have a sheet at approx the right thickness (I think I had measured it at approx 3mm thick), and the gasses released are part of the issue with the FFF printers and abs also

I'm still trying to find the most current version of the structural pieces in the git repository.

I printed the "all.dxf" file on the laser cutter last night and when I compared them to the assembly animation Rylan posted (page 3 of this thread), they are NOT the same!! These are possibly the "oil dampened version" as discussed in this thread.

In "PeachyPrinterHardware/peachy_production/" these files here appear to be the scanner.
In "PeachyPrinterHardware/peachy_printer/ there is a collection of SMC files that COULD be the right files but I can't open them to verify.
I know these SMC files were created by the Laser Cutter's software but what is that software and can I download it?? (Ok, Duh, it's "SmartCarve")
Are there DXF versions of these files somewhere?
Has someone found the most current files?

The laser cutter at my local MakerSpace uses RD Works (I'll be getting a copy soon). This outputs RDL files not SMC. I can not open them with RD Works :-(

Hey there, that repo is all old stuff, you want this one: https://github.com/PeachyPrinter/pea...terhardware1.0

Totally threw me for a loop at first to!

MOST of the items have .scad files for them. This is a format used by OpenSCAD, it's really just a text file containing a script that defines the object. I'm not sure about converting this to RD Works, I do know that it can output at least a .stl file.

[thej]

Thanks! I dug through those files before but I really didn't know what I was doing yet ! I will check them out again :-)
RD Works will take a DXF so converting the SCAD models to DXF will work just fine.

The galvo works with an electro-magnet, a well modelled system can take that into account and compensate the inertia. Am I wrong? Certainly for faster speeds it gets tricky but looking at the current state it just looks way too slow. If the resin curing speed is not the issue then at least a 2x speed increase would be great if possible.

Please read carefully what I typed before: it is a combination of factors: cost (laser diode prices increase substantially as they become more powerful, goal was a sub C$100 printer), curing time (the resin curetime is the main determining factor) and accuracy (if it takes x seconds to cure a layer either way, move slower as it increases accuracy)...

Is there a datasheet for the resin?

You'd probably want to contact makerjuce for that kind of info, as they were the ones making the peachy resin.

Can't speak to what was used with the later stuff, but for the beta users it was "PeachyJuice Stiff or MakerJuice SubG/SubG+ resin". I got Stiff in the beta shipment.

You can search the internet for the Makerjuice SubG/SubG+ MSDS sheets - what I just tried is a little different but I can't seem to upload it due to the file size (197 kb). probably not current anyway, it was from 2014.

I've not seen one on peachyjuice, but any UV curable resin should be usable, so pick your favorite one...
