  1. Thanks for clarifying JDRM, I just didn't realize the cartridge was the same size and shape since my old one failed and needed to be replaced anyway. I got a new PT100 and the E3D is working great now. It's nice to see somewhat of a standard in those shapes.
  2. I'm running into this same thing, except, I'm wondering if I can use the e3d therm on the UM2 mobo? Sounds like it's not possible without some adapter due to the way the electronics are designed.
  3. I recently had someone interested in this so I posted what I've been using to get Gcode from Maya on GitHub. It's nothing fancy right now but it's just an obj export and launch Cura application with a Python script on the shelf. I didn't get too far with my previous approach, and Cura seemed to be changing too rapidly to keep up. Maybe now is a better time to get back into it with the new Cura 3.x https://github.com/Brictone/MayaToGcode
  4. I have the cooling per layer set to 17seconds, with a minimum speed to 10mm/sec. I'm testing 5mm/sec now. Since yesterday I pulled the Z rod out of the older machine, cleaned it and re-greased it. It's actually more stiff than it was. Before the bed would fall, when the motor is disengaged, under it's own weight to the bottom now it barely falls if at all. I also loosened and tightened the Y Axis pulley set screws. I am thinking less and less this has to do with X Y and Z mechanical alignments or calibration. But I'm happy to revisit everything and anything if anyone has sugg
  5. Well I went and pulled the Z rod out of the newer machine, I suspected it was worse since layers were inconsistent. It always skips or gets stuck on a layer about 1cm high. Regardless these consistent layer differences are still in the test piece. So it did not improve the problem I was having. I also added tensioners to the Large Y Axis belts. Just to clarify, I am getting different outside layers depending on whether or not the layer is solid or is hollow with 20% infill. They just look different enough on X Y axis. Solid layers are not as large in the X And Y axis.
  6. Very interesting thought on the Z axis. I'll give the Z rods some attention. I just had a thought of increasing the tesselation of the model, right now it's very low poly, to see if it makes a difference. My thought is if the Z rod was dirty I would expect inconsistent results, right now it's perfectly reproduceable. Even if I lengthen the model on the Z. I used to have some belt tensioners, I used clothes pins springs. I can try that again. Although if the belts were loose I would expect see ringing and vibrations in the print. Which I do not.
  7. Hi All, I've had my printer for over 7yrs and have torn it down and replaced parts and re-built it more than once. In face I have an UMO+ I purchased a couple of years ago and both have the same issue. They both have the UM2 electronics. So they are very close to the same. I'm getting these odd layer sizes with features of a print. I've done everything I can think of. I tightened all 12 pulley set screws, re-seated the XY motors, tightened belts on one. changed filament. The problem exists on both printers so I don't think it's mechanical. He
  8. @Daid, I actually just tried the model with the new beta and it did slice at .04mm, so yeah you really did fix the bug. I even tested it at .02mm, it used more memory but still sliced. Then the final nail in the coffen I tested it at .01mm and it failed when the memory usage hit 3.4gb or so. This is obviously not my goal printing at .01mm but just pushing the limits on this 1.5million poly for you. One other thing, Not sure if it's possible but thought it would be a nice feature. Would it be possible to either implement a delay after changing a setting, like Scale or rotate layer height
  9. I think this has come up before but is it possible to compile cura for 64bit windows? I've been printing more and more highpoly models, 1million+ and the slicing quits when the curaEngine.exe hits about 4gb of RAM. I can scale the model down or use larger layer heights or reduce the poly count but all of which reduces the quality I'm going for. Is there a step by step on compiling it for 64bit? or does this require some significant code revamp?
  10. Anon4321 I updated the firmware appropriately and everything is working the way it should. I was just wondering what the difference was. Amedee thanks for that. I'll keep that bible in mind for more info like that. This was more of a curious question than a concern. Everything is working great so far. even with my blown capacitor :(
  11. Hey All, I got my kit and got it installed last weekend. Everything is working good. I just had a couple of questions. Steps per millimeter for the new lead screw must be different. Based on the old lead screw there was a thread floating around that the minimum distance was .001875mm So I was going to print with layers according to a multiple of that number but any idea what the new number might be? Is this still the same? I can't put them next to each other as the printer is running but it seems like there more threads per/cm or inch or whatever. Also I'm clumsy and broke a tiny surf
  12. Thanks for the tip on the little blue vertical line on the path preview in Cura. I didn't know about that. I've already moved on to another model I need to print but I'll keep an eye out for that.
