Re: Raft/Support material? - 14 years ago
Of course, but I don't think the support-detection math is that mature yet, as it has only just been introduced. Think of it as a beta feature, give it some time and it will become more advanced.by Nudel - Slic3r
Re: Raft/Support material? - 14 years ago
Not a very good example, as that bridge is no problem to print without support structure, and I would assume Slic3r takes that into account.by Nudel - Slic3r
Re: how to add fan for extruder? - 14 years ago
If you are planning to cool the hotend to shorten the melt zone and lower the temperature of the x carriage (useful/required with PLA), you are better off running the fan at all times, or wire it together with the hotend resistor. If you want a fan to cool down the print itself (very useful for small parts, overhangs and bridges), yes you can control it with RAMPS. Where you attach it would depeby Nudel - General
Re: How to find stepper drivers microstep setting? - 14 years ago
On the Pololu drivers (the A4988 is a drop-in for A4983), you control the microstepping by grounding the pins MS1, MS2 and MS3 in different configurations. On RAMPS there are jumpers under the Pololus to control this. Read more here:by Nudel - General

Re: help printing - 14 years ago
Either your e_steps_per_mm is a bit too high, temperature is too high, or retraction is not properly configured. Try different "Retraction Distance", and lower/higher "Extruder Retraction Speed" in Dimension in skeinforge. You can post your settings here and we'll suggest some changes. It can also be worthwhile to try out SFACT or Slic3r.by Nudel - General
Re: 0.7.0 Feedback - 14 years ago
Thanks Sublime, that worked perfectly! The tick box in my sf is "Go Around Extruder Off Travel", I'll look into it to try and find the exact place where if retracted excessively.by Nudel - Slic3r
Re: Cooling - 14 years ago
Maybe your fan won't start up at the default 35% speed? Try increasing it.by Nudel - Slic3r
Re: Raft/Support material? - 14 years ago
Ah, must've misread that, sorry. But yes, I do get support for angles close to ~80-90 degrees. Try out this openscad snippet to see it generating support. Not useful to print, but you get the idea. for(i=[1:19]) rotate() translate([15*i,0,0]) cube([10,10,50]);by Nudel - Slic3r
Re: Quality of MendelMax vs Ultimaker - 14 years ago
If sheer overall quality is the main concern, I'd vote for the MendelMax, simply because it isn't limited to bowden cable and thus have tighter control over extrusion. I'm very impressed by the quality people are getting with bowden, and the software compensation have come a long way. But on tiny parts requiring a lot of short retraction moves a bowden cable will string more than a extruder closeby Nudel - General
Re: 0.7.0 Feedback - 14 years ago
Version 0.7.0 produces beautiful gcode, as always, but I've encountered something weird. After filling in a bridge area (top right hole in the gregstruder body) it did a very long retraction move, messing up some of the perimeter for the next layer. I've tried to decipher the gcode, but can't find the error. It happened at or very near the end of layer Z6.6 (close to layer Z6.9). I tried using sby Nudel - Slic3r
Re: Raft/Support material? - 14 years ago
With a proper heated, level build bed, rafts isn't and shouldn't be necessary. With tiny parts, and the rare occasions where it's needed, add a base to the model manually.by Nudel - Slic3r
Re: Wiring - 14 years ago
Only one pair of for the extruder? Isn't that too low for the current we run through it? I've had my extruder connectors corrode, which were far more beefy than rj45's, and now only use fat wires with deans connectors for both the extruder and bed heaters.by Nudel - General
Re: Wiring - 14 years ago
It's the first time I've seen it closed, he must've been swamped with orders suddeenly. Kind of weird you can't browse though. But closing mdpc when he reach a high amount of orders in one day is his way of running his business, and I respect that deeply. It avoids the insane backlogs we've seen from several RepRap shops.by Nudel - General
Re: Wiring - 14 years ago
I can highly recommend for low cost super-high quality cable sleeving and accessories. It helped make the cable mess of gen3 remix set look somewhat decent, until I started hacking it without using sleeving, that is.by Nudel - General
Re: Have Slic3r 0.7.0 a BUG ?? - 14 years ago
I can confirm it behaves a bit weird. I can slice it fine with my previous tweaked configuration profiles (0.35 nozzle 0.3 layer height), but with default values it refuses to print the perimeters on the top pegs.by Nudel - Slic3r
Re: Solid Model files for Prusa Mendel - 14 years ago
I don't know solidworks, but using a mesh modeller like wings3D with a few tricks up its sleeve, it's really quite trivial - depending on the model - to clean up stl outputs from openscad so it's easier to modify them with other cad tools. To be honest, I love openscad, but due to its nature the stl output can be just horrible. Not worse than sketchup perhaps, but still enough for it to be visiby Nudel - General
Re: Pronterface not loading stl - please can you help me

As far as I understand, compose (aka plater.py) only opens stl and openscad files, and outputs stl for slicing.by Nudel - General

Re: Just a thought after using slic3r a bit. - 14 years ago
M220 is very, very useful. If you don't want to babysit the printer you can also edit the gcode manually and add M220 at the layer you want it to slow down.by Nudel - Slic3r

If you just want the files, click on download and fetch the entire branch in a zip or tar file. That said, it's very much worth it to learn the basics of git.by Nudel - General

Yes, you of course have to move the thermistor pins to the motherboard as well, but then it should be good.by Nudel - General
Re: Printer host and slicing software compatibility - 14 years ago
No, Marlin/Sprinter is not compatible with gen3 electronics that use a separate extruder controller board. What you need is really only a small circuit with a mosfet to control a heater, and to hook up a stepper driver for the extruder. It can be made yourself, or you can look into gen3+ which works fine (with the correct pin settings, of course). Last time I checked teacup have support for I2Cby Nudel - General
Re: Uploading/Connection Problem - 14 years ago
Weird. Double check the settings of ENDSTOPS_INVERTING in Marlin. Also note the endstops are only looked for while homing, not during regular moves, you can comment out ENDSTOPS_ONLY_FOR_HOMING while testing if you want.by Nudel - General
Re: Sprinter z axis motor normally off? - 14 years ago
I would advice against it though, since we run two motors off one stepper driver, and the motors draw the most current when locking, I would think it could potentially have some ill effects? Have anyone looked into this? Edit: Seems to be no problem, read below.by Nudel - General
Re: Sanguinololu electronics - i need help ! - 14 years ago
Try the precompiled pronterface. It should have everything ready to go in an easy to use package. If/when you want the newest version of prontertface, download it from github and follow the readme to install the needed dependencies.

Re: Sprinter z axis motor normally off? - 14 years ago
That is correct. The friction of the threaded rods is enough to lock the z axis, so no need for the motors to draw power and generate heat when not needed. If the z axis was driven by a belt, a rack-and-pinion system or certain lead screws, the z motors would have to be enable to avoid the axis dropping down. I understand there is a minuscule delay when switching the motors on and off, which caby Nudel - General
Re: Marlin serial errors - 14 years ago
Have you tried increasing the baud rate to 250k? That did the trick for communication errors on my sanguinololu at least. Perhaps you can try out pronsole.py or printcore.py directly to narrow down the problem. Also, if you run pronterface.py from the console, you will see more error messages than what pops up in the GUI.

Re: question for adrian and his team (reflow video as well as other) - 14 years ago
You can find RepRapPro sources on their github. The bed in the video looks like this one. According to the video, the microlayering is done in the host software/slicer, not the firmware. You can find the java host on github, though I have not tried it.by Nudel - General
