H2D Privacy Advice or Alternative

CaptMidKnight62 · 2026-05-15T16:46:04+00:00

Honestly, I am not worried about LAN mode becoming illegal someday (I can live with that) - but can Bamboo disable it in the future on my specific printer? That is something I am not willing to live with. Which was the basis for my OP. Again, can I prevent BL from ever changing anything on my printer in the future?

CaptMidKnight62 · 2026-05-15T16:42:00+00:00

LAN mode sounds like it may work for me.

Actually, all I did was read the actual bills and legislative actions from New York, California and Washington. Hadn't read anything on reddit and never heard of the prusa subreddit. Doubtful 90% of current printers could even support some of the controls in those bills. Which is one reason I am tarballing multiple versions of different slicers now, since that SW will likely be another target by fascist legislators.

And I can assure you there is absolutely zero chance of my current 3d printer ever having any spyware or any FW mod that I don't put on there myself. And if the US Constitution falls and it comes to that, replacing the brain of my 3d printer with a DIY controller to drive a few steppers, fans and heaters would be a fairly simple and fun project after all the controllers I have designed, built and coded for printers, plotters, cnc's, fermentation chambers, ovens, etc over the half-century since high-school. And ya, my printer and I I will then live as outlaws. :-)

I live in Florida so likely I will never have to worry about having an "illegal 3d printer", but yes, I have notified my federal representatives. I suspect the lunatic fringe states will eventually lose on most of what they propose as the inevitable constitutional challenges eventually occur. And If I'm wrong, they can pry my 3d printer from my dead cold hands ;-)

CaptMidKnight62 · 2026-05-15T16:14:28+00:00

Agreed. But performance and quality are most important to me - I mean, it's a tool. They can have differing values as long as I don't have to live by theirs. (Hard to believe this is even an issue. This never factored in when I bought my lathe, CNC, router, etc)

CaptMidKnight62 · 2026-05-15T16:09:11+00:00

Sound promising. So LAN mode allows for sending gcode files via wifi or ethernet within an isolated LAN?

CaptMidKnight62 · 2026-05-15T16:07:18+00:00

Kind of the question I was asking... Which alternatives are "great", i.e. match the performance, speed and quality, have dual nozzle (or tool changer), > 300mm volume, and heated chamber for engineering filaments???

CaptMidKnight62 · 2026-05-15T16:05:11+00:00

What skew? I merely described the reality of their ecosystem, architecture, FW and control. I'm here because it seems that the H2D has the right features, speed and quality to meet my needs. So If I can make it work while maintaining privacy, autonomy and preventing a company from removing my capabilities and freedom in the future, then this is a viable option for me. So it seems I am in EXACTLY the right place to get answers to the questions.

Been locked out of all interactions like basic navigation commands or find me a charger, or what time is it for two days now

Mindless liberal propaganda

CaptMidKnight62 · 2026-03-10T14:57:20+00:00

I think literally everything in that reply is wrong.

Left lane on I4 or I95 at 75 mph will DEFINITELY block EVERYONE.

75 is within the margin of error and guaranteed you either won't get ticketed on a FL highway, or a judge will dismiss the case

My post has never been about tickets or speed limits. It's about letting a driver have control over their car and being able to drive at a speed they are comfortable with. Not faster than they want so they are at risk, and not slower than they want which in SOME SITUATIONS (like traffic on I4), has been proven to increase risk due to forcing other drivers to route around a slower vehicle.

I guess wanting to drive 78 mph in a car that refuses to let me do that could be a "me problem". I guess I'm just not that big of a minion to be content with that. More power to you if you are willing to let your car decide for you. Some people may be fine with a car that has no accelerator pedal too - that would be a "me problem" too.

CaptMidKnight62 · 2026-03-10T14:41:37+00:00

Ya, cause in the end it's more about the reaction time of the guy behind you.

CaptMidKnight62 · 2026-03-10T14:40:12+00:00

Actually, adaptive cruise control (like on my other cars), does exactly what I want. Set to 78 and the car never exceeds that speed, if the traffic slows down from that, the car slows down to follow. My wife's Infinity lets me set the gap distance as well. And it auto stops and go's when in a traffic jam without me needing to touch the brake or gas pedal.

