Trinamic Drivers

Post by Mochanic » Sun Dec 02, 2018 7:39 am

Can we use a Trinamic driver such as the TMC2130? I have been reading about these and they are simply amazing!

I have not used them, they have all the bits in the right spots but configuring them is beyond GRBL on the current Micro. IT needs SPI pins to configure...

It appears there is a way around that.

That looks really nice.
On some place I read somethig like this about Pi CNC Board:
Offloading realtime issues to the ATMEGA controller while doing more complex things on Rasperry.

Controlling the TMC fromout the Raspberry (SPI) could be something in this prospective...

Yes, it can be done. But will need software for it. My question is how often do you change your microstepping with CNC.

I'm still holding off on buying the 2.60 board in hopes that you release an updated model soon, and what would make that even better is if you were to include support for the Trinamic TMC2130 drivers! Seriously, it's time for to implement them already...

What features would you like to see?

My understanding is that the Trinamic can be setup via SPI....

I need to consider having compatibility with older drivers as well.

People WILL buy whatever drivers you build the board to work best with, why be concerned about compatibility with old outdated drivers? If they want super cheap they can continue to use what is already available, but looking forward I would like to see all the latest and more powerful electronics implemented. MANY people are already pushing the limits of what these electronics can handle, so why not come out with something that a much broader audience can implement into their projects?

Pi 4B 4GB (This is going to be HUUUUUGE! You should jump on this bandwagon asap!)
Trinamic drivers (This should be the new standard, forget about the old dinosaurs)
5 axis standard! (3 is limiting your customer base big time!) Maybe 3 onboard and up to 5 via an external module?
