2x "Z-Motor"

2x "Y-End"

2x "X-End"

1x "X-Carriage"

1x "Motor"

1x "Hotend"

1x "Hotend Clamp"

1x Bowden Extruder by benni (You can download the Files at the bottom of this step)

###If you have problems with getting the printed parts, feel free to contact me :-). I can print them out for you.###

Step 4: Modify the 28BYJ-48 Steppermotor

Picture of Modify the 28BYJ-48 Steppermotor

To change the 28BYJ-48 from unipolar to bipolar, you need to open the blue plastic case.

After that cut the the connection and desolder the red wire (see pictures).

Then solder the wires in this order:

blue--yellow--orange--pink

After this hack, you can connect these motors directly to Ramps 1.4.

Step 5: Y-Axis

Picture of Y-Axis

At first, you need to glue the wood plates together.

After that, place the printed parts " Motor ", "Z-Motor" on the wood plates.

Then you screw the printed parts down.

After that you put the motor in it, then the LM8UU.

For the motor, you put the pulley on it and connect the 624zz bearings.

For the LM8UU, you use some zip ties.

Then you put the two 17,5cm 8mm smooth rods in it.

At last you assemble the belt to the "Y-ends" and mount the endstop.

Step 6: X-Axis

Picture of X-Axis

For the X-Axis, you need to :

- put two M4x45mm into the "X-End"

- connect the motor, like you see on the pictures

- thighten the belt and mount the endstop.

- connect the hotend with two M3x25 Screws + Nuts

Step 7: Z-Axis

Picture of Z-Axis

To assemble the Z-Axis, you need to:

Put the LM8UU into the "X-Carriage" + " X-Ends"

Then put the "X-Ends" + "X-carriage" with the 17.5cm smooth rods (X-Axis) and 21cm smooth rods (Z-Axis) together

After that you screw the threaded rod with the motor together.

Step 8: Make the Printbed

Picture of Make the Printbed

You drill four 3mm holes in to the 20x13cm wood plate.

After that you screw four M3x25 screws in it.

Step 9: Put Everything Together

Picture of Put Everything Together

Step 10: Connect the Electronic

Picture of Connect the Electronic

Connect the electronic, like you see on the picture.

Step 11: Firmware

Picture of Firmware

Update 29.02.2016:
Here is the latest Firmware for the Cherry 3D-Printer.

  • This time I'am using the latest Repetier Firmware 0.92.8.
  • I enabled Eeprom so you can easily change basic parameters

What you need to do:

  • Upload the pre-configurated firmware to your arduino mega 2560
  • Then open Repetier Host, go to the top left corner, open configurations and then you can load the Eeprom file with all the important parameters

Where can I adjust the parameters?

  • If you have some basic parameters to change (steps per mm, feedrate, acceleration...), open your Repetierhost, and go to Configuration --> Eeprom

Step 12: Photos From Print

Picture of Photos From Print

After some calibration, I have printed a good 1x1x1cm calibration cube.

Resolution: 0.2mm

Speed: 10mm/s

During the calibration, I found out, that when the motors get too hot, I have extremly layershifting.

So you need to set the A4988 to 1/16 microstepping and adjust the current, to a minimum.

Also play a little bit with the backlash in the repetier-firmware.

More pictures from print coming soon :-)

Step 13: Nema 17 for X,Y and Z Axis

I made some new parts for the X and Y Axis, that you can easily attach Nema 17 Motors to your Cherry-Printer

For the Z-Axis, please use the files from CrimsoRo who made a great job :-)

You can download the files for X and Y below.

TECTEC3S (author)2017-10-15

I have found one massive issue with your pieces on Thingiverse. Have you ever heard of TOLERANCE? The pieces you have designed for this project have almost zero tolerance. This is a huge flaw since the majority of people who would want to make this design don't have great printers. Even on a good printer, doing 0.2 mm layer height is not feasible since the tolerance level is so perfectly fitted to the pieces that have to go inside of it that the tolerance at 0.2 is not good enough. If you were to take the existing pieces, and make the tolerance just a bit better, i'm sure it would make it much easier for all of the people who want to make this prionter to actually make it.

About to start the printing process, have to wait 13-40 Days for all the parts to arrive from China, Sending my thanks all the way from Australia for sharing this with the world!

kieranrand (author)KieranR172017-10-05

Majority of parts printed, Some curling quite a bit however not affecting how the printer is assembled. Will post photos in the coming days. Also ordered some longer linear rails that have given me some extra length for all three axis.

Hi ,I would like to know if this model can be applied on scale of 15x15x15, thanks in advance.

sagiro (author)2017-08-20

How tense the belts have to be?
I tried putting them on the y axis and they seem to shift out of the 624 bearings...
I tried tensing it a bit and it seems to help but now the motor shaft is a bit bent... if I release the tension it goes back to the original position.... can anyone help me with this?
thanks in advance.

on-animation (author)2017-07-29

Hello!

