Control board

What is the difference between the mini Rambo and the Rambo I plan to use my MPCNC to 3D print as well as drag knife and router and possibly add a laser and what ever other options a little later to be able to do it all with one machine but my question is what is the best package you sell for me to purchase to be able to accommodate those options wether it’s tomorrow or a couple years down the road before I get the other parts. And I would also like to try to customize mine to have a sixth and seventh axis to be able to carve sculptures as well, would this be possible with this set up or would I need a bigger control board or some other type of electronics? Thank you

The difference between the Rambo and the mini is the number of stepper motor drivers. The mini has 4 and the Rambo has 5. I recently looked up what it would take to add more stepper drivers and it is possible but not easy. I couldn’t find any control boards on the market with any more than 5 stepper drivers. But you could start with an Arduino board and manually wire up more stepper drivers on your own.

Thank you I was wondering about that. I may have to start off with the Rambo and eventually mod an Arduino to run seven because I would love to be able to do sculptures or more complex parts.

In the selection it has the mini Rambo with series wire kit, Rambo with series wire kit, then Rambo with dual firmware with wire kit. What control board do I order to do any set up I want as far as the laser engraver, CNC, drag knife, and 3D printer and what ever else I might can use it for?

You can do all of that with any of those sets of control boards. Drag knife, laser, router, printer etc.

the only difference really would be if you want to 3D print with dual extrudes. In that case you would need the Rambo not the mini.

And in either case you would probably be better off not starting off with the dual end stops. Just my opinion. But that is something you can easily do later if you thing you need to.

How would the machine perform without the Dual Endstop I have read that it’s a nightmare to set them up.

On my MPCNC I have no wired endstops. I have physical plastic endstops. So at the start of a job I physically move the machine into the corner up against those endstops. Then I hit the home all button. It then locks into place and that is my 0,0,0 position and I know it is square. After that I can move the bit into a new position using the controls. And then I use the G92 x0 y0 z0 to tell the machine the new position is now 0,0,0. Then I can start the job. It works well for lasers, and cnc router. It would work well for a drag knife. Not great for a 3D printer. Z is very important for a 3D printer.

Yeah I used to have a printer I loved it but I sold it to save up money to get me this machine. Is there any tips you might have I haven’t ordered my machine yet but I can’t wait to get it.

Do you have any experience with a pendant controller.

Pendant? No sorry. I don’t know what that one is.

It is basically a remote control for the CNC so you can move the gantry around easier without touching the computer or the gantry I’m gonna find me one when I get my CNC.

Oh yeah! I saw that online. It’s a gcode sender. I have seen a few designs of similar devices. Cool concept.

Have you found CAM software that can handle more than 4 axis, that doesn’t cost as much as a new car?

 

If you have ever built a 3D printer it is exactly the same. For most it is trivial, for anyone that does not have the experience it can be a lot of unfamiliar things to deal with, wiring, electronics, firmware, flashing, code editing, CAM editing and pre-planning.

 

Hello,
I’m going to use the Rumba plus as a control card and I really appreciated the configuration of the RAMP 1.4 with 1 driver for each stepper motor, the rumba would leave me a slot to also use 1 extruder or a motorized cutter. Is there anyone who uses rumba plus and can tell me or can you send me a Marlin version already configured for this type of configuration?

Thank you

I haven’t looked for a software yet but I was just wondering if it was possible.

I have built an Anet A6 before and will probably add Endstops. Is there any plugin on the board for five endstops cause idk if I’m confident enough to do any soldering, although I would like to learn how to make boards and electronic parts from scratch but I wouldn’t want my first attempt to be on my CNC.

You will have to mod the dual endstop software for use on a Rumba or the FYSETC F6. You will obviously need to change the board type but also you will likely want to use E1 and E2 as your X1 and X2 drivers and not disable E0 so you can use it as the extruder still.

I want to make a correction. In an earlier post I mentioned turning my CNC into a seven axis unit, what I meant to say was turn it into a five axis unit to allow for rotation of the head to do sculptures and things like that . Sorry for the confusion.

John the problem with that beyond mechanical (each axis multiplies the deflection) is software. True 5 axis has to account for the machine itself (so it does not crash into the work, angles, etc). I am not sure you will find many decent 4 axis choices without too many zeros in the price, 5, I honestly could not name one.

Another interesting board to watch is the Duet WiFi or Ethernet and a Duex add on. There were rumors at MRRF this year that a Marlin port was in the works. If so, you’d have MORE channels than you’d know what to do with!
