FabLab opens in Limerick... - 10 years ago

Hi all Irish RepRappers! Of general interest to makers and 3D printer groups and individuals, a FabLab has opened in Limerick: More detail here: Also, there's a Makers Meetup on Thrusday 24th Apr 2014, 7:30pm [ 7 Rutland Street, Limerick], and a Build your own 3D printer workshop weekend on the 26th/27th Apr (limited places). I'm giving a short talk on the accessibility of 3D printing, brin

Re: How would you slice this stl? - 10 years ago

Hi Nilez, Send me on the file and any other variables you'd like me to consider in test printing, fill density, layer height, etc. I'll run a few tests and return some picts to you. Not a problem. "All in the aid of science", or 3d printing, as the case may be! :-) NumberSix

Re: How would you slice this stl? - 10 years ago

Hi Nilez, That looks more like vibrational ripples than Sketchup stepped curves. I use Sketchup all the time for drawing objects I print and when I haven't put enough steps in a radius/circle it will show as straight facets in the print. You know you can smooth a Sketchup Arc/Circle by typing xxxs just after drawing it, where xxx is the number of steps in the curve. The greater the number the smo

Re: Optional cooling fan - 10 years ago

Hi Muelli, If you are planning to controll the large "end of print cooling fan" from the end.gcode then the "G4: Dwell" command will be of value also. You will want the fan to stay on for 6 minutes or so, then switch off. I use a different controller board on my Mendel90, but the end.gcode will be similar bar the Pin ref. I read somewhere that it works better to bread the Dwell into smaller time

Re: 4 PLA Bushings (Mendel i2) - 10 years ago

Hi James, How many linear bearings are in the bag in Pict 3? It will be best to use the linear bearings (photo 3) under the y-carriage and in the x-carriages, if you have to make a choice between linear bearings and PLA bushings. If you have enough linear bearings user them in the X-ends also (two each side typically). If you don't have enough use the pla bearings (Linear bearings substitutes) i

Re: Beware of the Fan Control in Skeinforge Cool plugin - 10 years ago

Hi Neil, Thanks for the additional info. I now have the cool.py with fan related settings. I've played with it a bit, as I'm interested in cooling with varying fan speeds. It looks like it's behaviour is such that if "Turn Fan On at Beginning" is selected then an M106 S255 is inserted near the start, and no further M106 commands are used (presuming you have Max set to 255 as you suggest). If this

Re: Beware of the Fan Control in Skeinforge Cool plugin - 10 years ago

Hi Neil, Can you clarify something for me so I can understand this issue a bit better. Is there "advanced fan control" within Skeinforge or was it just that Skeinforge Cool was trying to turn the cooling fan on but the fan speed was set much lower than Max 255, perhaps in firmware? I thought my Skeinforge was up-to-date but I don't see any settings that might vary fan speed within "Cool". ------

Re: Beware of the Fan Control in Skeinforge Cool plugin - 10 years ago

Hi guys, If the 12v circuit to the work cooling fan is a pulsed supply, (Nophead may clarify this in relation to the Melzi board supplied with the kit), then I think accurate speed control of the cooling fan on the Melzi may be obtained by the simple addition of a diode and capacitor (basic soldering knowledge assumed). I encountered the same scenario you describe above when using Slic3r cooling

Re: New X-Motor/Idler designs. - 10 years ago

The manual got updated too, to reflect changes and a few new photos also! I'm sure Chris will be along with comments when he gets a chance, but it does look like the brass nut (z nut) now is just trapped between the side walls at the top of the channel. I notice the j-head hotend ships with a sleeve wrapping, and the cooling fan ducting has a little hole to keep the ducting that sits around the

Re: My direct drive extruder mount (EZStruder) for the Mendel90 - 10 years ago

@Goopplastic I noticed your mods of the opening and hole mount hole/spacing on closer scrutiny of your x-carriage (file you posted to thingiverse). The idea is still neat, and I can graft it to the stock x-carriage. Tks. Hadn't looked closely at that "EZStruder" before. That thing is like the milti-tool of extruders! Oh... those stlye bearing mounts are notorious for cracking if printed in PL

Re: My direct drive extruder mount (EZStruder) for the Mendel90 - 10 years ago

Hi there, That's an excellent modification to the x-carriage. It tucks the 40mm fan in very neatly under the carriage. I was working on a clip-on attachment design to attach a fan but it just might be easier to reprint your carriage design! Thanks for sharing. I think active cooling of the j-head insulator (peek) is a very good idea. the addition of the shroud should direct the air nicely. Che

