Re: Replacing print head linear bearings ?!?

I know all about this. That's why I just spent $59 on a complete replacement carriage with installed bearings to fix my N1. https://forum.raise3d.com/viewtopic.php?f=17&t=20199 Now that said, we can also have a debate. The N series when first released, there were 2 styles of central crossing blo...

It will NOT be the same between any 2 fans and will not be the same between any 2 printers.
This is due to variations in the fan- not the printer.

Re: Minumum Fan Speed

Perfectly normal. These DC brushless fan motors were never meant for PWM speed control. You are effectively feeding the fan with power that turns on and off rapidly. It's bad for the electronics, it's bad for general longevity. Does it kinda work? Yes, and so, rather than specific and more expensive...

Re: Why does my printer keep trying to connect to the Raise3d server

I noticed in the logs of my firewall that my printer is attempting to communicate with your server at 218.244.146.143:80. I'm going to say that's the raise3D cloud service. Why is my printer doing this, and what kind of information are you gathering? Because you loaded and are running a cloud enabl...

Re: N2 Single Extruder 2016 - Part Cooling

I could say yes or no to that question, it's still a broken concept. Slowdown as a function in actual 3D printing at the nozzle actually printing plastic does more harm than good. If you slow down, then the nozzle is not only radiating heat, but also conducting heat through the liquid plastic to the...

Re: Simplify3D Offsets - Preview vs Actual Print doesnt align

FYI, motion firmware limits to 305 regardless of what you send it. The actual hardware may or may not be able to reach that based on lost offset by the limit switch placement and so forth on some printers. The kicker is, the bed was not under the nozzle position when homed, so you lose a decent buil...

Re: Simplify3D Offsets - Preview vs Actual Print doesnt align

Actually, I should better frame this. Specific to the N series, the old way of the slicer doing the offsets was actually not ideal. Many other systems and brands (both slicers and printers) had gone to the offsets stored in the printer model of operation. It took until version 0.9.10 of Raisetouch f...

Re: Simplify3D Offsets - Preview vs Actual Print doesnt align

So, again, go into your raisetouch, figure out what system you are using, and then knowing that, THEN adjust your raise3D profile to the same system. Personally, I would leave it at offsets at the printer, so adjust S3D with NO offsets. That's the most logical as it would maintain that both Ideamake...

Re: Simplify3D Offsets - Preview vs Actual Print doesnt align

Just a reminder, this got extra complicated when they changed how dual extrusion offsets work in the raisetouch application. You need to know what version of raisetouch you are running and what defaults you have set. I say this, because the OLD way was your gcode for left and right extruder had offs...

Re: N2 Single Extruder 2016 - Part Cooling

FWIW, the cooler you linked I believe is also a good candidate. Blowers generate more static pressure airflow and thus flow higher rates through the constrictive printed ductwork. A such, this kind of does what the Berd cooler does, provide a ring of airflow around the nozzle.

Re: N2 Single Extruder 2016 - Part Cooling

Again, the root cause of this specific print failure of something this small and tall with no other adjacent objects is the slowdown and dwell time caused by minimum layer time. Even if you turn this off, it might help, but printing more copies of the object is actually the best fix in most cases. T...

Re: N2 Single Extruder 2016 - Part Cooling

And, the best cooler for this type of print if you do go down the modification path is the Berd air cooler, and that's because it provides high pressure airflow directly surrounding the nozzle with minimum nozzle cooling. But to implement the berd on a N2 is a non trivial exercise and could require ...

Re: N2 Single Extruder 2016 - Part Cooling

While you can change the cooler, let's not kid ourselves on this specific print. What you are fighting is going to be near impossible for a fan cooler to fix. Now that I've blasted you out of the water, let's understand why I'm saying that and what the real fix is. Just look at your object. The nozz...

Re: Has anyone done a 32bit upgrade to the N2 series?

FWIW, after just finding out my N1 is in bad shape from loan to the local makerspace (LCD touch not working, linear bearings shot, linear rods shot) it's a candidate for a Duet2 upgrade which I also have on hand. The difference is, the N1 has a much shorter and simpler cable path, can use a direct l...

Re: Has anyone done a 32bit upgrade to the N2 series?

Million dollar question, how did you connect the thermocouples to the DUET thermocouple board? Did you use long thermocouples or proper thermocouple extension wiring and connectors to extend the existing thermocouples through the cable chain down to the electronics bay? OR Did you remote the thermoc...

It's an estimate at best and a sorry guess at worst. Never take the estimated value as an exact time. To understand "why" you have to go down to the fundamental level of how a print file even works. A 26 hour print job with untold how many hundred thousand or a million gcode moves, all rea...
