Modified Power Wheels

Backstory

Back in 2016, we were about to bring home our new daughter from India. She has been diagnosed with Caudal Regression Syndrome. In her case, she is actually missing her legs. So when we saw that Power Wheels was about to release their new “Wild Thing” model, we thought it would be great for her to be able to play in the yard with the kids. Of course, the price wasn’t great at the time and we ended up forgetting about it.

Delta 3d Printer Build (He3d DLT-180)

So I sold a few other things and ordered the cheapest delta 3d printer kit I could find. It came in and took a bit of learning curve… but that is the point when you get into 3d printing, isn’t it? =)

First off, my stepper motors were wired incorrectly. Thanks to the help of those into he 3d printing community, I found I could just play with the wiring till I found out what worked. It did help that I had my little tessel board already programmed to play with a stepper.

Once I got the wiring corrected the motors were still extremely loud when moving. Finally a user on reddit mentioned I should check my jumper settings. Jumper settings?! I just assumed the firmware could do all that. Guess not. Of course, the kit I got was missing all the jumpers needed. Between some help from my awesome neighbor and some old computer drives I had laying around and was able to get all that I needed (12 in total). Once those were in, no more shaking and buzzing! Still not done though.

After scouring through the G-Code wiki and reading up on the firmware that I had (micromake) I found the key setting that I really needed to tweak was the z-endstop-offset. Using the “paper test” that many refer to, I was able to home that setting in. Then came the fun of learning how to load filament in this thing.
