Between my Kossel not working reliably and my Ender 3 doing an impression of a rock, I was at a crossroads. The Ender3 has intermittent and frustrating extruder problems, so I want to get rid of the boden setup and swap it with a direct drive Titan Aero clone), but that requires a new mount. My Kossel has been acting weird for months with layer shifts, so I could not use it to make the parts for the Ender 3. Yep, both my printers suck. Hopefully that will start to change though since today I did a motherboard transplant on my Kossel. It now rocks a 32 bit Re-ARM and RAMPS 1.5 board, with Marlin 2.0 providing the magic sauce, and best of all it works (though not without the now expected pain and suffering).
Aside from almost cutting my pinky off, I bought some stepper extensions that I did not check closely. Normally I would not consider stepper extensions to be a problem, since how can somebody screw up 4 wires and 2 connectors (he, he), but mine were mis-connected. The result was steppers that did the boggie but not much else. I also had a problem with the display not working (lit but would not show anything). I just had the wrong display defined in the Marlin configuration.h:
Had this:
#define REPRAP_DISCOUNT_SMART_CONTROLLER
should have had this:
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
Got that fixed and it works great. What is most important to me though, is that I got all axis working, endstops are endstopping and themistors are thermisting - and the heaters work too, so all the important systems are go.
Since I did not want to have this mess of wires are electronics flapping in the breeze I was able to salvage several failed prints to make a sort-a enclosure for it all. The fans are all tired into PSU now since previously I was too lazy to take apart the PSU to connect them in. Once I get this calibrated, printing an enclosure will be at the top of the agenda, well after several other projects that have been piling up.
This is running Marlin 2.0 and I am just using the original drivers (A4988) which I've connected to TL-Smoothers. Now that I know it works I am going to order some TMC2130 drivers since they should work with the Re-ARM (which is pin limited compared to the Arduion Mega).
