Re: Polymaker PolyFlex - printable? How?

0.8 mm is not the minimal step, it is the x/y distance corresponding to the angle between two motor poles. Imagine a rotor pole "suspended" in the magnetic field from two stator poles. The rotor will position itself in this magnetic field according to the current applied to the electric co...

Re: Polymaker PolyFlex - printable? How?

Well, it's good that Raise3D is taking notes, but it will not be possible for a slicer SW to mitigate ringing, the reason being that the slicer has no idea of the phase of the oscillations, i.e. the position of the ringing. The slicer and the motion controller can limit acceleration, as is already d...

Re: N2 "Failed to join WLAN"

You could try to change the channel that your Access Point uses then and see if it helps. Don't know if there could be strong interference from other WiFi networks in your area that disturbs the communication. There are free apps for the iPhone you can download and "analyze" the wireless e...

Re: N2 "Failed to join WLAN"

Does the printer see the available networks and show them on the display? If not, the try to manually key in the SSID and pass-key of your WiFi access point. I have experienced that the printer not always finds and displays the available WiFi networks, but can still connect if you tell it the SSID. ...

Raise3D did it!

Don't know if this is a serious challenge or not, but I think it shows that Raise3D printers are among the best in printing precision. No other FDM printer (besides my N1) have reported a successful print of this spinner: https://www.youtube.com/watch?v=TYuLVN3YHw8 One guy reported success on a Stra...

Re: Buildtak problems - nothing sticks to it

Take a look at this:
http://forum.raise3d.com/viewtopic.php?f=2&t=1543&p=13167#p13149
If the Buildtak "dies" it's probably because you used filament materials not suited for Buildtak. If this happens it is not sufficient to clean it using alcohol.

Re: X-axis skipping steps

No one is questioning that this is x-axis step skipping. Jetguy is just giving a very likely explanation as to why this happened. Over-extrusion makes the accumulated layer height grow and grow and when the nozzle tip hits the hardened plastic you might see a stepper skip. Stepper skips are always m...

Re. Stiffness of the "thin rods". It has been mentioned earlier that there is a problem with the stiffness of the 8 mm steel rods. The theory is that the load from the printer head will cause the rods to bend and thereby affect the dimensional accuracy of the printed parts. Some time ago I...

Re: Issues Expected for a Raise N1 or N2

I am very happy with my N1 printer. I didn't regret buying it, despite the issues I had with it. The main one being that the heated bed was unusable when heated to 110 C. My post about the modification I had to do in order to get the bed working decently: http://forum.raise3d.com/viewtopic.php?f=4&a...

Re: Shorted heating cartridge & maybe board

I doubt very much that this black mark on the heater wires has anything to do with your fault. These heater wires are very large diameter wires and they will require a lot of current to melt. Even if there was a weak spot on the wire here and it really burned over, then you would only see that as mi...

Re: New heat shield design

OK, maybe it would make sense to apply tape for protective reasons. It might be easier to peel off melted plastic from the kapton than from the PC. If this was the intention of the kapton tape, then I apologize to the OP for the accusations. My general remarks are still valid though. There seems to ...

Re: New heat shield design

Good that this blower duct works for you, but I think your design is a little misunderstood. Why would you want to put kapton tap on the outside of you PC based blower duct? Thin kapton tape is not an insulator by itself. The reason that some people like to use kapton tape on their hotends is that t...

Re: X limit switch location

Price and quality are two interesting variables. Sometimes you get poor quality because a manufacturer deliberately prioritizes low manufacturing costs and sells a very cheap product. This choice is kind of acceptable, you get what you pay for. Sometimes however, you will get poor quality when it wo...

Re: Bad adhesion of Buildtak

I never used any extra glue or stuff on the BuildTak and I have excellent adhesion of the first layer print for PLA. For large items it's nearly too much adhesion as it's sometime difficult to remove the printed part from the bed. I also never use rafts, as I like the nice surface I get from printin...

Re: Bad adhesion of Buildtak

You cannot get anything to stick on any surface if you use the Raise3D recommendations of using a z-gap of 0.2 mm, at least not if your first layer height is 0.2 mm or below. All slicer programs assume that there's 0 (zero) gap between the nozzle tip and the bed surface. The Z-position for printing ...

Re: N2 plus not a great experience before even printing

Monty, it's very scaring to watch your video. I think you are too hard on that poor printer, applying so much force to the printer head. It might be that your gantry is out of adjustment, but even if it isn't, then you have tight tolerances in your slider block bushings and sometimes it can be diffi...

This happens to me also, that the BuildTak stops working. I have had great success by sanding the BuildTak surface slightly with a grade 240 sandpaper. I use a flat sanding machine, but a hand sander will also work. Then I thoroughly clean off the fine dust using soap water. The BuildTak will work a...

Re: Touch screen and calibration issues

The capacitance of your body to the surroundings will be normally more than sufficient to trigger the capacitive sensors of the touch display. The effective capacitance, as seen by the touch display, will not increase significantly by you touching a grounded surface. Despite this, it might still hel...

When you select a gcode file for printing on the touch screen, you are asked to confirm the selection. In this screen it would be nice, if more space was allocated for showing the file name. I have a habit of embedding quite a lot of information in the file name, but often I cannot recognize the fil...
