I have several 3D printers and use them for business purposes.
One of the things I've always wanted to have displayed (on a separate LCD display) would be Current Time Elapsed Since Print Began, Estimated Time of Print Completion and Print Time Remaining.
Right now, the firmware is capable of displaying the Elapsed Time Since Print Began.
But what I want is a dedicated (extra) LCD display that displays the following by default all the time.
1). Elapsed Time (since print started)
2). Approximate time to Complete
3). Time Remaining
4). Line Number (in 3D printing, this is the program line number)
5). Current Z Position (Print Nozzle Height From Bed)
I understand Sailfish Firmware does have Time remaining as one of it's displayed parameters, but I'm hesitant to change my firmware for fear of "bricking" my printers mainboard.
I'm just beginning this project so it may take a while to even find out if it's possible.
If you have any information that might help please chime in.
