Hi
I really want to convert my printer to 24 volts, not least because of my stepper drivers/motors (I want to make them quieter). However, I would like to test what impact it has on the drivers before I go all in. (New controller, new heating cartridge, new power supply and so on).
My plan is to use a simple boost converter to generate 24 volts for all my TMC2130 drivers (connect the VM and Gnd of the drivers to the boost converter and the rest of the pins to my RAMPS). This allows me to easily and inexpensively test what impact it has on the stepper drivers and motors.
However, I have two questions. First and foremost, is this a good idea at all?
Secondly, in my search for information online I read the following on Watterotts FAQ:
"At power-up the motor supply voltage VM should come up first and then the logic supply voltage VIO. On power down the logic supply voltage VIO should be turned off at first and then the motor supply voltage VM, because the internal logic of the TMC2xxx driver is powered from VM. "
Should I install a 12 volt delay switch on the power to my RAMPS so that the stepper drivers get powered up first, and is this not a problem on RAMPS in general?
