Re: Bed leveling?

Do a couple of keyword searches (Sag and deflection) and a lot of reading, you slowly get the hint why this design has some limitations, why since the kickstarter different folks had different ideas on modifications. It's pathetic the pro2 ...

Re: Bedplate Leveling

What is your dial indicator mounted to? My guess is they left the adjusting screws off the center so that it "sags" a little to perhaps mimic the sag of the head/rods when its in the middle. If your indicator is mounted to the extruder, the extra weight may be sagging ...

... travelers? I turn the ends down to 8mm. Lastly, you don't need less moment. Again, read what I wrote. I was using hollow carbon fiber. It had no sag, weighed 1/2 the aluminum rods weight and got me no performance improvement. I did extensive testing of a variety of rods using a digital force ...

How I more than doubled my print speed while increasing accuracy

... entire moving XY print mechanism. There were other good reasons why CoreXY would be better. One is that the weight of the current gantry causes sag from its own weight. Thus it is literally impossible to print a flat object: The closer the printhead moves to the center, the more sag due to weight. ...

Bed Level Issues

... have never been able to get the bed level. No matter what I do, there is a high spot in the center of the bed. At first I thought it was just rod sag due to the anemic 8mm rods (I'm sure that contributes to the issue). I placed a flat piece of machined steel on the center, and it does rock just ...

Re: Another topic about a gap

... for 8mm diameter rods and an estimate of the weight of the gantry - I don't remember the exact numbers, but they were comparable to the gantry sag of the N2 printers. I don't, however, find that this leads to any warping of parts, as it's only very small amount of sag. With larger parts and ...

That leakage could explain why a 3.3V pullup high value resistor like a 1meg could sag and only pull up to about 2.4V, or, say they did use a 5V pullup and again, for whatever reason clamping to prevent ADC damage limits the voltage ...

Re: glass bed can't be leveled because it's not flat :/

Or you could just get a Bondtech extruder, and save a kilogram that is making the rods sag, while getting more reliable and accurate extrusion.

Re: glass bed can't be leveled because it's not flat :/

... than ask for a replacement? There are 2 causes for high spot in the middle. One is your platform has a bulge in the center, the second is rod sag from the heavy extruder. Glass is almost always flat (you probably adjusted the platform so it bows down which is why the glass isn't flat on it) ...

Re: Temperature does not rise

That is when you would see the P value allow sag, and then depend on the I value to see it sit there not rising in temp and kick in a little boost and finally reach set temp. That's the good thing ...

Tubes or no tubes

This is the question, Tubes or No Tubes... I have found with the tubes on, the weight of the tube and filament cause the unused filament to sag as I am printing. I have taken these tubes off and find I have the same problem the unused filament ( if I only use 1 filament to print ) tends to sag ...

Re: BTSN2 Build Plate for Raise3D N2 Printers

I think the issue is actually the print bed or extruder sag. With the glass the corners are a lot lower than the middle. Almost 2mm lower. With the BTSN2 plate, the difference is much less obvious but it's still there. I'm reading through lots of threads ...
