Re: New Botmill Glider 3.0 Experience - 12 years ago

it's hard to convince people.... when your first six posts ever on the forum all happen to be about how great the vendor that has a really, really, really bad reputation is.

Re: Mbot3d machine whats it like? - 12 years ago

for the money why not just buy a real makerbot or build a reprap much cheaper? smells like a cheap chinese clone to me.

Re: Z axis M8 nuts riding up / sometimes no movement on Z axis - 12 years ago

i had the same issue with my aleph objects x-ends until i placed a properly sized spring above the nut. an extra side benefit is that it give you a few mm of upward travel in case you smash the nozzle into the bed. not a replacement for bed springs, though it could be if you were so inclined.

Re: why do you all love ramps? - 12 years ago

it's pretty hard to help when all you've said is basically "it doesn't work on my computer". what operating system? do other arduino's show up (as a com port) in the arduino ide? if you use windows, did you install the arduino mega drivers windows requires? with details come useful answers.

Repetier Host VBO's - 12 years ago

I've switched to Repetier Host software, and it is awesome. The only problem I'm having is that the log says something to the effect of "you can't use VBO's for rendering" when it starts up. This is weird as I have an nvidia quadro workstation card with excellent opengl support. Also, when the print is running the "live print" window goes for a few layers then stops working altogether. Is thi

Re: When Will Makerbot Release the Replicator files? - 12 years ago

i want the .dxf's just so i can build one out of something other than wood. why they chose wood over aluminum is beyond me... if it were AL or anything else i'd have just ordered one. i hate the idea of using a material that expands with humidity to build a precision machine.

Re: New Botmill Glider 3.0 Experience - 12 years ago

Wow lots of <10 posters coming to bat for botmill. Either they turned fantastic overnight and their new happy customers just happened to find this forum, or.... Seems pretty transparent to me. An underhanded. I'll stick with the reputable shops...

Re: Quality of MendelMax vs Ultimaker - 12 years ago

I don't know how people are building MendelMax's for anywhere near $1000. Like i said before mine totaled out just under $750, and that's with lead screws, precision ground smooth rod with bronze bushings, and a custom y-axis with cast aluminum build plate ground flat to a thousandth. My build was originally $568 total before I added the lead screws and better smooth rod (used threaded/drill ro

Re: Quality of MendelMax vs Ultimaker - 12 years ago

I went with a mendelmax based design and ended up spending about $750 total on the build. The prints are very, very nice.

Re: ABS stripping problem - 12 years ago

thanks for the advice! i'll give it a shot. i'm using a j-head mkiv-b and ultimachine pla/abs. it's started giving me problems with pla as well now.

Re: ABS stripping problem - 12 years ago

i'm using slic3r. the temperature seems to be consistent. it doesn't seem to affect anything. it's only ABS that gives me stripping problems. PLA only does it when i set the z-home too low

ABS stripping problem - 12 years ago

everything was great with my mendelmax until about a week ago. i had to replace the filament as it had ran out. i had done this many times before with no issues. ever since that time, the extruder simply will not extrude abs. it always strips the filament. on my wade's extruder, i've tried to tighten the springs all the way down, loosen them up, higher temperature (250ish) lower temperature

Re: Sprinter or Marlin with Mendel Sangu 1.3a - 12 years ago

i switched very early from sprinter/skeinforge to marlin/slic3r and went from laying pools of spaghetti to useful prints with virtually no other change. i attribute most of that to slic3r's less insane configuration settings. the most noticeable difference when comparing the quality of equal parts between sprinter and marlin seems to be on the curves. sprinter will pause a bunch going around

Re: Just discovered this 2 weeks ago!!!! - 12 years ago

i will also recommend mendelmax (www.mendelmax.com). no "kits" are available (yet), though there is a complete BOM and plastic parts can be bought from a couple vendors (lulzbot and techpaladin... the techpaladin kit being the better option imho). the good thing about the mendelmax is that there is no adjustment necessary. no lining up of rods. and it's not made of a bunch of wiggly threaded

Re: Nearly There! - 12 years ago

you will set the print temperature in slic3r or skeinforge, then you can change it through the interface realtime as the print progresses. the slic3r/skeinforge setting just sets the temperature initially, after that you can change with the interface. i am not familiar with replicatorg, but i know this is how it works with pronterface. i had a similar issue on marlin firmware when i first se

Re: hotends.com review - 12 years ago

i recently ordered a J-Head MKIV-B for 3mm filament from him as well. Excellent product, fast shipping, couldn't ask for anything more. I'd recommend it to anyone. The J-Head is by far the best performing hot end I've seen (in person) as well. The site says you can't extrude PLA without a fan however I've had no problems at all with it. It oozes a bit, but not enough to cause any problems.

Re: My first reprap is complete! MendelMax... - 12 years ago

i was thinking carbon fiber plate would make an excellent heat isolation material. i have a ducati with carbon pipes and i can hold my bare hand on them after running for hours and they're barely warm to the touch. that is, of course, carbon sheet laid around a mold and impregnated, but i wouldn't think a 3-4mm plate of the same material would be much different. they also make a honeycomb stru

Re: My first reprap is complete! MendelMax... - 12 years ago

i got the plastic parts kit from lulzbot. i am using that long enough to print my own x and y-axis, which will use 20mm t-slot for the y and 10mm (if i can find it, it not then 20mm) t-slot for the x (turned 45 degrees with eccentric-mounted v-groove bearings mounted to a printable carriage plate that engages the edges of the t-slot track). i will also ditch the threaded z-rods for real acme le

Re: Is Anyone doing research into dual head RepRap? - 12 years ago

i did a lot of research on possibly using a second extruder for support material on my mendelmax, though it doesn't seem like the software chain is up to the task just yet. how is makerbot doing it with the replicator? what is their process like in terms of the software side of things? they use replicatorg, no?

Re: My first reprap is complete! MendelMax... - 12 years ago

Thank you very much! It's been a great experience all around. Next up is a milling head and a laser attachment for PCB etching. This is exciting stuff! I thank all of you for all of the work you've done to pave the way for johnny-come-latelys like myself. I do have one question to solve a nagging issue, though. It seems as though (after calibration) all of the prints are coming out very n

My first reprap is complete! MendelMax... - 12 years ago

Hello! First post here. I just finished my first ever reprap project, a MendelMax with RAMPS 1.4. It took probably a month or two worth of intermittent work to complete, and went together VERY easily. I'm using Marlin for the firmware and the calibration was likewise very simple. I expected far more difficulty getting everything lined up and calibrated. I've included a youtube video of my f
