I have a K1 Max and mostly it is running great, however I get strange artifacts on mostly only the front side of curved objects.

I have lubed all the rods, and I have a Capricorn PTFE tube from the filament sensor to the hot end. I tried the printable guide for the tube to go into the hot end but it wasn't any better and I thought that was the culprit at first.

I have an extension piece to raise up the top glass.

I'm using Elegoo Rapid PTEG running at 240c and 250mm outerwall speed. This is mainly happening on the front side and anywhere on the build plate. Filament is dry and fed out of the Creality Space dryer.

These items are small netcups but it was also happening on the larger sections that they go in.

Using Orcaslicer and Arachne wall generator.

Any ideas where I need to be focusing my attention on?

I can't speak to multi colour perse, however the creality K2 went on sale today for certain countries and they have a 50% off sale for a limited number of units, they sold out today's stock but will have it again tomorrow then they will drop to 40% then 30%. Might be good if your willing to be a beta tester essentially.

The Prusa units seems to waste less filament.

I cannot comment on the noise of the Kailh browns at the moment as the board has been giving me some grief and I am waiting on new Elite-C controllers from Omega Keys. The keycaps came from ChocFox, the PCBs were ordered directly from JLCPCB using Foostans design, everything else was mainly through amazon. As for the acrylic, I have my own CO2 laser and just cut them out of 1.5mm clear, also from Foostans GitHub repository.

There are several good tutorials out there with parts lists and the build process, Marek Piechut has a good one called Corne MX 3.0 Keyboard Build Guide.

I wanted something super thin so soldered the controller to the board, I do not suggest this as I had some errors on my part and destroyed the controller, thus I'm waiting for two new ones before I can use the board, until then I'm stuck with my hand wired dactyl manuforms.

Just make sure you know what board and keycaps you want, sounds like the Corne chocolate to me, and pay close attention to the LEDs if you go that route, I have 600 that are of no use to me and am waiting on the proper ones.

Other than that have fun and there are plenty of people willing to offer help and advice between here and Discord.

I'm building a low pro Corne, Kailh browns with ChocFox keycaps, it'll be my travel keyboard.

I am using Elite C's.

 

Hey all, working on a Corne Choc, and having issues flashing the right half of the board with QMK Toolbox.

I am getting a validating error with:

822 invalid byte in program region, 0 outside region

This is the second controller as I had the same error on the first and assumed I ruined it when I was troubleshooting it and desoldering.

Ordered a new board and same issue.

I've cleared the EEPROM, there are not shorts or bad solder on the headers. This is a completely separate PCB.

Tried using QMK MSYS to reflash ISP (not sure I got that right, don't really understand it).

Get a blue led indicating power, reset button works to put it into bootloader mode, still nothing will flash on it.

Unfortunately on the first go round I had soldered headers to swap but was too tall for me, desoldered the boards and went directly to the PCB, as mentioned this is a new board on a new PCB, did not program prior to soldering.

Almost forgot, Teaching Tech has a great calibration web site and YouTube channel.

My first suggestion if you have a Raspberry Pi Zero 2w or better is to install Klipper. If that isn't a route to go down for you then Myers firmware was really good (not sure if it's still around since I went to Klipper).

I've printed so many miss for mine, spool holder moves to the side, filament guides, different spool holders with bearings, new hot end fan assemblies ,small tool holder that slides into the v slots. Covers for the V slots.

It's a great machine to learn and tinker on, some people don't like that but I really enjoyed it.

I've since switched to direct drive instead of the Bowden tube and added another Z rod and stepper. I have a microswiss all metal hotend which has been fantastic and I have put Noctua fans for the heat break. Also upgrade the Bowden tube to the Capricorn type, it is much better.

A magnetic build plate from Biqu was another good addition.

Almost forgot, I printed risers for the feet out if TPU and that seems to help, I probably would have tried the ones that the squash balls go into but these work fine. In order to print TPU with the Bowden tube you need to print slow.

Also keep an eye on the plastic handle on the filament extruder, they are known to be weak and crack, a good aluminum dual gear is a good low cost investment.

Search on Thingiverse and Printables for mods for the Ender 3 and you will be overwhelmed with your options.

Patience is a virtue, and remember there are no stupid questions and a huge community of people willing to help.

If there is anything else I can do to help, don't hesitate to ask.

That sounds like an interesting plan, my E stepper driver was what acted up on my 4.2.2, it seems to be working now, but I'd like to see your config in case I need to go in that direction.

Update:

I took everyone's advice and tried all the suggestions. In the end I completely disassembled the printer and made sure everything was square or perpendicular where it needed to be. I think maybe the dual z screws were binding, although when I took everything apart I noticed that I did not use the Y cable for both z steppers, I ran the original short cable to one motor and

the Y to another, not sure if that had any effect or not, but now the Y cable is running both z steppers.

It does seem to be better, but I still have the dip in the bed, which is still a bit of an issue for the BL Touch, but not nearly as bad as before. I may have slightly bowed it when trying to crank down the levelling wheels.

I think that the z screws were binding just enough that it couldn't keep up with the micro adjustments, I guess time will tell.

Thanks for everyone's input and advice, hopefully it'll run for a couple more years. If not then a replacement Bamboo might be in order.

Now I just need my resin printers to stop failing prints, but I think that's more me than the printers. lol

Thanks everyone.

It could be that I am cranking down on the wheels too much. Thought that maybe they were loosening off so tried to tighten them. I'll keep that in mind when I reassemble the unit.

Thanks.

I have aluminum wheels in place if the original, they seem to be staying tight, but maybe not.

I did notice that the plastic heater wire retainer is deforming in the middle, so maybe that is contributing, I will put a larger washer on it when I reassemble the unit.

Thanks for the comment.

I did a probe accuracy test yesterday, 0.002. So I think it's good.

I have the entire printer torn right back to square one. Will double check everything as I reassemble.

Did a couple prints yesterday with no BL touch, bed level the four corners, seemed good a bit of first layer micro adjustments.

Went to perform another print (same as the previous print) and the bed was out of whack again. The bed level test said that the right side was out half a turn on the knobs.

I'm starting to think it has to do with the dual z motors and not staying timed or level with each other.

Will see how it works once I get it all back together.

Thanks.

 

I've had an Ender 3 v2 for a few years now and have had mostly no issues. I've upgraded the hot end to a microswiss direct drive and a dual z setup (twin z steppers on a shared cable).

Recently started having issues with the 4.2.2 board and replaced it with a BTT mini SKR 3 v3.

Since I've put the new board in, I am having troubles getting the bed to level and stay level.

The height profile of the bed is now showing a dip in the centre (which was not there before). When I run a print it seems to be overcompensating for the dip. If I level the bed with the corner screws and don't use the bed mesh then it prints fairly good, but after a few prints the bed goes out of level again.

I can't seem to make any adjustments that help the issue. Yesterday tightened up all the screws (silicon spacers instead of springs). Releveled the bed and had a small dip in the middle and an overall height difference of 0.170 across the bed (normal prior to this was 0.310). Sent a print with bed mesh and mostly came out good.

Went to fire up a new print today and the bed height is showing 0.830 overall difference.

I'm not sure if it is a BL touch issue (the BL touch is a v3.1 and is original with a single 5 wire connector plugged into mini SKR) dual z issue (disconnected 1 in an attempt to level and didn't see much difference, the BTT has two connectors for dual z but run off one stepper driver as I understand it, I am using the y cable for only one stepper motor, while the other motor has its own cable).

I use klipper with a RPi zero 2 w.

I just can't seem to figure out that has been causing the issue since the board swap.

Anyone have some ideas as where to point me?
