Your notes indicate that the next step is to drill out the nozzle - did you remove the nozzle before drilling? That is not clear from your description. I guess the hole could be drilled out while it is mounted but it makes more sense to remove it and try a solvent (acetone?) first.

Thanks again for your help.

Geoff - here is an update on the plugged left extruder. I contacted FlashForge tech support and Tang, a very helpful technician, led me through dis-assembly of the print head and removal of the nozzle where we discovered that the small plastic tube was distorted and plugged - he is sending a replacement.

I expect that I will be back in business when that arrives.

Thanks again for your assistance.
