Re: 2nd Post - Understanding Supports in Cura

So, in most structural architecture, you want the support to touch to prevent sagging during construction and in most cases, those supports become part of the finished structure and are not removable. Where they are removed (say a temporary stud wall to hold up a ceiling while replacing a beam), the...

Re: 2004 LCD ( REPRAP_DISCOUNT_SMART_CONTROLLER )

You could try swapping the displays between red & blue, see if the problem follows the SD card slot. Worst case, you may have worn out the SD slot or controller. Replacement displays are ~$12 on amazon.

Re: 2004 LCD ( REPRAP_DISCOUNT_SMART_CONTROLLER )

Are you using the SD built into the display or the one on the mainboard (newer mainboards have it there due to signal integrity issues). If on the display, you may need to shield your cables to the display. Try wrapping them in tinfoil as an experiment.

Re: how to fix this kind of quality issue

I bought my son the same printer several years ago when we first got into 3D printing. Some of his prints were good, but then the quality went downhill. One of the biggest issues he had was the belt drive Z axis which started doing exactly what you are seeing. Then his printer decided to embed the p...

Re: Why is not Slicing?

Also, if your object is fairly low and flat, don't bother with a brim. Just use a skirt. The brim is used for models with very little first layer surface and decent height. Think of a tube printed on end. The skirt with 3-4 lines will create a steady flow of filament (prime the printhead) for the ac...

Re: 1st Post - Understanding relationships in Cura

The "Shell" is the outer layer of the print, and the settings relate to its thickness. Settings like how many lines are used to form the shell for example. This can help with surface strength (rice paper vs brick wall for an extreme analogy). For the best bottom surface, make sure the print bed is t...

Re: Selection of part in Creality Slicer

So, using your example stl files, when I mouse over them, they highlight individually (as it appears in your 'example layout.png' file). I can select and move by holding the left mouse button and moving one object. I can also hold the right mouse button and change the camera view perspective (tilt &...

Re: Selection of part in Creality Slicer

Ok, it took a bit, but I got it running on my Linux system (yea, I know it is a Windows app). This looks like a hack of an early Cura release. As a test, I loaded the Raspberry Pi Rack case files (5 objects). I was able to select each object individually and move them independently. Are you sure you...

Re: Selection of part in Creality Slicer

Erm, missing image.

Also, not familiar with that slicer. Most of us use either Cura or Simplify3D.

Re: My Firmware

I haven't had time lately to follow all of the new features. The Pause sounds intriguing though. Would help when changing filaments.

The runout sensor support would only be helpful if it actually sent out a signal via USB when printing from USB (something Octoprint, Cura, etc. could glom onto).

Re: Raspberry Pi 4 and Octoprint?

Not sure if it will boot directly, but there is no reason you can't have the boot loader on SD and boot to USB as the root device. In fact, I used to test this on TI Omap4 Pandaboards when I was doing Arm enablement work for Canonical (Ubuntu). I'd have to study up on the Pi 4 boot paths. It would b...

Re: OctoPi produces weak prints

Try just disabling Octolapse. I disabled it on my setup a while ago, (can't remember when), and haven't experienced any real issues recently. Sorry, I don't have better input on this, just my experience. As to power, I am using the authentic Pi power supply. Had numerous issues with using high amp c...

Re: New resin printer

I was thinking about getting an SLS printer soon. I know the quality is 10x better especially for smaller detailed figures. How bad is the smell of the resin? That would be my limiter, as it would be in my converted (hijacked) dining room with my other 3D printers.

Re: Begginer

Looks like a Hictop 3DP-18, I think. Very similar to my 3DP-17, except using the acrylic frame instead of the 2020 aluminum (was a cost savings measure I think). Roberts_Clif is the local expert on Hictop and Marlin firmware. He would be the best one to get the latest firmware from. You might poke a...

Raspberry Pi Cluster

So, I have a RPI Kubernetes cluster now. Built as a learning tool for work. 4 systems, using Raspberry PI 4B 2G systems, Power Over Ethernet (POE) Hats for each, and a 5 port 1G POE switch. All cases and the rack they're going in were 3D printed over a few days on my CR-10S. I'm still working out a ...
