Sweet layout. Wonder what track length on full layout? Looks like it can be run in several different configurations. Maybe a private motorsports club for high rollers?

I’ve been working a lot lately with printing light diffusion materials, transparent filaments, and layering. This is the final prototype on my nametag design. It took a bit of work to get the technique down, as well as form factor and weight to minimum. I’ve also embedded NFC tag in it, so when you hold a cellphone up to it, it takes you to the business website.

I’m using a transparent holographic cut vinyl underlay; the background actually changes color depending on the viewing angle. It also makes for numerous custom color options.

I’m thinking this could evolve to a design for a lighted Goblin license plate frame, or even a backlit logo inlay anywhere else on the car.

This design carries over to application of industrial polymers and vinyls that would be UV resistant and very resilient in an automotive application.

Very Cool! That would be an awesome name tag to wear at a sales convention or trade show. It would certainly grab the attention of passersby.

Be sure to let us know if this is something you are going to make available to the general public. I have guys at trade shows several times every year. I'd be interested!

I’ve trialed it at a local small business group meet up, and its proven to be super effective, lol. The complexity of manufacture also keeps me from ever needing a patent.

I have the procedural manufacturing process ironed out to where I can produce enough volume to satisfy demand.

I plan to print the final production case assembly from nylon carbon fiber, which I have not prototyped yet. These won’t be cheap (due to need for CAD logo design time), but they will carry a full lifetime warranty. Either way its a business write-off for the purchaser. I’ll keep you posted.

I am in the middle of trying to get all of my filaments into sealed containers, in order to avoid any potential for humidity to affect the more hygroscopic filaments. With that involves printing 30 roller assemblies
for the filament spools.

My 5Pro has been underextruding and printing like **** lately. I got up this morning and rechecked the extruder steps… Was back to factory settings. I guess the eprom got dumped at some point.

I decided to just bite the bullet and figure out how to write my own firmware. I got that figured out in a couple of hours. I loaded the firmware, and still was having problems with the bed level sensor not being recognized. This is where you gotta start becoming an internet sleuth, and using deductive reasoning. If it is not a common problem on the internet, you need to start looking at other causes.

Was not an entirely common issue, but I figured out that the mainboard version of my printer was in between some bed level sensor transitions, and it was not wired in a way this firmware was set up. I re-wired the BL sensor to current specs, and voila; worked great.

I’m now printing reliably within 1/10th of a mm in all three axis, as well as walls. I upped my extruder max temp in this new firmware, so I will also be able to start printing carbon fiber nylon parts. I plan to print all of the Goblin parts I design from Carbon fiber nylon from here on out.

@Brian74 Take a look at Klipper if you haven't already. Klipper allows you to offload the processing from your main board to the device you're using (I use an Intel NUC). In many cases that's going from 8bits to 64 which is huge - no longer missing steps! It also has the added benefit of easy firmware flashing and just about all of the flexibility that Marlin and other firmwares have. It's been a valuable upgrade in many ways beyond what's mentioned above for my printing.

If it looks good, install it with kiauh as it's a pain to do any other way.
