Don't forget that not all and is the same either.by Greg Frost - General
At some point in the evolution, I released this version which is still my favorite. Note the enlarged opening at the top. This give much easier access to the hobb which allows you to see if it has chewed a bit of plastic off which can cause intermittent slippage. With the widened opening, you can just get a needle in and scrape the clogged tooth clear without disassembling anything. Unfortunatelby Greg Frost - General
QuoteHlias Can anyone suggest any possible solutions to the problem? Do you have a pla carriage? It looks to me like you carriage may be softening during long prints resulting in nozzle displacement. The displacement probably depends on how the filament is spooled. It may return to its original position when the printer homes again at the end of the print. If that is your issue, the solution isby Greg Frost - Printing
Did you print those objects separately? It looks like you printed the cube in its own, and it is far to small an object to print on its own without some kind of cooling strategy. The layers below had not set when the next layer was being printed. You need to either slow things down significantly (minimum layer time) or have some kind of active cooling (fan directed at the nozzle output). The ciby Greg Frost - Printing
The menus have been reorganised in the 2014.03 version.by Greg Frost - OpenSCAD
You could bodge something up connecting the enable, step and dir pins for the z motor(s) from RAMPS for example to either 2or4 stepper drivers on some prototyping board. You don't need firmware support because they would all step at the same time. I say 2 or 4 because you could drive 2 motors from a single driver either in parallel or in series as is done by many printers now (mainly prusas and dby Greg Frost - Developers
Some of the openscad designs can produce a bom for you. I thought that this was the case for the Prusa i3 and the Mendel90. When it is done that way, it is much easier to reliably keep the bom up to date with an evolving design.by Greg Frost - General
Quotenophead I think your assessment is fair. Neither Sound or Daid recognize the problem, so I doubt they would even accept patches to fix it. Unfortunately you were quite right about this nophead:by Greg Frost - Slic3r
I ran up an old version to check and youre right, it is under the Advanced tab (which is crazy because really there should be one size per extruder, and it should be associated with the Machine, but on your version I got this: I'm gonna try building Daid's version to see if I can get that working.by Greg Frost - Experimental
hmmm. I got it to run, but then had some problems. The first run wizard went through ok and I entered a custom machine profile with 0.5mm nozzle and selected relative E. Then when it got to the cura interface, Shell thickness was highlighted red. When I click in the field, it says "incorrect nozzle size". I went into the machine settings again and there no longer seems to be a place to enter theby Greg Frost - Experimental
Sublime: If you are going to submit a pull request, you might want to fix a few things up.: I got a compiler warning as a result of one of your changes: gcodeExport.cpp: In member function 'void GCodeExport::writeMove(Point, int, int)': gcodeExport.cpp:228:8: warning: suggest explicit braces to avoid ambiguous 'else' [-Wparentheses] You need to put braces around your new if clause.

are you going to pull request these changes? I have been trying unsuccessfully so far to build it on windows and would love to give the inset change a try.by Greg Frost - Experimental
They are already squared. That is what the pow(...,2) is doing.by Greg Frost - Developers
Sounds like you need to tune your PID If it is behaving that badly. It shouldn't significantly overshoot in this scenario unless something is wrong. I agree that it is a very bad idea to use your bridge flow rate but not your bridge speed. If your printer is tuned for speed, the limiting factor is often the extrusion rate the extruded is capable of. If what you describe is true, you would have toby Greg Frost - Slic3r
Have you built this on windows? If so can you package it so we can try it out without having to get the build environment setup?by Greg Frost - Experimental
Is the end stop for that axis functioning correctly? Are you using Ramps, and if so, have you checked that the pin that connects the addition to the ramps board is making good contact? You should be able to probe the DIR pin on the stepper, the ramps board and he radii no and see where it is failing.by Greg Frost - General
Is that model only for the perimeter or for loops and infill as well? If used for infill, wouldn't that result in paths that don't bond well to adjacent paths?by Greg Frost - Slic3r
+1 vote for the inset value. The simple procedure I used for calibration was to first calibrate the flow by printing solid objects based on when the top surface is properly filled and smooth. I realize that the best way to calibrate flow is just to measure the amount of filament that is pulled into the extruder, but that will not take into account the fact that you can't actually fully fill a reby Greg Frost - Slic3r
QuoteSublime@ Greg Frost I wrote a quick script that lets you reduce the flow rate of the perimeters like you would with skeinforge but works with Cura and Kisslicer if you would like to try it out. . It allows you to adjust any extrusion types flow rate using Marlins M221 flow rate modifier and has Nopheads flow rate equation in it for the perimeters so all you have to do is enter the layer heiby Greg Frost - Slic3r
QuotenopheadI intend to fork Cura and fix it because I like its simplicity and it is written in C++, albeit with a bizarre form where everything is in .h files. I believe that CuraEngine has recently been refactored now so that the code is more conventional (only declarations in the header files). What would be the principal difference in the ground up slicer you would write. What language wouldby Greg Frost - Slic3r
I have been 3d printing for many years now and have been patiently waiting for a slicing solution that handles the implications of rounded extrusion profiles properly but nothing has ever appeared. Skeinforge seems to be the only slicer with enough settings flexability to make it work (by fudging perimeter widths and flow rates) but it is a pain to work out since the fudge factors needed are diffby Greg Frost - Slic3r
The orifice length also plays a big role. If the 0.5 mm hole is too long, it will limit your speed. Too short will wear out quickly and also be prone to more ooze. Striking the right balance can play a big role in print quality.by Greg Frost - Developers
It has been proposed that bountysource be used to manage bounties. It seems to me that they are on an absolute winner. If a bounty is never claimed (perhaps for some reason the bounty is overtaken by events because the terms of the bounty somehow no longer apply) then they just pocket the cash. Am I reading their terms and conditions wrong? I can think of a few things I would sling a few bucks fby Greg Frost - Bounties
I wouldn't bury it in folders. Just a forum directly beneath developers forum called bounties. The only management overhead would be someone stickying a bounty post and unstickying it after it is claimed. Bounty related discussions could also take place in the same forum but those threads would not be stickied.by Greg Frost - General
To keep all the bounties in one place and expire them when done, couldn't we have a forum category and sticky a post with each bounty? The. When the bounty is claimed, just I sticky the post?by Greg Frost - General
Y pulley slip or belt tensionby Greg Frost - Reprappers
what you are seeing is backlash. because those walls are approached from a different direction, the lash in your system leaves a gap between them. I suggest you attempt to adjust your mechanics (tighten belts etc). you are using machined pulleys? if not, do. and if all else fails compensate for lash in your slicing.by Greg Frost - General
This is a very old post that you have responded to. These parts are a very early prusa 1 version. I really think you would be better going with a more up to date set of parts. I certainly don't have the sources anymore for such an old set. You should still be able to follow Gary's instructions with a prusa2 set of parts.by Greg Frost - Plastic RepRap Parts for Sale
