I am fairly new to the community ( few months), so maybe I do not see it. But thingiverse seems to still be useful. Especially since nothing else exists that can take it's place (pirate bay is just not well organized

The top part with the gears toggles left or right to engage or disengage the filament and motor....don't see the toggle mechanism though.
similar principle to the way stratasys does it, but different. Still might be covered by one of their patents. Dglass3D should be sure to check into that before selling them.

this sort of thing is done all the time.
but no need to print the parts differently.
Just soak them in epoxy resin. put into a vacuum chamber and suck all the air out. Once the bubbles stop. remove the part and wipe off the excess epoxy, and let cure overnight or however long the resin needs.
The printed part has lots of little voids everywhere and acts like a sponge and soaks up the epoxy so

Automatic bed probing and levelness compensation

I had a similar issue.
pronterface does not have any control over the speeds issued by G-codes, and Slic3r cannot slow down only one axis, (the Z axis in our case). The firmware is the ultimate limiter of the axis speed, and it is not configured correctly for your specific machine.
If you use marlin firmware, or probably any others, you can easily re-set the max speed of each axis with an M-cod

there is a setting in Slic3r for "infill every X layers" or similar.....set this to 1. That might do it.

I have played with Nylon printing on The TAZ we got at work. The hotend can handle it fine, but shrinkage with the Nylon is fairly large so large parts could be a real problem. I also modified the TAZ for a little more accuracy and more rigidity (a few stiffer parts and linear ball bearings)....but that was after playing with the Nylon.
finding a good base to get it to stick to took a while. End

I asked about this very thing a few days ago.
I assume this is a MIM type material.....If so, i would like to try it out.

It's listed here:
BTW, where in the firmware (which .h file) is the actual G29, and other G codes for that matter?

Firmware - mainstream and related support
So Metal Injection Molding uses basically the same injection molding machines as plastic injection molding....
So why not have a MIM filament, just like there are plastic filaments for 3D printing?
I know that there is a large shrink rate, a de-binding step, and a sintering step that will require special furnaces, or chemicals, but I am sure that can be dealt with.
First step is to try to extr

got it downloaded, modified, and working (at least dry runs).
but it looks like G29 is the code to use, not G32. Maybe the description is messed up.
G29-G32: Bed probing
G29 Detailed Z-Probe
probes the bed at 3 points.
G30 Single Z Probe
probes bed at current XY location.
G31 Report Current Probe status
reports whether Z probe is triggered.
G32 Probe Z and calibrate with FPU
probes the bed at 3

anyone else get this working?....i am trying to add it to my TAZ.
looks easy enough, but where are the coordinates for the XY position of the 3 probing points stored? in the firmware somewhere? or do you just use g code to go to each point?

looks kind of like a knurling wheel, for a lathe.
but those are often carbide, and meant to free wheel.....still you might be able to adapt one.

Ideally the "priming part" would be only one layer high, and near the corner of he build area, so this does not happen.
But you are correct, a collision is a possibility.

ISSUE
G-code from slic3r is not in the correct position (may be a slic3r issue).
I load a model in repetier, then move it near the corner of the build area. Slice it....but the gcode shows it in the center of the build plate and that is where it prints.
by

Repetier
Instead of slicing 2 objects....simply slice one. and copy and paste the G-code into the starting g code field in the printer config. Then it will always run that little priming part code first.

what material are you printing? I have noticed some material (nylon especially) shrinks the holes WAY more than the outside.
you probably need to scale by 25.4 which is the scale factor from inch to metric (or 1/25.4 for the other way around)

"cold nozzle extrusion stopped" when viewing the second extruder nozzle temp, while in manual mode, watching a program run, even though the nozzle that is printing (the first one) is up to temperature.
found this out the hard way.
had a program running, everything good. thought I would take a look at the temperature on nozzle 2, just to make sure it was not heating too. clicked the box o

you are talking about adding an M code definition in the firmware...correct? and then calling that.

ANNOYANCE #1
you cannot change printer settings while the printer is connected anymore. The button is grayed out, you must disconnect...then the button is available.
This was useful for my dual extruder settings. since I could switch back to single extruder mode easily.
Can you add that feature back in?
Otherwise, it is good so far.

How do you make both extruders extrude at the exact same time?
simultaneous printing....
Is there a G-code command that will link them? or maybe just a Y cable on the stepper?
