3d print from start to finish om my X-SCARA 3d printer. I found this design om github. Check it out! github.com/madl3x/x-scara I created a discord server if you want to contact me: / discord
Cool idea but eventually those arms are going to start sagging. That's why you see cranes or bridges with another support to offset the load in a triangle format.
I don’t think that will be much of an issue, especially if the arms are rigid enough and the correct types of bearings are used. Scara robots are designed that way so that the motors on the arms don’t have to lift the weight of the arm, it is all supported by the Z axis. They are a pretty common way to make a robot arm, if they had any significant drawbacks then they wouldn’t be used. Any deflection or sag can be compensated for anyway, especially since they have a bed levelling probe next to the nozzle.
@@conorstewart2214 Thank you for the comments. If you want to exchange more ideas, come find me on the Discord server in the discription. There is a channel the called SCARA 3d printers.
@@conorstewart2214 this is true. the sag just creates a relative perspective that the world is slightly tilted. so bed leveling would solve all of that.
@@3D_printer_guy marlin? Then what control board? Haha 😆 I got excited and like to build one. Can it go any faster? Maybe can use for other purposes apart from 3D printing. Keep up the good work and thank you for sharing 💕
140mm/s is the limit. It is on 12v. If i increase voltage and change stepper drivers, i think it can go faster. Trigorilla MCU. Mega2560 chip. You could mount a laser, or other things. That would be cool. I have a Discord server if you have more questions. Link is in the discription.
@@3D_printer_guy Hmm, input shaping would be tricky because the resonant frequency varies with the elbow extension. But it would be awesome if it works. Even at 30mm/s on my SCARA I can see some ripples at sharp turns.
@@3D_printer_guy hi I'm trying it on a large scale arm length is 1meter. I want to know how x scara homes and how to set up the print bed. The main issue is x homes and x rotates 90 degrees when y starts to home and y end stop works only when x finished the 90-degree moves after x stops the movement, y homing is done but after that, both x and y rotate very slowly, and when I press x endstop both stops. is it possible to have a video call to discuss
I am not quite sure. I had 100x100 build plate on the firmware. You can define what you want, but the arms are 98mm long, so you have to stay within that. I think maybe 200mm tall. I will build a new one soon, maybe i can show you then.
@@3D_printer_guy that 3d printer is very interesting, i suppose you could also move it around since it just prints on a table top then if you have a big enough table you could make a massive print
this is exactly what I am trying to make, awesome!
I am starting a build series if you are interested.
This is beyond interesting wth
Nice work.
Thank you. 😁
I could sit and watch that print all day! thanks for printing a true X,Y,Z cube as opposed to the X,Y,N cube
cool machine!
Thank you. I will be doing a build series on it. 😁
@@3D_printer_guy Then I shall subscribe!
@@AndrewAHayes thank you😁
What hall effect sensor did you use?
I was expecting I would have to make one from scratch
never mind found the answer on the github page
carbon fiber rods everything! that would make for a light weight XSCARA robo armo
I totally agree!

This is a design i found online. The x-scara. It was a fun project. 🙂

Wow! That’s cool. What’s the software to drive that? I like to built 1 too. Thanks
I have a build series on this printer. I use Marlin2 firmware, but it is not perfect.

I think it'll be worthwhile tuning it for high speed
The designer of the HALO SCARA 3d printer is working on getting klipper for scara printers. I think that will open up alot of opportunities.

How to make G-Code & software used?
Marlin 2.0 mpscara. 😁 But i hear RRF is better. To make gcode, you use a slicer. Cura for example.
Hi I'm also trying x scara 0.4 beta but I'm having issues in homing can you help me with it
What kind of issues? Look at the Discord server i added in the discription.

how big could you make something total?

@@3D_printer_guy I suppose the build area would also be in a curve if you would have the arm Completely stretched out
@@OclateGaming Yes. That is correct. You have to define the printing area within that curve.

put these on Boston Dynamics robots instead of rifles
That would be cool!

I used marlin2. My next scara will be with reprapfirmware.
@@3D_printer_guy sir I need your help
There are alot of people that can help in this Discord server. discord.gg/rolohaun-3d-946191040682008666
@@3D_printer_guy sir give me your email id please....
Sorry im not comfortable with that. However you can find me on Discord on rolohauns server.
This confuses me so much
Thank you for the comment. I love the scara kinematics.
@@3D_printer_guy I do too now :)
