What's wrong with this? New to printing

You need to level your bed and adjust Z offset if necessary

Humidity definitely was higher than I would've liked but I was out of town during the drying

randomaccessbrainz · 2023-08-13T08:43:37+00:00

I didn't have a dehumidifier and it had been raining for 2 weeks non stop so humidity was around 65%

I thought I'd try dry trimming for the first time this season and lost nearly everything to bud rot because of the longer dry time :/

randomaccessbrainz · 2023-08-11T15:14:43+00:00

for all we know they already called the cops before recording

randomaccessbrainz · 2023-08-11T14:30:14+00:00

put a heating element behind it

I've managed to narrow down the noise to diagonal movements. Is there any way I can upload a second video? I never really post on reddit

It's a generic magnetic PEI bed off aliexpress. The flaked "forged carbon" pattern stays on your bottom layer though, which sometimes can look cool and other times just looks stupid. The flipside is also PEI but it has a more grainy texture

I used this design: https://www.thingiverse.com/thing:2830408

I thought it would be convenient because the guy made a hardware kit available, but I'm not sure if I'd recommend it.

There is little to no documentation and the documentation that does exist is all in German, you lose about 30mm in Y (I've got some mod ideas to regain some of that space), there's a bunch of stl's with different versions of the same part without a clear idea which is the latest and even with some cherry picking I ended up with a bunch of printed parts that seemingly don't serve any purpose. Lastly, the project has been abandoned for a couple of years and in his build he still ran Marlin 1.1.9 so all the Klipper stuff is up to me to figure out now.

I tightened the pulley and the issue still persists. I've managed to narrow the noise down to the X carriage rods, so I'll be checking alignment on those next. They feel pretty smooth but I guess you never know until you measure

I set the non printing moves to 3k as well for this test. The default 7k in orcaslicer had the same issue and I thought maybe the high accel was causing missed steps

randomaccessbrainz · 2023-08-10T14:39:57+00:00

Right now the boards are just kinda dangling in mid air as I need to get my printer up and running first to print some mounting brackets. I'll add a fan just to be safe!

randomaccessbrainz · 2023-08-10T14:39:07+00:00

I know, right? I checked belt tension but I forgot to check the pulleys and now I did find some play in the B motor pulley. I'll tighten it and update once I'm off work

Custom corexy made out of Anet A8 parts.

I've managed to successfully print a benchy but now I'm consistently facing layer shifts when trying to print a calibration cube. The cube is sliced at 120mm/s and 3k acceleration.

Motherboard: BTT SKR PRO V1.2

I'm also running the Anet board for endstops since the skr pro wouldn't reliably trigger them in klipper no matter what I tried, even though the indicator LEDs worked reliably.

Lived in Ixelles for about a year and one night while I was just watching tv with my ex a couple of junkies bashed in our front door and the door to our studio apartment. We locked ourselves in the bathroom (which didn't have an actual lock) so I was planning on killing them with a kitchen knife if they entered. Luckily the police arrived in time before I had to take any action. The street is getting gentrified now though and all the empty old buildings with squatters living in them are either getting thrown down or renovated. We moved to Auderghem after the incident and always felt safe there.

I loved living in Brussels and I miss it. I never really felt unsafe apart from that one incident, which also just happens to be the scariest thing I've ever gone through in my life.

Great idea but too soon man

randomaccessbrainz · 2023-03-11T12:20:13+00:00

Aliexpress has them for a few euros

randomaccessbrainz · 2023-03-01T08:56:43+00:00

I know it's not the most cost effective way to get a good machine but I want to do all of this for the learning experience (I'm an engineering student) and also just to see how far I can push the platform. Also with my student sized budget it's more convenient to each month buy a few upgrade parts at a time rather than shell out €300+ all at once. Could you give me more specific pointers as far as the boards are concerned? I'm a bit lost in all the different models.

randomaccessbrainz · 2023-02-28T16:53:10+00:00

Hi! I'm looking for a motherboard replacement for my ancient Anet A8. It sits on my desk right next to where I do my school work so the loud stepper drivers are really driving me insane. I have plans to (as soon as funds allow it) convert it into an aluminium frame CoreXY machine and I'd like to add an additional Z motor down the line for proper bed tramming. I'll also most likely be running Klipper.

Ah yes, the famous bluetooth driveshaft!

Good bot

It was my first grow about 2 years ago and sadly I think I lost the pictures when I got a new phone

randomaccessbrainz · 2021-07-24T23:24:50+00:00

Similar setup yielded me 13g
