I’m considering building a 5 Axis cnc machine and am completely stuck when choosing the right board. Well, I basically built everything allready but now the electronics are the next step.
As an example, the 4th and 5th axis will be moving like this: https://www.youtube.com/watch?v=wTh0wofb5_w&t=348s
With two steppers for the z-axis and one stepper motor for the x and y-axis, I will end up with 6 stepper motors…..
Actually, I am considering a RepRap Rambo 1.4, but am not sure if it would actually be working as the I/O slots are named x,y,z and E0 and E1… no idea what the E stands for. Any help/suggestions prior to purchaising the wrong board and ramps is highly appreciated!
Thanks beforehand!May 2, 2019 at 10:33 am #99046
I would start with a CAM package that can handle 5 Axis and see what and how it outputs it’s code. That is going to be by far the most expensive least flexible component of that endeavor.May 2, 2019 at 11:04 am #99049
The FYSETC F6 board will give you enough steppers to do 5 axis, but as Ryan says the hardware is by far the easiest part. 5 axis CAM software is pretty pricey.May 2, 2019 at 1:58 pm #99064
Why you need two independent z drivers?May 2, 2019 at 2:16 pm #99068
Thank you all for your fast replies!
@Ryan: First, I am using Fusion 360 as CAM software as it is for free (for hobby users like I am). I know it is not as sophisticated like AutoCAD/CAM 3D or Inventor, but it works for me.
Additionally, Fusion 360 produces G-Code as an output file that is compatible with arduino boards. At the moment, my Arduino Uno and a GRBL v3.0 CNC Shield works fine with 3 axis; However, not compatible with 5 -Axis. That is why I first asked about the RepRap Rambo v1.4 board.
@bill: Thanks alot for the advice!
@guffy: I followed the setup of my 3-Axis system of the RAW 1.5 machine. When you google it, you will find it quite quickly. As it turned out, when I have only one Z-stepper motor, the entire system gets a little torque, tweek when using only one motor on one side, despite the fact that I used aluminum for the frame. It is most likely because the main difference from the Raw 1.5 to my machine is that I am using sliders and not wheels, spindles and not belt drivers. There are definitely easier solution, but as I cannot bring both Z-Axis cables (left side and right) into the same slots of the GBRL cnc shield… they are too tiny… I need to use two slots.May 2, 2019 at 2:19 pm #99069
You can wire it sequentially or in parallel

I think we need to develop a new internet standard of practice that involves fair warning when posting a rabbit hole like that ; )
Wow. My mind is going a billion miles a minute here….May 3, 2019 at 2:09 am #99111
Well, when you take the red pill and stay in Wonderland you’ll see how deep the rabbit hole goes! … this guy definitely took the red pill 🙂 … but his construction of the 4th and 5th axis, though… Staying curious is all 🙂May 3, 2019 at 2:38 am #99113

the problem (as stated) isnt really the driving of the 5 axis, or even the building of a hobby spec one… the probem is getting some computer software to give you some g-code or whatever to drive 5 axis. My friend does 5 axis machining at work daily, and the software they use is horrible but theres just nothing good out for 5 axis… and thats on a million dollar machine… as far as i know, there is no real hobby level 5 axis software option?
i could be wrong, havent looked for a long time.
p.s. e1 and e2 stands for extruder 0 and extruder 1 as thats what they will most likely be used for in the 3d printing world (for which the PCBs are designed)May 3, 2019 at 7:43 am #99127
Well, I use Fusion 360…. its okay… autocad would be better!May 3, 2019 at 7:58 am #99130
