Re: replacing nozzle fan on N2+

You can, unplug the fan on the side of the breakout board or turn off the printer during repair operations.

Re: replacing nozzle fan on N2+

Also, when replacing, attach this sticker (may need to be scaled or adjusted to match the holes). Created by user "Eighty" in the old MakerBot forum years ago https://groups.google.com/d/msg/makerbot/KYpKaSjLhlo/0dU7DmkUThgJ AluSticker.jpg Just saying, this is the most common way to break ...

Re: replacing nozzle fan on N2+

Standard fan is a 35x10mm 12V fan. Jut about any fan within standard catalogs will work, connector is 2 pin JST-XH series. Also, read this thread http://forum.raise3d.com/viewtopic.php?f=4&t=903&p=8548&hilit=replacement+fan#p8548 And this one with even more details http://forum.raise3d.c...

Re: long pause feature request

Again, back to the basic request at the start of this thread which basically says we as users want more control over the exact script run when pause is executed. This request is not alone in that a few other features from the touch screen follow the same basic pattern, a logical button on the screen...

Re: long pause feature request

Cut your STL file into smaller logical sizes that print within time periods you can monitor Sleep beside the printer or hire folks to watch long print jobs in shifts Use the firmware source code- make the the simple edit to disable the timeout, flash your own firmware from source.

Re: second nozzle main nozzle

Also, some other basic facts about your question and PVA. PVA is a relatively difficult material to 3D print with regardless of printer brand or model. Pure PVA filament absorbs moisture right out of the air and changes properties making it less stiff and more sticky in the filament path leading to ...

Re: second nozzle main nozzle

Well the first tip is, if the filament drive section is getting hot- AKA hot motor problem, solve the problem- the motor should not be getting hot enough to deform filament. Changing the side you extrude from won't fix this problem.

Re: long pause feature request

I'm not telling you to print unattended.
In fact, quite opposite, I'm telling you limitations of the version 1.1.1 Marlin firmware and system as a whole.

WARNING!!!!!! Current issue in 1.1.1 marlin firmware that any pause with no action in 60 seconds the steppers time out and lose position. I don't blame the user for not knowing this, I blame Raise 3D for not making this obvious and warning users or fixing the problem. Can we get an official firmware...

Re: thermal runaway protection

Correct, I have shown a reverse engineered pinout labeling of the mainboard. These have been tested and verified several times. As stated, both leftmost pins are 5V and you need to run individual resistors to the 2 analog thermocouple pins (TC0 and TC1) because they need to be independently pulled u...

Re: wipe tower issues

Again, looking at your purge/wipe tower, to the problem at hand, I see telltale burned drips indicative of a leak and burned plastic dripping. That's a hardware issue, not a code issue. At the same time, for the total height and size, that purge/wipe tower needs to be 3-4 times the size to survive t...

Re: wipe tower issues

What materials (ABS, HIPS?) and why dual extrusion? Sorry, my preview of the object on this laptop is messed up but I did see a second material used as a raft base. My first notion is, you are making this way harder that required to print this specific part, but I could be wrong. Again, just saying,...

Re: wipe tower issues

Also, what worries me about your little ooze problem is that you did not show the rest of the print (the actual part you printed) along with the tower. It makes troubleshooting this harder. This is highly unlikely to be the gcode but without a picture that's why they are asking for it to see if this...

Re: thermal runaway protection

Again, just understand what this mod does. The analog pins for T0 and T1 (left and right analog thermocouple pins from the output of the AD597 on the extruder breakout board) has no pull up or pull down. The pin likes to stay at whatever the last voltage read was in the event the ribbon cable comes ...

Re: thermal runaway protection

This is a hardware issue that firmware cannot fix. You can... #1 add the 2 each 1 meg resistors to the mainboard and solder them- thus ensuring the mainboard itself detects the error instantly regardless of firmware. This is the safest option but also requires soldering. #2 you can make a plug in ad...

Re: Layer Offset after resume printing

Second is, power loss recovery is not meant to be perfect. Understand that the fact it works at all is pure luck as there are a number of assumptions at play. These are: that the part does not warp or shift while the power and heat are off, that the homing sequence is perfectly accurate and repeatab...
