The Watterott ones I have are “wired” for the RADDS.
@xebbmw Yes, you have to wire a dedicated CS wire to each CS pin of each stepstick. What RADDS pin you tie them to is up to your choice, as long as the pin is not taken by anything else. A good choice is the extension header on the side of the RADDS (long row of pins on the edge).
Very very nice.
What if you have e.g. two z-axis?
@xebbmw It can accept as many or little drivers as you need.See my demo video with the RAMPS - I'm only using one TMC2130 on that board, on X.
@xebbmw I like the idea of a shield for Due that can support these "smart" drivers natively.One thing that would really be nice if it would also support other variants in Trinamic's range, the UART based TMC22xx series.
Here is a video of the sensorless homing process in action on my CoreXY platform.
@nightdemonx I’m also having some issues building the latest developement branch. I’ll figure out what’s wrong and send you a working config.Some baseline checks: for CoreXY steps-per-mm and feedrates should be the same on X an Y (if you have the same type of motor). Do you have different ones?
@nightdemonx Thanks for posting the picture of your setup. Would it be too much to ask for another pic with the fan out of the way. I can't really see the wiring well enough in your current picture.
Hi all,I've managed to get the printer to move with the TMC2130's on RADDS.However I can just get them to move the first bit, as if my speeds are too high. I'm only using X and Y for the trinamics because my Z axis is a dual axis leadscrew where noise isn't an issue.How high would you set the current in the repetier 1.0.0 dev version? I'm already up to 3000mA but I'm afraid to go any higher...Do I need to tweak the potmeter on the board as well? I think I wired the bottom of the radds correctly because the drivers do work.VideoI hope you can help. otherwise: great work Alex and Repetier
@alexsomesan I am trying out your tmc2130 implementation on my Mega-driven delta...when I run the steppers in StealthChop I can't get it to work with normal speeds (I am using the current settings I was using with marlin (which worked there)).It seems as if the motors are stalling, even if I remove the delta-Arm so, there is no real load to be lifted.They sound as if they are constantly missing steps.when I trigger the endstops by hand (I'm not using Sensorless homing) and it does the second, slower-speed homing, they seem to work fine.Do you have an idea what could cause such an behaviour, or with which settings I could play around with to resolve this issue?Thanks for your great work!@Repetier Is this the right place to ask such questions, or should I be writing private E-mails?
