<p>Hey</p><p>I am somewhere half of the build trying to connect a LCD Full Graphic smart controller but I can't make it work. Backlight is OK but that it.</p><p>Can anyone help me.</p><p>Thanks</p>
<p>take a look at this: <iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/H3wj9l1hvVw" width="500"></iframe></p><p>it's the tutorial i used when setting up an LCD for my main printer.</p>
<p>Hey</p><p>Hooking up worked but it seems to be an issue in the firmware. So you did not need to make any modifications in the firmware you just hooked it up?</p><p>Samuel</p>
<p>yeah, i had to enable the LCD in firmware. it's all in the video.</p>
If you Make everything twice as Big (for bigger build space) wil it still work?
<p>you'd probably only need to make the steel rods longer, and the build plate bigger.</p>
<p>Hi people.</p><p>i just finish yesterday to wire everything on my cherry printer. I then install repetier host and try to test each motor. </p><p>first, they are all very hot, i figure out that i have to set the voltage for each, i don't know how to do this, if someone could help me on this point ?</p><p>second, i actually succed only to move the Z motors. But they are very slow. i tried to set them to the home position, the whole axe only move for 10 mm down and stop. When i command an other movement down, it goes up ! :-/ I'm actually trying to understand the logic of this...</p><p>third, the X and Y motors absolutely don't move at all. Maybe i'm wrong in the wiring, i heard some whistle noise inside when i command them. The only thing they manage to do is getting really hot both but they don't move.</p><p>The firmware is the one linked here by vulcaman so i assume the settings are good.<br></p><p>last : aboslutely no move on the nema 17 extruder motor, no sound, and he remains cold, so i don't know if it's working or not...i saw that it's not supposed to move unless the hotend temperature is idle, i will try to otherpass this in order to test.</p><p>As i stated on another post, the wires color of the 28byj-48 motors are in a different order from the picture i can see here, i don't know in wich order i have to plug them on the ramp board. It appears i set them right for the z-axis, as they turn (but slowly), done the same wiring for X and Y but they are still stuck.</p><p>Any help would be really appreciate =)</p>
Hi, is who of Minsk (Belarus)? left only print themselves details printer :) everything else is already!
Is who of Minsk (Belarus)? left only print themselves details printer :) everything else is already!<br><br>Есть кто из Минска (Беларусь)? осталось только распечатать сами детали принтера :) все остальное уже есть!
<p>Im considering to build this for a school project. However i cant figure out how ou would print from the finished product? Am i supposed to buy a smart controller? And how would i attach everything?</p>
<p>What kind of wood was used for the print bed? It wasn't listed in the parts list, and definitely was MDF</p>
<p>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?</p>
<p>Look at the comments above. Several people here made the genuine plastic parts entirely from wood. It's seems to be efficient.</p>
<p>Hi Vulcaman and many rhanks for this instructable</p><p>I'm actually building my own cherry printer and have a question about the endstops. Do i have to set them NC or NO ?</p><p>Also, about the unipolar to bipolar trick, for the 28BYJ-48 </p><p>So i desoldered the red wire; but the other cable seems to be in a different order from the pictures here</p><p>the order in your picture is : blue.pink.orange.yellow directly at the exit of the blue casing</p><p>the order in my motors is : pink blue yellow orange</p><p>So i assume that your blue is my pink, your pink is my blue and so on...</p><p>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</p><p>do you think it's correct ?</p><p>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 ,</p><p>many thanks for the answer</p>
<p>Hi, i built your printer entirely out of wood because i had neither a 3D printer on hand nor do I know anyone who has one.</p><p>Now i faced the following problem:</p><p>The Z-axis moves about 10 steps without problems, but as soon as it should move more than this, it doesn't anymore. However, I can move the axis in multiple &quot;step-groups&quot; all the way up/down, wedging isn't the problem. So I increased the driver current to the max. The motors just get hotter, but it doesn't work any better.</p><p>Do you have any tips or have you even faced the same problem and solved it?</p><p>Thank you</p>
<p>Hola por favor que alguien me ayude, esta impresora no necesita cama caliente???</p>
<p>Hola que tal imprimi mi primer pieza en mi version de cherry pero sale chueca imprimi un cubo pero cuando se termina de imprimir el cubo sale de lado como la puedo calibrar alguien sabe</p>
Hi what is your email? I have a private concern . Nothing bad. Just want to share in private.<br>Kind regards. You are as old as me and you do well???
