Re: M109 (set temp and wait) in G-Code but not in config - 4 years ago

The annoyance is the hidden behavior. If I fail to put something in the start gcode, then Slic3r will put something in there for me without explanation. Perhaps had there been a comment like "because the original gcode lacked M104 etc we have inserted the following 4 lines for you; if you wish to avoid this in the future, provide your own M104 etc" I would neither have been annoyed nor had to

Re: M109 (set temp and wait) in G-Code but not in config - 5 years ago

Quoteobewan If the slic3r 'start' gcode (1st image above)does not contain any entries for M104,M140,M109,M190 then slic3r (or cura) will add them to the start of your slice'd g-code automatically. This is very helpful information, although this "feature" is a bit annoying. Thank you

As I stated originally, there is no hint of what I find in the G-Code. Please see attached screen shots.

M109 (set temp and wait) in G-Code but not in config - 5 years ago

I've been using Repetier Host and Slic3r for perhaps 5 years. For one set of configurations, the printer waits at the start of a print for the extruder temperature to be reached. This is no big deal except that I cannot find the M109 anywhere in the Slic3r configuration settings. It is not in Printer Settings, Custom G-Code, nor in Filament Settings, Custom G-Code. Is there somewhere else tha

Re: Printy Update: An Open Source DIY 3D SLA Printer - 7 years ago

Projects like this are always exciting and encouraging! I have a LittleRP, which I love, but I often need to print larger objects. 100 x 100 x 100 is an improvement, but I am sure that I will want more eventually. Increasing the Z height (as an option) would be a great idea: in a pinch, I can put the largest dimension in the Z and give it a try. I am seeing more SLA printers which can print

Support generation never terminates in 1.2.9 - 8 years ago

I tried to slice the following STL file, with support. I gave it 15 minutes, but the "creating support" phase never terminated, and the progress bar (in Repetier Host) did not budge during that time Is this a known problem? Any work-arounds? Thanks! Jon

Re: Strings inside of objects - 8 years ago

Turns out that the original responses were pretty much right on. This is one of a family of 3D objects, and this particular object had a location where a bevel was "too horizontal". Once I adjusted the design so that the bevel was more vertical, it started to print properly. Thank you for all of your help!

Re: Strings inside of objects - 8 years ago

Thank you for all of your thoughts, but I have printed literally hundreds of these type of objects without a problem, until the past few months. My printer has been able to print this shape in the past, without support. I wish I knew what had changed.

Re: Strings inside of objects - 8 years ago

Thanks for the help. I can bridge about 1.5 inches with this printer, so bridging should not be so ugly. And this area was designed to be empty, so it is not bridging.

Strings inside of objects - 8 years ago

Recently we have been encountering "strings" on the inside of hollow objects (think of a hollow cylinder). The strings appear in the same locations for each print, and are quite thick (not just wispy hairs) (see photo). So far as I know, things have been stable (printer, filament, etc), but something has changed. I increased the retraction from 1.1 to 2.2 but could see no improvement. Any hin

Re: cannot generate support - 10 years ago

Just crickets, eh? Is this a known bug? Are people working on it?

cannot generate support - 10 years ago

I tried to generate support for this: While some support appears to be generated under the foot, there is no support under the bulk of the object, which makes it unprintable. Can anyone suggest support settings that will generate correct support for the first 80 layers or so? Using 1.0.0RC2 (came with Repetier Host) Thanks! Jon

Re: cannot slice this file - 10 years ago

I had to change Perimeters from 1 to 2. Strange that this caused such a serious bug, with no error message from Slic3r.

by jon_bondy - Slic3r

Re: cannot slice this file - 10 years ago

Your slicing parmeters work here, so there must be something problematic with the slicing parameters that I was using. Still, Slic3r should have reported an error rather than just terminating.

Re: cannot slice this file - 10 years ago

Perhaps if you posted your settings, I could try to see how they differ from mine

Re: cannot slice this file - 10 years ago

Wish I knew a work-around. Like which slicing parameter is causing the problem, or which aspect of the model is causing the problem.

Re: cannot slice this file - 10 years ago

The object, after scaling, is not bigger than the build plate. I sliced and printed a variation on this a few hours ago. This variation will not slice. Slice3r gives up without a whimper.

Re: cannot slice this file - 10 years ago

Thanks for your help... I design most of my parts as 10x or 100x (in mm) and then scale when I load the STL in Repetier Host. I have been doing this with RH/Slic3r for almost a year. I doubt that the size, alone, is the problem. I need to slice it at 1/10 the given size, and this is what is failing.

by jon_bondy - Slic3r

cannot slice this file - 10 years ago

Sketchup says the object is "solid" and NetFabb Studio basic says there are no problems, and Slic3r does not complain when slicing starts, but it crashes silently while generating perimeters.

Re: LISA Simpson - 10 years ago

The Download All button seems to download all of the three printers. If there were a Download button for each printer, that would be really helpful.

Re: LISA Simpson - 10 years ago

Is there any easy way to download all of the STL files or all of the Inventer files from GitHub, without having to download each one separately? The GitHub UI is not helpful to me

Re: LISA Simpson - 10 years ago

Quotenicholas.seward Homing for now will consist of me pushing the carriages to the top. I have never understood why the Delta designs home at the top, far away from the stationary build plate. Seems like a design that is begging for problems. Why not home on the build plate itself?

Re: LISA Simpson - 10 years ago

I hope this has not been discussed before: I just skimmed the thread. On both my Solidoodles, and especially on my Trinity Labs Aluminatus, over-constraining the Z threaded rods ended up in wobble in the X and Y axes. Or at least that was alleged by various owners - I never personally had serious problems. At the moment, the Aluminatus has the steppers at the bottom, with the X carriage restin

Re: Aluminium RepRap with leadscrews - 11 years ago

What is the attraction of a design with a bed that moves horizontally (Trinity Labs Aluminatus) vs vertically (Solidoodle)? As a print gets bigger, the former approach requires more and more power to accelerate the bed. Seems like the latter design is inherently better, at least in this one aspect.

Thread terminated during slicing - 11 years ago

When I try to slice the attached STL file (oriented so that the printing is facing up) with the attached settings with Slic3r 0.9.10b, I get the following message: Thread 10 terminated abnormally: Math::Clipper::add_subtract_polygons: polys is not an array reference or contains invalid data at line 114

Re: Openscad measurements - 11 years ago

The only reference to units in the OpenSCAD documentation is in linear_extrude, where it states that the height of the extrusion is in mm. It may be that everything else is unitless, but it is not very helpful to have some of the program be unitless while another portion is not unitless. When I create a polygon and then do the linear extrusion, the height of the extrusion is clearly incompatible

Re: The Disappointments and Failures of TrinityLabs Aluminatus - 11 years ago

I understand how frustrating it can be dealing with Trinity Labs, and with Ezra, but when my Aluminatus finally arrived, he called when I got in trouble, and the printer is now working very well. When I was having problems with my hot end, he researched the problem, and offered to send me two replacements, overnight. It turned out that this was not necessary, but I was impressed by his offer.

Re: backlash compensation - 11 years ago

backlash compensation - 11 years ago

Does Slic3r provide any way to compensate for backlash, especially in X and Y, either by adding in the backlash on the fly, or by always approaching a given coordinate from the same X and Y sides?
