Disable auto reset on UM2+

Recommended Posts

Posted · Disable auto reset on UM2+

Hi folks,

 

I'm looking to disable the auto reset that happens when you open the serial port on my UM2+.

 

On the other printers I've got it was a simple case of removing the capacitor on the DTR line of the FTDI chip and then I can send commands to the printer and read back the status while printing from an SD card.

 

Is there a similar capacitor on the UM2+ that can be removed?

 

Cheers

 

Jamie

You mean if you connect the USB part way through a print it will halt the print?

Yes, if I start a print from the SD card then during the print I open the comm port to send a M27 command for example, the printer resets.  I would like to open the comm port during a print to send commands without the printer resetting.
