Re: Filament sensor

As I said, the switch is easy. But, it has to ask the software to calmly pause. The switch has to be wired to something.

Re: Filament sensor

The switch is simple, but it has to connect somehow to request a stop within the next 10" or so of filament.

Filament sensor

I haven't added this to mine, especially since it's not here yet, but... It would be nice if there was a switch to detect end-of-spool and then execute a non-panic pause with beeper. The filament could then be swapped out and the print continued. Not that any of us have run out of filament or not us...

Re: LED's flashing when Hotend/Bed powered up.

You can parallel two constant current devices to get 20mA.

Box, outside, think.

Re: Introduction + question

With the mention of using waxed wire-tie string I'm surprised that the author made little ties with it instead of running half-hitches. That's how I was taught back when dirt was young.

Re: flickering LEDs

Some lighting applications use regular LEDs (often T1-3/4 or 5mm) and some don't. Some have constant current chips in them, some just use resistors. We have a grow light over our fish tank that has a large number of standard LEDs in series/parallel and all run off one constant current power supply. ...

There's always these guys for bearings too.

Sometimes they'll have the bearing priced individually and then again by the bag/box for less.

In reality it would probably be ceramic. Could even have the heating element embedded in the matrix.

Re: Raspberry Pi on Rostock MAX

Since the processor is a normal Atmel part, they could write in normal programming language like C and only provide the binary to load in. On things we make that are closed source I go one step further, the binary firmware updates are encrypted and I disable the default boot loader on the processor.

Re: Rough Build Surface issue

You can also get a spool of music wire just under your nozzle size. Cut a piece that is at least a couple of inches longer than the path through the hot end. Make sure the ends aren't squished, may need to sand. Remove your tube, heat head, stuff wire in nozzle and push up through until it pokes out...

I see the MatterControl software stores at least some of the configuration on the local computer. As we have mechanical software on three machines I'd like to be able to save G-code to SD from any of them. Is there a convenient way to keep all three machines in sync?

Re: Waiting for delivery

Keep in mind that while you can print food-grade plastics, the printed result is NOT food safe. Bacteria can hide in the nooks and crannies (and layers) of a 3D printed part. Printing the fan shrouds are a good set of first prints for the machine. :) g. Hiding bacteria is always a problem with anyt...

Re: LED's flashing when Hotend/Bed powered up.

The reason you see so much 12V noise is the typical computer power supply only monitors the 5V output and keeps that accurate. The 12V is sort of a byproduct of making the 5V. It used to be if you didn't have a 20% load on the 5V supply they'd over-voltage and trip off. I STILL use small DC-DC conve...

Re: Loctite trouble

Steppers normally have the shaft exposed at the rear to allow pressing on pulleys. Set the motor on spacers so there's support under that shaft, like a short bolt or something. Then you can use a press or small impact to break the pulley loose without putting any stress on the bearings. Also, placin...

I could always cheat and print them on the Afinia, or is that sacrilege? I don't want to find a group of RMax owners with printed pitchforks at my door.
