I installed the most recent released version of Octoprint on my Raspberry Pi B+. Everything seemed to be working fine and I was printing some parts that I got from Thingiverse. Up to this point I was using the SD card transfer method and printing from SD.
I have a Monoprice Mini Delta.
I tried printing a part through Octoprint that I had previously printed with the SD Card transfer. I noticed the Cura estimated print time was about 1.5 hours. When I started the print on Octoprint the estimated time, after stabilization, was 7.5 hours.
The printer came with a test part, small cat, gcode file. I copied this onto an SD card and printed it, it took about 1 hour. When I upload the gcode to Octoprint and print it, it takes 6.5 hours.
I looked at the gcode commands on ther terminal screen. It doesn't look like there are any lost commands where the printer requires them to be resent.
I have the baud rate set to 250k.
Is the Raspberry Pi B+ not powerful enough to run Octoprint?