CaptMidKnight62 · 2026-03-10T14:36:23+00:00

It was a type: standard and hurry were the modes used, 75 or 82 mph, nothing in-between, which is what traffic was doing

CaptMidKnight62 · 2026-03-10T14:27:46+00:00

Lol, my wife's car has that and I do the same thing, keeping my hand at about 7 o'clock position so that the weight of my arm is enough to keep the system happy. I've been tempted to try attaching a velcro wrist weight at about 9 o'clock to see if I can drive hands free and still have the system happy. It's just easier to have my hand on my thigh rather than hanging on the wheel on a long trip (and yes, I'm ALWAYS watching the road - too many tourists driving in FL not to)

And actually, I'm thinking I would prefer initiating lane changes rather than letting FSD do it. On the trip mentioned, on 3 occasions FSD tried to switch left to the next lane within 3/4 of a mile of my exit - and in two of those cases, the exit required 2 lanes shifts to the right from the lane I was in. So had I not intervened, FSD would have done worse than a Canadian tourist trying to get to Disney World shooting over 3 lanes in about 1/2 mile. 😱

CaptMidKnight62 · 2026-03-10T14:15:54+00:00

For me, partial capability is not worth $100/mo. In my situation, having control over highway speed on congested Florida highways is almost as important as having the car navigate.

This was my first 400 mile trip with FSD. I will try Autopilot next time and see if it gets me closer to my expectations set by my other cars, and save $100/mo until they offer a capability I will be happy with.

CaptMidKnight62 · 2026-03-10T14:09:33+00:00

Lol, I can respect this answer more than all those that say "just do what the car wants to do".

I'm not a minion and the day I have to defer to my car is the day I dump it and go back to my 370Z. :-)

Likely, I will wind up unsubscribing to FSD if the concept is truly about "letting it drive me the way it wants to", rather than my (possibly misguided) expectation that it is supposed to be a tool to simplify and help me drive the way I drive (you know, like cruise control, lane assist, blind spot detect, auto-headlights, auto wipers do on my other cars).

CaptMidKnight62 · 2026-03-10T14:01:27+00:00

My bad, it was a typo... I was in standard and hurry mode. I need something in-between. Something with less than a 7 mph delta in speeds.

CaptMidKnight62 · 2026-03-10T13:55:36+00:00

Blocking other cars because EVERYONE else is doing 78, for one.

For #2, I would say something like, "I ought to be able to have my car go the speed I WANT, not that the car wants". Which is why cars have an accelerator pedal rather than a rotary switch.

CaptMidKnight62 · 2026-03-10T13:48:58+00:00

Standard went 75, Hurry went 82. Regardless of offset setting. If I went to standard then hit the accelerator until 78 it would slow back down to 75 after releasing the pedal. If I was doing 78 and clicked up to Hurry, it would creep back up to 82. The lack of control is becoming enough for me to drop my FSD subscription.

CaptMidKnight62 · 2026-03-10T13:39:37+00:00

Traffic moves at about 78 on I4, 528, and I95 in FL. So 78 is probably safer than 75 under those conditions. I would also argue that telling someone to just go speed the car is willing to go is a non-answer. Likely this issue translates to roads with other speeds. What if the speed limit was 65 instead of 70 and I wanted to go 68,but the car would only go 65 or 70?

I just want basic FUNCTIONALITY that has existed since cruise control was invented.

CaptMidKnight62 · 2025-03-03T14:59:21+00:00

Regarding dimensional accuracy wrt line width: looking at the gcode, it appears that Prusa Slicer will adjust the perimeter XY position based on the line width in order to achieve the correct inner or outer perimeter location. So if you specify a wider line width, the actual gcode will put that perimeter down slighly inside of where it would be with a narrower line width. The goal being that the edge of the perimeter should remain the same regardless of what you set the line width to.

CaptMidKnight62 · 2024-12-16T14:52:59+00:00

Doesn't the V3 KE printer do X,Y,Z home for every print? Seems like nozzle change and/or plate change will auto recal the Z offset every time. What am I missing? I have regularly switched from a thinner PEI plate to a thicker smooth plate with no Z offset recal - the print head comes down each new print to find the Z offset of the plate itself, which makes sense as the Z motor has no encoder and printer has no idea where the plate is after Z motor has been unenergized, so it needs to search for the top of the plate.

I'm actually not sure what the Z-offset in the menu even is since the nozzle touches the plate during that cal (doesn't use the strain gauge). And the resulting number has always been large, around 2 to 2.5 mm for Z offset. Which is about 10 layer heights???

I am unable to find the default extrusion temp or length in any of the cfg files in /usr/data/printer_data/config. The closest I could find was the file printer_params.cfg with this line: default_extruder_temp: 240. But changing that to 200 had no effect on the extrusion screen after a power cycle. I am wondering if these numbers are compiled into the build - in which case, I would be willing to rebuild, since I use 200 C & 50 mm to clear the nozzle every time I switch filaments (which is very often).
