I was able to print an 1.5 hour print perfectly for 1st time in over a year.

I read several topics on here with similar problems and saw a patern in these areas. seems the SD2 at least no matter which RH version. has a tendincy to retract melted plastic to far then it jams just b4 barrel to nozzle in the larger cavity midway. even retreived a peice of filament from there that had musroom head. then as flow stops plasic burns/hardens at orifice or nozzle requiring cleaning from both end using a 1mm nickel silver rod from top and either a #80 orifice drill or .02mm phosfer bronze rod through nozzle end from bottom. rods are available at local hobby shop but costly like over $6 for pack of 6. use great care with the .02mm rods as they are very hard to see yet very hard and sharp and can stab deep b4 you even know it. Kevlar gloves wont stop it either. I done this without removing hot end just heat it up using RH manual controls. clean all plastic out may need to move rods around or twist them to grip plastic and pull slowly out, then use twizzers etc to pull/scrape it off rod (the tiny rod will be imposible to do clean at times so I cut the 12" peices in half and tossed dirty parts like expencive Q-Tips) got 1 of the tiny rods left. and only 1 or the bigger ones got bent in use. still cheapest fix. now I can print while trying to make funds for upgrades. just wanted to share my fix with the group.

thoughts anyone? Mitch

I think its time for a new hotend assm with original .35mm nozzle the SD2 came with. I dont have the money or desire to do mod upgrades on it now as a new better featured printer can be purchased for less. I just want it to work like it did b4 the bad roll of filament done it in some how.

Tim unless I missed alot the last year I think your the one to help here? dont you sell a new hotend that is a drop in for the original Solidoodle and cheaper than the V6 thing most upgrade to? I am only going to use this old Solidoodle 2 for small ABS prints and maybe some day get a better printer with duel heads, multi material use etc.

I got people wanting my tiny vehicles and cant print em yet.

missed everybody here but been busy with lots of things around the home and health issues etc so had to put the Hobbies on hold a while. lots to catch up on. anybody ever buy the Solidoodle inventory? I could use some of those parts at a discount.

is the China clone of Makerbot still cheap? or is there better printers at low cost now?
