Drat - missed this post again. Well, now it is on "Notify" ...

Got the upgrades installed!





Hard to see, but the arduino mega is hiding down there

Printing again, this time I am attempting to make a Herringbone gear set, and push my printer's accuracy with a layer height of only 0.15mm!

[Reply #18 on:]

I really like the upgrades you do to your machine. They are a great improvement to the original. I would love to have such a machine, but at the moment I don't have the space for it.

Printing again... This time I will try to print a sensor bumper for my WiFi Tank 2.0, but the print is tricky... It is long and thin, I am doing a 0.15mm layer height, there are two 45 degree over hangs, and in those overhang there are a hole for an IR proximity sensor... This will not be easy, but I hope it will work

Looks good so far... (yes, finally, seeing it) ... the overhang looks good, too. Did you "just" use the standard converter otr have you manually tweaked the Gcode to better cope with overhang?

I am not going to manually tweak the gcode

For this bumper it is a 5.068 megabyte text file, with 134950 lines of code...

But the latest upgrades to my printer changed everything, prints are so accurate, no backlash or anything, and retract on the filament also works because of the gear I printed myself.

And here is the result...



Ping sensor in the front, and IR proximity sensors on each side on a 45 degree angle

And mounted

Where did you get the kit from, and for how much?

[Reply #23 on:]

What kit? the rover or printer? The printer is made out of multiple things, and is not from one complete kit.

[Reply #24 on:]

Did you only print out a bumper (not the entire chassis)? BTW, the black and white hugging/kissing figurines are cute.

Yes, I only printed the bumper

Just explained to my nine year old daughter what "that thing I'm watching" is, I'm pretty sure she will now be insisting that I build a 3D printer to fabricate toys for her on demand.  Hmm.  Not quite that easy, but I like the sentiment....

Don't show her this:

Or maybe do? I'm uncertain of the wisdom of letting a child make their own toys. Certainly, both up- and down-sides to that.

Printing again.

I'm curious - what do you use for part designing to print on your reprap? Was there a large learning curve (for part design)?

I've thought about at some point getting a set of printed components and assembling my own printer (I've also given thought to a RepStrap); right now I don't have the time, space, or need, though. Part of my reluctance, though, is the "learning curve" for designing 3D parts - I'm not sure whether I want or need to take such a step yet, but your designs and such (especially the cat feeder) make me see that it might be worth it, even if it takes some time.

I am using Autodesk Inventor, but that is because I also used it during my education and also a bit at work, so it was something I already knew.

There are many other options out there though, the one most reprappers use, is openscad, but it is code based, where you write everything, and it got a pretty steep learning curve.
