Re: Printable Parts for the MK3 are released

It's expensive in that it's a full quarter of what my printer has so far cost!

One would of course hope a fuse fails open circuit. That’s what fuses do, by design. If it failed closed circuit, it wouldn’t be a fuse, would it?
I was referring to chumm's post further up.

Re: Printable Parts for the MK3 are released

Looks like they cleaned things up nicely. Shame those Bondtech gears are so expensive.

PWM to limit current is the way to go.
PWM doesn't limit instantaneous current. Passing twice the rated current through something repeatedly is not a good idea, even at a reduced duty cycle.

Also, I'd hope your fuses fail open, not closed..

Re: Thermistor Noise

Don't use a RAMPS. Presto, noise gone. More seriously: The RAMPS layout is a joke - you're likely seeing ground noise from the stepper drivers. Even if the layout weren't that bad, the headers on the Arduino aren't much better. So it really is a power issue. You could try tacking the wire directly o...

Re: Dolly Configuration

If your probe is too high above the nozzle, and the bed is that tilted, you could easily be pushing the bed with the nozzle before the probe triggers. Get the probe closer to nozzle height, and level your bed out properly - the probe is to find a leveled bed and compensate for imperfections, not all...

Re: In-depth look at the Einsy from Prusa's MK3! #TCT2017

To view the actual schematics you need Altium Designer. It's, uhm, quite expensive. Stretches 'open source'. I suppose it could be the more affordable Circuit Studio, I'm not sure if there's a practical way to tell the difference without, well, owning one of them. Thankfully they at least publish a ...

Re: Things to think about if you are going to buy a Anet A8

Not sure I agree about the stock PSU being capable. The PSU on my first A8 died within 2 days. Assuming no crib death, anyway! Mine only gets moderately warm when holding the bed at 110C and printing, especially once you get up to temperature and the bed resistance goes up, 240W is enough power. Cr...

Re: Things to think about if you are going to buy a Anet A8

Two power supplies is, uh.. unneccessary. Again, stock one has all the power needed, and your extra one.. even more so. Restraining the leadscrews will just make wobble worse - make sure your leadscrews are straight, adjust the motor and nut positions to get them to run parallel to the guide rods, a...

How much heatsink were you using at the time?
