💬 OT 3D printers...who has one?

[Mr_Roboto]

Well, got this biatch going. Finally. I don't have a display yet and one of the temp sensors isn't working (suspect I need to specify the bed sensor in the calibration) but I do have Marlin 1.1 on my Melzi board instead of Repetier .91 which doesn't have melt down protection. A few helpful hints along the way:
-Avoid the TinyUSB programmers like the plague. They're designed for small sized AVRs and therefore they don't work with even a lower capacity board like this Melzi. I will say the cable was useful. I have 2 now but I think there's components here that can be salvaged for a microprocessor project so I'm not altogether concerned.
-What did work was taking an Arduino Uno and making it into a programmer which is available via the sample sketches. I had the cable from the programmers which I was able to directly connect afterwards.
-The GUI errored out initially because of it not recognizing my printer board as a valid Arduino.
-I had to copy, paste and modify the command from the Arduino GUI to put the boot loader on the board. I ran it in the Windows Command Prompt with the -F flag. I had to go into the Ardunio directory to run the command its self, delete out the path that was explicitly listed for execution and add double quotes ("") around the path of the file I was flashing to it as the boot loader.
-After the boot loader was on the Melzi board it was simply a matter of plugging it in via USB, building code then flashing it up.

Just curious but did you try Bossa?

Just put in an order of some atomic filament. Clear and red PETG and a roll of black ABS to play with

 

[Mr_Roboto]

You ever done petg before? am tempted.

Yes, its stickier then pla. Usually i can use pla settings but about half speed. Also need to add a little bit more height, since its stickier, you need that little bit extra to let it laydown and stick to itself and not the nozzle.

It also loves absorbing moisture more then pla so have a dry box

Ive used inland and atomic brands. Atomic is much better quality and easier to print but also 10$ more a roll.

 

[Lord Tin Foilhat]

Its worth it to me to spend the extra $10 to get a better product and avoid the headaches

I like the inland pla + though

 

[Bob Kazamakis]

Drying out the inland made it so much easier to print their petg. I’d spend more if atomic is that much better though

Drying out the inland in a dry box for a while made a big difference. The first time was a nightmare.

With atomic I didnt need to dry it right out of the box and feel as though prints are more successful and less stringy.

Do you guys have an Amazon wonder food dehydrator you prefer? Will break down and get one, I've got some copper Hatchbox ABS that I feel like may be shit and am hoping to get it back.

I use this in an ammo can

Got some new stuff to try!

On the roll is inland Glass Light Blue PLA. Pretty cool color.

The new stuff, top to bottom, Atomic Perfect Red PETG, Black MG94 ABS, and Clear PETG

I think you forgot a picture or two?

 

[Bob Kazamakis]

I got my replacement thermistors from gulf coast. Figured I’d get a spare as well. I need to do a PID still, just need to find time.

 

[Lord Tin Foilhat]

I think you forgot a picture or two?

Yup

 

[Bob Kazamakis]

Blue looks cool, curious on the clear. For sure post up some prints with them. I could use a new color for prints for the kid.

 

[MEATeorite]

Just picked up and Ender 3 Pro. Really neat. Im looking forward to making some tap handles for the kegerator next.

 

[Bob Kazamakis]

Stock ender prints give you false hope

My 2 year old loves the little puppy though.

I ended up buying the same glass blue and it’s cool. Printed a unicorn then promptly cut the horn off

Yeah i agree. Ive only made a few tiny things.

I did some how get it to print with a silver sheen compared to my other blue print with the same filament

 

[Bob Kazamakis]

My picture is a bit darker than it looks IRL.

I’ll probably only use it for stuff my daughter wants.

Side note, I’ve never printed with white before, I dig it. It’ll be used for a lot of stuff around the house I think, looks better than black.

Last week I did some enclosure improvements and other mods.

I doubled the size of my enclosure for the second printer, added a hinge set, eliminated the angles to hold it together and a few things I am probably forgetting.



My new heater is a 250w heat lamp. I may add a second depending on how my results look.




I changed the springs which is supposedly a common weakness on ender3 printers. This is heavily based so I figured why not. The old ones seem fine and will probably hit my tronxy since they are just generic springs.


I got the metal knobs with the springs, I think this is cosmetic at least until I try to crank the temperature.

I did the tape mod on my USB connector. I think I may have shorted my port out. I will do something else next time probably.



My test print came out well. I need to do some tweaks on the slicing.



heater+bed gets me over 40c. not bad, I may add heat and insulation but early tests show big gains over even 35c.

 

[DEEZUZ]

Anybody want to try to make a few of these for me?

I can send one to sample

 

[Bob Kazamakis]

In plastic?

 

[DEEZUZ]

In plastic?

That what they are

 

[Lord Tin Foilhat]

Send dimensions DEEZUZ

Doesnt need to be pretty, rough diagram with measurements in mm preferably
