I don’t expect a 3D printer selling at USD49 in kickstarter (Now at USD99 in their eshop) can provide decent print. However the 28BYJ-48 just can’t do the job. You can find more information about the 28BYJ-48 from <a href="https://grahamwideman.wikispaces.com/Motors-+28BYJ-48+Stepper+motor+notes" rel="nofollow" target="_blank">https://grahamwideman.wikispaces.com/Motors-+28BYJ-48+Stepper+motor+notes</a>.</div>

101hero team knew the problem, instead of using the standard
1/64 reducing ratio motor, they use a special built 1/32 ratio motor to
reduce the steps per mm from 975 to 539. As the torque of the motor will drop
dramatically at high speed, the max speed of 101hero stock motor is 14mm/s. Since it is impossible to get the 1/32 motor in the market, some users replace their broken motor with 1/64 one but need to reduce the print speed to 6mm/s to get the acceptable quality.<o:p></o:p></div>

<span style="font-family: inherit;"><span style="font-size: 11pt; line-height: 107%;">Luckily,
101hero is using the controller with bipolar stepper motor driver <a href="http://www.allegromicro.com/Products/Motor-Driver-And-Interface-ICs/Bipolar-Stepper-Motor-Drivers/A4988.aspx" rel="nofollow" target="_blank">A2988</a>, </span>We able to replace the 28BYJ-48 with NEMA stepper motor without
changing the electronics. </span><br />
<br />
To replace the 28BYJ-48, you need an adaptor to mount the
NEMA motor to the pylon. There are two type of NEMA motor widely used in 3D
printer. They are <a href="http://reprap.org/wiki/NEMA_14_Stepper_motor" rel="nofollow" target="_blank">NEMA 14</a> and <a href="http://reprap.org/wiki/NEMA_17_Stepper_motor" rel="nofollow" target="_blank">NEMA 17</a>. NEMA 14 is smaller in size and in general NEMA 17 is lower at cost.<br />

I used to use the <a href="http://www.thingiverse.com/thing:2125375" rel="nofollow" target="_blank">adapter design by Dan Delaney</a> to mount the NEMA
17 motor, it is sample and work. The only drawback is printer only stand on the three
motors that is not very stable. I has to add a base to the pylon to stabilized
the printer. <o:p></o:p></div>

Eventually I combined the design from Don Delaney and Matt Dolan into an adapter in one piece.<br />
<br />
To replace the motor, first release T2 belt, then you can easily remove the 28BYJ-48.<br />

You can use the 6 pin to 4 pin cable that came with the motor to connect to the 5 pin connector in 101hero. Please refer to the below picture for wiring method. Follow the pin location not the color as the color arrangement is not always the same. The 1-3-4-6 pin on the motor side is mapped to 4-3-2-1 pin on the controller side.<br />

Remember to insert the M92 command before printing or moving the arm, otherwise, the controller will use the default setting for the 28BYJ-48 that is 5 times faster than the standard NEMA 1.8 degree motor. I am using M92 X101.4 Y101.4 Z101.4 E95.2. You may need to calibrate the setting and I am using the <a href="http://www.thingiverse.com/thing:1278865" rel="nofollow" target="_blank">XYZ 20mm Calibration Cube</a> as the reference.<br />

You need to cut the aluminium brick so that it can sit on the heat isolator without touching the plastic extruder carrier. The thickness of the brick also need reduced to 10mm to enable the perfect contact between the nozzle and the hotend throat even the isolator is inserted between them.<br />

Thanks Matt Dolan (workshoptinkerers) who designed a E3D printhead carrier for 101hero and you can now download the STL file from thingiverse (<a href="http://www.thingiverse.com/thing:2127629" rel="nofollow" target="_blank">http://www.thingiverse.com/thing:2127629</a>), I am also using this carrier. It is well design and perfectly fit to the 101hero.<br />
<br />
I highly recommend to use the above carrier. Just in case you cannot print that carrier, you can consider using hand made carrier that I had built before Mattew Dolan launch his design to thinkiverse<br />

