Hi, i want to share my experience and i hope my English will be enough.
i buy a lot of TMC2100, from a lot of different suppliers. I finally found in watterott the right one. White PCB all the times was chinese 2 layers driver and they come ALWAYS forced in 1/16 stealthchop(standalone mode forced with a resistor. source watterott support by mail), if not they are not able to manage the current due to the poor quality and also have a dual logic voltage (3 and 5 ). According to datasheet the dual voltage logic required a sequence for the power on and power off, if not they will work in a wrong way. Watterot also sell a 5v version that is good for RAMPS and similar (MKS ect..) and don't need any attention, like others drivers.
When i try to change the setting of a white pcb's driver i also feel something different, i don't know why but in fact the are working (forced) in stand alone mode so no way to change that. I finally buy the blu pcb version and set as 1/16 spreadcycle, not quieter as the sthealth chop but i set back the acc. to 2000 and jerk to 15 with no loose steps. The best will be pilot the 2130 by the serial IPS, supported by marlin but without a documentation..... they can change between 6 different modes and also change decay by gcode while printing so you can manage silence and torque in according with any single movement of the tool-head... hope someone will make it possible.
i also try the 2208, that use the stealthchop2.... is a bit better but no way for me to set the acc. over 650mm/s or i will loose steps on my heavy Y buildplate.
But the biggest problem come from the controller, 8 bit is not enough to use a real 1/128 microstepping but most of the 32bit board have not the same stuff/comunity_support/price as a ramps 1.4 or an all in one like the mks gen 1.4. I bought a RADDS but no way to have working the same solution available for the ramps.... hope to see some small project come to real product like the piccolo_3d board.... sad that the alligator 2 will never see the light....
