Hi... will you be willing to give a copy of your configuration file for the K280? I have tried to make my K280 to work with different boards and none work. This would be my last try before I do something else with the aluminum, extrusions.. I would really appreciate your help..
The only config I have is for my Duet WIFI board, which I fitted from scratch: I never even powered up the provided controller, and the printer itself now has double precision steppers, iR level sensor, E3d titan and v6 hotend+pt1000, a whole bunch of mods that take it away from standard. But for what it is worth I've put them here: gist.github.com/easytarget/1a0049a1bf20a8e6ffed5be783fc866c please note the comments.. Whatever board you are using; do it slowly and in stages. Start with movement, get the printer homing and moving as expected, eg it homes all three vertices reliably, and if asked to move 100mm down in Z moves 100mm (eg step counts and directions correct), dont worry about X and Y yet. Then get the hotend heating, and extruding (calibrate the extruder). Then get it probing with whatever height sensor you use. Work out the offset and get it repeatable. Then calibrate/level (with the bed at temperature.. it tends to expand once hot). Then print.. I re-calibrate before every print, the K280 is spindly and seems to drift off calibration easily.
Good Luck! Note that there is a followup board to the DuetWiFi called the Duet maestro; it's cheaper and only for single extruder systems. But it runs the same firmware/controller so the config is identical. Do not forget to halve the steps/mm for the vertices in the config if you are using the supplied (1.8degree/step) motors. And the extruder calibration there is for a Titan (which has a 3:1 gear in it) so you will need to change that radically too ;-)
I'll check it out.. Thanks again...

I'm getting a duet wifi. Thank you for your help help. I'll try to follow the steps you indicated.. Wish me luck.. 😉
Good Luck!
