On thing I would love to see in the software (I’m using Pronterface) of the future is to be able to “back up.” Sometimes I have a print fail due to the plastic no longer depositing right, or some other malfunction. It would be nice if I didn’t have to toss the piece, but instead could hit the “emergency” button and then tell the machine to begin stepping backward until I told it to begin again.
I’m not specifically saying it has to retrace all previous steps for each layer. Just being able to go back down the Z axis until it was close would be great. It would know what layer to start printing again by how much I had allowed it to reverse, and we’d hope that the 1/2 finished layer was “close enough” to not cause a problem.
