      Any advise on printing the toolholder? I’ve tried slic3r and cura and man it’s a tough part to print! I’ve had good luck with threads in PLA but this ABS is kicking my butt… It all goes bad on the threads.

      Go slow… Use slicer defauts, but print using hex fill at 15% and stick on a brim of 3mm or so. Also go it at 0.2 layer height. Works on morgan for morgan…

      Thanks Q! I finally got it by going with .2 mm layers and slowing things down. The only niggle was the bridging required to form the bottom of the bore where the hot end seats but I finally got a functional part.

      Now to print a second for a friend here in the states who’s building another Morgan 🙂

      Excellent!

      When I have the farm up and running I will post the slicer settings for each part the way it works for me. If anyone then comes up with better settings, we can update the page.

      Posting settings is a great idea! Some of Morgans parts were a little challenging for me but the process has made me much better at printing.

      Sometimes I’m amazed at the quality that can be achieved with a reprap. But sometimes I’m befuddled by the glob of molten plastic I end up with…

      So, how many bots are you planning on having?

      Good looking prints!

      I plan to have at least four machines in the farm, with another one or two just for playing with my own stuff

      Getting 25 modified DRV8825 drivers tonight. Need some better quality LM8uu or equivalent as well. I have a couple of bad ones laying about…

      Thanks Q! 4 bots sounds neat!

      Yea, I’ve found the LM bearings are hit and miss. I have actually hand matched them to the rods, some will be loose, some will be snug.

      I believe the plastic in them may not agree with certain oils as well. I think I hastened the demise of a few with 3-n-1 oil and I’ve heard that WD40 can damage them as well.

      I have a friend who uses Camellia oil on his machine with good luck. It’s also made from seeds instead of petrochems which is in keeping with the spirit of reprap!
