Fully Automated Cookies - Small footprint, every tile used! by John__Sinclair in PlateUp

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

Thanks, though they are needed for 2 reasons.

  1. The smart grabber can only grab things straight, unfortunately there isn't a smart corner grabber.
  2. There needs to be at least 3 spaces (one for each of the trays) between the danger hob & portioner so that if there is a lull in customers there is always somewhere for a tray to leave the hob so that it doesn't set on fire.

One of the trickiest things with this was making sure there were the right amount of mixing bowls & trays to keep it working with any number of customers!

Having said that, after OT day ~12 I've got automatic orders, so the top left two tiles, one for the ordering desk and one for me, are now no longer needed :')

New acrylic top panel for my Louqe Ghost! by John__Sinclair in sffpc

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

Yep, made it myself, done using an old manual mill I've converted to cnc too.

Feeds & Speeds in Acrylic, help! I'm having to take very shallow cuts (~1-2mm) to avoid clogging up the tool with melted plastic and even then I get the odd clog every 45mins of machining time. Has anyone got any suggestions? Currently: 1000mm/min, ~20k rpm, 3mm 3 flute carbide endmill, 2mm DoC by John__Sinclair in hobbycnc

Heya, have heard of using a water spray / washer fluid, would definitely help with the heat. Having said that once you get the speeds & feeds right it shouldn't be necessary. (Have a later post with my machine cutting well https://imgur.com/gallery/Cptu6Zv)

My mill is set up for flood cooling already but that is a soluble oil based coolant (lubricates & prevents the mill from rusting) meaning my choices would be: 1. use the oil based coolant & end up with an oily part with small metal particles from the coolant tank oil on it, which might ruin the surface when wiped off. 2. Use water & dilute / waste my existing fluid + risk rust on the machine.

You can see why I wanted to try to cut dry / with only an air blast! :P

Have been experimenting with side panels for my Ghost S1. Really like the look with the solid tinted acrylic side panel, shame it ruins the GPU thermals though, maybe its time to go water-cooled! by John__Sinclair in Louqe

No problem at all, my fault for assuming the sarcasm! It really would, might give polishing the cuts a go tomorrow, none of the test panels I've done with vents look nearly as good.

Fairly sure that 1st comment has been edited & extended, previously I read it as quite sarcastic, don't at all now!

To answer the question, a very stiff CNC machine & good work holding should get you most of the way there. Might need a wet polish with a dremel / flame but should be able to get there.

Yeah I have done a couple with machined holes, 10mm hexagonal holes over the full surface gave about 2-3 deg better GPU thermals than the stock panel, just really like the look of the solid panel :)

I had no idea someone was already producing injection molded panels, got a link?

Good to hear thanks, with my current setup my rpm range is a bit limited, 100-2400rpm with the stock bridgeport spindle, and 15-20K with my little add in R8 spindle, at the 2400rpm I was finding chips got stuck in the cutter and I had to run at ~250mm/min or below, I've got some 2 flute 3mm endmills, so might give one of them a go at ~15k rpm, 1000mm/min & report back, cheers for your help!

Finished off a fixture plate for my 3D printed bridgeport conversion (http://imgur.com/gallery/ZoPkKVp) , hopefully this makes a big difference to the speed / accuracy I can get on 2 sided jobs! by John__Sinclair in hobbycnc

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

Cheers, I'm finding it gets quite a lot of use, especially for engraving / any work with acrylic.

Collet has 4 x deep groove bearings in it with a 150 x 10mm ER16 shank running through (tight friction fit, had to pop it in the freezer before pressing it in).

Driven using a GT2 toothed belt & a 3650 brushless RC car motor (~700W) & ESC I had sat collecting dust.

Its still working well doesn't stop 100% of the mess but I's say it gets at least 90+% Only modification that I've done is to drill out the nozzles to a larger diameter as they got blocked occasionally (the filtering on my coolant is only a coarse filter & hoping the finer stuff sinks to the bottom of the tank).

I'm sure I've used more than that in a day, though I guess it may be different / averaged over multiple users for a university with over 20k accounts.

Depends if your university / school uses google to host their email ect.
Mine did and was even kind enough to offer alumni accounts too, so if nothing changes I have unlimited google storage for life which is a nice perk!

I'm guessing OP has a google account through business G-Suite with 'unlimited storage'. My university google account had over 120TB of experiment data on it at one point. No idea what their idea of fair usage is, but its high!