There are two prerequisite condition before upgrade to E3Dv6. One is Bowden extruder and the other is a power supply with at least 5A output. Let's do some simple calculation on the power consumption. E3Dv6 hotend with 30W heater need 2.5A and four 28BYJ-48 motors need 1.6A that already add up to 4.1A. However I recommend 7A one to prepare for the NEMA motors upgrade in the future. </div>

To use the NEMA as the extuder motor, you need to add M92 E95.2 to your G-code file or the 101hero file if you are printing from SD card. Printing with Cura, you need to add this command in the printer start.gcode<br />

Manually feed filament to the hot end through the Bowden tube is
not difficult when the Bowden tube is short. However, I recommend to use some control
program like <a href="https://www.repetier.com/" rel="nofollow" target="_blank">Repetier</a> to control the extruder, it is more convenience especially
when you always need to change the filament.<br />

Filament is tightly hold between the wheel and roller. The wheel is rotated precisely by the stepper motor to pull the filament into the hotend. However this setup increase the weight of the moving parts that limit the printing speed as more momentum need to be solved when changing direction.</span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">With the bowden extruder, we can remove the stepper motor and the filament door from the hotend assembly. The weight of the moving parts can be reduce to 75g from 135g. A the result, we can have a more accurate prints at higher speeds. If we want to upgrade the hotend (like E3D-v6), bowden extruder is nearly a must. Although Nef Lopez have the solution to put the E3D-v6 hotend into the existing direct extruder, it is not an easy task.

you don't have another 3D printer that can print precise parts, you need
to purchase the extruder set.

you more details on the electric and electronic parts using in 101hero.

<span style="font-family: inherit;">The controller is Sanguinololu clone with ATmega1284P and 4 x Pololu

<span style="font-family: inherit;"><br /></span><span style="font-family: inherit;">The 3 stepper motors for movement is a custom made 12V 28BYJ-48 with 1/32
reduction ratio. I believe the supplier does not use the normal 1/64 one is it cannot provide enough torgue even printing at 14mm/s. I will
go deeper on this topic when talking about replacing the extruder stepper motor to NEMA 17.</span><br />

So if you want to go further, you need to upgrade the power supply. 7A is the minimum requirement if you want to be the superhero.</span></span>hargoohttp://www.blogger.com/profile/00319157762065056319noreply@blogger.com1tag:blogger.com,1999:blog-8414585948292724234.post-47192832920583899662017-03-04T22:50:00.000-08:002017-03-12T08:07:12.253-07:00Stage 2 - 101ironmanThe structure of 101hero is built by plastic. It is not a problem,
the structure of the pylon also very solid. The main issue is on the two
triangle plates and the six diagonal push rods (arms). The material of
the triangle plates is too thin and can easily bent. During printing,
the whole printer will shake that make the pylon move and the arms also curved
and loose the contact with the ball joint. The above two movement can
make the nozzle out of its original position by 1-2mm that create wavy
print. Even worse, it create missing step problem to the weak motor and
create shifted layer. No matter you want to further evolve the 101hero, you should fix the structural problem.<br />

<u>Top and Bottom Plate</u><br />

<br />
My solution is insert 6 aluminum bar into the gap of the pylon. You can
use any method you like, just to make sure the distance between the 3
pylon is fixed and will not move during printing. This upgrade cost me
$0 as the aluminum bar is the remaining parts from my old curtain.<br />

I am using the idea from David Leeds who glued a 2mm carbon fiber rod
to the arm and attached weak springs to them. This upgrade cost me $4 for 4 x 1 meter carbon fiber rod and $1 for 8 springs. I just used one rod and still have 3 remain. This solution provide similar improvement as the carbon fiber arm but much less in cost.<br />

For the remaining carbon fiber rod, you can also use them to strengthen
the structure of the triangle plate as what David Leeds did (<a href="https://www.facebook.com/groups/101herounofficial/permalink/1225738600837035/" rel="nofollow" target="_top">https://www.facebook.com/groups/101herounofficial/permalink/1225738600837035/</a>)<br />

Last Christmas, it is printing ok. But the very next day, it gave it away. I believe most of the owner gone through this. I tried everything to improve the print quality and stability. I disassemble the 101hero into pieces. I break the cable of the thermistor and hotend, and reassemble it with 2/3 of the remaining metal plate....... I realize the only way out is force the 101hero to evolve<br />
