I ended up recrimping all the cable to connect to a SKR v1.1 with marlin 2.0 just to realize the problem was a cable heat shrink extension on two of the cable motors got used by friction and was creating a bad connection...
stupid me
anyway I now have a Skr v1.1 with marling 2.0 and TMC2208 x and y are working fine but z is shaking and not moving the motors if I set it to step per unit 2500 if I go around 500 it works but logically moves 1?10th of what it should ( for 100mm command it will move 10mm..)
also have some issues with extruder skipping..
I Suspect it has to do with my axis step per unit default max federate and max acceleration...
these are my current settings :
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 2500, 96 }
/**
* Default Max Feed Rate (mm/s)
* Override with M203
* X, Y, Z, E0 [, E1[, E2[, E3[, E4[, E5]]]]]
*/
#define DEFAULT_MAX_FEEDRATE { 200, 200, 3, 14 }
/**
* Default Max Acceleration (change/s) change = mm/s
* (Maximum start speed for accelerated moves)
* Override with M201
* X, Y, Z, E0 [, E1[, E2[, E3[, E4[, E5]]]]]
*/
#define DEFAULT_MAX_ACCELERATION { 2000, 2000,50 , 2500 }
I am using m8 threaded rod with the original dual nema17 for Z
and the V1 aluminium direct drive extruder for E...
any idea