Perhaps anybody can help me...

I have communication problems only when the extruder is heating. It makes that the printing stops and the printer remains frozen. I need turn off, unplug the USB cable and restart the Repetier Host software...

When I tick the Dry Run option in Repetier Host and the printer works fine for hours. But when I print normally with the extruder heater I have communication problems and the printer finally stops.

Any idea about what can be the problem?

Thanks in advance!

Faman (author)2016-10-27

Hi Vulcaman and many rhanks for this instructable

I'm actually building my own cherry printer and have a question about the endstops. Do i have to set them NC or NO ?

Also, about the unipolar to bipolar trick, for the 28BYJ-48

So i desoldered the red wire; but the other cable seems to be in a different order from the pictures here

the order in your picture is : blue.pink.orange.yellow directly at the exit of the blue casing

the order in my motors is : pink blue yellow orange

So i assume that your blue is my pink, your pink is my blue and so on...

then if i want to connect the ramp board such as your blue--yellow--orange--pink code; then i have to set mine as pink-orange-yellow-blue

do you think it's correct ?

before doing stuff with it i would like to try them out, is there an easy way using the ramp and arduino to test the motors to see if they are well set ,

many thanks for the answer

sagiro (author)Faman2017-07-10

I hope you figured it out by now.... and since no one answered.... I'm facing the same problem.... I'd like to know what you found out about the colors on the motor.
I'd appriciate the help.

saw90 (author)2017-04-22

Hi all. First of all; great project. I am very new to this and had some quetions. Mainly what is the purpose of the nema 17 stepper? Does it feed the print medium? my second query is about the stepper motor hack, is this a necessary step as I may wish to reuse them in another project. Thirdly, for the PSU any recommendations?

JimBOB321 (author)2017-04-09

Hi everybody ! That's me again ^^'

Thanks to etetan's answer, I could make some progress but there is still a little step to do in order to print correctly my first piece.

When I start printing a piece, no problem ! Everything seems working well... but after few minutes, the extrudder motor skids on the filament. Nothing else goes out from the extruder. The extruder nozzle is blocked.

So, I bought new extruder nozzles (0.6mm instead of 0.3mm). But same results after a little more time.

I use 1.75mm PLA filament heated up to 210°C. (enclosed you can find temperature curves and extruder EEPROM parameters, problem came at 52minutes).

Does anybody have the same issue ? Any solutions to fix it ?

Thanks in advance

etetan (author)2017-03-25

Would anybody be interesting in purchasing the 3d printed parts if I were to print them out? I am willing to but only if there is some demand to do so. I would sell all the parts for about $20-$25 CAD and sell them on ebay. Reply to this comment if you are interested

The EV (author)etetan2017-04-09

Please do, I don't have a 3D printer and really want to build this project.

Could you post the link if you are going to sell the parts

gdmakerspace (author)etetan2017-03-26

I'd buy it for $20 CAD

What printer would you print it on, what filament would you use?

etetan (author)gdmakerspace2017-03-26

Its one i built out of aluminum. Honestly great quality. Id print it using 3DSolutech PLA (in my opinion it is way better than hatchbox) at 0.2 mm layer height. I have purple, cyan and black filament right now

etetan (author)etetan2017-03-28

I could even do it in PETG

guys347 (author)2017-04-08

which power supply do you recomend, and it will help if you post a link to order the itam, thanks alot

Hi I am collecting money to buy all parts requiered to build Cherry 3D Printer but i dont have 3D Printer myself. Can i use wood pieces as replacement of plastic parts?

etetan (author)Karl JakopP2017-03-09

You make them out of wood and then if you want, print them with the printer you just made

Arhaxor (author)etetan2017-04-02

Hi etetan I have the same problem as you had could you tell me how u solved it ? the motors are not moving in any axis I checked the connection thermistors baud rate 115200 decreased the steps per mm but the motor is not moving

Faman (author)Karl JakopP2016-11-01

Look at the comments above. Several people here made the genuine plastic parts entirely from wood. It's seems to be efficient.

JimBOB321 (author)2017-03-03

Hi folks !

Firstly, thank you Vulcaman for this tuto, you rules !

Secondly, I am making my own one following your instructions. Everything is connected and I could test every component individually (motors X/Y/Zs/extruder, Endstops, extruder, temperature probe, ...). But now, when I test all the components connected at their right place (with the test commands in the repeiter sw), the extruder motor doesn't work : no move, no vibration, no noise, nothing...
I use the EEPROM config given in the tuto without major modification, I tested the A4988 (OK) and the motor (OK). I also tried to adjust the current of the A4988 and to modify the micro-stepping : Still not working (no move, no vib, nothing...)

By the way, when I try to turn the rotor of this motor, it is a bit harder than when the motor is not powered, so I don't think that is a power supply issue.

Does anybody have the same issue ? Any solutions ?

