Without a doubt the goofiest looking machine I have ever seen.  Seems to work though, at least with a pen.

Hopefully I'm wrong, but when you add the extruder head and filament attachment, I can't imagine it holding stable at the speed you were drawing with.  Seems like it would clank and bang all over the place.  That is a lot of momentum hanging out there on just six little arms.  I think while you are still working on leveling the bed and using a pen, I would attach an equal ounce weight of the extruder head to the mount point and just solid mount your filament line, then try some more runs with that extra baggage and see how it does.

Also, how are you planning to compensate the filament line as the head moves around?  Won't you be pushing and pulling on it constantly?

One other thing I just thought of...   If you think you might be doing any jobs longer than an hour, I would definitely consider getting an online UPS to power it.  One little power glitch and ten hours of work (plus materials) would be lost.  I'm using an OptiUPS online UPS with my CNC router.  It also runs my shop computer that drives the whole thing.

I've had the power go out during a print before. :s  I'm thinking about getting a dedicated solar / battery setup for the printers.

Waiting for the video download, not sure I have quicktime on this laptop...

just about everything in my house is on a UPS... lol there everywhere!!!!

at my last job i took apart about 50 of them or so! no joke! they would replace a UPS instead of the battery!!!!!! mainly because they were "old style" lol there just fine... so i have a lot of them i use them everywhere! as serge suppression and those pesky blimps!!!

:) so I'm good there! good idea and i agree everyone should do such thing!!

finally after fighting with the extruder motor for about 5 hrs... ( found i had a setting wrong in my extruder set up in the G code... needed to be absolute)  

i also found that i needed to change the MM_Per_Unit for the extruder motor... i randomly guessed 330 and it was dead on! lol i could not believe it! i haven't measured it yet but its printing really well with the one G code file so... what ever! lol  i can get to the MM_Per_Unit for the extruder right from the lcd menus... so it works grate for tuning on the fly!  

the next day... lol i finally got it to print!!!! yeah!! so Cool!!!!

ok so i drew up a .5x.5x.5 cube in Google sketchup

converted it to stl
sliced it with kisslicer
and printed it from the SD card... no PC at all so far! lol

i still have some tuning on the extruder temps and speeds and all the good stuff but the first print was the best so far!!!! lol don't know why it was the best but it was...
now i cant seem to replicate the quality of the first print! lol

ok so here is the cube.

now i did have some troubles with first 2 layers so this changes the height of the cube so its just shy of the correct measurement...  photos attached with some other fails/stopped prints...

[attachment=3414]
[attachment=3415]
[attachment=3426]
[attachment=3417]

here are some of the finished cubes. you can see the far left is the best... its the first! lol so i dont know why yet... but i cant get that kind of quality again... and now that i know i can get that good its going to drive me nuts! lol

[attachment=3418]

another close up.

[attachment=3419]

some tests that i stopped for whatever...

[attachment=3420]

and yes... i happen to get fantastic stick to the glass ( with some tuning) so the bottom is smooth as can be.

[attachment=3421]

ok so now its time to measure.. how accurate is this built from scratch delta prototype 3D printer...

this is with 0 clean up! none at all...

.5x.5x.5 cube...

side 1-3 , side to side  ( small amount of build up on the one side where it started every time, that's normal... )

[attachment=3422]

side 2-4 , side to side

[attachment=3423]

side 5-6 , top to bottom ( lost some layers due to the head being too close to the glass...)

[attachment=3424]

lol holly crap i could not ask for better results!!!! lol

and now for those who fallow my work closely... a sneak peek of whats to come with my videos of finished objects ill be making...  :)

( ignore the background audio! lol)

17 min in 17 seconds...

 [attachment=3425]

!!! ah! yeah!!! now i can make my final "report" video! :)

still some tuning and figuring out to do... but its printing!!!

thanks for all the support and help guys!

Awesome! One more RepRap is born. :D  It's kind of nice to watch it print with a stationary bed.:cool:

The third cube looks like the nozzle wasn't extruding as much as it should.  I've had this happen when the hobbed bolt gets plugged up with plastic.  Another thing to check is to make sure the gear on the extruder stepper motor isn't slipping.  Another thing that could cause that is too low of temperature on the extruder.  The 4th one looks like it extrudes too much in some spots?  I'm wondering if the bowden tube is binding up and releasing the filament with more force than normal.

