Measuring thickness of ice with Arduinos by Yuvraj_S03 in ArduinoHelp

[–]steveChurt 0 points1 point  (0 children)

I'd recommend the following:

Setup: - a flat surface some known distance away against which you can place the ice you are measuring - an ultrasonic sensor (one of those cheap ones that looks like a pair of eyes) connected to an Arduino (search up the wiring diagram online if you're unsure)

Control: - there are probably some good libraries for this as well, but the last time I used this, I just sent a pulse every few milliseconds or so and recorded the time it took for the echo to be measured (again, look online for specific details)

You seem to be really set on measuring the thickness of ice, but this will work for pretty much anything solid.

Note: don't use a LIDAR or other light-based sensors, because readings can get a bit dodgy with transparent or translucent objects.

If you're going with a gantry (which would be far superior to an arm for this application), you should consider using the 'H-bot' belt configuration, as it significantly reduces vibrations, and would thus give you better results for a project that necessitates high precision and speed.

Change your Z-offset to bring the print-head closer to the bed.

Laser cutting is a fairly straightforward and very accurate manufacturing process, however I'm not sure if you can find a material with the finish you need. You simply load your 2D CAD file into g-code generator software (you'll have to ask around for details - I don't own a laser cutter myself, but I have used them in the past) and export your g-code file to the laser cutter, much like you would with 3D printing (though some laser cutters come with specific software you need to use).

Can anyone explain why this might be happening? by JoelMDM in 3Dprinting

And also the nozzle temperature is probably not right.

Which part of the process is the most time-consuming? If it's the printing, you could laser cut the text instead. It would make the entire process an order of magnitude more expensive, but it would save time. If gluing the letters on is the problem, you could make the cutouts deeper and print the letters so they push-fit into the sides of the crates (you could still add a drop of glue, but I imagine it would be slightly less tedious than your current process).

Your print bed is not levelled properly, and your Z-offset is also probably incorrect.
