Installation of a camera inside the confines of one Photon S.

The camera is with a pi zero W in a Raspberry box. Notes above, a temperature and hygrometry sensor that I use to control the heating of the housing so that the resin is at a good temperature.

Hi Folks. Very happy with the result here. Background..

I am looking at ways to create a mask that can pickup the wearer's facial movement.. And these can be replayed on to a animatronic mask. For example - someone wearing werewolf mask can snarl, raise eyebrows, frown - and this is picked up and replayed via servo's, in real time, to the animatronic head.

EMG will not work - Sweat will invalidate the consistent readings due to conductivity.

This is my final design.. a small light weight linear sensor that will not react to sweat or moisture. The output is a simple analogue signal. Also most importantly - it needs to operate on the power of an eyebrow movement or other facial muscle twitch.

Now I have a resin printer I can print the parts an know they will be glass like smooth to stop friction.
What you see here are 3 x 3D printed shells. The graph paper is 1cm x 1cm for scale.
The PCB contains a QRE1113 sensor that has an IR light source and a Photo transistor. This board fits beneath the shell with the sensor showing through the hole.
The graduated laminated paper with the armature wire fits.. face down.. in to the shell channel.
A soft pad to hold it against the sensor yet still enable it to move freely will be applied on top.

The shell is fixed to a fixed spot above the eyebrow. The armature is glued to the eyebrow using an safe actors glue.
As the eyebrow moved up and down it will push the laminated paper over the QRE1113. The changes in reflectivity will cause the output voltage to changed and read by an Arduino or other. The accuracy is very good.

Enjoy

I had the vat spill in to the back of the printer because my printer fell backwards due to the weight of the open door. It was a hell of a clean up and unfortunately the homing sensor is not doing its job anymore and the plate won’t move when I press home. Anyone got a solution? Sensor replacement or some way to work around it? Thank you.

Does anyone else's Photon randomly have the optical sensor at the back fail when starting a print?

I'd say one in every 20-30 prints or so, I'll start printing and the bed will lower slowly as usual. However, upon reaching the vat the optical sensor seems to be ignored (no stopping or beeping) and the bed begins pushing into the screen making a worrying grinding sound. I usually rush to stop the print, but not sure what would happen if I just left it unattended.

I'm on the latest firmware (had it on previous firmwares too). Nothing blocking the optical sensor and it happens on my relatively old (12+mo) and new (1 mo) Photons. Anyone else have this or know a way to avoid it besides hovering at the start and panic-cancelling?

EDIT: FIXED! Thank you all! By messing with the power cable plugging into the back of the machine, I got the red sensor light to come back on. It appears as though there was a loose electrical connection happening.

Original Message:

Help! I'm pretty sure my end stop is malfunctioning, but I'm not sure what to do.

When I press the Home Button on my Anycubic Photon, the z-rod rotates until it hits the bottom, then continues attempting to rotate, making a grinding noise. Is there anything I can do? It's a new machine, and I've only ran a couple prints so far.

This is for the ppl using spacers an what not to stop the arm hitting the vat u shouldnt need any at all coz I’ve always wondered why my z sensor tab wasnt flat on the block (pic 1) sits on an angle and also wondered why it come with the small allen key screwdriver (pic2) an but ive noticed this lil hole at the back of the block at the top (pic3) took the allen screwdriver an what ya know theres a dam grub screw in there to adjust the z sensor tab position. so anyone having troubles with the block hitting the vat maybe have a look an adjust this grub screw.

220v Temperature controller + 8w PTC heater

PTC heater connected to side of Vat, dirlled and taped two holes and with two screws and some thermal greasse the PTC heats nicely the Vat and the resin, also drilled a hole in the Vat for the temperature sensor

So the photon is $299 on the Anycubic Website today. But I saw something interesting in the poorly translated english:

"PerformanceAuto warning if UV resin runs out."

Wait... what?

Is the warning that I have half a print? or have their updated the firmware somehow to detect this, I have no idea how that would work without additional sensors?

Well, it isn't a photon but I have an Epax x1 on the way. I need a crash course on resin printing! I have been using FDM printers for a long time which I know is completely different but I do have an understanding of how the resin stuff works.

Are there any good guides to read that you guys would recommend? Or videos.....

Things like model orientation, support placement, drainage for the resin on a hollow model (if that's a thing). I also am reading about chamber temps affecting the prints? Does the printer have a temp sensor in the chamber or do I need to add one

Also, a list of all the tools and accessories I need for resin printing!

Thanks everyone!

Can't wait to get started!

Edit: I have Simplify3d for slicing, not sure if that will work with the Epax or not. What about firmware? Stick to stock or flash it with something else?

Could someone post a photo of the metal tab that slots in to the stop sensor please?

I've just got a new sensor and want to make sure that the tab isn't bent too badly
