I have a helpdesk ticket ID 165207 where the customer is setting their initial layer temperatures at 200C and then tries to get the following layers up to 230C, the settings they have are correct in Cura (picture of settings attached)
Cura is not setting the lower temperature to start the print, but instead going straight to 230C. We were able to duplicate this in tsr.
We also tested on Cura 3.2.20 and it had the same problem of not keeping the initial layer temperature changes. We also tried changing the default print temperature and it was still overridden by the base printing temperature.
Customer is using Windows 7 64 bit
