Hi, good job bro, i´m doing the same project but i have some problems with the marlin´s configuration , (I´m using the marlin from ttsalo) when i start to print using proterface, it says that the printer stopped due to errors of temperature, how did you delete that part of the heatbed and all that things? just for use a marker or pen like you. Thanks for answer me.
What did you use to get it to plot? I have gotten it to move using Pronterface but I dont know how to make it draw something. Any help would be great!!
Thank you. The plans are from here: www.thingiverse.com/thing:1241491 The arms are driven through belts but there is a mistake in a design. Standard 160 and 320 teeth belts are sightly too small so I had to make my own belts with 162 and 324 teeth. Now I am working on adding positional sensors to the arms.
I’d like to build such arm, how have you made it so accurate? Could you open source the project software? How to generate GCode for it? Does it have some grbl software equivalent?
Hello from Spain. I'm become crazy with the configuration of this arm. I'm try with marlin of vitaminrad. Which firmware are you used? And where are you install the endstops? and the last question which is the step per mm that you are calculate in my case is 200 x 16 / 360 x 3 = 26,66. 3 is gear reducction . Please I 'm glad to find somebody that work in the same project that me.
Hello. I also had a lot of problems with the software for that arm. I also tried marlin from vitaminrad but I had a lot of issues with homing procedures. I tried a lot of different positions of home switches but I have problems with trajectory of arms during homing. The arm just collides with itself before reaching home or goes over the max reach. Now I am using marlin from ttsalo. The homing there is not implemented ( it's manual) but it's not a big problem for me. Anyhow I am working on adding some positional sensors to the arm and writing my own software for it ( I don't intend to use it for 3D printer). I guess the software from vitaminard should also work but I could not configure it properly. Gear radio is 3.1 therefore steps per mm are 27.55555.
Thank you very much for you replay, I will try the ttsalo marlin version in my scara arm, but I don't understand some data of the configuration because I thought that this arm is a single arm no a parallel as the version of marlin ttsalo. +//// SCARA settings++// Arm segment lengths+ #define SCARA_SEG1_LEN 100.0+ #define SCARA_SEG2_LEN 150.0++ // Rotation axis Y position+ #define SCARA_AXIS_Y -82.0++ // Arm base axis separation+ #define SCARA_AXIS_SPACING 75.0++ #define SCARA_MOVE_APPROX_LEN 1.0 For instance scara_axis_y is the offset ? The spacing how calculate this and the last scara_move_approx_len? I'm sorry but I don't understand. Thank again for you replay and need make run this arm because now is my personal target.
This is a parallel scara arm. The angle of second linkage is not determined by both motors (like in serial scara). If you turn only first linkage (closest to the base) the second linkage will just translate and remain parallel to it's initial position.
Thank for you explanation about the theory of this arms but I only work with cartesians printer, maybe the problems that I have had during this time it has been this. I 'm going look for information about the parallel scara and I try to learn for myself a little bit more about this robots. Thank you and let me ask you if I will have problems, ok.
I already test the ttsalo firmware and I use your marlin configuration but when try to test for instance cube square of 20x20mm the arm draw a square but oblique it seem that somthing is wrong. I can't understand this line of marlin define SCARA_MOVE_APPROX_LEN 1.0 Maybe is this make the configuration wrong because the step per mm is ok. Other thing is which is for you the motor that move x axis and y axis

very good
Other thing that I must to do is to connect a thermistor in the ramps boad, because if I didn't connect it the marlin show a error.

como configurar esta impressora?
Which microcontroller have you used for this robotic arm?
Very Nice project, it's very precise? I think it require more reduction
hi, nice work. I am currently doing the same project. May i know where did you place your endstop? thank you
I don't have any endstops right now.
What did you use to get it to plot? I have gotten it to move using Pronterface but I dont know how to make it draw something. Any help would be great!!
Looks like it is just running 3D printer gcode tbh.
Very nice project sir, smooth moving..What firmware do you use?
looks like 3d printing firmware , due to the nature of the drawing looks like its drawing infill layers
Ola! teria com me enviar este código?
Very nice! Where did you get plans? Is it using belts?
Thank you.

Hello can u send me your email pls

Can you use an Extruder on this one? I just 3d printed one out. Thank you
I guess yes but I haven't try that.

Please read the other comments before.
I described it there. It is running marlin software with configuration described in the comments

Today I try the firmware in my robot arm and I have one doubt, the distance between axis in this scara rm is 0 isn'it?
I already test the ttsalo firmware and I use your marlin configuration but when try to test for instance cube square of 20x20mm the arm draw a square but oblique it seem that somthing is wrong. I can't understand this line of marlin define SCARA_MOVE_APPROX_LEN 1.0
Maybe is this make the configuration wrong because the step per mm is ok.

Check the deffinition of manual home position and the actual position of the arms when you apply power to the board.
puedes ponerte en contacto conmigo para ayudarme con mi scara?
hi make but it dosent work can u help me?
it will write but have some mistake with writing
Hi. Source code pls.
Have you try the wangsama firmware ?
no
bruh its 3d printer working in 2d
