Re: Upgrade Option Questions

So, Let's try to get things in order: Do you need anything beyond the base kit for the raspberry pi mounting? Yes, You want 4X of the board standoffs , and IIRC, you may need to buy or get a small amount of wire for wiring it up. Nothing major. Can you send G-code from S3D to astro/octoprint or any ...

Re: Brand New Rostock v3 build stringing/oozing

There's an old thread on this, here . Yes, that is a thermocouple. You can also get a multimeter with a thermocouple connector, which may be more useful if you don't already have a multimeter. Once it's calibrated for accuracy, I would suggest setting it to print a few small pillars at a time, since...

Re: Rostock V2 Thermistor Negative Tempuratures

Thermistors are not linear devices. They are also imperfect. The ones used in 3D printing are chosen for stable high temperature performance and to be sensitive and usable at the temperatures required. Room temperature sensing is therefor only approximate. You might have a cold solder joint increasi...

Re: Upgraded E3D v6 - High Ambient Nozzle Temp

I would check the resistance of the thermistor wiring at a few points, and find a thermocouple to look at your actual temperature with. Most likely you have a partial short somewhere, meaning a small solder bridge, or some other relatively high resistance short. Also, the smoke from the hardened ste...

I suspect a portion of it is the temperature and cooling settings, in addition to the retraction based on that specific filament being different than the general starting point we recommend.

Re: Rostock MAX v3 Crash with Dual Extrusion

Welcome to implementing complex projects in Arduino (Or anything really). A change in the build environment can cause really astoundingly strange behavior, and unfortunately, Arduino occasionally lets them through without throwing the correct error.

Re: High strength filament recommendations?

Unless you need food safety, use the hardened steel. It has a better heat transfer coefficient (typically, there are so many kinds of steel that I could find you a hardened one with a worse one than a stainless, but E3D wouldn't have done that), and it is more wear resistant and cheaper.

Re: Why you should NEVER use SketchUp, which is a steaming pile of crap.

A few things to mention on the threading: Trapezoidal threads get broken occasionally, although more often DIN 103 than ACME (This is fixable by editing a few config files full of thread definitions, and you can add your own thread profiles to the tool). For most files and applications, use the defa...

Re: After calibration, first print is good, all other prints fail

The pulleys may also be slightly loose, or the idlers loosing tension. There is also the very real possibility that your endstops are moving slightly, or the screw which triggers them is. As for attaching the accelerometer, you can place the wiring up the outside either around a dowel or bar, or ins...

Hutch, USB supplies 5V, which unlike the rambo, is not isolated from the board power, so while plugged into USB, whatever it's plugged into is supplying the 5V power.

I think you'll be best served by giving DC42 a holler, especially if it's a Duet Wifi/ethernet board. It may be that the 7 inch panel was a little too much draw for the 5v regulator, or something else connected to it (Perhaps the fan voltage as pulling from the 5V?). He would know the best way to ge...

Nope! I'm sitting on top of a pile of hardware mods (hell, even the stepper motors have cooling fans). I probably should have just made you a reference config. I'm using a bondtech, and do indeed have a heated chamber. My apologies.

Re: Hotend cannot get to 240

That's a bit low from my perspective. PID on a rambo works best around the operating temperature it's tuned to. If you picked 220-230, that may work a lot better than tuning at 200. Tuning at 240 would be best, but with the original PEEK based hotends, the potential for overshot damaging the hotend ...

Re: Hotend cannot get to 240

At what temperature was the tuning started, and where was it run to? Different set points want different PID's (And the Rambo's autotune model, while nice enough, has some rough spots with that).

Easiest way would be to order replacement terminals ( these ones, probably), then desolder it and solder on the replacements. Plus use ferrules on the wire (And definitely not solder), to give it a better surface to grip on.
