Re: Trouble with MKS GEN 1.4 and TMC2130

oncerning Thermal OT issues on the Fysetc and BQ 2130 it's due to their board design compared to the watterott one they are missing the thermal break through like shown on the Picture the 4x5 holes in the middle of the pcb where the heatsink is to be mounted. That's why for the chinese 2130 it's rea...

It's a Tevo Tornado, with 24V, so the fan options are limited. Trying to find a calm but powerful 24V 40mm fan is not that easy...
Just a simple buck converter to step down 24V to 12V for stuff like fans LEDS and stuff like that might make it easier

Re: Trouble with MKS GEN 1.4 and TMC2130

Tried Marlin 1.1.8 and 2.0 (not the "bugfix-" versions). Will try the bugfix versions on the weekend.
2.0.x there is only the bugfix version as 2.0 is not officially released yet

and got a huge surprise, since all of the pins of every motor were powered with 24.4V.
That's not a huge surprise that just what you would expect if you are running a 24V system and chopper mode drivers

Re: Trouble with MKS GEN 1.4 and TMC2130

As you are saying with and without SPI. The mode is not just switchable by plugging or unplugging SPI cables. For SPI mode the SPI solder Bridge has to be open for standalone it has to be closed. Which Version of Firmware are you using. For getting into the TMC world you might consider to start with...

Re: Yet another TMC2130 problem

First as you are saying you got TMC2130v1.0 I assume you have either Fysetc ones. I they would have at least cloned it 1:1 from the original watterott desing would have prevented my a lot of headache getting People to explain what is the issue with misconfigured CFG solder bridged, missing thermal b...

Re: TMC2130 on a Ramps Plus2 (Alfawise U10)

With the latest Marlin bugfix it's not required to use the MISO,MOSI and SCK Hardware SPI Pins anymore. You can define Software SPI Pins in the Firmware to avoid Problems of These are covered by your LCD connector which is likely on any Display with an SD Card Reader as thses 3 PIN are used by the S...

Re: Problem with ATX PSU for RAMPS 1.4 with Heated Bed

Is your ATX labeld Haswell compatible or Haswell ready. If not and by your issue description shut down as soon as a higher load is drawn you might have issue with an unbalanced 12V rail. Especially an issue with older ATX pre 2014

Re: 5V fan-suitable output on RAMPS

First of all to get 5V on the servo pins you have to set the VCC GND jumper on the RAMPS. If I remember correct the recommended continious current on an outpot pin for the Arduino and thats where your servo pins are powered from is 20mA with an max of 40mA. The overall current drawn if the Arduino i...

Re: TMC2130 V1.0 Question

Usually you set the Z driver to a higher current as you are driving 2 Motors from one driver. So if you connect only a single Motor for testing check current on the driver.
