[@lowtus7]

What would be cool is adding a shaker motor that vibrates the table and flattens the sand between designs.

[@Mrcaffinebean]

Totally agree, but it would be noisy and you would need the ability to lock the ball away while shaking, otherwise it will likely pop off the magnet.

[@robinchazen159]

Amazing, thank you!! I ordered all the components and some I dismantled from my old 3d printer. I’m wondering if could be add a small Arduino Compatible X and Y Axis Joystick Module. Will be fun for my kids to move the ball around 😜

[@DIYMachines]

You're very welcome. 😊 That is a great idea, I'm sure it could be done - I suspect that soon enough someone will fork the code on Github and implement it. It could be as simple as a four way joystick connected to the raspberry Pi which sends the codes as GCODE to GRBL running on the Arduino Uno via the USB serial connection. As it stands you can drive it around manually using the on screen controls in Octoprint.

[@jneilliii]

I know of a USB Keyboard plugin for OctoPrint that may allow for using a USB number pad for direction control.

[@markstirton1014]

Could you tell us how quiet these tables are. I'm going to order all the parts next week. Excellent videos

[@DIYMachines]

I think it is very quiet - everything in my living room must be off and no-one talking to be able to hear it. I was very concerned with volume whilst designing it and took measures (such as the faux leather and Trinamic stepper drivers) to minimise noise.

[@LucR777]

Sorry for the necro-post. I really enjoyed your video and this project, and I'm trying to replicate parts of this project, but had a few questions. First, why is an auxiliary Arduino nano used for the lighting? Wouldn't it be possible to also run that off the UNO? Second, is a Raspberry Pi truly necessary? It appears to be mostly for user convenience, and pattern drawing. I will only need to move the stage to an xy coordinate every so often, so wouldn't interfacing with the UNO directly also be possible? Third, how fast are you able to run those motors with the friction and slop from the rails? I'm trying to recreate the stage as thin as possible, and was wondering if I could use lower profile but also lower torque / rpm steppers instead. I also won't be running the stage continuously, but in rapid bursts lasting just a few seconds. Lastly, thanks again for the great video. This isn't a question, just wanted to really emphasize how great you and your projects are. Keep up the fantastic work.

[@netherfred]

Apart from the time invested and without tools, how much money would you say you need to invest to get this project going if you start from scratch? Around £200?

[@DIYMachines]

Yes, including buying the wood and linear rails I would say around £180. I bought very strong toughened glass for my table top at that cost around £90, though you could opt for acrylic instead which should be cheaper.

[@mintgardener]

@@DIYMachines meanwhile it’s costing me like $570 🥲

Wow, such an amazing project. Thank you that you share it with us. But there is one question. Is the Bug Converter powerfull enough to handle the LEDs and the Arduino for a longer time?

[@RicardoAbinader-t4r]

is there any specific type of sand or its just normal sea sand

[@TheChariotdriver]

Enjoyed these videos. I have a round table that I’d like to try to convert to build this project. I’m m assuming that I over build the size to accommodate the entire circle footprint and then restrict the print size in the software so that it knows to only print patters of 500mm diameter. Anyone do this for a round table!

[@guywhoknows]

You need to make sure stick pads are used on the glass or it could be knocked off and make sure. Tempered glass is ordered.

[@DIYMachines]

Good advice, I did use tempered glass in my project - but will add some sticky pads. :)

[@evanquinn1338]

How would you go about doing it with a round table? How could you reduce the amount of empty space where your railing system cannot reach?

Hello, I'm an student that is very interested on your project, and I wanted to build that, but in a minor scale.

Thank you so much, keep sharing projects, this is so valuable.

Of course it can be, I guess there are values specificaly defining the size. But I guess you would have to take a look into it.

What kind of 3D printer do you think would be sufficient to print the parts required for this build? Does it have to be big or fit a particular criteria? Thank you!

[@DIYMachines]

I used my Prusa i3 Mk3 but a Prusa Mini would be capable. The largest printed parts foot print is about 150mm along, and I printed all my parts in PLA. None of the parts are 'tricky' prints either. I do rate the Prusa printers if you were thinking of buying one, they are a little more money but are feature rich and their support is brilliant if you ever need it.

[@jimfrankfort]

Very nice project and well done! I have a question about "marble wobble". A small team at our MakerSpace is building a kinetic sand table and the steel marble is not moving very smoothly through the sand. There is good magnetic connection with the steel marble and the mechanism is moving smoothly. The steel marble draws a smooth line but it has minor variations in speed and appears a bit "herky jerky" I've looked at a bunch of video's of different sand tables and can't tell if the same behavior is going on with them. I did see a lower cost commercial kinetic sand table its marble moves like ours. Sooooooo, does your table's marble move smoothly, and if so, do you have any suggestions as to how to smooth the movement of the marble? We have tried different sized marbles and the larger ones are smoother. There is ~2 mm gap between magnet top and sand table, with roller bearings maintaining a constant distance. Thanks!

