6 AXIS, X,Y,Z,A,B,C and 3 extruders

HI All,

i am asking around if anyone knows how to edit the current MARLIN firmware or whatever firmware to allow true 6 axis control,
in the sense, each axis will have a homing min and max limit.

the standard X,Y,Z and added A,B,C , the extruder E0,E1,E2 will still be available for control.

Anyone done this before?

thks
Sincerely,
Conrad

HI Anyone have any advise on this??

Maybe take a look at the Smoothieboard and it's associated firmware: [smoothieware.org]. Marlin is fairly optimised to run on limited hardware, so may be difficult to expand. Smoothie firmware, however, has a more modular design, so it should be simpler to uderstand and modify. It took me about a day of reading through the source to piece everything together. There's a good explanation on the website on how the firmware works. You can also ask on their irc or ask the creator directly via email. For the hardware you may get away with using the broken out GPIO pins on the Smoothieboard. If that's not possible or desirable then you can build a breadboard version instead: [smoothieware.org].

I hope that helps,
Sam

hi Samp20, thanks for this.

will definately look into smoothie, however i think arduino does have the hardware capability to control multiple steppers.
There is this project called Decapede where 10 stepper drivers are driven by a single 2560

I'm not sure what happened to Decapede, back in March it was prototyping with talk of a crowdfunder, but I haven't heard anything since. You might PM Simba to see where it's at.

Personally I think with that many steppers it will be stretching an AVR past it's limits, so I have been working on ARM based solutions, and they should be compatible with 5V electronics as well.
