  Hi I was wondering if you will be selling any pre-assembled versions of this board as I would like to trial it for a new Delta design I have been working on?

  All the best,

  Dave

  Hi, sorry for the long time to answer. It took some time to get these manufactured. Pre-assembled boards should be available at our Distribution channels, e.g. Digi-Key by beginning of December.

  hi jonas,

  i’ve ordered and received a TMC5130 eval board and have been working with it for a couple of days: i have the M119 command implemented. as a software libre developer and advocate i do NOT use github so i will not be logging in there. i will however be happy to publish a git repository of the full source code including the modifications that i’ve made on a libre-hosted server.

  i would like to talk to you – publicly and openly – about getting the TMC5130 up and running: can i ask you the favour of joining forum.reprap.org so that i (and other people) can interact with you and other engineers from trinamic in a way that other people may learn about the advantages of the TMC5130 and the modifications that you’ve made to the marlin firmware?

  i absolutely love that there’s clearly some synchronisation in the interrupt service routine (ISR) in stepper.cpp, and the fact that you’re using SPI to communicate with the steppers is a huge technical leap forward over using 8 to 16mhz microcontrollerst that simply can’t cope with proper synchronisation.

  however i would like to know how to reduce or set the micro-stepping rate, how to set the current levels, what the default microstepping levels are, what the default current levels are and many many other questions which, really, if you are going to the trouble of telling one person you might as well tell everybody, so that the open software and hardware community get to see what’s going on, gain confidence in the fantastic work that you’ve done and *want to buy your product*.

  and the best way to do that is for you to join a public forum and engage with people on it. i am happy to work with you to make that happen, do feel free to email me.
