I am printing JD Humanoid but I noticed a lot of the parts don't have supports. Example servo connectors start about 3mm off the ground, the top of his feet don't print well upside up or upside down. Has anyone created a modified version of JD Humanoid (and other bots) with supports that are optimized for 3D printing.
What slicer are you using?
Type of filament?
Judging from your photo of the part you are over extruding. This means too much filament is being pushed through the nozzle. It is an easy adjustment in the slicer.
You may also be printing too hot and too fast.
Once you have the settings right the part will come out cleaner and supports will separate easily.
Here is link that will surely help.

thanks for the link will have a read and play

There are adhesion sheets available on a different page.
PEI will make a world of difference. 65c for PLA and 100C for ABS.
ABS for taller prints may need an enclosure. Doesn't need to be pretty just something to stop drafts. Even a cardboard box or something similar works wonders.
50% infill will cause warping too as it will cool at different speeds for the interior to the exterior. 15-20 % is all you need if you have a thicker exterior, say 3-4 perimeters.
I am hoping the 140c for the printhead is a typo. Should be 220-240 c for abs and 200ish c for PLA
I would also suggest getting Simplfy 3D which supports about every 3d printer on the market. Super fast slicer and I feel prints look better than with stock software for the printers. Simplfy has a superior support generation that creates easy removal and very little post clean up.
I have a similar printer to you. You will do well to print some calibration cubes and calibrate that printer. You can download them from Thingiverse.
I also use Simplify3D. I could not get the supports to work wit any other software. I have trouble with ABS and most of my prints are with PLA. The supplier of your filament is important as well. I use Hatchbox. I have problems with other brands. They can be fickle.
To answer your original question here is a part with supports generated by the slicer software. They are the darker orange feature. They are peeled away after the print is complete.
@Perry_S trying the calibration cubes now, Unfortunately I am going to have to hold off on the Simplify3D software (already in the dog house with my recent purchases that just turned up on the last credit card bill and now I need some more parts :-)
@fxrtst I have never heard of PETG, I will take a look at it when I run low on ABS. Looks like it is more durable than ABS when reading the info on the web so maybe ideal for robotics.
@DJ you have a really great community here. I appreciate all the help getting started.
I still use Repetier for my print server.
When my credit cards cool down, I will probably buy another one so I can have spare parts in future and speed up printing times.

If anyone else wants I will add a package when I am finished to Thingiverse
Thing is, the end goal is to not have to do that. So you are kinda shooting yourself in the foot.
Take the time to figure out your printer (the one I have) and work on the end goal. IT will be easy with a bit of patience.
A nice experiment might be to propose a part to print and a few of us can slice it for you and show you how we would do it.

Perhaps others who have 3D printed JD humanoid's can share experiences.
@fxrtst I also just started to print in ABS, had to realize that warping is much heavier than PLA, and I noticed the smell of it is quiet heavy! I will try PETG next!
I switched to ABS because I noticed that PLA bends after some time, so I figured it is no use for robotics, but one thing that occurred to me was that ABS cracks really easy when I got the slots for my screws just a bit to tight...PLA was more forgiving on that part! *stress*
Nice you guys mentioned your favorite brands...I am always having a hard time deciding what to buy, availability is a factor too I guess.
I'll enclose the .stl for the dowels.
