New guy here. Purchased the Dremel printer, and for the last few days things have gone very well. piece of cake to set up. was printing one of the sample files in about 20 minutes. ran into a little trouble this evening printing some cylinders. I printed two, or rather one and a half since I stopped the print as there was no point going any further. I have attached a photo of both pieces. it appears that whenever the extruder head pauses for a second or so at the circumference the blob is generated. any thoughts. going to give dremel a call in the morning....i guess I will find out how their tech support is.

Any help I appreciated