Re: Azteeg X3 and external Mosfet connect-up Question... - 10 years ago

Hi Roy, Thanks for the prompt response. I do have the cover as in the pict above, so I'll try my fan in the H-END3 (D16) connector as you suggest. One final question... In Marlin do I simply change the "-1" to "16" in the " #define HEATER_2_PIN -1 " line, in Pins.h tab (MOTHERBOARD == 34 section)? What g-code command will switch on the fan? I presume M42 P16 S255? Thanks again! Ivor

Re: Azteeg X3 Controller Pre-Order. Limited time pricing. - 10 years ago

Hi Roy or any other Azteeg X3 user, Could you take a look at a technical question I've posted regarding how to connect an external mosfet to the X3, in order to drive a larger fan? The question is posted in the Electronics section --> Here. Any guidance or clarification that could be provided would be appreciated. Regards and thanks, NumberSix

Azteeg X3 and external Mosfet connect-up Question... - 10 years ago

Hi folks, The Azteeg X3 has what I read are "lower power switched mosfet outputs", four of them, marked D4, D5, D6 & D11 (length ways) and 12v, sw, 5v (inwards), on the board. See photo curtsey of Panucatt.com (the red arrow is mine ) Wiring Diagram here. I have already connected two low powered 12v fans utilising D4 and D5 positions, by connecting the fan (-) wire to the SW Pin (middle pi

Re: Nophead\Marlin vs main Marlin... - 10 years ago

Quick update. Above Marlin downloaded to Azteeg X3 board and desired feature (Automatic operation of extruder insulator cooling fan based on hot-end nozzle temperature) tested and functions nicely. Chris' (Nophead's) changes are also present and functioning, but I had to explicitly state the Z_MAX_POS line (e.g. 203) to overcome the "'Z_MAX_POS' was not declared in this scope" error that was pre

Hi QuackingPlums, I can confirm that changing "define Z_MAX_POS (Z_HOME_POS - 0.1)" with "define Z_MAX_POS (203.0 - 0.1)" has allowed Verification/Compiling to complete successfully. Thanks, Ivor

Re: Nophead\Marlin vs main Marlin... - 10 years ago

Neil, Good tip about the "diff" tool. I tried out "ExamDiff" and compared some files from both Marlin versions, but I think as you probably suspected it would be a tedious job to get one good consolidation. Gerv has the merging done for me in the version of Marlin he maintains it seems. Chris, I hear what you are saying about Marlin, lots of complication and growing pains. Thanks for your input.

Nophead\Marlin vs main Marlin... - 10 years ago

Hi all, I like the way Nophead\Marlin has the HOME_POS and other settings tuned to the Mendel 90 design. But, there is a new feature in the main release of Marlin that I also very much like and want to try out. It's the "Automatic operation of extruder/cold-end cooling fans based on nozzle temperature" feature. I think feature will work with my Azteeg X3 board which I have on my Mendel 90. I cu

Re: x idler bracket clamp splitting - 10 years ago

Hi Chris, The bar clamps on the x-ends has been a weakness in many x-end designs. One of my clamps cracked also despite being so careful while tightening (my own printing). Your indication of a change to a clamp style design, where I presume the clamping tab is printed so it's layers are in compression instead of shear, will be a good improvement. I think the benefit may out weigh the additional

Mendel90 extruder wiring connector variant offering...(functional mock-up) - 11 years ago

Hi all, (first post to this section!) First and foremost I must thank Chris (Nophead) for sharing his fantastic design, documentation and stl files. The consideration that has gone into every aspect of his printers design is very evident, as I've recently printed and assembled the sub-components, and closely studied the documentation, and his many many posted answers to questions. Thank you Chri

Re: Making a Prusa Mendel look "nicer"? - 11 years ago

Hi Tuficneme, You could put a box around the Prusa Mendel, but I think it would just look like a Mendel in a box, to anyone that knows the printer. It may clean up the look for others though. The box shape on the other printers is part of their design and part of their look. To me the Mendel wedge shape has become the recognisable shape of a "RepRap" printer, a sort of Classic. You can certainly

Re: changing the size of an object - 11 years ago

Since you've mentioned Repetier-Host, you can also scale directly in the 3d view. Another handy feature I use with long narrow objects is the Rotate around Z axis. It allows you to fit longer objects diagonally on the bed, squeezing every last mm out of the space!

Re: A Bust Philosopher - 11 years ago

Hi there, That's printing very nicely! Lovely finish. What are you slicing with? Kissicer? It looks like the support broke away very nicely. Did you have to do any clean-up after the support was removed? ABS or PLA? How's the pumped air cooling working out? Looks like it can be a nice focused way of delivering cooling. Good work.

Hi Kouu_Tori, Interesting... most people dig into how it works then get a printer. You're the first person I've seen to acquire a printer and then ask "how do I control this thing!" I use Repetier Host with my Prusa, but I don't have RAMPS. I find Repetier Host good. Welcome to the RepRap forum. You're in the right place if you have any more questions. Happy printing!
