Never use Smoothie board for obvious reasons, but the config.txt file suggest thing that you can control are very limited.

Why would you never use a Smoothie? It is a 32 bit processor first of all meaning it runs circles around any RAMPS or other 16 bit board. Virtually every setting is available through the config.txt file, even current control for the steppers. If they made one that supported dual extruders for a reasonable price I would put one on my CT'c instead of the X3 pro I am using now. I used the X5 on a delta build and it was the best and most robust board I had ever used. I suggest you try before knocking.

the X5 GT will support dual extruders and with 5 drivers is about $150. They also have an expansion board that will allow you to run a Quad setup as well. The X5 mini will only support a single extruder.

Someone may want it. But you will find most of the folks here are into the Sub $500  up to the $1000 range of printer . Not too many here going top spend nearly 4 grand on an axiom .

I get that, but this is a thread based on the axiom, many many people were wanting that source code now that I went through the trouble of getting it everybody on the thread is quiet. I don't understand.

Okei, I am not completely sure how much have been done since my last post but just wanted to update you guys on what is going on!

Because.. The printer is now actually fairly stable! And looks like this:

This is what i have done to the printer for now:
*New printer head with a significantly improved belt tension compared to the original
*New hotend - Currently using a E3D with a overkill cooling fan (helps prevent PLA and XT jamming) and silicone sock (which is genious! Full blast on cooling without affecting nozzle temp)
*Inductive proximity sensor - If i started over i would use something like Bltouch to be able to probe the glass directly
*Bondtech extruder - unstoppable beast!
*New firmware - Clean version of newest Marlin
*Removed standoffs under heatbed as they bended the bed upwards!
*Using a filament oiler for PLA - to fight Jamming

This is what the printer produces now:

Black and white PLA parts

Black XT parts

This is what could be improved further:
*Improved print speed, if i print faster than what is shown above i get random over and under extrusion - signs of jamming, which is then bruteforced to print again by the Bondtech.
*Using a Bltouch or similar to probe the glass bed directly. The bed is hard to insert equally every time. Since the inductive sensor is not triggered by the bed itself but the metal brace holding it this can mean failed prints due to the way the glass plate is mounted. The braces securing the glass has a rather big radius in the bend which can force the glass further down if not perfectly centered.
*Not sure if 1,75 or 3 mm filament is best.. Currently using 1,75 but haven’t tried flexible filaments
*Shorter Bowden tube is always a good thing!
*Slightly tweaked acceleration settings to get rid of the last ringing artifacts.