Thanks in advance

etetan (author)JimBOB3212017-03-09

Hey, so the problem is most likely the fact that the extruder stepper will not move unless the hot end is heated. If you want to make sure the extruder works, heat the hot end to the temperature you intend to print on (for PLA aprox. 210 degrees Celsius) and then you can test it. This is just a safety feature built into most 3d printer firmwares so that the extruder is not trying to feed filament when it cant actually extrude it.

Arhaxor (author)etetan2017-03-30

I have the same problem Ethan I uploaded the firmware but eprom is grayed in repetier the motors are not moving the extruder is connected as well as the thermistor

JimBOB321 (author)etetan2017-03-11

Thank you etetan for your reply. ;)

I will test it and maybe print my first piece soon !

richardyan0309 (author)2017-03-17

Hi, can you send me the size of your wood board that you are using? like where to cut it.

jammoyano (author)2017-03-30

Hi all,

First, Thanks Vulcaman for this project ..... I'm buildim my very first 3D printer ...

Second, I've some questions, please be patience ... ;-)

Y-Axis:
What is the distance between the edge and the supports of the motors X? (blue)
What is the distance between the supports of the X motors and the central support? (Red)
The nuts holding the motors should screw on the underside, right?
The rotor should I be at the absolute center, I guess (green)

Ramps:
1.- Under the pololus there are 3 pins, what is the exact order in which they need to be connected? (0, 1, 2, 3, ...)
2.- What is the order in which you connected your engines? Blue cable the first by the right or left? My engines have a different order (except red in the center ...)

MatyášK2 (author)2017-03-28

You do not know what a 28 byj 48 after hack angle step or steps per revolution thank you.

samuelb1002 (author)2017-01-14

Hallo

Still can't het the printer to work.

The X and Y are working, only for the Y I have an issue with the endstop I it keept on moving even if the endstop led illuminaties to indicatie that the carrage has reached the end.

The major problem is however with the z and the extruder stepper motors.

The z-axis I could get moving for a while when using the 3 jumper to have it run in 1/16 mode. However after a while no movement anymore ????

The Extruder stepper is true drama it vibrates (gets worse when increasing the voltage on the stepper driver pot's) or I get it moving but then it jumps steps all the time. I wired stepper and stepper drivers on other positions (X and Y) to verify if the stepper or the driver are fine and they are. When pluggen in on X or Y all is fine.

I tried adjusting the voltage on the stepper divers setting it to 0,5-0,6 volt but this is not improving, on low voltage no movement the high voltage results in skipping of steps and overheating.

Started fiddeling with some of the EEPROM settings but honestly I have no clue what I need to do.

Can you help me with my issue's?

Thanks,

Samuel

Vulcaman (author)samuelb10022017-01-19

Hi,

You have to set the A4988 in full step mode for the Z-Axis. Then try to adjust the current of the motors and steps per mm. You need to find the perfect match between current and torge. The Eeprom can be adjusted in Repetier-Host. Here you can set the steps per mm for all the axis.

For example if your motors doesn't drive as long as you set, you have to increase the steps per mm for the specific axis.

Tarps87 (author)Vulcaman2017-03-21

Hi

After setting the Z jumpers for full step my motors only move a fraction then stop. What are the likely causes?

Thanks

samuelb1002 (author)Vulcaman2017-02-02

Hallo

I needed to modify the steps/mm setting of my Z to make it move but will my dimensions now still work?

I mean the EEPROM says 2500 steps/mm and I needed to set it at 400 steps mm. What will be the effect of this if I try to print a 10x10x10 cube.

Extruder is still a problem no movement only vibration.

Samuel

samuelb1002 (author)Vulcaman2017-01-22

Hallo


An update again, X and Y are OK, endstops are also OK. The Z I can move but very slow at first and at 400 steps per mm while the documentation of the printer indicaties 2500.

I can make it move faster if I increase the feedrate however then I have another strange effect, the stepper motor changes direction at random ???? however both stepper motors Z1 and Z2 are in sync.

The extruder is again a problem I exchanges its stepper driver (to check A4988 vs DRV8825 performance) switched it back and the vibration is there again no way to find a good setting of the steps/mm. documentatie indicates 145.5 my previous setting of 80 no longer works.

This thing is driving me crazy working on it for a few months now and still haven't printer anything.

Samuel

FireCrier (author)samuelb10022017-01-23

Hi,

if your motor changes direction randomly (in case we are talking about 28BYJ48 and not a NEMA17 type) the most possible issue is wrong connection. Don't rely on the wire colour. Different manufacturers - different wire color order. For me this issue was a little hell as well :) Double check this even on the motor's PCB. Vibration of extruder motor is of course much bigger than other small motors. Setting around 145 steps/mm should be OK. Driver trimmer pot has to be set at higher level than other motors (based on the fact that NEMA17 literally 'consumes more' than 28BYJ48 :) ) How much torque does your extruder motor have anyway? Send us a data about manufacturer and model of your motor if you don't know...

FireCrier out.
