Hello Velleman forums
I recently bought some genuine tmc2100 silent step sticks to quiet down my printer.
I have installed them and adjusted the voltage to 0.8v, like suggested and worked my way up. The motors should start moving freely at some point, but that's apparently not the case here. I made all the necessary adjustments in the firmware (change direction, half the steps/mm) but it still doesn't go smoothly and it makes a very high pitched noise.
Has anyone ever installed these drivers on their k8400 and if so, how??
Thanks in advance

Follow those instructions: https://ultimaker.com/en/community/11571-step-by-step-installation-of-silentstepstick-drivers-on-umo

You need to actived spreadcycle mode of the tmc2100 board because the steahchop mode has not enouth power for 3D Printers.

And most important: Install a proper active cooling, the tmc getting very hot.


I use the new TMC2208 Driver, they working "out of the box" and most important in stealth chop mode. The Fans of my printer are louder than the mechanic.