  13. I must not understand how a travel speed can run at 175mm/s if the steps are limited to 48mm/s in the firmware on any one axis. Is this just for the extruder? Does the M203 E4000 override that? is the 40,000 step limitation a different scale than the E4000? I walked away while it was in the upper section. sorry I just don't know if it was failing to retract at all. Infill speed 40mm/s Inner shell speed 30mm/s Outer shell speed 25mm/s Minimal layer time 7.5 Layer height 0.05mm I think I see what was happening. Since I made a small part to test it may not have met these minim
  14. Alright so I made some small progress. very small. Here's what I changed. M203 E4000 in the start Gcode Retraction speed: 50 (I haven't noticed skipping or grinding but that thing whips back and forth pretty quick.) Temperature: 210 I have a shim that came with the v2 extruder drive kit. The whole thing still seems to move a bit. I did mess with a retraction distance of 5.5 and it seemed worse. Other notes about my printer: I have purchased in the past the Knurled drive bolt v3, extruder drive upgrade, hot end upgrade v2 (which came with a little blue shim) Firmware 13.12
  15. Awesome, I'll be going through this list of advice and see what works best for me. Thanks!
  16. I'm trying to use retraction and I can not seem to prevent strings from happening. I haven't been able to find concrete Cura settings for the Ultimaker 1. This is what my settings are at. layer height: 0.05 - 0.1 travel speed: 175-200 speed: 30-40 Temp: 220-225 retraction speed: 40 retraction distance: 4.5 I noticed the strings are less durable with retraction than without making it easier to clean up. I assumed they would be non-existent with retraction if it works. Any advice? Are there better settings than what the defaults are set at in Cura?
  17. It should work with just about any version of Maya although I haven't tested it on anything else. Updating is still worth it but it shouldn't hold you back from trying the script. and putting it in the scripts in the non-version scripts folder will make it available to all versions that are installed.
  18. I updated the script on my site and you can find it here. http://www.bg3d.com/archives/1101
  19. I was using maya to position the model on the platform but I think Cura has made that easy as well by just sticking it on the platform at the origin. I was also using Maya to merge and mold multiple geometry together to make a water tight STL. Cura now makes it a easy and slices multiple objects together without creating cavities. There's some options with that too. So, I've changed the script significantly in order to accommodate all the updates that Cura goes though. So what I've done is taken the selected geometry or group of polygons and export them as an STL with the name of the sele
  20. I'm having problems with this too except my printer is so old I don't have a spare cable or connector. Anyone know the part numbers so I can order some new ones on digikey?
  21. Daid, Thanks for the update on the 19.5v. I'll go ahead and use it. I can get back to manufacturing my mario mushrooms tonight!
  22. Thanks for all the info. I left the adapter unplugged from the wall all night and tested it again this morning and I was getting some voltage from it. except it was bouncing between 15 and 19 volts. I plugged it into the printer again and it flickered for a second. so I tried the new one at 19.5v and it powered right up. As gr5 mentioned, it'll heat up the electronics more than the original, so I'm not going to use that one. I'm going to find an exact match with Volts and Amps. I'm not interested in buy new electronics if I don't need to. Thanks all.
  23. I've had my Ultimaker for a good while now and it's been pretty good to me except last night I found it powered off part way through a print. :( I tested the DC end of the adapter and I get no voltage from it. So I went to the store and found the closest thing to it. a 19.5v 6.14a adapter. Before I plug it into the machine I want to know if I'm going to hurt the electronics at all by using this new adapter. It's the same pin size so it'll fit... just slightly different voltage. Will it decrease the life at all over time? run hotter? should I just return this new one and go and get the sam
  24. I reinstalled, same problem. It seams weird that my previous install of cura 12.12A that was working, is not now. When I run it without a profile (INI file) it makes it most of the way and crashes on something, I can't remember the exact part of the slicing. I can look that tonight up if it would help. Works great on 12.11 still, I'll just use that in the mean time I guess. I hope I'm not missing out on any slicing enhancements.
  25. ok, I tried to get the command line to work this time. I did with 12.12 again... sorta with errors. Here's what I did. I tried exactly what you said Navigated to the software\Cura folder "C:\Software\Cura\pypy\pypy.exe" -m Cura.cura -p "C:\Queue\Cura.ini" -s "C:\Queue\Pyramid2x10.stl This is the error I got: Traceback (most recent call last): File "app_main.py", line 51, in run_toplevel File "C:\Software\Cura\pypy\lib-python\2.7\runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "C:\Software\Cura\pypy\lib-python\2.7\runpy.py", l
