    Can i run makelangelo without led display… If yes how will i change the source code to run the program and draw.??

    When i tried to draw an image an error message came

    N5 m117 change to black click to continue*47
    N6 m300 s60 p250*20
    N7 m226*34..

    And nothing happens… And i can draw vectors only… When i try to draw jpeg this error message comes.. And also the machine cant find home position… My machine size is 930 mm width and 563 mm height… … When i try to draw on a4 paper the image exceeds the paper.. Hope someone will help soon..

    Those three commands say

    – display message “change to black click to continue”
    – make beep sound
    – wait for user to click button

    If you have no LCD screen then you will not be able to proceed unless you upload firmware with HAS_LCD disabled.

    > When i try to draw jpeg this error message comes..

    What error message, specifically? Ugh.

    > And also the machine cant find home position…

    Why not? What happens? It sounds like you’re running a DIY Makelangelo 3 which cannot find home position automatically.

    > When i try to draw on a4 paper the image exceeds the paper..

    Did you go to settings > paper and choose A4?

    Hey.. Dan i figured out solutions for some of the problems my self bt….. I have some problems regarding the size… The image printed on the paper seemed to be squeezed from the top…… I couldnt correct this mistake..

    And also the size of the print is larger than that of the paper….
    How can i correct these dan?,

    Please post a screenshot of your app and a photo of your machine and the results drawn. Position the pen holder at the home position in the photo.

    Ok dan…
    Here are the links to my google drive

    https://drive.google.com/file/d/1-To6slQYx_d-BoePfyn8A78oHCzsmrrZ/view?usp=drivesdk

    https://drive.google.com/file/d/18dYk53xh_gEZogR5U211tLXeJp5GUKuG/view?usp=drivesdk

    The width of the drawing is ok… But the height seems reduced.
    I dont know how to fix it
    .. Machine size is… Height = 569mm

    Width = 930 mm

    I selected A4 size… But when i drew first it drew outside the paper so I inserted a paper of bigger size so that i would get the complete image.. And after drawing i could tell from the image that it looked like it was squeezed….

    Is it because i measured the height of the machine wrong??

    Check your microstepping (should be 1/16th) and check your pulleys (20 teeth each).

    Yeaa i did that… And when i tried to draw a 10 mm square the dimensions were 15 mm in vertical side and 20 mm in horizontal side… So i figured that the machine draws a 5 mm excess on vertical side and 10 mm extra in horizontal moment… And what i am going to do is…. Ill try adjusting the size of the board… Ie incriment and decrement these values from size of the board 😂😂.. I hope it works… And if there is any other soluthon please tell me and ill notify you if it works

    I suspect your pen holder design is a problem. measure the width from the center of each motor shaft and subtract the distance between the pins on the pen holder that attach to the belts. In my design the arms swivel around the pen tip. In your design they swivel around two different points and that has to be compensated.

    Dan for drawing 10 mm vertically the machine draws 15mm

    And for drawing 10 mm horizontal the machine draws 20 mm…..

    Have you heard abt this type of error… I cant fix it by changing the mavhine size.

    Is there any other way to fix this??

    Considering the source codes side…
    Anything i can do to make macjine draw a 5mm less on the vertical side and 10mm less on the horizontal side

    I didn’t say belt size. the belts attach to your DIY pen holder about 8cm apart, on the brass colored pins. subtract the distance between the pins and you might get a more accurate picture.

    Also that distance between the pins will cause the pen holder to tilt sideways sometimes, which will also affect the quality of your drawing.

    I need a more thorough description of your system because I don’t see what is going wrong.

    I’ve tried to help you out. I didn’t build your machine so it could be a great many things.
    Try a video that shows the entire machine and then shows the system while it is making the problem.
