Builder1, could you post some good up close images of the galvos? (multiple viewpoints, good lighting, etc) I haven't given up on magnetic damping yet but it's been difficult to replicate what was...
I contacted a Makerjuice chemist and asked what happens chemically when resin goes bad but all he said was "Typically what you will see is the viscosity slowly increase and/or the resin will become...
No luck with the capacitor. There are still far too many micro oscillations that last many minutes after perturbation. I'm moving to plan B but this could take a bit as I need a needle sharpened on...
What kind of resin? Depending on the resin it could either be the polymer itself or simply the photo activator that went bad. If it's the activator you might just be able to find out which activator...
Interesting idea. I might try that but I suspect the damping coil simply isn't having enough of a current induced in it.
So I soldered the damping coil into a closed loop and that made no difference. Copper foil on the back also makes no difference. The oscillations are the death of this design even though I am able to...
I'm trying to design some incredibly cheap replacement galvos that could be used in any SLA printer for under $15/galvo using parts people probably either already have or can buy from Ebay. My...
Try giving Craftware a shot.
Re: the wet prints, if you're using makerjuice resin, I have some and had the same problem with the finish in my first tests of it. If its oxygen causing problem as Rylan suggested and as it may well...
Photos next time would be great. I have my own (unofficial) parts now and will be building my own take shortly if some upcoming galvo tests are successful. Thus far I've spent under $50 USD in parts...
You wouldn't need to measure the amount of resin used just the thickness of the layer above the saline and if it's not enough, add more. If the interface wasn't moving this would actually be quite...
I was thinking about that and ideally I would think you would want a system to maintain the resin layer depth at the desired thickness of each layer and then have the laser intentionally cure it all...
But with a more powerful diode it should be possible to speed up the laser to the limit of the accuracy of the galvo system. There might be hard chemical/physical limits to the curing speed though so...
According the graph from the summary they should have box loads of them but not enough for everyone. According to the extracted data from the graph they have around 1200 coils but many other parts...
So I think I'm going to try and build one of these the Lego/Arduino route as a first attempt and then maybe upgrade to a dedicated solution later. What kinds of coils will do as substitutes? Are the...
Wiki and discussion.
A hastily created wiki. If a significant number of people other than myself use it, I'll consider moving to private servers with standard wiki software (porting over all work of course). If not, it...
I tend to assume the best of people until information to the otherwise presents itself. From what I can see this is not a good-cop bad-cop deal but if it is I am certain it will be discovered by the...
@rylangrayston, I have a little electrical experience that might be enough to make an Arduino version. What sort of specs does the peachy board have? I.E. At what frequency are the coils driven at...
Rylan, obviously Peachy as a company has suffered a huge, possibly permanently, project ending financial loss. I have a few questions:
How many beta printers were shipped? It says in the report...
The simpler method is to use a pump with two tracks whose rollers are 90 out of phase and then follow that with a permanently trapped bubble. Imma draw a shitty paint thing to illustrate....
You'd want to be careful with the gas gradually dissolving into the saline though when you create a pressure differential like that. Then it could off gas as soon as it goes around the bend and...
Looks great. I'll have try this myself and see how few components it will take to make this measurement accurately. Does the 1.0 kit have any spare GPIO pins or are they all taken?
Capacitance would depend on the dielectric constant which also depends on saltwater concentration so I don't think we've saved much by measuring capacitance instead of resistance.
Laser...
