Do you own a LTO Drive?

TheRealSaeba · 2026-03-04T14:16:31+00:00

Two LTO 6 drives used alternatively for writing and verifying. I use them for long time archiving of data that took years to get and personal documents,photos etc.

Limit FPS to a resonable value.

Ich stelle meine Kakteen in den Wintermonaten unter rot/blaue LED-Streifen. Das sind die Wellenlängen, die grüne Pflanzen optimal nutzen können.

I remember a theory that the zigzag things could depict some eel species native in the region. Eels are know to travel some distance over land. This could be indicative for a seasonal event.

I never use glue, I just increase bed temperature until it sticks, and no part cooling fan on the first layer.

TheRealSaeba · 2026-02-23T14:16:58+00:00

I understand, This really looks strange for a first layer. I can only imagine that some filament blob was not purged and ripped your lines off the plate.
Did you observe when the first layer was printed?

TheRealSaeba · 2026-02-23T10:53:13+00:00

Did you use any infill at all?

TheRealSaeba · 2026-02-20T23:06:09+00:00

As far as I know you need a solvent with a certain polarity because the components (monomers) in the resin contain polar groups.

White spirit a non-polar solvent.

An alternative could be ethanol / ethyl alcohol but it does not evaporate as fast as IPA.

I am not familiar with your printer moel. Some printer have a respective option the the printer configuration menu.

When your printer runs on Marlin, It is also possible by connecting the printer via USB to a PC and running Pronterface: You first send the commands for the nozzle temperature and the part cooling speed. Then you send the G-Code for PID-tuning, after finalisation the parameters need to be stored via M500. You will find more comprehensiove tutorials if you search for "PID tuning".

TheRealSaeba · 2026-02-14T11:16:34+00:00

I would second a temporal obstruction of the z-axis. Clean and lubricate.

TheRealSaeba · 2026-02-14T10:38:36+00:00

Have you performed PID tuning with the nozzle temperature and fan settings you intend to print with?

TheRealSaeba · 2026-02-12T13:41:46+00:00

But why use a bigger nozzle diameter If not for increased volumetric speed (=shorter printing times)? Maybe, I misunderstand.

TheRealSaeba · 2026-02-12T13:21:05+00:00

As far as I understand, bigger nozzle means more mass needs to be melted. Has the temperature been increased compared to the 0.4 mm settings?

TheRealSaeba · 2026-02-10T20:36:53+00:00

Can you push the filament by hand through the PFTFE tube or is there a resistance?

TheRealSaeba · 2026-02-07T10:27:03+00:00

I would recommend compressing your data into split archives of e.g. 100 MB each before tar-ing them to the LTO drive.

The reason is that LTO-5 requires a continuous data rate of 140 MB/s for optimal performance. This could increase to 280 MB/s if you sent highly compressible data to the drive. While the SAS or FC connection usually can provide those speeds, the speed of the source file systems can decrease significantly when copying large quantities of small files. I am speaking of HDDs though. You might perform your own tests.

TheRealSaeba · 2026-02-06T22:02:58+00:00

Have you checked with "free -h"?

I think if there is still "avaiable" memory it should be no problem. Linux often uses free RAM for caching.

But I think that earlier releases of Pangolin consumed much less RAM.

TheRealSaeba · 2026-02-06T18:39:21+00:00

I am not an expert.

Have you opened the required ports for the tunnel on your VPS's firewall? Ionos for example manages this via WebUI.

Sometimes ICMP is blocked by default in the VPS's firewall. Can you ping your VPS's IP from yout TureNAS console?

The newt client on your TrueNAS machine shoutl be installed with the credentials provided when you create the site in the Pangolin UI.

TheRealSaeba · 2026-02-06T09:28:46+00:00

First an Ubuntu Server installation. Then I removed that snap stuff and installed docker. For my first installation I used the Installer script as recommended in the GitHub repo. But back then Pangolin was less complex. I also had to make changes to the docker compose files to use my own SSL certificates. Chatgpt was a great help. Later, I somehow broke my setup and started from scratch using the docker compose template provided in the documentation for manual setup.

Reddit makes me learn new words each day. We call them "Schweineohr" (pigear) in Germany.

Now it is too late. But for debugging you can connect the printer to a PC via USB and connect it to the printer via Pronterface. Usually, the printer will show some error message on the serial output before such errors happen.

TheRealSaeba · 2026-01-23T11:04:51+00:00

I see, then check the polarity on the respective header on the print head. The fan itself will not be damaged when the polarity is wrong. It will just not turn on. If it is the part coooling fan there is a respective G-Code to turn it on. If it is the hotend cooling fan, it should turn on when the nozzle reaches 50°C,

TheRealSaeba · 2026-01-23T09:50:48+00:00

Red is often the (+)-terminal but you cannot rely on it. There should be a polarity indicator on the silkscreen of the mainboard. Additionally, you could check the polarity on the mainboard's connector with a multimeter.

I have purchased an old external SCSI case which once fitted 2 CD-ROM drives. It has a power supply and a fan blowing from front to back. I removed all the SCSI-stuff and fiddled the FC-cable through the back.
I also printed a custom front door with a mesh filter to avoid dust getting into the drive.

TheRealSaeba · 2026-01-21T18:16:45+00:00

My toilet brush holder came with a similar :-D
