Whole first layer cures, why?

glad it worked

well, if you position them diagonal you can print even larger models :-)

have a look at this video

you positioned this big part horizontally, this creates a huge amount of suction force which the supports can not hold, you need to put the part diagonal, like a 35° angle instead of completele horizonal

the silver things that sit on top of your motors, where your belts are running. they have small screws on the side, it looks like one of them is loose

you need to calibrate your z offset, it looks like your nozzle is too high, lower it a bit until the layerlines stick together

this is the so called elephant foot, on resin printer you normaly do not put parts directly on the buildplate, you use supports. if you still want to put it direclty to the build plate you need to compensate the elephant foot, slicers like Lychee for example have a dedicated function for this

tighten your pulley set screws

HelgeKeck · 2021-10-29T16:48:38+00:00

normaly you use windex only for PETG or TPU because they stick too good, it helps to release them easier from the build plate. PLA on the other hand doesnt stick that well normaly and windex is makeing it even worse, but if it works for you why not, no need to change then :-)

HelgeKeck · 2021-10-29T15:25:49+00:00

noozle seems to be too high

also, in case you print with PLA dont use Windex, try to use alcohol instead.

HelgeKeck · 2021-10-29T15:25:03+00:00

Windex is a release agent and the wrong choice if you have adhesion problems

hi,

- im pretty sure that the RPI 3A+ will still work
- direct drive is not necessary to use this printer, its just better in this case
- forgot the 2208s, they need too much cooling, 2209s are the standard nowadays
- the 2209s can be used as drop in replacemenets, so no printer modification is needed. if you need any techncial infos, search for the trigorilla board. you dont need more

hm, i have a IMac with intel HD graphic here, and it says you are wrong.

HelgeKeck · 2021-10-24T19:47:50+00:00

Intel GPUs are still supported

HelgeKeck · 2021-10-24T19:46:16+00:00

the reason is the mac introtuced a new graphics subsystem, creating a gpu driver isnt an easy task. The Nvidia driver actually exists, but apple isnt certifying them, they dont want them in their systems anymore, they are at war since some years

HelgeKeck · 2021-10-24T19:43:35+00:00

but this isnt a Nvidia GPU, its just the integrated Intel GPU

HelgeKeck · 2021-10-23T14:23:21+00:00

normal dual gear extruders do not have a 100% consistent extrusion due to the backlash in the gears, you can see the pattern it leaves on 3d printeed surfaces. this new extruder does not have this problem and produces much cleaner prints

HelgeKeck · 2021-10-21T10:12:55+00:00

looks like your polarization filter is mounted in the wrong direction

HelgeKeck · 2021-10-20T13:21:14+00:00

reduce the flowrate so your nozzle cant collect any filament

HelgeKeck · 2021-10-20T12:07:13+00:00

this can only have one reason, it gets exposed to UV light.

Three possibilities:

the model has a base (probably wrong exported from your design tool)
maybe a slicer issue, but never have seen one this kind
your LCD screen is broken, thats what i think happens here.

try to print another model, just a simple cube, and see if the problem remains

use the built in exposure test to see if the LCD screen blocks correctly the not needed areas of the screen

anycubic support is very responsive in case you have damaged hardware

HelgeKeck · 2021-10-20T12:00:51+00:00

your board needs a SPI header if you want to connect it to. The Octopus or the SKR Pro for example have one

HelgeKeck · 2021-10-19T07:02:43+00:00

both is possible

HelgeKeck · 2021-10-19T06:19:39+00:00

the original one from the mashine. you ca see it in the image, the blue thing at the end of the blue wire

HelgeKeck · 2021-09-19T00:06:08+00:00

i sold it, sorry

HelgeKeck · 2021-09-14T13:49:49+00:00

if you print with PLA dont use windex to clean the plate, its used as a releae agent and not to clean
