Microcan

@storm4710 thanks I also did 50% because of the print time and the amount of filament. I printed the stand as well so now it is complete.

@click thumbs up for the rover.

Controlling servos is easy with almost every microcontroller, if you get the pulse width modulation correct. I have done this in the past with 50 cent microcontrollers. For this demo I used a PSoC (Programmable System on Chip) and implemented an optimised servo control in hardware. This leaves more processing time…[Read more]

I try metal gear servos just to test the difference. I did a complete dissection. I discovered that some full metal gear servos still use a nylon for the first gear. I did not do a full comparison yet for these servos. But the lower cost nylon servos seem to have the best cards.

Great design by a dutch designer (I am proud). I am convinced that this will become a classic like the Gerrit Rietveld chair.

How comfortable is the chair.

Thumb up I like it.

I got the metal gear servos from China. The gray/brown servo with photo is the MG90S metal gear servos and the blue servo is the SG90 with nylon gears.

Unfortunately the servos are quite different. It turn out that almost every dimension of the servo is different. It is not as simple as tweaking some dimensions so I am remaking the same design…[Read more]

Yes I will publish it. I used 4 low cost SG90 servos (nylon gears) in this version. I ordered some MG90 servos (metal gears) but these are still somewhere in transit from China. I like to compare these servos and probably make some little changes to the model so both servos will fit.

Meanwhile I tested if spray paint (Hammerrite) would make the…[Read more]

Thanks Pete. I made it as inspiration for students embedded systems. I saw a youtube video where somebody build a small robot with popsicle sticks, double sided tape and a few servos. I thought that a 3D print would make it resemble more like a real industrial robotarm.

No comments yet, but I made this little robot last week. Because I ran out of filament I printed the robot with lightweight woody filament.

Nice, did you use a displacement map for the wood texture?

@simonhoult Yes it did violate the laws of gravity. 😉 I guess that CEL did a reasonable job here.

It is the standard Robox profile for Woody at fine resolution with maximum fill. All credit goes to CEL, no tweaks. I just loaded the model choose the above settings and hit print.

(I did do the lubrication with the lubricant the came with the printer)

Results from 3Dbenchy print. Not bad at all. Some little errors at the windows and the bow. I don’t know if this is a slicing error a speed error or the filament shrinking and bending up.

Sorry about the focus I used my phone.

It is the regular one. I did not try meshmixer. I always export straight from the CAD program and did not see this warning before.

I decided I let the robox print a 3Dbenchy see what I get at the end of the day.

I get an error when I load the model into Automaker. When I load the model into 123D design nothing seems to be wrong.

@click I have to admit that I found some good prints. You can probably bridge much farther than I though with the correct temperature and speed.

@pete Can you give us some tips to calibrate the Robox so we can get similar results.

@simonhoult
I have to see the first image of a fused filament printer that succeeds to print this window in a straight line. Only laser sintering and SLA printers can do that. The fused filament printer that have a straight window printed the window as a separate part.