<p>You have a private message. Check your inbox here on instructables.</p>
<p>Hi,</p><p>thanks to Vulcaman for this Instructable! Some important informations are missing, which increased the build time for me, but i also learned a lot, while searching for this informations.</p><p>It found 3D printers very interesting, but would never have spent 300&euro; or more. The prices was the only reason i build one!</p><p>While the build process i learned how disgusting slow these steppers are and decided to use NEMA 17 for X and Y.</p><p>I reworked the Y-carriage and construced a X-Motor-carriage.<br>I also constructed a Z-endstop-holder to get rid of the cable ties, shortened the hotend-clamp and did some other slight modifications.</p><p>Now i am able to print up to 150mm/s, but used only 60/80mm/s (perimeter/infill) until now.</p><p>The printer actually has 2 problems:<br>-The PLA is not cooled and is not hardening fast enough<br>-I used 3mm filament, but the extruder cant handle it and is slipping. (Too much force is needed) I will change it and use 1,75mm in near future.</p><p>At the end i think, i spent around 80&euro; and a lot of time for printing the parts with a leaned printer and building everything as accurate as possible.</p>
<p>Espa&ntilde;ol: como se llama el papel azul que tienes en la cama de tu impresora?</p><p>English: What's the blue paper do you have in the bed of your printer?</p>
It's TESA outdoor masking tape 4439
<p>Hey Bender could I get your EEPROM data, every time I set my x and y speed to 500 m/s it tries to print somewhere off the print bed. . .</p>
<p>500m/s is way to much. If you mean 500mm/s, it is still too much!</p><p>Try to start with 20mm/s and reduce the acceleration.</p>
<p>Update:</p><p>I printed a new fanduct, added LEDs and a selfmade heatbed for printing ABS. (I am still below 100&euro;)<br>The heating is made of some high power resistors (118W in sum), glued to the bottom of the plate, who reach 100 degrees in 8 minutes.</p><p>I also have a video (PLA) avaliable:</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/oVHkzdN7KEw" width="500"></iframe></p>
<p>Can you send arduino files?</p>
<p>Love your printer. Is it possible that you can upload your modifications to Thingiverse? Thanks </p>
<p>Your printer is awesome for that budget. The results are very accurate. Respect !</p>
Thank you very much, i never would have build one without this instructable. I tried to improve the accuracy and reducing the tolerances of assembling very long time.
<p>So i am also using nema 17 stepper motors for controlling the x y and z axis instead of the </p><p>28byj-48 Steppermotors could you tell me what modifications you did to the code, or settings you changed to allow for a faster speed?</p><p>Thanx </p>
<p>Nothing special! You just have to calibrate the steps per mm and then u can set the maximum speed for X and Y in repetier firmware or eeprom. try also some different acceleration values. (500mm/s&sup2; works fine for me)</p><p>I reach 300mm/s travel speed. (Havent tried more)</p>
<p>oh i get it, thanx for the reply amazing work by the way</p>
<p>Hello! Nice work. One question. Do you want to send a 3D model for nema holder on X axis...</p>
<p>Great idea with the Nema 17 Motors for the X/Y Axis . Nice work and a good testprint !</p>
<p>Great idea with the Nema 17 Motors for the X/Y Axis . Nice work and a good testprint !</p>
<p>Build size: 155x100x120 (X,Y,Z)</p>
<p>Kann das sein das es bei mir ein fehler gibt? Wenn ich einen Druckauftrag starte setzt er dem Homepunkt auf null und bewegt alle motoren zum NULL Punkt Problem ist Z der kommt an den END Stop und der Cherry geht aus danach geht nach neu Starten des Auftrages alles wieder von vorne los.</p>
<p>3D Printer- Cherry XL 200x200x150 with heated bed. We are in the middle of calibration. This is some test print. Thanks to Vulcaman</p>
good job can you send arduino files please I need this
<p>Can you post more photos and maybe a video, would really love to see more</p>
<p>Hey. The XL Version looks great. Did you just change the size of the MDF Plates and the rods? Would you mind posting the dimensions for your 200x200 version?</p>
<p>Dimensions are there</p>
<p>Thanks!</p>
<p>Hi mate, very good and cheap design, I have already built it :) having only one problem, can you please help me?</p><p>I manually put Z into 100 in repetier, but in real it will go up only by 1cm. So it looks like it is moving it only by 1/10th of possible area. I have imported your eeprom, havent changed anything, but was trying to adjust Zax steps per mm, but with no luck... (I havent used any different material, everything same as yours. Thank you</p>
<p>Solved: edited Z axis steps per mm to 80000, so 10 times more than normal (because I put DRV8825)</p>
<p>just to mention, X and Y are ok. They move 10cm both</p>
<p>Friends I have a big problem, the cherry 3d ago microscopic prints, manually moving the motors move, but launched the press me from this problem ask for help</p>
<p>If the prints are smaller than expected, check to make sure the units in your CAD program are exporting correctly. Another problem could be your micro-stepping settings. Make sure when you are calculating your axis resolution, you are taking your micro-stepping into consideration, otherwise the scale of the parts will be off by a multiple of 2. </p>
Anybody have problems with comunication port?<br>&quot;Warning missed lines...&quot;?
