Re: WPA2 Security Vulnerability

If wired Ethernet is slow, the 2 potential known issues are that Ethernet wired is an extension cable from the pcDuino to the external jack on the machine and/or compatibility with your cabling and particular switch or home router to negotiate the cable rate. We have seen a bad extension cable and v...

Re: WPA2 Security Vulnerability

Again, just some notes on this. If concerned, you can simply turn off the wireless network function on the printer until this is patched. The wired network connection is not vulnerable to this specific issue. There is also a likely hood your smartphone, many tablets, and other devices have the same ...

we need to confirm with our supplier of Wi-Fi chips first for more details Vicky, no this is not a hardware chip issue. This is a software issue with the firmware running on the pcDuino.

Re: Changing the nozzle @ N2

You loosen the fan first. This gives you access to the set screws in the heater block locking in the cartridges. You loosen all 4 so that both the heater and thermocouple can slide out at the same time. You simply pull the block down enough that the mounting head on the throat tube is out of the cen...

Re: Polymaker PolyFlex - printable? How?

And sorry, I didn't mean to not answer your question. In general, no, we don't have slicers go and modify acceleration on the fly. It's not that it's impossible, it's just generally thought of as making things more complicated for limited benefit. You simply tune the printer for the best compromise....

I know you are fully intending to help and a fresh set of eyes and ideas is generally good. The problem is, you don't yet fully understand the system we have in front of us, you don't have the history and the other known list of things being worked on. As such, many of you new users are quick to jum...

Re: Changing the nozzle @ N2

Before you ask why sealant or an o-ring is not used to seal the nozzle: Between the hydraulic pressure of several hundred pounds per square inch inside the melt zone and the high enough temps to melt plastic and TPU rubber- that's why you cannot use sealing compounds. The seal must be metal on metal...

Re: Changing the nozzle @ N2

Before you ask why is the throat tube small and thin- this goes to basic extruder theory and why I call it and and am trying to help the terminology- the thermal barrier. The throat tube screws into and mechanically connects the hot heater block and nozzle to the rest of the hotend and extruder asse...

Re: Polymaker PolyFlex - printable? How?

What can be the reason? Some mechanical instability? Ringing is flexing the rods due to dynamic acceleration. You have a dual extruder N2 or N2 Plus right? That model (N2 series VS N1) has the longest XY rods in the XY mechanism and the heaviest extruder head assembly being a dual. As such, the fas...

Re: Changing the nozzle @ N2

It's not that you cannot do it in place, but it first requires understanding what you are doing, what you cannot do (put torque or bending force on the throat tube), what the critical design and assembly steps are. For example, you could do it in place IF and only IF you have a way to hold the heate...

Re: Changing the nozzle @ N2

Well, the alternative is doing it wrong, putting torque on the thermal barrier tube, snapping it off mid process, not getting the nozzle tight and getting a leak.

So yeah, taking a couple of minutes to do it right, not damage an $80 hotend assembly, not cause a leak and make a massive mess.

Also, just a note about the stock stepper drivers and that alternate motor linked.

Stepper motor current is often rated by the manufacturer of the stepper...

Re: Hot motor

In general, you won't damage the stepper driver by miswiring to a motor. The problem comes when plugging or unplugging while the stepper driver is energized. The stepper motor is just a coil of wire but a coil of wire is an inductor. If the driver is powering the coil at the time of plugging or unpl...
