Anycubic Photon Printer Owners 造訪社團 » sensor

Hi Owners I need some help.
When I press the home button my building plate stops about 15mm high of LCD screen. Is that ok? It never went all the way down to red led sensor.

Also if i set Z should it be possible to move build plate onto LCD quite hard? Or is there a safety stop and mine just doesn’t word.

Hope someone can help

Thanks
Chris

does anyone know part number of the Z axis optical sensor. I know its an omron brand but i cannot read the part number. Thanks

Hello. Thanks for the add.
I've done a search and didn't really come up with much. I have posted this on Reddit also.

My photon was working perfectly yesterday. I've done about 10 prints since I got it just over a month ago.

I went to print today and it wasn't happy one bit. The print platform failed to stop lowering and keeps making contact with the bottom of the printer and keeps trying to go further resulting in the motor making a grinding noise.

This happens when pressing the home button or starting a print. It keeps trying to go lower. No error messages come up yet I don't let it do it for long to save the screen. Luckily it hasn't damaged the screen or the film. I've also removed the print platform and vat, but it still hits the bottom and tries to keep going.

I've opened it up twice and I suspect the stop sensor is not working. The red LED illuminates, the connection seemed a bit loose but was initially hot glued from the factory to stop it falling out. I've tried squeezing the connection together while Homing still with no luck.

The little metal tab that slots into the sensor is there and is in tact.

Any ideas?

Hi, anyone ever wondered why the Photon doesn't have end-stop switches? I mean obviously it's not an expensive device compared to most high-end SLA printers, but for us common folks it is not cheap either. It is very easy to ram the top or bottom with the build platform, especially if you are new to these devices.
Since you can't have total control (like disabling peel-motion, locking rail movement, etc.) it seems it is aimed more towards the general user than the tinkerer.

(
before someone mentions the bottom switch:
-the one it has it uses for the leveling reference, not for safety
-with a pressure sensor on the bottom, it would be a cheap fix and would allow for leveling and calibration while function as a safety switch
)

Apologies in advance for all the newb questions I’ll be asking over the next couple of days. Will this work for a curing station.

✅ Solved by moving the blade back into the right position for the optical sensor (back bottom)

original post:

My photon completely ignores the Z=0 leveling setting. This is not a mechanical problem as the known issue listed on github. The printer initially worked - probably a sensor damage. Updating to the newest firmware did not help. Any suggestions?

So... is it common practice to have to refill the resin tank halfway through a print? I'm pretty much out $40 in resin because twice now, there hasn't been enough to finish a print (and unlike FDM printers, there's no runout sensor, so it's just a complete waste).

If I put more resin in, it is too much and covers the ball joint.

So... is it normal to add mid-way?

"Imgur user "darkshark" presents a pretty convincing way to thwart the sensor: take a picture of a fingerprint off of an object like a wine glass, add some depth to it in 3D editing software, and then print it out on a 3D printer. Specifically, darkshark used the Anycubic Photon 3D printer, a resin stereolithography printer that can be had for under $450."

I am very happy to announce the second version of ESParaSite Data Logger!

v0.2 - Second Release - Bed Bugs- 2019-04-07
- Adds support for the BME280 Sensor (For Ambient Temperature, Temperature, Humidity and Altitude.)
- Nearly all code has been refactored! (I just love saying that) Since we are relying on 3rd party open source libraries,
each one is a bit different in how it behaves. Refactoring has prioritized standardization across the main functions and attempted to limit snowflakes to the functions that talk to the various sensor libraries.
- HTTP server re-created as RESTful api with JSON returns. (Currently GET only)
- Sensor data has been organized into 4 key groupings or "classes"
- Ambient - The room an environment in which the printer lives (Temp, Humidity, Barometric Pressure, Altitude)
- Chamber - The printing chamber itself. (Temp, Humidity, Dewpoint)
- Optics - The LCD Screen and UV LED (UV, Visible light, IR light, LED Temp and LCD Temp)
- Enclosure - The base of the printer that contains the MainBoard and Optics (Temperature)
- All classes have a timestamp as part of the return value.

Check it out! (v 0.2 renders a lot of the documentation out of date, I will update ASAP!
