Page 75 of the TMC2130 datasheet shows a nice graph of what their dcStep function does, and how skipped microsteps look before the full step skips. It shows the drive slowing the motor to prevent major skippage and give the motor time to (hopefully…

I remember seeing the Mechanduino project a while ago...I like it, but I don't think it communicates positional errors to the microcontroller so it doesn't know to slow the other motors...I don't know that I'd call it good for a 3d printer...maybe j…

I could see accomplishing real closed loop control using encoders like this. Using encoders would be a different discussion topic I presume, but might be the same level of difficulty and similarly priced as the TMC2130 driver.Is there a reason why …

This corresponds to what I read from the datasheet. In a nutshell, speeds under 1rpm and when the motor voltage is close to PS voltage. Fortunately, I don't think those circumstances occur often. Most print speeds are around 70mm/s. I'm studying …

Yeh...I've seen (actually made) motors with integrated drives and position sensing. I'm just trying to make it simple/cheap/effective for my printers and mainstream RepRap. Yow, 1.7us is much faster than I thought they were moving. These drives …

@RepetierThanks, very informative! Yes I am amazed how many configurations are supported by both Repetier and Marlin, and Repetier being significantly better organized (and with the web config tool too) makes it much better to work with. I definit…

...well...I guess if I do this I may need to write a special option for different limit switch handling. Or maybe all printers might want to pause and re-home if a limit switch gets hit mid-print? I've had a printer, either Marlin or Repetier to at…

Cool. So I get the jist of the triggering the jam control event, and thanks for your assistance! I do see that 4 of the endstop pins are interrupt pins on RAMPS1.4. I guess I kind of like the idea of using the interrupt pins for D0 on the 2130. T…

@RepetierYes, my goal of this implementation is just to sense skipped steps, re-home, and restart...or initiate a pause or some routine similar to the filament runout in Repetier. I agree...blind testing seems difficult. I'm a mech engineer, so I …

...oh, now I see my ultimaker link at the top...

Hi Guys,I'm just joining this thread, and am seeing a bit of information where some people are testing these with luck: https://ultimaker.com/en/community/17498-new-sss-driver-tmc2130 ...and it seems Marlin has a fork: https://github.com/makertum…

Doh, sorry about my absence...I don't have Repetier forum configured to email me yet (will fix). I will check the code for G92 E0 and see what happens if it's missing.

Doh,I updated to the V1.0 Dev version and everything works great! Sorry, and thanks!Jared

Hi,I've read this feature request and believe I'm trying to do the same thing, for both syringe extrusion and as an out-of-filament sensor, using a standard makerbot version limit switch (3-pin).I'm running repetier firmware 0.92.9 and have modified…