Thanks guys! Here is some playing... All 1/2" tall the "~Russ" is 1/8" thick prented on its back (flat)
The R was prented standing up vertically with 0 supports. Too cool!

Sorry for the separate posts. Each a separate attachment...

Awesome Russ :cool: next thing ya will know 4 days will have past and realizing you might have a 3D printer "problem". :D
 Not sure where I'd get that idea :s I don't have a problem.. who said I had a problem. :dodgy: Kidding! :):P

thanks for the feed back Nate...

yeah i was playing with the MM_Unit on the extruder motor on theses so that was most of it...

once i get it calibrated better ill have you look at it again for troubles ! you have that printer problem that gave you a good eye! lol

also, the extruder is direct drive... ?? so the gears cant slip?

unless you ment the the hobbed gear... jeff maid by hand... its its so sharp its Crazy! lol i cleaned it up a bit so it would have less chance to chop off plastic bits... i did however order an MK7 hobbed gear to try if i want to later.

the ptfe tube is kinda bouncing around and i plan on attaching a support for it... rubber band it to the top or something to hold it steady.

thanks for the feed back! its so cool watching this stuff print.

what MM/S are you normality printing at?

This seems to be good at 4 mm/s for the first layer and 10-15 for the rest. its slow but that's because i haven't figured out the limitations yet or what the extruder can handle. i think if i speed up the mm/s of E it will work at faster speeds.

this is a .5mm extruder with 1.75.. abs...

so i was running at 4mm/ sec and 15 mm/sec infill... ok so i left it print at 500% speed!!!!! AHHH! that was a mistake! lol crazy enough it worked! lol check it:

[attachment=3433]
[attachment=3434]

that's 75mm/s infill and 20mm/s perimeter! lol

i think if i could extrude the plastic fast enough it would still work! lol

oh i wish i would have seen it... i walked away for like 2 min and it had this much done all Ready ! lol i stopped it before it ripped its self apart! hahaha


you know what... those speeds may not calculate out correctly as that's just what the software stated... hummm...  it may be faster as its triangulated.. ?!?! i have kn ow idea now... hahah  lets just put it this way... the hot end was FLOPING around! hahah

Very good results Russ, this speaks volumes of the skills you have, great work there.:cool::D:P
thanks Jeff!!! thanks for the inspiration and help with the parts you gave me!
Your welcome Russ.:cool::D:P Please post a video on YT of it printing, thanks.
Haha! I was just working on the audio today of the film I'm making! There is alot of stuff in this video from step by step start to finish with time laps and all kinds of good stuff!! ;) hope to get it done this week! Yeah!

Russ did you have to tweak something to energize the hotend and heated printbed? If so, what exactly, thanks.:D:P
"Tweek" are you talking software or hardware?
If I may Russ. I just set up my heated bed. I ran 12V into the 11A input on the ramps and 24V into the 5A input. When I energize the bed the led's on the bed and the ramps board pulse. As they pulse, the backlight on the lcd pulses also and pronterface loses communication with the ramps. If it's working for you, would you mind sharing what YOU did?

Well, that's basically what I am asking. I have not messed with the newer software's or as I do not have a LCD on either of my printers yet. So, if you could enlighten me please, as I have a person with one of my Rostock kits who is asking for help in this way, thanks, Jeff. :D:P

It was Marlin doing PWM because of this. Fixed MY problem.

// This sets the max power delivered to the bed, and replaces the HEATER_BED_DUTY_CYCLE_DIVIDER option.
// all forms of bed control obey this (PID, bang-bang, bang-bang with hysteresis)
// setting this to anything other than 256 enables a form of PWM to the bed just like HEATER_BED_DUTY_CYCLE_DIVIDER did,
// so you shouldn't use it unless you are OK with PWM on your bed.  (see the comment on enabling PIDTEMPBED)
#define MAX_BED_POWER 256 // limits duty cycle to bed; 256=full current ----------------------------------------------was 128 3-17-2013

Jeff, I had to turn it on in the software. In the config file. I will upload the config file I'm using tomarow night. The most important part is the feed rate of the filament. Will add this in to my video. Will add other stuff in my video that will be helpfull.

~Russ

Ps. I added a BIG heat sink to the heated bed MOSFET on the ramps bord. I was afraid it would burn out and it gets hot! On warm up. To maintain the heat it's fine. It's just on warm up!
