Goodday Kushal, Nice job there u working on. I'm just wondering which firmware you uploaded to your RAMPS 1.4 board? The reason I asked because I too have RAMPS 1.4 board to make a 3D printer based on Ultimaker. Unfortunately due to my lack of knowledge in electronics stuff results the 3D printer making to nowhere :-| . I also would like to know more on your electronics connection for this project. Many thanks. -Sam

Oh ya, is it possible to change the orientation of the object in pronterface? I tried looking for the button to change the orientation, but I just couldn't find it :shock:

Ok, I did uploaded the new Marlin firmware into my UM, the thickness is still the same. Then now I try using pronterface. But tbh I really don't know how do I check the current setting for my z-axis or thickness for my object.. I send command M503 but it seems nothing happen, not show anything about my current setting.. :oops:

Yeah I did got a new RAMPS board, but that board is for my not-yet-finish-build 3D printer. The printer that I hv this problem right now is my UM printer. Probably the problem is with the codes. The problem is that I hv the firmware uploaded into my UM long long ago, and I'm not change it since then. This is because I dunno where did I saved the firmware program :mrgreen:. I was thinking of uploaded the new Marlin firmware into my UM but I'm really afraid if something I don't like will be happening. :shock:

@gr5 So, after I downloaded the Marlin firmware, I should upload it into my UM?

Only *after* print. In Cura it shows full length. Then I printed the part, the height only half from the Cura. Okay I will try to download it. Thank you for the link.

1) Which part should I look for steps-per-mm for z axis? 2) Also where should I look for the stepper-drivers micro step setting? No i don't have ulticontroller, all the setting I set all from Cura. It's the same result when I used Cura 12.08 and Cura 13.06..

Hi beautiful/gorgeous people, I'm facing a new problem recently. My prints for X and Y axis are good, just a slight problem I can solve. However, for the height (Z-axis), all the thickness of my prints reduced by half, either the STL files I downloaded or the files I created using CATIA. As far as I concern, I didn't change any setting for the thickness, in fact I didn't found any setting for the thickness as well. Any idea? Many thanks.. :???:

Hi community, It's been a long time since my last post. So recently I bought a new set of 3D printer kit from amazon: http://www.amazon.com/RAMPS-Iduino-Endstop-Cooler-printing/dp/B00CXMVQLK. The idea is I am trying to make a new 3D printer of my own.

Next step I open PronterFace software, connected the board and it goes well. In the same time I assembled the Pololu stepper driver, the motors, and limit switches to check the electronics. When I clicked on the circle near the axes X- and Y-, my motors not moving, and an error stated in the red box in the figure (I dont understand what it is but something to do with temperature? And yes I'm not yet connect any temperature device, I just want to see the motors moving). Same goes to the Z-axis motor. Then I clicked on the homing position button, however, all the motors rotates well. Limit switches also works. #1 question: why I cannot jog the motor but homing position motor works well? http://umforum.ultimaker.com/index.php?/gallery/image/1497-error1/ Then I disconnected the electronics from PronterFace, and tried connected to Cura 12.08 and it was connected successfully. I tried connect it to the latest Cura but it cannot connect. And then I simply clicked "Print Gcode" as my intention to see the motor moving. The motors moving at first, seems like they moved to home position. Then they not moving but the print indicator stated it is printing as seen in the figure link below: http://umforum.ultimaker.com/index.php?/gallery/image/1498-error2/ The "Line" section is increasing even the motor not moving. #2 question. Is it any error in the compiled firmware? Well, tbh I'm really not that good with the coding in the firmware. Any helps, tips, and guidances are really appreciated. -Sam

Hi MSURunner, Yeh u right. 1 of my pulley attached to the motor was loose, so even the motor moves, but the nozzle head didn't move. I already tighten it and lubricated all the rods, and now it works good again. Thanks :mrgreen:

Hi Daid, I did like u said, at first it works. But now it happened again, even worst. I'm suspected that maybe my belt misaligned, that makes the nozzle head hard to move, and stuck a bit on its journey, that lead to that situation. I will check my belt alignment. Other than that, do u hv any idea? I already tighten all the axes pulleys. Many thanks in advance

Thank you Daid, I'll check into that. It's tinkercad from http://www.tinkercad.com , I used it because I just want to draw a simple shape.

Hi all, Refer to the picture, its not suppose to be like that, is suppose to be a rectangular part. But any idea why the left and right sides happened to be like that? I check all motors are tight in their place. Is it because of belt slipping? Thank you in advance.

Hi all, After successfully print using Cura, I decided to change back to RepG for some features available in there. But for some reason I cannot connect to RepG. So I decided to try NetFabb, and I'm using Demo version since I'm not purchase it at the time I purchase my UM. I read some of the threads in Netfabb topic, and followed as suggested, and things didn't go as I expected. I got error as attached. Any idea? Many thanks.

Well, I did tried. I want to have a circular pattern infill for my solid cylinder object, but the 1 available in the expert setting is only for non-solid object. In fact, all the settings for infill pattern in the expert setting are all for non-solid object. Maybe Cura still don't have the options yet.
