Thanks. I actually found there is a mirror function in openscad, so that is working perfectly for me.by AVRkire - General
Any way to mirror a print? - 13 years ago
I am trying to mirror a print. I am using slic3r or KSSlicer, and either repetier or pronterface. I don't see any way to mirror in any of those. My design is in openscad, so if there is even a way to do it there it would be great too. Thanks!by AVRkire - General
Servos instead of steppers? - 13 years ago
Has anyone ever built a printer using servos instead of steppers ? I'm wondering why steppers are the norm over servos. I would think good quality servos with positioning capability would have some advantages over steppers, but I don't really know enough about steppers to understand their advantages over servos.by AVRkire - General
Re: Screw / nut blanks for threading with tap + die - 13 years ago
I print parts often that need to be tapped. I print the hole to be tapped slightly smaller than the desired final tapped hole. It works pretty well, but the threads cannot handle a lot at all, they are pretty brittle. I do it more for prototyping than actual parts.by AVRkire - General
mid print filament change? - 13 years ago
I have been running a print for about 6 hours, and I have 2 hours left. I believe I will run out of filament on my current roll in about 1 hour. Is there anyway to put in a new roll of filament mid print? I have the same color, from the same source so it should be exactly the same, just not sure how to do it without ruining my print, and I really don't want to lose 7 hours worth of printing.by AVRkire - General
Re: 2 color prints - 13 years ago
I don't think that STL files can have multiple colors. I remember reading that someone was coming up with a new type of STL file that could have colors. Even if you did, that would only be have the challenge, the slicer program would have to be able to take those multiple colors and translate it to the exturder in the gCodeby AVRkire - General
DLP printers - 13 years ago
I have seen a few videos of 3d DLP printers, and the results look really nice. I did some searching, but I cannot find much info on how these actually work. I know they are curing resin, but I don't understand much else. Does anyone know of any sites or places where I can learn more about the technology and how it works? I am very curious to know how realistic it is to build one.by AVRkire - General

Re: layer separation on taller prints - 13 years ago
Nophead. If I understand banding correctly, that would be caused by using an incorrect layer height based on the Z axis threaded rod. My layer height is set to 0.2 in the pics above, and I am using a 8mm normal pitch threaded rod, so I was under the impression that I can use any multpile of .1 for my layer heights? I ran another one yesterday, at 0.3 layer height, and at a much slower print spby AVRkire - Printing
Re: layer separation on taller prints - 13 years ago
I actually tired that, and unfortunately when I did that my filament ended up slipping in the hobbed bolt and the filament stopped feeding and print failed. I will try this again, thanks for the feedback.by AVRkire - Printing
Re: layer separation on taller prints - 13 years ago
I kind of figured that. I was hoping slower speed or something like that may help, but it does not seem to. I think a enclosure is going to be really tough on my mendelmax. I may see if I can give heat lamps a shot. Are there any pictures of heat lamps being implemented that anyone knows of?by AVRkire - Printing
layer separation on taller prints - 13 years ago
I am noticing that every time I print something taller, say above 30 or 40mm, I am getting layer separation. I am printing with ABS, heated bed at 110. I never have the problem on shorter prints, even if they are wide. Here are some pics. Anyone have any ideas of what I can do to fix this?by AVRkire - Printing

4 steppers for one axis? - 13 years ago
I am not sure if this is an electronics or mechanics question. Is it possible to use 4 steppers for one axis (z)? I would have to splice 2 and 2 to use with Ramps given only 2 z inputs, but would this work? Any downsides? My reasoning for wanting to do this is for balance rather than for torque/power. I am finding that with a larger bed, no matter what I do I cannot seem to get it balancingby AVRkire - Mechanics
Re: The Disappointments and Failures of TrinityLabs Aluminatus - 13 years ago
This is interesting. I actually have bought a few things from them, some have been great, some have flat out sucked. I was really intrigued by the aluminatus, and strongly considered buying one. At the end of the day I just thought it was too much money, and was nervous by the few things I bought from them that sucked. I am sorry to hear some people are unhappy with them, these are very expensby AVRkire - General

Re: 5 and 11 amp ? - 13 years ago
Well, I tried connecting the 11amp inputs as well. Same thing, a light buzz on the motors, but no turn, even with no torque at all. Any ideas?by AVRkire - RAMPS Electronics
5 and 11 amp ? - 13 years ago
I'm building a new printer and I really want to test out just my z axis, as that is the only thing ready. I'm going to use 2 PSUs, a 24 v for the bed heater, and 12v for the rest. I don't have my 24v heater yet, so I only hooked up my 5amp input connections to Ramps. My understanding was that the 11 amp input was only used for the heaters. I've uploaded Marlin, and connected everything to Proby AVRkire - RAMPS Electronics

Trying to test new z axis - 13 years ago
Hey everyone, I am working on a new printer, and all I have so far is my z axis, no extruder, no therms, nothing. I have hooked up my PSU, hooked up my RAMPS 1.4, flashed Marlin on my Ramps as was on my current printer, except I tweaked the Z steps accordingly. I connected to both repeater, and also pronterface, but when I try to move my z axis up or down I get the following error: < 3:53:by AVRkire - Firmware - mainstream and related support

Y inverted setting - 13 years ago
Hey everyone, been printing for a few months now, and my latest print showed that my y is inverted, or my x is depending on how you look at it. I went into Marlin firmware that I have installed and saw two possibilities: #define INVERT_X_DIR true // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false OR #define X_HOMEby AVRkire - Firmware - mainstream and related support

Re: At a loss - 13 years ago
Sublime, Thanks for your help. I tried switching over to KSS and it seems to be much, much better. I am not quite sure why, I probably have a setting or something off, but I am not getting the extra extrusion in KSS. I kind of like it a bit better than slic3r as well. Thanks again for working with me on this, much appreciated.by AVRkire - Printing
Re: At a loss - 13 years ago
Komb, yes, I have verified my filament width several times, it's very consistent at 2.91-2.92 Sublime, thanks, but I'm being dense and do not quite follow you when you say set perimeters to 1. Is that 1mm or 100%? Thanks!by AVRkire - Printing
Re: At a loss - 13 years ago
So I checked my z axis, it's still right on the money, 1 sheet of paper off the bed everywhere. I ran a single wall calibration test. The STL says 0.5mm, however the gcode from slic3r is showing: perimeters extrusion width = 0.37mm ; infill extrusion width = 0.37mm ; solid infill extrusion width = 0.37mm ; top infill extrusion width = 0.37mm ; support material extrusion width = 0.37mm ; firstby AVRkire - Printing

Re: At a loss - 13 years ago
So now I am REALLY confused. This am I decided to try a few prints, using slic3r again, same settings I have been using successfully PRIOR to trying the big print. These were much smaller prints, that I have printed very successfully. THey all had way too much plastic extruded, much like the big print that started this thread, so it was not related to the size of the thread. I double checkedby AVRkire - Printing
