| Building a 3D Printer, RepRap Mendel Prusa2 by craynerd |

Seems strange that Alex... what happens when you play with the e-step value as it prints? Chris |
| raynerd:
Just to re-coup a little money on the cost of building the machine, I`m currently mid way through my Prusa Parts print...I`ll be hopefully selling it soon. If anyone wants a parts set to build a RepRap let me know - I honestly believe my prints are very good now. Chris |

Hi chris Problem found. I was over extruding and the nozzle was off square to the bed. I set Sprinter up to print the cogs for the 1st parts set I made you. Forgot to set it back. doh ! The issue with the sides was the filament oozing over the edge because it had nowhere to go. Add in the angle the nozzle was at and it made a real mess of the finnish. Prints are now as good as they should be, even with 3 shells. Alex. |

Nice one Alex. I must admit, I had a little issue with under extruding over the last few nights. The chaps on the IRC channel were insistant that it was filament slipping but I knew it wasn`t. I installed a fresh copy of Marlin, the pre-config one for Prusa running 1/16th step Ramps 1.4 and it now runs fine again...so not sure what happened there. I have recalibrated the axis and I`m back up and running again now. I really like the Prusa and the prints come off it just perfectly. However, I wonder for rigidity and stability if the mendelmax is perhaps a better machine. I don`t believe the prints are any better but I do think perhaps it is a little more solid looking and reliable. Anyway, glad you are back up and running. I`ll send you a link to where you can see us using the parts shortly as we are doing a school blog of the entire project. Chris |

:proj: :ddb: ok I've bit. been reading this thread with interest.nearly finished my worden grinder and needed a new project. After seeing quality of parts chris and others are getting out of these I've gotta give it a go. Got the basic hardware components and a printset ordered to make a start. Matt |
