Software Materials Print settings being ignored by printer

I am finding that if I change bed temps on a custom material and watch the head and bed temps on UPStudio (both latest stable, 2.6.x and latest Beta 3.2.x), it was using the temps from the standard materials. I narrowed that down to having to change the material on the machine to match my selection in the software (seems the machine is ignoring the software material settings and using the setting in the machine) but now I don’t know when the material settings are pushed out to the machine. It seems that slicing in the Beta software and sending a print task to the printer doesn’t send the custom material to the printer.

  1. Could someone from Tiertime explain the logic behind this
  2. When is the custom material data pushed out to the printer? I know it’s not when I press print!
