I built several versions of the firmware to try out on my printer with great success. Today I just got a BLtouch and went to build a new firmware and the builder says I'm out of credits. I went to my account page to see if I could get more, and I don't see an option. Am I missing something? I am already paying for the subscription for this service, which doesn't have Ender 3 Pro 4.2.7 support by the way, and there is now a limit to downloads with the builder? Please help me understand this logic. I don't mind paying for someone to work out the kinks with building marlin firmware. I see there is unlimited downloads of this pre built firmware, but not for the builder.
