frechettemj replied to frechettemj's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAdded a Liebherr-style V-Frame. This allows the suspended ballast to be moved back and forth in order to move the center of gravity to compensate for changing the angle of the main boom. It allows me to move the suspended ballast back 25 studs from the fully retracted position to the fully extended position. I also moved the main hoist to one of the winches located in the superstructure, and correctly routed the string to more correctly reflect a real crane of this scale. Enjoy! This is it's current configuration.

frechettemj replied to imurvai's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI have this exact problem. I have a Samsung Galaxy S22+ and I'm using a a Steelseries Stratus Duo controller. BC2 version 3.2

frechettemj replied to gvo25's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingLooks good! Do the shock absorbers work well to keep the boom from falling backwards?

frechettemj replied to frechettemj's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI've been tinkering with my crane over the past few nights. I added back the derrick mast and suspended ballast tray. There's 3 pounds of weight in the Liebherr 9800 bucket, 2 pounds in the counterweight, and 2 more in the suspended ballast tray. The ballast tray can be lifted off of the ground by the two long actuators mounted on the top of the derrick mast. I redesigned the attachment of the boom hoist to make it more realistic. The boom foot and attachment has been modified to allow the main boom to be lowered to below horizontal, in order to add realisim.

frechettemj replied to frechettemj's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHere's it in an earlier version. It's about 7 feet tall in this configuration. The version in my original post is still capable of this configuration but it's really not the most convenient way to display the model. The crane is able to self-erect in this configuration, with the appropriate amount of counterweight.

frechettemj replied to frechettemj's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThanks!! Thanks! My plan going in was to focus primarily on playability, but I tried to make it as realistic looking as possible. I will admit that I copied the cab design from the 42042, but I added the cab tilt. I have had the main winch run off of the second winch in the body of the crane, but I've found it a whole lot easier to have the winches accessible to make it easier to rig the string for the hooks. The foot of the boom was originally a normal triangle, but I modified so that the boom could lower to (nearly) horizontal. It was easier to modify the boom than to redesign the area around where it attached to the main body. I honestly have no idea.

I've created a Liebherr inspired crawler crane. I designed it with more of a focus on playability, over trying to create an exact copy of any particular model. It's 5 feet tall to the tip of the jib boom, and 4 feet to the main winch. It's fully RC, powered by a combination of Control+ and Power Functions. There's a Control+ hub in the base, and a Buwizz3 in the main body, all controlled by the BrickController2 app and a gamepad. The base is powered by a Control+ hub with XL motors driving the tracks and an L motor for slewing The base was built with multiple 5x7 panels stacked side by side to create a base that would be stiff enough to not flex under the weight of the crane in addition to any counterweight that I added. Here's the base with 10 lbs of lead weights stacked on top. There's almost no flex across the frame. The tracks are detachable, and are geared down enough to allow the crane to move and turn on hard surfaces. The counterweights contain 1 lb lead diving weights, and more can be added if needed. Enjoy!

frechettemj replied to gvo25's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingRight. My crane is loosely inspired by one of the larger Liebherrs.

frechettemj replied to gvo25's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingIndeed. Just offering an example.

frechettemj replied to gvo25's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHere's what I've got for tracks. They're geared way down, so it'll drive and turn on carpet. 20220325_223415 by Matthew Frechette, on Flickr

frechettemj replied to imurvai's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingIt means that the battery is low.

frechettemj replied to Jim's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingThe speed function does not work with mine either. I have a 3.0 and the latest version of the Android app.

frechettemj replied to Jim's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI'm experiencing the same problem.
-
frechettemj replied to Jim's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingIn theory, could the Power Function output on the Buwizz 3.0 be used to power an Sbrick? I'm building a large crawler crane, and it has two Control Plus motors and three PF motors.

frechettemj replied to Flybum's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale Modelinghttps://rebrickable.com/mocs/MOC-8002/CustomBricks.de/custom-rc-dump-truck/ It started as this model. I've added some modifications along the way, such as the tailgate.

frechettemj replied to Flybum's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingSure, you will just need to follow the steps that I used. Download the A005.SLDPRT from the site I posted, find a site online to convert the file to a .stl, then uploaded it to www.shapeways.com for them to print, or print it on a 3D printer if you have access to one. To be clear, I did not make the bucket myself.

frechettemj replied to Flybum's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale Modelinghttps://grabcad.com/library/rc-excavator-bucket-1 I converted it to a .stl, rescaled to 11 studs wide, then uploaded it to Shapeways to get it printed.

frechettemj replied to Flybum's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingFinally got it finished, and put a proper bucket on it.

frechettemj replied to xsysiek's post in a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling@xsysiek, would you be willing to rescale your LT Bucket to be 11 studs wide? I've recently built @Flybum's Volvo excavator, and I haven't been able to find a bucket that correctly scales to it. I currently have your LT Liebherr Excavator Bucket on it, but it doesn't quite look right. I'd be willing to compensate you for your time.
