Well guys, its gonna be a few days before I am printing again.... managed to destroy two hot ends over the weekend. 1 authentic v6 due to the giant messy clog. and a china knock off that I tried to mock up in its place in the Titan extruder. Looks like i wont be making anymore parts until the v6 lite comes in later this week from Filastruder.
In the mean time, I am gonna catch up on schoolwork, and hope to get to work on programming my arduino Mini for the leg retracts.
What are your R&D costs so far? Seems a worthy effort
@jayinsc Mostly just plastic haha. I've gone through about 3 rolls of PLA @ $20 a piece, and then probably lost about $100 on defective solo parts off of ebay. Should have just gone the new solo route from the beginning.
T-motor 3510's were $45/piece x 4
DJI Inspire props $6 a pack x 2
DJI inspire quick release hub $3 x2
Carbon fiber rod 22x500 $22 x2
Carbon fiber rod 8x250 $17
arduino micro $15
Theres gotta be more things here and there. But then factor in solo
bought solo with gimbal for $300 @best buy
Sold Solo body $60
Sold Motor Pods $90 (total)
Sold props $50
So gained back 200 of 300 from solo.
So Raw materials, probably around $415.
Total project cost including dev material and ebay loss, around $575.
The look on my girlfriends face when this thing flies? Priceless.
Also, just for spits and giggles, I got my printer kinda working with a stripped out knock off hot-end. Somehow it has miraculously chugged through an 8 hour abs print. So we are kinda-sorta back and rolling coal!
I also recently became a 3d Hubs partner, so if anyone needs something printed, or would like to support the endeavor, go here to order : Bearcat Maker's Hub
I can make all kinds of solo accessories listed on thingiverse.
Heres a video of the abs central frame mount. 50% infill. 200 micron resolution.
Maybe if I'm lucky, Ill have my CF tubing from china by friday. It would be sweet to fly this weekend.
Oh crap... those calculation numbers are off.... i neglected the amount of caffeine consumed and the amount of times i had to fix my printers.... lol lets just say closer to $850.
I've got easily 100-150 hours in modeling this project.
Light update for you guys, Got the printer limping again.... until parts come in tomorrow. Heres what it made last night! (it's the nose without a hole in the end!)
Currently printing canopy top updated part.
UPDATE!! Not huge but definitely getting there.
So I've hashed out my plans for the landing gear motor, but have never done my own entire bit of code on arduino, so that should be fun. Planning to start testing this later tonight. Schematic below, let me know what you think.
Also, finally repaired my ABS printer and spent several hours trying to perfect the art of printing ABS Plus from eSun. Only to find out, it needs printed at 255 in order to be happy with layer bonding.
I also figured out that rectilinear is a crappy infill pattern for thin circular parts. So I changed over to the new Prusa version of slic3r, and my cubic infilled arm joints are tough as hell now.
Photo dump. New Canopy printed, Nose printed, upper frame brace printed and servo mounted. Lower frame printed from PLA, going to try and do it out of ABS, but its a 16 hour print.... PLA might have to suffice. Both left and right arm joints are printed in ABS. Now "Trying" to print the outer joints, but they are a nightmare because Slic3r doesn't have a "Touch Bed" only option for support and its killing me.
Hoping to have a full mock up of the frame by Monday, Still waiting on the damn carbon fiber and leadscrew. They;'ve been in California since last Thursday.
Other than that, I need to finish the wires. Measuring is hard because I havent assembled the drone to get a COG yet. Don't want to make the wires too long or too short.
Also have to figure out where to place the Compass so it doesn't suffer interference. Obviously this time there is no leg for it to hide inside.
Also need to print gimbal mount for gopro. But other than that, I think we are in the home stretch. Begging for test flight on Monday!
So with a hope and a prayer, I might be able to test fly next week. Probably not with successful landing gear transforms.... but still, a start.
Here's my to-do list for the next 7 days, if I really want to fly over Easter weekend (we have a waterski tournament, so yeah, I wanna film it.)
1.) finalize transform mechanics, Current link arms are too short and do not allow for proper transformation of the body. (this should be easiliy doable.
1B.) Print them, in sturdy abs.
2.) finalize transform mechanics, at the very least, get endstops installed and wires routed, can be tucked away until after first flight.
3.) Print bottom body Final piece. Last version printed fine, but split because my first layer adhesion was way too good.
4.)print appropriate control am mounts and mounting brackets out of abs.
5.) cut remaining CF tubing to size.
6.)Print gimbal lower, mount to chassis
6.) Assemble airframe with internals installed, find COG.
7.) drill holes in CF tubing, route wires.
8.) pre-flight power test
9.) Pre-flight compass Calibration.
10.) Flight? Maybe? Possibly? We shall see.
Wish me luck!
Good luck! Can't wait to see it in the air
Revised transform mechanics, printing more abs.
Hows the progress going Andrew
Progress halted a bit. The more I thought about the design, this thing is going to be a nightmare to transport anywhere without the high risk of breaking something. Instead I designed a foldable design similar to the Mavic, but with the 350-400mm frame size when unfolded. Currently fixing my heated bed on my printer and then i plan on making that instead. Much more feasible, and the design still allows for 13" props and monster motors!
It's hard to be going down a path and realize it's the wrong direction after the amount of time invested. Kudos for the effort and sharing what was done.
Good luck with your new direction, should be fairly spectacular based on your prior working knowledge.
