  1. FYI - It's been a while. Update on 'power surge' - seems I had 'blip fans' set to on in S3D...That was all it was :)
  2. More information... I started a new print this morning and when the 'brown out' happens, the fan icon on the display disappears momentarily, then comes back on, off, on again and remains steadily on until the next 'surge event' happens. I've been running TinkerGnome's firmware for years with no problems...don't think that has anything to do with this issue.
  3. Hey guys - I'm hoping someone can shed some light on an issue I'm having. The power seems to surge randomly during a print. The MeanWell 24v PS doesn't seem warmer than normal and I haven't clamped and tested voltage at all - just observation. I don't remember...are the fans on the head (hot end & print fans) 12 or 24v? Here's a video of the problem: Does anyone have any tips for diagnosis or is this a somewhat known issue that happens over time? Any help is appreciated! Thank you!
  4. @yyh1002 Yeah pretty sweet...Just waiting on a few more parts and I'm joining the Mark2 club Nice job on the mods. I just downloaded them for when I'm ready. Thanks!!!
  5. I'm playing the waiting game on parts...I want to use the same style feeder as the UM2+, so there's one on the slow boat from China via Ebay coming at some point this month. We'll see! I have a bulldog feeder laying around but it's huge compared to the stock UM2+ geared one. Once it arrives I think I have to make it into a left (or is that right?) configuration for the 2nd head. Thanks to GR5 for the Mark2 upgrade goodies & Fabrc8 for the UM2+ fan shroud (replacing the original UM2 shroud) I upgraded to a Olsen block with the original head way back with a GR5 heater, so I'm goo
  6. On paper it seems like an elegant solution. However you have to consider that vertex color information is only possible in select 3D mesh formats. There are not many CAD packages out there within the grasp of most FFF printer owners that have the power to color vertexes with any kind of reliability - and within budget. Most have a hard enough time just getting their mesh to be water-tight. Furthermore, once you start sharing a design or people remix it to change holes sizes etc, it's another opportunity to mess up the vertex coloring, assuming the original author's was right/good to begin with
  7. Thanks - I made the mistake of resetting my S3D when I upgraded to 4.0. Since then at the end of the print, the machine just stops, nozzle in the material still and the LCD and LEDs go dark like the thing crashed. It's done this on both short and long prints...so I think it's the end script. Here's the original end script from S3D: G28 X0 ; home the X-axis M104 S0 ; turn off heaters M140 S0 ; turn off bed M84 ; disable motors Not sure why it isn't doing the G28... I just copied/pasted @jockspice end script so hopefully that does the trick
  8. Thanks! Doin' it. I can't seem to locate in Step 6, the referenced "Chiz' cheat sheet" somewhere in this thread...Can anyone point me to it? (or just reply with quote of the post) EDIT: Chiz Cheat Sheet from May 24th HERE: (Click on chiz replied to a topic to go to cheat sheet)
  9. Hey I want to play too! I've been busy with other things and haven't kept up with all the latest toys. I just stumbled upon the Mark2 & WOW! I am excited. I already have some goodies left over from the UM2+ upgrade, like the original hot end stuff with Olsen block installed. I just ordered a Mark2 board from GR5, official UM2+ fan shroud from FBRC8 (USA) & have a knock off UM2+ coming at some time from China on order. I *should* have everything else. I have no need for multi-color extrusion. My main focus is trying PLA support filament. If I could get this worki
  10. Trying to download Cura v3.1 & getting "500 Internal Server Error" 12/7/2017 3:00 PM EST
  11. Use the Tweek At Z Plugin in earlier versions of Cura or in Cura 2.4+ Extensions->PostProcess->Modify GCode and select Load Plugin & Tweek @ Z 5.1 from the list. Fill in the parameters and let it recalculate. Then save. Done.
  12. Never-me mind, I found it after I posted thanks anyways:) Under Extensions: Post Processing: Modify G-Code -> Add The Script Also was looking for this...Thanks for posting the path! Making switch from v15.0.4 - keep going back because I can't find where Tweek @ Z is!
  13. A special 'Thank You' to Erin and the rest of the crew at Fbrc8. They went out of their way to proactively take care of me. I know where I'll be getting my UM3 when I am ready! Thanks!!! WiseOldOwl
  14. The 'stock' bushing are fine for a UM2. You're going to add a whole lot of extra work to *properly* mount those bearings without distorting them and adding the proper preload etc. I looked at them a while back to replace the 8mm UU bearings on a Prusa. I wound up just building a new machine (using the old electronics) and OpenBuilds bearings/extrusions. You have some research to do regarding the Igus stuff...Here is one example: http://toms3d.org/2016/06/07/should-you-be-using-igus-polymer-bushings/
