Inspired by Toms video (https://toms3d.org/2017/12/09/tmc2130-guide) about the quiet and sensorless-homing TMC2130 drivers, I started to build this printer a month ago. It isn’t finished yet (cable managament, …) but yesterday I did my first prints and they went very well, even without any printer settings tuning.
I wired them exactly like Tom did, expect the two cable select pins X_CS_PIN and Y_CS_PIN, because I also have a RepRapDiscount Smart Controller connected:
X_CS_PIN from 53 to 66
Y_CS_PIN from 49 to 44
This has to be changed in pins_RAMPS.h (if using Ramps 1.4)
The Z-Sensor is a http://www.escher3d.com/pages/order/products/product1.php which works very exact and has a low building height so I could mount it under the extruder motor near the nozzle. Therfor i added a mounting point to the extruder_strap.
For X-homing I printed a 21mm long cylinder with a 8.5mm hole as the stopper.
The first thing I printed was the yellow fan holder seen in the picture, the second one the 3DBenchy

I have never seen that sensor before. Keep us updated on how it holds up after a few days of printing. I like the concept for sure.September 24, 2018 at 5:57 am #70194
Those 2130s look slick. I really like your mods. Is it still working well?September 27, 2018 at 6:04 am #70510
wow that is a marked improvement on sound. definitely will be looking into these.September 27, 2018 at 6:40 am #70511
The steppers work great but I wasn’t very happy with the motor/hotend mount, so I designed a new one. It’s for the http://www.escher3d.com/pages/order/products/product1.php sensor.

That mount looks very stout. And I am definitely going to try that magenetic build plate. Do I need more than one? Does it’s surface stick pretty well, or should I get some more PEI?September 27, 2018 at 7:10 am #70521
For small pieces I do not use the headbed, with larger pieces I heat up to 40°C, which takes only the same time as heating up the hotend, and PLA sticks like hell. But removing is very easy.
I bought only one, unfortunately they sell only bundles, not only the top plate. But I’ve printed at least 50 pieces, and can’t see any significant wear.
