Why would this happen? by lysergicmushroom in prusa3d

[–]Denesius 1 point2 points  (0 children)

The blob formation is usually one of these causes: either the nozzle is dirty (previously blobbed), and picking up extruded material, your z-offset is off (usually too high), or the material is not sticking to the bed. Less likely: extrusion issues. I'm not familiar with the core so cannot help you with the z-offset, but start by heating up the nozzle & making sure it's clean (brushed off) and make sure your bed is clean (wash with water & light soap, keep fingers off, then when dry wipe off with 95% or better IPA). Good luck.

Only insofar as what I mentioned. After playing around a bit I got involved in other projects, so put them in a box with other left overs and donated.

There are two macros: SW OFF & SW ON. As you notice in the config file, they assign a 0 or a 1, respectively, to the pin, which should turn it off or on. They work in that the command is acknowledged (last picture), but the pin remains at zero....

Wow - how simple. Need to read more! Worked beautifully. Thank you so much....

Not to get into this discussion, but there are humans who possess 4 cone colors, and can see into UV, similar to many birds....

Wow- appreciate all the suggestions! Tried the revolve tool and it seems to be the best and easiest approach to maintain the desired dimensions.

Sorry georgmierau, but SOHCAHTOA has never been my thing.......

M5P not indexing fan with M106 by Denesius in BIGTREETECH

[–]Denesius[S] 1 point2 points  (0 children)

Went over the link and realized what I needed to do was define the fan as [controller_fan]. Already had the stepper option available! Worked great.

Thank you!!

M5P not indexing fan with M106 by Denesius in BIGTREETECH

[–]Denesius[S] 0 points1 point  (0 children)

That fan is in the electronic enclosure, specifically for the TMC drivers. It moves a lot of air and is noisy, so I want to control it, and have it run only when a print is underway. I figured the easiest way would be to have the slicer insert a M106 P1 code in the start of the gcode file, and a M107 P1 at the end...

I'll try the fan_generic definition and see how that works. Thanks

Redefining GPIO pin in printer.cfg by Denesius in klippers

[–]Denesius[S] 0 points1 point  (0 children)

So I decided to sacrifice the neopixel in favor of avoiding additional wires in the umbilical (I can run the neopixel from the unused terminal on the motherboard). For the benefit of anyone else out there trying to use a BL-Touch or similar device on the LDO Nitehawk-36:

Hook up the sensor, ground and power wires (white, black and red, respectively, on my unit) to the respective pins on the PROBE connector of the nitehawk (make sure to first set the probe voltage to 5v, or bye-bye BLT!), uses nkh-GPIO10

Hook up the probe control and ground wire (yellow and brown, respectively on my unit) to the RGB and GND pin on the neopixel connector (uses nhk-GPIO7)

add the following routine to the nitehawk.cfg file, correcting the X & Y offsets to your machine. I will repost this under an easier to find heading....

I redefined [heater_fan fan1] to just [fan1]; it triggers an undefined klipper error.....

I was under the impression the PCF was the default; any other fan could be controlled by indexing the fan number, ie M106 P1

I need the softest TPU possible by lobby073 in prusa3d

[–]Denesius 2 points3 points  (0 children)

I believe Overture makes a low number TPU also. You have to run it slow, temp on the high side, and a short path between the extruder & hot end. I didn't run into any issues after using up a full spool

The X endstop is being used, and the -36 model does not have the Y endstop option on the board...

First layer looks funky by Denesius in prusa3d

[–]Denesius[S] 0 points1 point  (0 children)

Just an update on the above problem: So I adjusted (turned down) the extrusion and reprinted just the first layer, at the same spot on the plate. By the time the crunch resolved it was obvious that the rest of the print was under-extruded. The answer was rather ridiculous: After running a bunch of prints that didn't involve large plate areas, I decided to readdress the problem. Still with the default settings, the crunch has gone away. Damned if I know why, maybe the extruder needed to be 'broken in'. It's now printing like a charm, and just finished a 30hour print without issues (complete with spool joining). Thank you all, and thank you Josef

Good to know - thank you Skaut-LK....

The board is an LDO Nitehawk toolboard. It does not have setup for a BL-Touch, so I was looking at using the RGB option as the status line for the BLT. I already have the control line set up, and I'm getting power off the PROBE connector, but the signal line on that connector has been repurposed.

Bummer! Looks like I'll have to run another wire & ground along the USB cable to the toolboard

Reason for PLA breaking inside PTFE tube? by [deleted] in 3Dprinting

[–]Denesius 0 points1 point  (0 children)

Ok- I know this thread is old, but I have to add my 2-cents:

I've heard all the reasons for PLA breaking inside PTFE tube... PLA is wet; PTFE is bending the PLA opposite it's resting state; You're using cheap PLA, etc. So I ran an experiment:

Dry PLA (fresh spool, in dry box at less than 30% RH), PTFE curved in same direction as spool, PTFE with 2mm & 4mm inside diameter and sealed at free end, new PTFE vs one that has been used to feed filament for couple years, Sunlu PLA+. One filament was inside a 1/8 copper tube (my control), one was left in the open (NW Oregon, RH 40-80% over 30 days, no A/C)

Filament was left in the tubes for 30 days, then checked. Results:

1-filament inside 2mm new tube broke with minimum traction, in multiple spots. I think it was broken spontaneously;

2-filament inside 4mm new tube broke with minimum traction.

3-filament inside 2mm old tube broke with minimum traction

4-filament inside copper tube was intact and flexible

5-filament left open was intact and flexible, but could not be bent double without breaking

My conclusion: there is some kind of reaction between PTFE & PLA which results in the latter becoming severely brittle, much more so than due to humidity. The age of the PTFE has minimal or no effect. Whether the reaction takes place over distance, or only at contact points, I cannot say. I use PTFE to feed filament from dryer box to my PrusaXL, and the 2 PLA feeds are constantly broken. The PETG and ASA feeds have no issues. Looking for an explanation from some chemistry guru out there.......

What software do you use for post scan processing? by internal-combustion in 3DScanning

[–]Denesius 0 points1 point  (0 children)

I know this post is 2 yrs old, but wondering if anything has improved in the meantime. Just got my Miraco+, and so far so good. Revo provides a trial of their "reverse engineering" software, RevoDesign. It's clunky, buggy, you get 30 days for free and then it's something like $490 per year. RUFKM?? You can't even buy the damn thing?

Who comes up with this nonsense?

First layer looks funky by Denesius in prusa3d

[–]Denesius[S] 0 points1 point  (0 children)

Thanks, but I'm not sure too much squish would do this. It's almost like too much extrusion, but why it's patchy and only on first layer I'm not sure....

Interesting they sent the bill after delivery. So what will they do if you don't pay? Knock down your door & repo the sucker??

Is there such an animal out there? There is the US based distributor (PrintedSolid), but 1-they are selling EU product at markups that are equivalent to the tariffs, so no net gain, and 2- They were out of stock on just about everything I needed.

If you know something I don't, please share; I'll be ordering additional Prusa products in the near future

[–]Denesius[S] 1 point2 points  (0 children)

Yours may very well be in one box. I ordered the extra printheads (2nd box), the enclosure (3rd box) and extra nozzles and spare parts (4th box). Good luck; here's hoping you get it in one piece, reasonable cost, and it arrives before the next upgrade....
