Anycubic Photon Print Bed drainer STL – posted to Thingiverse

Whilst developing the Commodore 64 mini keycaps and iterating the prints, it came clear that the caps are little buckets that hold quite a lot of resin.

I’ve been holding the keyboard over the tray to drain all this resin out, and it takes “ages”

So, when you can use CAD and have a few 3D printers , you go and spend time developing a widget to optimise the amount of time holding a build plate at an angle!

And by “spend time”, and “optimise”, I mean, take longer doing in CAD than the total amount of time that would have been spent holding the bed in the first place

I present….

60 degrees! version 1

Total amount of time in CAD, and reworking, maybe 3 hours…

Total amount of time holding a bed to drain, maybe 3 minutes.

Number of beds to hold to recoup time in CAD…60!

So, after 60 prints, I’ll have broken even on the time invested in making the thing!

Here it is in action!

Version 1 wasn’t as optimal, it needed shifting over to the left by about 30mm to give far more clearance on the case for everyone not printing 25mm high keycaps to be able to use.

60 degrees, version 2!

Released on Thingiverse – right here – for free! works a treat.

Keycaps progress! Still a long way to go….

Hot off the printer!
Somehow I lost the E again

Wow! An exciting day today.

After quite some nervous trepidation, I finally shoved some resin into the printer and achieved my first ever resin print.

And, amazingly, some stuff worked! Significantly more than I’d expected to work actually.

I’ve been quite ‘scared’ of actually starting a print, I‘ve read too much about toxicity and fumes, which aren’t things you want with two young kids.

Well, I spent a couple of hours doing some final reading, and setting up on the dining room table. Levelled the bed, levelled it again. Shoved in the resin and…a Spectacular success for me!

I know the print failed mainly due to poor supports, some text is also too fine. Both were concerns with the cad and the slicer and easily fixed 🙂 there’s probably a dozen other issues I’ve not found yet also (it’s been 30 minutes since I wash and cured them fresh off the printer)

Next step, iterating, optimising . It could be done in a few weeks at print 3, it could be print 10 and take a few months , but now I’m over the first hurdle, onwards and upwards!!

Here’s looking at U

Anycubic Photon Mono Teardown 3

Only some thoughts on this one –

The PCB inside the Mono looks to be a custom PCB.

However, it’s widely known that Anycubic uses Chitu Systems drivers and panels

When I cracked open the Mono – I found really only 3 chips of significance…

An ANLOGIC FPGA – EF2L45LG144B –

and

GD32F307 Arm Cortex M4 controller

Having a nose around ChiTu’s website found this little device – The ChiTu L M1

Link to User Manual –

Have a look at page 12 / 73 and what do you spot ? – Item 8 – an ANOLOGIC EL2F Series FPGA Chip!!

AND….an STM32F407ZET6

Cortex®-M4 32-bit RISC core operating at a frequency of up to 168 MHz.

Sound familiar?

GD32F307 Arm Cortex M4 controller – Cortex®-M4 Core @ 120 MHz

What this means? – No idea 😛

BUT, what this could mean…

1- The Anycubic Photon Mono board is possibly capable of using a 4K LCD

also, i’ve spotted that Chitu systems sells an ESP8266 module specifically for their boards – it could be that Anycubic plans on selling their own, or just goofed up with the polarity of the header on the board!

And, finally, after all the above, that i’m going to publish anyway, i’ve also spotted

https://shop.cbd-3d.com/product/chitu-l-k1-controller-board-with-32bit-tmc2209-for-lcd-msla-3d-printer/

Which looks practically identical, also has the FPGA and the ARM board and is only 2k!, D’oh!

Anycubic Photon Mono Teardown – Part 1

A first look at the guts

I got myself a Resin Printer!

So, Naturally, before printing with it, I attack it with a screwdriver – or hex driver in this case……..

Here’s the first tear-down and initial dismantling of the brand new Anycubic Monochrome Resin Printer

Here’s the light source

And, some more photos..
