BIQU DIRECT 3D-printeronderdeel Ultrastille stappenmotordriver TMC2130 V3.0 met koellichaam voor SKR V1.3 MKS GEN L Ramps 1.6/1.5 besturingskaart (SPI-modus)

Piacevole ed adeguato l'imballo, non avendo ancora utilizzato l'oggetto non sono in grado di fare alcuna valutazione funzionale.

Habe die Stepper im BTT SKR 1.4 eingebaut um die Fahrgeräusche des Druckers zu minimieren

I went through two separate batches of these BTT/BiQU TMC2130 drivers. In theory they should work well, silent and fully configurable via software given their SPI interface.I had a working machine and felt the time had come to upgrade to the 32-bit world so went for a BTT SKR1.4 board with BTT (BIQU) TMC2130 drivers. Granted changing two major components (main board *and* motor drivers) complicated the debugging (I wasn't happy with the BTT SKR board but that's a separate review) but I had to come to the conclusion the drivers themselves were faulty/defective.Initially my machine was a 12v powered RAMPS board with 8825 drivers - worked perfectly (but noisily). Changed the mainboard to the SKR 1.4 with these TMC2130s and got constant and random layer shifting in x & y directions. As far as I could tell every layer was printed somewhere different. My printer went from working to simply making plastic spaghetti.The one thing in my favour was I knew the machine was fine so it was not a mechanical issue (e.g. loose bearings or belts) it could only be the electronics.I returned the first batch of TMC2130s and got a separate batch. These still exhibited the ridiculous levels of layer shifting. I tried a different SKR board and it still exhibited layer shifting with the 2130s.The only way I could get anything approaching a decent print was reducing the entire speed of the machine (20mm/s print speed, 40mm/s travel, 100mn/s/s acceleration) which was ridiculous as the printer was easily capable of printing at 100mm/s. However, even then the printer struggled to print anything more than a 20mm calibration cube.In my routling around the internet I found a few (unsubstantiated) comments that the TMC2130s really run better at 24v. Since this was another planned upgrade I had in mind, I took the step early and replaced the power system with a 24v set up.Changing to 24v made absolutely no difference, still stupid levels of layer shifting. Switching out the TMC2130s for the 8825 drivers I had used in my RAMPS board and (one of) the SKR boards printed perfectly. Therefore, I can only assume the BIQU TMC2130 are, to put it bluntly, rubbish.I suspect (despite ample available cooling) that the drivers are over-heating which might be because of poor board design (thin copper traces, I believe Trinamic recommends 2oz copper); it might be because they did not put in enough vias (or painted over them); or it might be the glue they use to attach the heat sinks being cheap non-thermally conductive?! Who knows. I saw sense and bought Watterott drivers and those work perfectly (but again thanks to poor/inaccurate BTT documentation require a fudge to get working)On the whole BTT/BIQU appear to make "adequate" and cheap products. I think the core issue is their products are too cheap, basically they've cut too many corners. Quality control is a major [problem] area. In researching this problem I kept stumbling across issue after issue where they've mislabelled, mis-manufactured something which either destroys ancillary equipment or requires fudges and work-arounds.I would not recommend these drivers. Having learned my lesson, I would now recommand Watterrott drivers.

Als Ersatz für die TMC5160T Pro bestellt, die in meinem SKR1.3 nicht lauffähig waren (wie sich herausstellte hat BTT im SKR1.3 den Mosi Kanal mit dem CLK des TMC kurz geschlossen...Klipper meldet dann Kommunikationsstörungen auf dem SPI Bus).Grundsätzlich funktionieren die TMC2130 Treiberbausteine. Man sollte allerdings eine gute Kühlung mit einplanen, da bei 1,2 Amps Strangstrom und 200mm/sek Verfahrgeschwindigkeit die Kühlkörper bereits nicht mehr mit den Finger angefasst werden können.
