Thanks for the info picclock! :thumbup: Will have a look at that when time comes. At last they arrived! The idlers made to fit GT2 toothed belts and with a ball bearing in their centers. I ordered them late October and they arrived late last week - talk about slow boat from China .... Anyway, one fitted to the Y movement and the other to the X movement tensioner in prep for assembly as soon as I get the prints ... /Peter |

Hi Peter E They look good, hopefully worth the wait. Are they different sizes ? Not sure if you are into the firmware yet but Marlin have a new release candidate which includes several enhancements that I would think are worth having. Released on 1st December available from https://github.com/MarlinFirmware/Marlin (download the zip). The configuration and adv configuration files contain more information and many more helpful links. Looking forward to your next steps Best Regards picclock |

Hi picclock, The two idlers are the same size (20 tooth) as the drivers to make sure I don't get any unwanted angularities introduced. Thanks for the info about the firmware. As soon as the mechanics are completely assembled and the electronics is wired I will dive into that as well. BR /Peter |

Evening All, I have finally got the missing printed parts, this time they turned up in red so I will paint a few bits black to match what I already have. The missing parts were - from left: - The left end of the X movement - The distance piece between the extruder and the carrier - The distance piece/securing plate for the extruder head - Three end stop holders. It is only the X end part I will paint, the other ones will probably keep the red colour for contrast. As can be seen on the parts on the right, they are printed with a "skirt" to make them stick better to the glass plate on the build table. The skirt is easy to remove afterwards. Interestingly, the red parts are much better fused at print time, compared with the black parts I had. It seems like the colour is a factor to consider as it affect both temp and print speed according to my friend who printed them. Personally I will use PLA for my parts instead of ABS. PLA is supposed to be easier to handle but that will show once I get up and running. Right now it is X-mas preparation time so no shop time in sigt. Have to wait until after the 25th to see if I can get more things done. /Peter |

X-mas eve done (we have our main day in Sweden at the 24th), and everyone is happy and satisfied. :thumbup: So today it is much more calm and relaxed. Managed to adjust what I needed on the X-movement, The toothed belt fitted and everthing in place in the frame. Sometimes it is very useful not to final assemble at the first go. It turned out that I had accidently placed the X-movement motor to the right instead of to the left as it should be :palm: Got the new bits printed but in red this time. So took the chance to use them to contrast all the black bits just for fun. Now the X-movement is complete and also parallell the the build board on the Y-movement. Everything moves with ease without binding anywhere. Time to fit the end stop switches and start the electronics work! BR /Peter |
