Most manufacturers say not to take them apart, fyi.

I have found that the best method for me is to use the glue stick on glass then print using a raft, some of the prints I tried still pealed up mid print with just the glue stick and no raft. With the raft every print has worked great.
Thank you ashhhhh for figuring this out.

If you modified the power in the firmware I believe that whenever the hotend is "ON" you are using switching the power on and off really fast to fool the hotend into thinking it is still connected to a lower voltage.
To test this theory change the power the hotend is getting in the firmware and the sound should change pitch. It that is what happens it's fine.

I got small things to stick to the glue stick on glass without problem, haven't had a chance to print anything larger yet.
I also have had good results using a raft and printing onto unheated Masonite.

That is a very nice frog. It's about the size of the green one I printed, measured mie and it's about 5mm tall. The only way I could get the PLA to stick was to squish the first layer into the kapton with the fan on.
What did you use to photograph the frog, those are amazing photos considering how small it is.

fyi, locknuts are single use only. We all use them over and over but they are not designed for that. Sublime has an excellent idea, locktite.

awesome idea to make bigger prints.
If i were to do that and it was 12V i would just use a relay for the beds and use the normal bed output to switch it. No firmware programming and the relay should be @ an autoparts store.

i would ask the supplier about it. There is no reason to get a machine and have hot end problems. There are many good designs out there and if the supplier decided to make there own as it looks like they should stand behind it. Do you know if they recomend pla? Abs is more forgiving to poor hot end designs.

Try setting the bed to atleast 100, heigher if possible and turn off the fan.
Some people have had luck putting a towel over the printer to keep some of the heat in while printing.

It appears that this contest is more about photography, I had a tough time getting this little frog in focus.
Using Kisslicer on my prusa with 0.35 nozzle and translucent green PLA.
; layer_thickness_mm = 0.15
; extrusion_width_mm = 0.38
Not sure if it's the smallest but I though I should enter this little print.

RAMPS 1.4 would be my suggestion because many people including myself have destroyed the pololu stepper drivers and the RAMBo board is the same price but they cant easily be replaced. With the RAMPS 1.4 it's plug and play. I have destroyed 2 of the pololu stepper driver boards at this point one because I was moving the x axis on my prusa back and forth really fast to wear in some PLA bushings an

I have also had success post heating the part. What I do is when the print is over turn the HB to max and put a small cardboard box over the print, after 15 mins or so set the HB to 80C then in another 15mins or so I turn it off but leave the part under the box untill its about room temp. This has helped on a couple parts that I needed to not crack during warming.
But if they are cracking during

I believe so, I thought that was one of the benefits to the ramps 1.4.

The heated bed has a separate pwr in for the heated bed, you should be able to just run the 24v through the ramps without a relay.
I do the oposite, I run 24V for steppers etc. and 12V for heated bed without relays or problems.

I have tested the Garolite (LE) from McMaster Carr and it sticks to well. The first print I did I had the Z height a little to low and the nylon got really squished into the garolite. The warnings posted on taulmans web site are correct, not only will you destroy your part but the top layer of epoxy and cotton stayed attached to the now broken nylon print that is sitting across the room because t

In the search for a good print surface for printing Taulman Nylon I got a sample of Corian ( its used in counter tops and industrial design) from a coworker to try, for the nylon is sucks.
However so far it works awesome for ABS and polycarbonate, both of the test pieces have stayed down flat better than Kapton tape on glass IMHO. I will test using PLA and PVA when I get a chance but wanted to le

I have read that many people have there travel speeds around 250mm/s and that is what I currently run, I assumed that was most people were running at. In the competition section most people are running quick travel speeds from what I remember reading but as cameron pointed out it's possible to get good prints at lower speeds.
Also swich to Kisslicer, Sli3er is not worth the trouble. Read some o

as mentioned above your travel speed is very low @ 130mm/s. I find that travel speeds less than 250mm/s causes blobs even with a bit of retraction.

I just saw that the taulman3D web page has been updated with some more bed materials.
I found a printed circuit board at radio shack that was big enough to give a try but even on a small 0.75 in diameter cylinder the plastic was distorting the circuit board, it did stay down but the thin board did not have enough strength to keep a larger part from deforming the circuit board. Perhaps a thicke

When i first looked at he mk7 i thought that was the direction they were headed in, moving the drive side to side within the plastic drive block.

The site change is a large step back. Yes you are right about the queue, i also used to look at the new things and now that use is destroyed. They also removed the time stamp when objects were made, that was an important feature.
My other problem with the changes is that the pages are more cluttered with stuff that has nothing to do with the page you are on and it now wastes my time w/stuff i don

i have had limited sucess with kapton @ 120C and a raft. I would like to try the circuit board method as the perforations reportedly help hold the print down using a more mechanical method of attachment.
Anyone tried a heigher bed temp?

If you move the stepper very fast, yes. I installed new printed bushings on the extruder carriage and was moving it back and forth by hand and poof. Burned out the pololu.
But i do move them slowly without problem.

do you have a fan on the PEEK insulator? It looks like the transistion is creeping up the filament. I dont have a j-head so just a gess looking at the pic. Good idea to take it apart and have a look.

jamesdanielv is on the right track as far as voltages are concerned, I run 24V and it allows much more headroom as far as how much power you get out of the motors. Sublime can chime in but I believe he specs a higher than 12V power supply for the tantillus.
The pololu drives can take up to 30V, using the same motors, RAMPS, etc and get more performance out of the machine. However you have to cha

they say the max torque of there nema 14 's is 20 oz-in and that is typical of that sized motor frame.
Did i miss something?
Usually the nema 17 's go up to about 60 oz-in but if you want more torque your most likely going to go up in motor size or change another parameter like more voltage.

; extrusion_width_mm = 0.38
; num_loops = 2
; skin_thickness_mm = 0.8
