Re: Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

I have printed your stabilizers zemlin and they came out perfectly printed in eSun ABS+ black (which I just happened to have on hand). I installed them and they fit perfectly. So thank you for that. It then occurred to me that the same sort of stabilizer could be made that bolts to the aluminum bed ...

Re: Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

I like these. I was just about to do JetGuy's solution using copper tubing in place of the flat he used, but your solution looks... em, more professional/pleasing. Thanks for the upload. I imported the stl into Simplify3D and it came in correctly scaled and perfectly oriented. I always get the corre...

Re: Noisy rotating bed brackets due to play

Very cool and simple fix JetGuy. You mentioned this idea back in a thread about Possible Z-Wobble.

I see you don't have thumb screws to level the bed. Do you only use the Z-stop to adjust height and depend on the factory system to keep the bed level?

Re: Z Banding on N1 with V2 Hot End

I've got to ask this question and hopefully JetGuy will see it. I have been pondering the use of the four rods that are in the corners of the build plate. I came to the conclusion that their job is to hold the plate from wobbling, but apparently the plate wobbles anyway and thus the topic of this th...

Re: N2-V2 bed plate clamps

I wonder how well they conduct heat? The stuff I use is 0.5mm and is made for CPU cooling. I get it on Amazon.

Re: N2-V2 bed plate clamps

I have no issue with the binder clips, but I didn't like having them in the build volume, so I moved my Y-axis limit switch, shifted the bed position a bit, and now have a 12x12 build area that is free of binder clips. http://forum.raise3d.com/viewtopic.php?f=4&t=6054 The bed shown in the photo...

Re: N2-V2 bed plate clamps

But as EldRick has mentioned, maybe talcum would keep the silicon attached to the build plate. Or maybe there is a heat tape on the market that only has one sticky side. I'm way too busy to investigate but I am interested in an even better solution. Maybe something like this? https://www.mcmaster.c...

Re: ABS print settings

I use the .020" (half-mm) thickness of PEI (Ultem brand) with the frosted surface up, from cshyde: http://catalog.cshyde.com/viewitems/3d-printing-materials/ultem-pei? They offer it with the back side adhesive already applied (with no wrinkles or bubbles) which makes applying to the glass easi...

Re: Finally got dual-extrusion working...

Very nice! Very well done on the persistence to get it working correctly. Note that if you do anything that loosens the nozzle or printhead in any way, you will need to remeasure your x and y offsets to the right hand extruder. So no changing nozzles unless you are willing to recalibrate everything....

Re: Gizmo Dorks vs. Buildtak PEI

If your 3M adhesive peels after heating up, most likely the surface was not clean enough. Now having said that, I am writing here about my experience with glass and not aluminum. I clean the glass thoroughly and do a final lint free wipe down with grain alcohol. Then, do not touch the part of the su...

Re: N2-V2 bed plate clamps

JUST WANT TO ADD... Isn't it a great engineering solution to use super simple and already existing parts - like the clips - that work (well might I had) , costs less than the engineering and design solution most proper companies that have engineering control procedures go through? I think so. Guess...

Re: N2-V2 bed plate clamps

Nice idea using the stops for the y-slide. I have actually never encountered a problem with the glass sliding in that direction. Was that the problem you are solving? You still have the clips to contend with. That was my main gripe -- I kept hitting the clips with my body, the nozzle, or a tool and ...

Re: N2-V2 bed plate clamps

I'm going to predict that the nozzle will someday run into those clamps. It runs into the binder clips too. To get around this problem I have tried a number of solutions including drilling holes in my glass build plate that index to pins sticking out of my heater bed. The pins do not go through to t...

Re: LIN_ADVANCE = better extrusion control

Don't know if it helps with your "zits", but M900 K20 seems low to me. For ABS I have been using K80. Yeah, I noticed that. When I run the gcode for the K-Factor Calibration Pattern, anything below 20 or above 25 is a bit of a mess on my end. The bottom rung is the "0" and each ...

Re: ABS print settings

I print ABS on 1mm thick PEI 3M taped to glass. Depending on the brand of ABS I print with a nozzle temp of 240 - 255 with my 0.6mm nozzle. Bed temp is 105C. My prints are anywhere from 3 to 8 inches in diameter and most of that surface area is stuck down really well. I use a skirt to hold the alcoh...