[@TheChariotdriver]

I’m considering building one of these tables and thought of the issue you are referring to. I’ve seen other videos on YT where they too differ from the marble jerking. I had thought about attempting to suspend the marble magnetically just above the table top, but still in the sand. I think there’s a way to make the magnet ball bearing “float” at a specific height so that the constant jerking doesn’t happen. Wondering what your thoughts are about doing this.

[@JaakkoF]

One solution is less magnetic force to act on the ball. If the magnet is strong, it tries to pull the ball tightly against the table and any sand particles will make it brake and thus jerk around.

[@TheChariotdriver]

@@JaakkoF thanks for your reply. I purchased a powered device that suspends a metal ball in the air just an inch or so above its base. While I haven’t had the time to make a prototype yet I was thinking a z axis input from a old 3D printer could actually “lift” the ball bearing up and out of the sand to move to new coordinates and then drop back down where needed to start the next line of the print. This could change the designs that are capable since it’s not a continuous line being drawn. But doing it is the difficult part.

[@RonMyers-b8q]

I am having two issues with the sand table that I have built according to your instructions. The LED speed potentiometer is working backwards. If you turn the knob to the right (up), it slows the lights down. If you turn it to the left (down), it speeds up the lights. I've checked the wiring multiple times and can't see anything wrong. Any ideas where I should check to fix it? Secondly, Everything works perfect when tested separately. All control buttons works for the lights, the gantry works great, and it will run a pattern. This issue is when I run it all together, the pattern button will not change patterns. It stays on the default rainbow pattern. But is I unplug the Pi and just run the LED lights, they work perfectly. Any ideas what I should check to get this fixed? Thanks

[@charlesdemey3929]

I had the same issue. So I basically set the 0 value to the max and then everything went inversely (correct direction). But then I had the issue that the peak speed would be somewhere in the middle of the rotation so I just adjusted the range of values for that variable. This is the edited loop with only the speed function (sorry about weird KZbin formatting): void loop() { tableSurfaceLEDs.service(); unsigned long check_time = millis(); if (check_time - last_check_time > 200){ // If checks come faster than 300ms, assume it's a bounce and ignore // read the input on the potentiometer to determine the requested brightness for the LEDs totalBrightness = totalBrightness - readingsBrightness[readBrightnessIndex]; // subtract the last Brightness reading: readingsBrightness[readBrightnessIndex] = analogRead(inputBrightnessPin); // read from the Brightness sensor: totalBrightness = totalBrightness + readingsBrightness[readBrightnessIndex]; // add the reading to the total: readBrightnessIndex = readBrightnessIndex + 1; // advance to the next position in the array: if (readBrightnessIndex >= numReadings) { // if we're at the end of the array... readBrightnessIndex = 0; // ...wrap around to the beginning: } averageBrightness = totalBrightness / numReadings; // calculate the average: int ledValueBrightness = map(averageBrightness, -47, 900, 0, maximumBrightnesAllowed); // Map the brightness value to range of LEDs Serial.print("Brightness of LEDs is set to "); Serial.println(ledValueBrightness); tableSurfaceLEDs.setBrightness(ledValueBrightness); //set the table LEDs brightness value int potValueSpeed = analogRead(potSpeed); // read the input on analog pin 2 to determine the speed for the LED patterns long ledValueSpeed = map(potValueSpeed, 0, 1100, 0, 10000); // read the input on the potentiometer to determine the requested speed for the LEDs Serial.print("Speed of LED pattern set to "); Serial.println(ledValueSpeed); tableSurfaceLEDs.setSpeed(9300 -ledValueSpeed); //set the table LEDs pattern speed last_check_time = check_time; } }

I would love the ball to have sort of a mind of its own. Meaning if it is lazy it Just rolls a little slower but sometimes it gets energybursts and races through the Sand. Also the ball should be able to get scared when there is a loud noise detected. Which then frightens the ball so it moves from its path and stays in a state of shock for 5-10 seconds and then slowly creeps back onto its path and continues. Is Something like that achievable?

[@vuphan8474]

@@nf794 I am beginner in coding and I'm pretty sure it is possible to do. First of all with your idea, in order to the achieve the effect of scaring when detecting noise, there'll be a concerned with electronic modules - noise sensor in particular, then you have to have code that work with noise sensor, from that you'd create a sequece of movement that show the ball's scaring mode. Beside all that, then there'd be steps where you'd have to insert your code into his where you gotta make it works inside his everything. So yea if 1 is easy in your scale, I would rate its about 8-9 in order for you to achieve what you want. But if just do exaclty what he guide, I would say maybe 5? since I think he pretty much publish everything and all we have to do is just get the parts and assemble them all together, even the code.

[@robjennings3045]

It is a nice looking project, but what is the point of a Pi board? it really seem like overkill to install a full linux distro with a 3d printer server just to talk to the arduino. Up the size of the arduino board to something like an 8266 or ESP32 with an SD card and you can do everything on that. not much code to get it to read gerber files off SD card in random order and 'print them' directly. Control buttons and WS2812 can be connected to that and whole thing would burn a lot less power and could still provide a web interface to interact with table or manage contents of SD card

[@TMRu22311]
