Re: Trouble with MKS GEN 1.4 and TMC2130

Heya Dmitri, Ok, you may have a loose wire on the thermistor. Check carefully around the can; I've seen them fray right at that point. Checked that, everything is tight... Executed another PID tuning, got again another set of values, now the "jitter" seems to be much less. As for the drivers, I was...

Re: Trouble with MKS GEN 1.4 and TMC2130

Hi Stefan, I am pretty sure it is physically impossible for the temperature to jump from around 265°C to 245°C and back within a second, so I am pretty sure it is the measurement. After tuning PID on the hotend, the temperature got better (more stable). Other issues show up though - occasional drive...

Re: Trouble with MKS GEN 1.4 and TMC2130

Figured it out now - had to remap the pins, to a wild mix of default and "suggested by the vendor".

Now fighting thermal instabilities of the board, the thermistor is jumping +-10°C...

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. It is open on all the drivers. Don't they work without SPI at all if the bridge is open? Or can't you j...

Re: Trouble with MKS GEN 1.4 and TMC2130

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 Regards Richard Hmmm - is MKS Base built differently then? Because it has measurable different v...

Trouble with MKS GEN 1.4 and TMC2130

Hi guys, I received a MKS GEN 1.4 and TMC2130 steppers for it and still have issues I am trying to resolve. Ordered both at FYSETC, plugged in - nothing worked. Every now and then "Driver error" crashes (especially when I went near the SD card), but otherwise - nothing. Replaced the FYSETC drivers b...
