Hi Guys, I have built a SCARA 3D printer, it is completed. I have an aluminum frame structure, heatbed raises up and down like the Ultimaker. The arms have there motors fixed on the top mounting plate. I have attached a top view of my printer with the critical dimensions. I have been trying for a long time now on and off to make it functional, have used many firmwares from different usersby ScaraMan - Polar Machines, SCARA, Robot Arms
Hi Guys I would appreciate if anyone can help me, I,ve been working on my scara 3d printer for a while on and off. i have posted before on the site, and members have been helpful. The problem i am having is as follows When i home both arms to the endstops, that seems to be good. I use pronterface for that. Then i send a command G0 X0 Y0 Both arms move , but the point where the nozzle will be doesby ScaraMan - Polar Machines, SCARA, Robot Arms
Hi Guys, It's been a while, was on holidays. Now i am back, and trying endlessly to still set up my printer- at least make sure that the arms Link 1 and Link 2 move correctly to the desired locations i have chosen , it seems every time i change a parameter in the firmware , it just doesn't do what i want. I would really appreciate if anyone could shed some light to my frustration. I am tryinby ScaraMan - Polar Machines, SCARA, Robot Arms
Yes seems like that, any way to resolve that ? i will try tonight to set G0 X247 Y0, and see where is ends up. Would it be better if i just had the endstops located on the other side ?? i dont see why the firmware cant handle the present location i have them now .by ScaraMan - Polar Machines, SCARA, Robot Arms
HI I tried your suggestion, but with no success pronterface is able to send command to home end stops for x and y, but after I send a G0 X0 Y0, it freaks. I have attached a link to video and the firmware, please take a lookby ScaraMan - Polar Machines, SCARA, Robot Arms
Hi Invent2Main So you mentioned in your last reply you were willing to help me, I am using your firmware and entered the parameters according to my setup. When I run pronterface I am able to home the x and y motors to the end stops , then I send an M114 command and this is the reding I get SENDING:M114 X:467.42 Y:-200.75 Z:0.00 E:0.00 Count X: -24.83 Y:11.98 Z:0.00 SCARA Theta:-24.83 Psi+Thetaby ScaraMan - Polar Machines, SCARA, Robot Arms
HI Sure i can use your version, what parameters do i need to change in order to work properly ? Thanksby ScaraMan - Polar Machines, SCARA, Robot Arms
hi currently I am using this one, I have attached the zip file when the end stops are triggered, this is the reading I get from pronterface with M114 command SENDING:M114 X:182.57 Y:-127.29 Z:100.00 E:0.00offX:123.50offY:-107.00offZ:0.00 Count X: 152.93 Y:86.39 Z:100.00 Angle_X:152.94Angle_Y:86.39 also, just want to make sure I have calculated the steps correctly, I have entered 53.33 for x andby ScaraMan - Polar Machines, SCARA, Robot Arms
Hi Everyone, i have been trying for days now, modifying the marlin firmware as attached in my previous post. But i still cannot get the arms to go to 0,0 position after homing on the end stops. It seems it wants to go to another position as per image 0523 in previous post. i am really stuck !!! When i move x or y in pronterface. the arms move by the amount in the proper directions, but theby ScaraMan - Polar Machines, SCARA, Robot Arms
Hi Vitamin Rad Thanks for your help. I inputted the values in Marlin. When I home in Pronterface, it does reach the endstops, although I need to place link2 arm slightly away before homing so that Link 1 touches end stop 1st, before Link 2 hits end stop. M114 command reads this at endstops SENDING:M114 X:182.57 Y:-127.29 Z:0.00 E:0.00offX:123.50offY:-107.00offZ:0.00 Count X: 153.82 Y:84.77 Z:0.00by ScaraMan - Polar Machines, SCARA, Robot Arms

I am looking also at wangamas, but it seems that there are noby ScaraMan - Polar Machines, SCARA, Robot Arms
