Re: LIN_ADVANCE = better extrusion control

Just want to say thanks for all the hard work and improvements you are making in firmware for the group. I would love if Raise 3D worked with you on the new Pro series. You are very welcome. My efforts is only a fraction of your great contributions to this forum :-) I really enjoy LIN_ADVANCE mysel...

Re: LIN_ADVANCE = better extrusion control

PID autotune worked OK for me, but the temperature wasn't updated in the touch display. This was caused by the temperature reporting format from the motion controller wasn't updated (or rather downgraded to the old format that the touch computer expects). I have now corrected this in the firmware fi...

Re: Motion controller blower noise reduction by Vernon Barry

There is no strict need for a regulator, just use two small 0.5W 10 ohm resistors in series with the blower wires. This has worked for me for more than a year: http://forum.raise3d.com/viewtopic.php?f=4&t=1337&p=11918&hilit=blower#p11918

Re: 3rd party PLA clicking/heat creep?

Check your hotend for a blockage. Heat the hotend and push down the steel rod that came with the printer. This, and also check the condition of the nozzle itself. You might have a damaged nozzle tip because the tip accidentally hit something. A damaged nozzle orifice will not prevent you from makin...

Re: PETG Settings

Model fan: It all depends on what you are printing. If you need great details, rely on bridging and good overhangs, then, at least with PrimaSelect PETG you need to compromise on optimal layer bonding either by reducing the nozzle temperature or adding fan cooling. Of course, if you are printing a s...

Re: Gantry offsets

I am very happy with my current print quality, but realistically speaking, I don't know how much the tighter bushings contributes. Intuitively it cannot be good for print quality with large play in the system. Maybe it is mostly psychological, there is no more rattling from the system when printing ...

Re: Gantry offsets

As I wrote, gradually increasing the shim thickness in steps of 50 µm until free movement was obtained over the full print area. If bearings and bushings have significant play, then this method cannot be used, of course. Currently I have no play in bearings and bushing I can feel or hear. Maybe thes...

Gantry offsets

I would like to report an "issue" here, that I think is relevant for users struggling with the printer head not moving freely over the print area. Over time I have gradually reduced the play in the printer head and the gantry by replacing the stock bearings, bushings and rods with better q...

Re: PETG Settings

I have a single extruder printer that has a dedicated model cooling fan on the right side. I use a custom fan/duct, but also the stock printer has this model cooling fan that can be controlled from firmware. For a dual nozzle printer I guess you have to adjust the air flow by the small flap on the b...

Re: PETG Settings

The reason I went "down" to 230 deg was to improve overhangs, but if you don't need good overhang performance then it is probably better to prioritize good layer bonding. In my experience, going below 230 gives worse layer bonding and better overhangs; going above 230 deg gives better laye...

Re: Integrated Filament Run-out sensor

That's exactly true. It is the curved shape of the filament that creates the friction. I have tried to mitigate the wear by extending the 4 mm PTFE tubing all the way down into the casing. That means that most of the "straightening" take place inside the PTFE tubing. The PTFE tubing last f...

Re: Integrated Filament Run-out sensor

I used a Sharp sensor with a Near Infra Red LED at 950 nm. If you mask half of the filament diameter and place the the optical sensor accurately, then you can rely on refraction to obtain a quite good discrimination.

Re: Integrated Filament Run-out sensor

This is my own design with optical sensors. I use the P2 connector on the main board and I suspect Raise3D will do the same for their optical sensor offering. P2.jpg E.jpg I bought the cheap ones with the metal inserts that you have shown. It requires quite some force to pull the filament through it...

Re: PETG Settings

Extrusion width is used by the slicer to calculate how close it should put the extrusion lines. The slicer will adjust the flow rate accordingly. For example, if you need to fill a 2 mm wide area, this can be done by using 5 parallel lines of 0.4 mm extrusion width or 4 parallel lines of 0.5 mm extr...

Re: LIN_ADVANCE = better extrusion control

Yes, you need to enter all parameters in this script, but the parameters should be trivial when you know your printer, the type of filament, your nozzle temperature for this filament etc. The LIN_ADVANCE feature doesn't make wonders, it's more a fine tuning if you want to squeeze the last bit of pre...

Re: LIN_ADVANCE = better extrusion control

Yes, that's all you need to do. Your CUSTOM_MACHINE_NAME was commented out, so I didn't include that. LIN_ADVANCE_K was set to 0 in your Configuration_adv.h file. I think this is how it should be, as you need to set it from g-code dependent on the filament type you are using. I found that there's a ...

Re: Limitations of spiral/vase mode

It depends a lot on the layer height. If you have 50% overlap with the previous layer, then you are safe. That requirement boils down to the relationsship between layer height and "maximum overhang angle" shown on the plot below. As you can see, for 0.2 mm layer height it is safe to use 45...

Re: PETG Settings

I think those "zits" have nothing to do with oozing. It seems to be extrusion line start/stop points. You can collect those at a certain corner of your model by setting "Layer Start Point Type" (ideaMaker) or "Choose start point closest to specific location" (Simplify3D...
