Photon Resin Calibration 1.2

(Link: https://github.com/altLab/photon-resin-calibration )

I looked over the files. There is a "test-mode.gcode" - file which executes gcodes on the Photon. After the test, the user has to execute "print-mode.gcode" on the Photon, to remain to normal printing condition.

Here is what I do not understand:

In "print-mode.gcode" are the following lines:

### ### ###
;(Acceleration)
M8008 I700
; The higher the acceleration the faster the overall print time. Too high risks losing steps.
### ### ###

Command "M8008" is setting parameter "I700".

And here it is: Some Photon firmwares includes such parameters files to set standard parameters on Photon after firmware update.

All firmwares i could see, uses the parameter "I900" for the "M8008" command. That is so in firmware 4.2.5 and in firmware 4.2.12 too.

So why does the "Photon Resin Calibration"-Utility sets this command back to "I700" instead of to "I900".

Do I see it right, that the "print-mode.gcode" should / could be changed, so that to command "M8008" parameter "I900" is set?

What is your opinion to this matter, Vinicius Silva ?

I would like to use the "Photon Resin Calibration" Utility and not knowing about changing the "print-mode.gcode" or not?

Thank you for your answer.

This group is for owners, and future owners of the Anycubic Photon Printers.

Resin Exposure tables, FAQs, Known Issues, Community projects and Tools, Tips and more can be found on the group's github at photonsters.org

The photon is a new resin based printer that is challenging the Wanhao D7, FLSUN -S Complete, and Micromake L2 in the desktop resin printer market.

✅ 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?

Hey guys, I've searched the photonsters github for that spreadsheet showing what exposures should be used for different resins but couldn't find it. Could someone please link me? Also, if I change the layer height from the default .05 to .04 I'll get better details but need less exposure correct?

Hello Guys! :-)

So i know how the search-bar works and i used it ... but still i need specific help.

I got my Photon yesterday, did the testprint [worked perfect] then tried one of my prints and got the T_100 error. So searched for it - found solution -> Update! So i did. And i followed the instructions step by step and did the update correctly. Still T_100. Then i tried another version (4.1.2 or so) and got a T_110 Error. Now i downloaded another version from Github (a much older version to check) and got a different set of files and i dont know exactly what to do with them and what to "print".

I've seen so many posts about continually failed parts lately. Until yesterday I was one of them.

I was attempting to change the settings in the g-code to slow the lift speed when I realized the current website firmware release has a typo in the parameter file.
M8015 P1 and M8016 P2
SHOULD BE
M8015 T1 and M8016 T2
(The number after the last letter is a speed setting, yours may be different)

These two settings control the peel and lift speed which is why, if you have updated the firmware with your new printer, it's ripping off the plate at high speed and supports are failing.

HOW TO FIX: search for the GitHub repository within the Facebook group, download firmware 4.2.5 and follow the install instructions.

Also: download the "Updated factory default translated g-code" from the GitHub. It will explain what all the g-code means and you can use it as a direct replacement for the Chinese g-code parameter file in the firmware by replacing it on your firmware USB stick.
To change any setting at any time, all you have to do is open it in any text editor such as note pad, then save and print the gcode file on the photon (you will have to reset your zero every time you do).

SECONDLY: I sanded my built plate and realised it was 1-2mm bowed on the perimeter from the casting process (proof pictures attached). This absolutely does not qualify as "flat" and afterwards I have no parts coming off the build plate.

If after you sand your plate flat (using a piece of sandpaper placed on a sheet of glass) you are still having problems, replace your FEP film and wipe a thin layer of pure PTFE grease (no rust inhibitors like would be in bike chain lube) on the resin side of the film. This will solve all sticking issues during normal exposures and increase overall toleraces by reducing stresses. This will not affect the resin performance as PTFE is highly stable.

LASTLY: Properly tighten your Z axis rail! Search on YouTube for a how to video. Mine shipped much too loose and I wasted time getting less than expected resolution. I now have zero play and no clicking when I wiggle the plate.

I'm shocked that this thing has the good reviews that it does, it's been a nightmare. But then again most of us bought it for the pricetag, post engineering is to be... expected?

So I'm reading more about the resin test. Looking on the paperwork about it on the GitHub I found wording I didn't quite understand. Maybe you other photonsters can help me out..

Under Column Number where you are trying to figure out your exposure time, it says "Layer time". Does it mean to be layer height? If not, what is layer time?

There has been some confusion between the various slicers, Anycubic Slicer, Chitu Slicer, Chitubox, and Photon Workshop.

A little story.

Chitu-CBD (CBD) and Anycubic (AC) are separate entities.

CBD's main business is OS/mainboard, firmware/software design, development and solutions for 3D printers.

AC sourced the core of the original Photon printer from CBD. The mainboard used in the original Photon is a CBD board. The original AC Photon slicer is a rebadged Chitu slicer.

CBD discontinued the original slicer (Chitu Slicer 1.3.6 and therefore Photon Slicer v1.3.6) and rebuilt a new slicer from the ground up. This is known now as Chitubox.

[Fun fact :
Chitubox integrates code and ideas first seen in the community projects VoxelOps, Validator, Rob's 3D photon Viewer and Photon File Editor Project.]

Chitubox was designed to support various printers. This includes Phrozen, Kelant, Elegoo, Sparkmaker, etc. The reason behind new Chitubox was to be a standalone slicer that would appeal to as many users across all platforms. So that they can be convinced enough to upgrade and pay for a future Pro version.

In the meantime, AC however developed their own mainboard together with their own slicer called Photon Workshop (based on Creation Workshop designed by Steve Hernandez.)

This is where the CBD and AC relationship for the Photon split. And this is also where the Photon-S entered the picture, and it was nothing like a Photon except in name.

As Chitubox was designed to support various printers, support for the S was also included in Chitubox version 1.4.0.

[ However, Anycubic then released a firmware update for the Photon-S that broke Chitubox slicing support with a proprietary *.pws file format. Thus forcing Photon-S owners to use Photon Workshop as the only slicer. ]

The original Photon can thus use the original Chitu Slicer, the Photon Slicer and Chitubox. Whereas the Photon-S can now only use Photon Workshop to slice files.

And they all sliced happily ever after. Except for the poor gimped Photon-S.

Wait. There's more. Unbeknownst to most, the little original Photon can also use the Photon Open Slicer, and it will always be free and unbeholden to anyone.

But that's for another little story.

Amazing how simple it is to find answers to most of the issues I've had. (Z motor stopping, USB stick, best exposure times and sundry other things).

I just went to https://github.com/Photonsters/anycubic-photon-docs/

Damn near everything you need there!!!
