Couldn’t find any documentation on using the TMC2130 or TMC2208 drivers. Are they supported?
As far as i know you cant de-solder the drivers that are on the board and replace them with TMC drivers. The pins doesn’t match.
But you could use external drivers as step/dri/enable are exposed on the board. You’d have to solder pins or wires to those pads and attach to something like this; https://www.reprap.me/stepper-expander-x1.html
Should have clarified. I’m using a cohesion3D ReMix board. It has support for stepsticks. Was wondering if Smoothieware has software support for the TMC2130 or TMC2208 drivers. Specifically configuration over SPI / UART.
There is support for the TMC26X SPI in the advanced driver control. The newer TMC chips changed the SPI protocol and register size, so you would need to write a new advanced driver control plugin based on the TMC26X one. Serial control is not currently supported, but you could probably add it if you could find a spare uart, or use the soft uart driver.
@Wolfmanjm thanks. So not supported right now. Any chance of support being added soon?
How are you using TMC2130s? I thought I saw a post where you said you had used them. Or are you using them standalone?
I am not using them and I don’t have any so i won’t be adding support for them. If the chip has external jumpers then you should use those. Maybe someone who actually had these could add the support for them. But I wouldn’t hold your breath waiting. Maybe you should ask Cohesion3D if they will add the support?
Oops, gonna need it soon, too. I’m cheaping out initially and waiting for an AZSMZ board with stepsticks. Might look into adding support, sounds fairly straightforward from what @Wolfmanjm says.
@raykholo weren’t you using TMC2130s on one of your printers?
@Wolfmanjm would you be interested in doing so saying you were provided the drivers/board? I get asked quite often if we support 2130’s like Marlin and it would be awesome if we had the support/stall detection.
@Griffin_Paquette I would consider it if I was provided boards and paid for the time spent. It is not something I am particularly interested to do as a volunteer. I do agree support for 2130’s would be nice and I have tried to get others who have a vested interest to do it, with little luck so far.
I’d imagine, as TCM drivers will be used on smoothieboard V2 according to the blog, that some effort would be put into supporting those drivers in smoothieware?
I use tmc2208 silent stepsticks in my c3dmini k40 laser. They just plug in, nothing to configure but the current adjust.
I bought the good ones from digikey. The eBay ones made a weird clicking sound and died a early death.
@Alex_Skoruppa I was thinking of using the TMC2130 - Marlin 2.0 has options for configuring it on the fly. Asked the question to understand if the same was possible in Smoothie. Looks like the answer is “not likely”
TMC2130 now has a Pull request that needs testing… https://github.com/Smoothieware/Smoothieware/pull/1315
Cool. Unfortunately I went ahead with TMC2208 instead.
@Wolfmanjm I’ll gladly get a board up and running for testing this.
If this code works, which by the comments it seems it does, do you think we can get direct stallguard support for full feature set use?
There is a pull request for TMC2208 that needs testing https://github.com/Smoothieware/Smoothieware/pull/1329
@Tiago_Almeida is it pushed to the official Smoothieware Firmware.bin?
Not yet, this needs to be tested first, if you have TMC2208 drivers, test it with my PR code and provide feedback
@Tiago_Almeida can you share a firmware.bin file. I’m not confident I can compile properly
