So it seems that maybe more lately that my print times are signifigantly longer than the "build time" shown in the software. An example, I have a print which said it would take 1 hour 28 minutes and I'm now 2 hours and 40 minutes in and it's only at 58%. I don't recall this doing this before but to be honest I never paid attention until recently when things seemed to be taking way longer than the estimate. I have a maker select v2. I was playing w/ print speed since I don't care so much about the finish of these pieces so I increased print speed from my normal medium print speed of 100mm/sec to 150mm/sec just to see what would happen. To my surprise it printed fine (A bit rough). I printed via SDCARD. I wonder if something in the printer is throttling down the speed? I don't have a trained enough of an eye to determine the actual speed it's printing at but it cannot be 150mm/sec. I've included the first 1.386 lines of gcode as the entire file is too large.
Note that until today I printed via USB but the USB port on the printer gave up the ghost. Perhaps there is some sdcard read speed limitation (Not likely) but just trying to come up w/ some rationale for this behavior.
Looking at my gcode it is defining print speed @9,000 mm/min and first layer speed properly @33% (2,970 mm/min) and then back to 9000mm/min for the second layer. I then notice it throttles it back again and I'm not sure why. I do know it reduces speed for walls, infill, etc. yet the time calculation is far different than actual.
