Now that we are on the subject of solvents, I just wanted to chime in to warn about the dangers of messing around with DMSO. It has the ability of bringing anything dissolved in it through gloves or skin right into your body. I work in a chemistry lab and this is one solvent that we try to avoid using and when we do, we treat it with an enormous amount of respect. Anyway, I don't wait to rain oby ambiguousphoton - General

What would you charge for a TK-0 set of printed parts?by ambiguousphoton - Plastic RepRap Parts for Sale
I hadn't considered plastic bushings and aluminum shafts. How do they move compared to lm8uu? banthafodder- which rods did you buy in particular from mcmaster? Were they ground stainless smooth rods because I saw that they ran about $30 for 500mm, or something cheaper? akhlut- where did you get those trapezoidal leads screws and are they just cheaper or do they work better? What material did yoby ambiguousphoton - General
Hi Everyone, I was wondering what the current best advice was for buying smooth rods and z lead screws. I am looking at putting together a TK-0, so I am looking to spend in the $800 regime and they suggest stainless steel for both but I wasn't sure if it was necessary. For the smooth rods they suggest SSFHR10-500.0 by Mitsumi which are these polished 10mm diameter by 500mm 304 stainless steel wby ambiguousphoton - General
Hey Enlightx, Could you comment on the stability of the single plate i3? I am curious how it compares to a prusa v1/2 or a mendel max. Thanks!by ambiguousphoton - General
This printer looks absolutely amazing thank you so much for paying such attention to the details. When are you planning to sell partial or full kits? I have a rumba board already but this looks great!by ambiguousphoton - General
Thank you for bringing up the reprap pro tri color. I was looking at that machine and I like the tri color part but I notice that it is essentially unchanged from the prusa mendel as far as the construction. Does the two bottom braces that they added firm up the frame enough that it would be on par with a mendel max or does the fact that they use the prusa mendel indicate that it is firm enough tby ambiguousphoton - General
That's a good point about the supply chain issues. I see that reprapdiscount sells a kit but it wasn't really clear to me where she was getting the makerslide in the first place because even the official website was sold out. Thanks for the automation store link, they seem to be even cheaper than reprapdiscount. Does anyone have any experience with purchasing from them? There seems to be moreby ambiguousphoton - General
Hi Everyone, I am thinking about building my second printer after building a prusa v1 and I was trying to decide what to go with. I want something with the possibility of adding a second or third extruder and just to tinker around with it in general. I also want something that can produce very high resolution prints with minimal wobble, etc. I was looking at a mendel90 or prusa i3 because I thougby ambiguousphoton - General
Hi Everyone, I am trying to better understand the new rumba board and I had a few questions: It says that it can take 12-35V and can drive electronics at that same voltage. If I had some 12 V stepper drivers and wanted to drive a heated bed at 24 V, would that work or how exactly do you set what the voltage is for a particular thing? Can you just drive the steppers, hotend and heated bed at 24by ambiguousphoton - Controllers
Hey Misan, I was looking on github for your fork but I don't see it, where am I looking for that extruder? Thanks!by ambiguousphoton - General Mendel Topics
I think I have it! The newest version of slic3r is strange in how it lays out its configuration files. Apparently there are separate files for different parts of the printing so even though I had my settings loaded in for the filament section, it was using default sections for the print settings section. Reverting back to and older version of slic3r fixed this. The whole new layout doesn't realby ambiguousphoton - RAMPS Electronics

I am having some issues with my calibration on a prusa mendel with ramps 1.4, marlin 1.0 software. When I check the Z axis and tell it to raise 10 mm in pronterface, it does exactly but when I print a calibration it measures either 6mm or 8mm in height instead of 10. I am also running into issues where everything is quite squashed. My layer height is 0.4 mm on a 0.5 mm nozzle. Has anyone run inby ambiguousphoton - RAMPS Electronics

I have built a few prusa mendel kits from here: They seem to do a good job. I do like the look of the reprap pro though but I haven't seen it in action. Since the reprap pro kits are from the guy who invented reprap, I would tend to trust them more but it would be worth asking on the forums and on irc first. You could also check out the mendel90.

Hi everyone, I want to build a prusa i3 with a single aluminum plate but I am confused with the extruder design. The compact extruder does not have an idler and it doesn't seem obvious to me how you would even mount one. There is only two screw holes for example instead of 4. I came across this nice design: I am curious if anyone knows where I can find the plans to that and if there is a singlby ambiguousphoton - General Mendel Topics
Hey everyone,I built a version 2 prusa mendel that is pretty decked out with lm8uu bearings, makergear nozzle, a heated base, ramps 1.4 electronics, and cooling fans. I have printed 4 prusa mendel sets with this as well as a lot of other things so it is a very well calibrated machine (>200 hours of printing), but I am moving and would prefer to just set up a smaller printer at my next place.

Hey there, This is a cool design! What temperature does ptfe get soft at? I see it melts at 327 C but if it gets softer earlier you might be in trouble right? Have you considered a water cooled setup that appeared on the reprap blog post recently? Maybe that could alleviate issues and you'd still have a minimalist design.

Thanks for the Voroni tower pictures Rich and Sublime. Those are some gorgeous prints you have there. I should try printing one, it seems like a badge of honor among rep rappers!

Hey Everyone, For future reference, Makergear gives you popsicle sticks that I thought were for stirring the epoxy but they also work great for holding the extruder in place. You just cut them in half and use each half on either side of the hot end. When you screw down your extruder the popsicle sticks are then trapped between the X carriage and the extruder and will also keep the hot end in placby ambiguousphoton - Plastic Extruder Working Group
