Rob your print doesn't look right man. You may be having the same issue i had at first. Try tuning the current on the extruder motor. it may be to hight thats why its skipping. There is not enough filament going through your printer.
I replaced the bed with 1/4" sand blasted glass. Works like a charm. Just make sure to set the acceleration to 300mm/s^2
I also strengthend the y gantry with an aluminum plate. this gave it the stability it needed to reach higher speeds.
I can now do multiple prints with minimal or no bed...
