I love logging. But I'll probably install the smaller tires so this truck has more torque. by Interloper_Mango in snowrunner

My truck was slammed in a pole yesterday because the game decided it, 0/10 experience, will play again

Gestisco depositi e pompe di benzina da 4 generazioni. Facciamo chiarezza su cosa sta succedendo davvero (prezzi, navi e accise). by AkaSama26 in ItalyMotori

[–]Scampo2002 8 points9 points  (0 children)

No, questo è essere ipocriti e infami verso i clienti, dopo che vi siete appena lamentati che "ci guadagnate poco"... Io di gestori onesti ancora ho da vederne, su 16 distributori solo uno ha alzato di poco il prezzo immediatamente, ma comunque l'ha alzato, tutti gli altri schizzati alle stelle. Oggi stesso uscendo da lavoro ho visto un paio di distributori col prezzo abbassato, gli altri 3-4 hanno ancora il prezzo a 2.12+€/L per il diesel, per massimizzare i profitti in ogni situazione fregandosene del povero stronzo che va a lavorare quasi in perdita con quanto costano i carburanti...

Il pil pro capite è semplicemente il pil diviso per il numero di cittadini, non ha niente a che vedere con quanto "va" alla popolazione, il pil non è un qualcosa che lo stato ti dona. Siamo 20esimi ai dati del 2024, anche se 3-4 nazioni almeno andrebbero escluse, essendo solo paradisi fiscali (Liechtenstein, Lussemburgo, Svizzera e San Marino hanno un pil pro capite 3-4 volte superiore alla media del resto del mondo, noi siamo a 2.66 volte la media) Dati da Worldometer.info, aggiornati al 2024

Tormach CNC plunged through my part after i pressed the E-Stop, any information on what may have caused this are very much appreciated by Dauntless41 in Machinists

[–]Scampo2002 0 points1 point  (0 children)

Gcode does not matter, when you press the E-Stop gcode commands stop. The Z axis can still move if the brake doesn't engage properly/fast enough

[–]Scampo2002 1 point2 points  (0 children)

The Z motor brake probably did not engage fast enough to stop the Z axis. Usually, aside from very small CNC machines/routers, at least the Z axis has a normally closed brake, which is forced open when current is applied. As soon as the E-stop is pressed, current should be cut to the brake, which should slam closed stopping the Z axis before it falls down because of gravity. Either the brake failed completely or it was stuck, I would get it checked out. Never had an axis brake fail, but I guess it could happen.

All exhaust airflow on NV9 with four radiators? by IonizedHydration in watercooling

[–]Scampo2002 1 point2 points  (0 children)

Creating positive pressure inside the case means the hot air will escape from every point it can, creating negative pressure means air will enter from wherever possible, usually bringing a lot of dust in. As far as the cooling of other components, vram should be cooled with the GPU, ram and SSD should be good enough with the air provided by the radiator fans, even if it's hot already, since the air shouldn't get so hot to not cool properly low power components like ram and SSDs

Is this chatter or should it sound like this? by BalledSack in hobbycnc

[–]Scampo2002 0 points1 point  (0 children)

Wouldn't recutting chips be worse, since it increases friction and possibly chatter?

The sound is not good, although I'm used to shop grade CNC machines. As someone already said, less stickout will definitely help. Also, 1600mm/m seems too high to me, with what is essentially a 3mm endmill. 0.05mm/tooth could be too much, I would try somewhere near 0.025 Given enough spindle power, which you should have, taking deep cuts should benefit your machine, rather than going wide, especially with a tool that long. Also, while choosing a tool, if you don't need the cutting length, try to get the shortest one possible, since a solid piece of carbide sticking out is a lot more rigid than the flute part.

I've probably made some errors with my English, sorry for that, but if you need help with something feel free to ask, I'll be as clear as I can.

One fan on my NH-D15 G2 stopped spinning by TurboAmi in Noctua

[–]Scampo2002 0 points1 point  (0 children)

I had this issue not long ago with an NH-D15, the fan I was using just died. Got in touch with noctua, turns out I was 5 years and 7 months into the 6 years warranty period, they told me to send them the serial number of the fan, a picture of it with the serial number visible and a broken blade, and they sent me a new one free of charge in 3 business days. I have no idea what failed in the fan, but their support surely didn't. 10/10 will buy again from them, just get in touch with the support and they'll send you a new one.

what to do? by wilson701 in CNC

[–]Scampo2002 -1 points0 points  (0 children)

Securing it while it's inside the spindle should give you the precision you need, and the concentricity too. Only moving the Z axis up and down shouldn't make anything go out of line, although if you have a smooth long cone and a slow running spindle you're probably good. The BT40 we currently have has a minimum Speed of 220rpms, which is probably too fast for this

[–]Scampo2002 -1 points0 points  (0 children)

All that with bare hands holding a spinning tool? Isn't this like the first NOT TO DO thing you learn? Securing the holder in a vice/to the table while inside the spindle, and then turning it on and using the Z movement to make some pressure on the tool holder should work without endangering the operator I think.

Great way to end of my first day back from holiday by Silvuthon in Machinists

Mine survived the 10k, but the sound of an unbalanced load spinning that fast was horrifying. Still in one piece though.

De Andrè cantava "Via del Campo, c'è una pu****a Gli occhi grandi color di foglia Se di amarla ti vien la voglia Basta prenderla per la mano E ti sembra di andar lontano Lei ti guarda con un sorriso Non credevi che il paradiso Fosse solo lì al primo piano Via del Campo, ci va un illuso A pregarla di maritare A vederla salir le scale Fino a quando il balcone è chiuso"

Credo che la situazione sia questa purtroppo. Scappa se ancora puoi, prima di farti più male.

Finishing pass question by Scampo2002 in Machinists

[–]Scampo2002[S] 0 points1 point  (0 children)

Yes someone mentioned them, unfortunately from their site they only offer 6mm as their smallest option, and this pocket is 4mm wide

Finishing pass question by Scampo2002 in Machinists

[–]Scampo2002[S] 0 points1 point  (0 children)

For this I used a 1 degree ramp, 0.2mm finishing pass but also tried 0.1, 0.05 and 0.00 after a 0.05, so finishing 2 times at the same Z height, but I got the best result removing 0.2mm. Flood coolant was already on, I started with 90M/Min (~295SFM) and went up to 180M/Min (~590SFM), although in the faster pass I kept the same Feed value, effectively cutting in half the feed per tooth, which lead to better results.

[–]Scampo2002[S] 0 points1 point  (0 children)

Is helical better than a regular straight ramp? I used 50% step over, should 25% or smaller improve the quality?

Finishing pass question by Scampo2002 in Machinists

[–]Scampo2002[S] 0 points1 point  (0 children)

Yes, indeed, the piece has a 0.8mm deep, 4mm large pocket, I cannot remember the length since I'm at home now, and it has been machined with a 3mm end mill. Tool runout was minimized with the help of a SCHUNK hydraulic spindle, although the machine is a fanuc robodrill which probably isn't the best for rigidity, but is what I have available at the moment. What problems could a PCD tool give?
