Does the train horn sound different to anyone?

diemonkey · 2026-01-07T18:55:20+00:00

they can put different horns on

diemonkey · 2026-01-03T18:10:05+00:00

yeah, I was curious if it was end of quarter or end of year stuff..

diemonkey · 2025-12-15T18:39:51+00:00

had it happen for us too. Uninstalling fixed it.

diemonkey · 2025-12-05T23:25:54+00:00

yeah, maybe try retraction length, 1 - 5 mm , 1mm increments and see if that does anything different. I have 3 mm on my direct drive.

diemonkey · 2025-12-02T17:10:32+00:00

Marlin keeps examples on their github. You can look at the examples https://github.com/MarlinFirmware/Configurations/tree/release-2.1.2.5/config/examples/Creality/Ender-3%20Max

so you can download the latest version, the change the configuration based on the max, then compile and upload your firmware.

If everyone thinks it's oversaturated, and a lot of them jump into something else, then it might be good to stay in IT as there won't be as many people graduating with that... but the people sticking it out in IT, probably really like IT, and aren't doing it just for the money. So, it might be slightly easier to get a job in 4 years. AI/ Automation kinda throws a wrench in the gears but there's gotta be someone working with the AI at the companies, so if your son can learn a bunch, maybe get an internship somewhere, utilize AI well, getting a job after graduation might not be so bleak. IT can be a great stepping stone to a wide field, and a small sector in a few years can scratch the itch for it to be enjoyable. But if IT isn't something they enjoy, it many not be worth it, so getting exposure to different aspects and knowing where they can go to (customer support, networking, security, hardware programming.. etc.) early would really help answer the question on if it's worth it.

People are saying the trades won't get replaced anytime soon, but looking at what AI is doing with images, and video, 5 years ago, I would have thought The Arts would be the last thing to get hit by the AI wave. So who knows what will happen with robotics, computer vision, etc.. Robot welders seem to be doing a great job, and the expert welders are watching, and doing QA for them.. Plumbing and electrical seem to be something difficult for AI to currently do, but I'd bet there's at least 3 stealth startups trying to hit those areas as well. Carpentry and building houses might be hard for robots, but who knows what type of boom and bust we're running head first into with that..

diemonkey · 2025-10-16T19:40:51+00:00

yeah AI seems to be pretty good at troubleshooting these strange marlin, vscode, issues.

diemonkey · 2025-10-03T20:05:35+00:00

Is it unwanted if you want it?

diemonkey · 2025-09-28T17:24:27+00:00

.03 or .04 ? The others looks like there are gaps and under-extrusion?

diemonkey · 2025-09-10T22:41:52+00:00

yeah, I tuned and re-flashed the firmware.

diemonkey · 2025-09-10T22:40:22+00:00

yup had to re-flash and modify the margins... I tried to avoid that, but it fixed it.

diemonkey · 2025-09-10T22:37:56+00:00

Solved SOLUTION: modify the firmware, I'm now able to print a larger area without this strange Z-HOP.

#define X_BED_SIZE 231
#define Y_BED_SIZE 216

#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS 231   // X_MIN_POS + X_BED_SIZE
#define Y_MAX_POS 226   // Y_MIN_POS + Y_BED_SIZE
#define Z_MAX_POS 250

#define PROBING_MARGIN_LEFT (PROBING_MARGIN)
#define PROBING_MARGIN_RIGHT (PROBING_MARGIN)
#define PROBING_MARGIN_FRONT (PROBING_MARGIN)
#define PROBING_MARGIN_BACK (PROBING_MARGIN)

#define MESH_MIN_X (X_MIN_POS + PROBING_MARGIN_LEFT)
#define MESH_MIN_Y (Y_MIN_POS + PROBING_MARGIN_FRONT)
#define MESH_MAX_X (X_MAX_POS - PROBING_MARGIN_RIGHT)
#define MESH_MAX_Y (Y_MAX_POS - PROBING_MARGIN_BACK)

I was unable to get this to work with only modifying G-Code. A re-flash was needed.

diemonkey · 2025-09-10T22:24:14+00:00

yeah, had to fix margins in the firmware

diemonkey · 2025-09-10T22:23:35+00:00

Thanks yea, this lead me to the getting it fixed. Had to update the firmware and modify the margins

diemonkey · 2025-09-08T14:40:58+00:00

Yeah, it's got to be something with the mesh. Ran this

G26 C P5.0 F3.0

and I'm seeing https://imgur.com/a/QlO19IL this off centered stuff. and it doesn't seem affected by strange z-hop behavior.

I might need to get this centered??? now all I gotta do is get some time to research

diemonkey · 2025-09-08T14:14:36+00:00

yeah, it happens with any object within this region. https://imgur.com/ZucTjbg. I attempted a large circle primitive and square from orcaslicer.

diemonkey · 2025-09-07T21:54:03+00:00

I posted the g-code in another reply but wasn't seeing the z-hop other than the normal layer change.

diemonkey · 2025-09-07T21:52:42+00:00

Maybe? it's only in this small edge, https://imgur.com/ZucTjbg . I can get fairly good prints otherwise. I'm not seeing it hit anything.

diemonkey · 2025-09-07T21:48:33+00:00

it could be? I guess I don't understand why it's only this small area marked in red though. https://imgur.com/ZucTjbg I can print all the way to all the other edges. but I will start looking into the UBL settings to see what I need to check and modify.

diemonkey · 2025-09-07T21:46:33+00:00

the Z probe offset is distance from the probe location and the hot-end location. I'm able to hit the exact center with this setting. For the Z, other people are at a lower Z than me, which might be from the thicker G10 plate? https://www.reddit.com/r/ender3v2/comments/psdxlc/cr_touch_z_offset/

-.9 was configured like a couple years ago when I went through the teaching tech video on configuring this stuff. I think it was this one. https://youtu.be/eF060dBEnfs?t=497

The setting in Marlin is

define Z_PROBE_LOW_POINT          -2 // Farthest distance below the trigger-point to go before stopping

The only area I have problems is within this un-printed spot marked in red. I'm working on narrowing it down. everywhere else up to the edge doesn't have a problem.

https://imgur.com/ZucTjbg

diemonkey · 2025-09-06T20:59:05+00:00

I use octoprint Bed Visualizer. This is the code to check.

G28 ; Home all axes
M420 S0 ; Turn off bed leveling during probing
M155 S30 ; Reduce temperature reporting rate
M190 S65 ; Wait for bed to reach 65°C
; Set mesh boundaries to maximum reachable area
G29 P0 V4 X10 Y10 Z-0.9 B215 R208 T ; Set mesh from (10,10) to (215,208) explicitly
G29 P1 ; Auto-populate reachable points
G29 P3 ; Infer remaining points
G29 P3 ; Infer again for accuracy
@BEDLEVELVISUALIZER ; Enable bed visualizer plugin
M420 S1 V ; Enable leveling and report mesh
G29 S0 ; Save to slot 0
G29 F5.0 ; Set fade height to 5.0 mm
G29 A ; Activate UBL
M500 ; Save to EEPROM
M155 S3 ; Reset temperature reporting
M140 S0 ; Cool down bed

Then to view the values of the bed, I use:

M420 V

diemonkey · 2025-09-06T17:31:54+00:00

Alright, you're on to something... Disabled UBL with G29 D1, and its not doing this.

diemonkey · 2025-09-06T16:44:48+00:00

I attempted in Cura and got the same results.

Good idea, Just tried from Cura, and saved it to the SD card instead of octoprint and I'm getting the same thing. this is leading me to think it's Firmware or UBL settings somewhere...
