Hopefully someone here can help us…
We have an Ultimaker 2+ that we have been using with success to print PLA and ABS from Cura 2.3 and the latest firmware that was available at the time. Recently we purchased a structur3d Discov3ry extruder, and as part of that installation we had to downgrade to Cura 15 and install a custom firwmare from April of 2016.
This has allowed us to print with the extruder, but unfortunately the older firmware is not stable in temperature control and we are getting consistent temp errors and filament extruder issues. Ultimaker says newer firmware will fix this, and Structur3d says we need older firmware to use the Discov3ry.
Can someone let me know what settings they use to print PLA, using the April 2016 firmware and Cura 15?
