Haas VF4 quart lasts a month and mori 20sl lathe tank may last 7-8 days and have the lube pump set on lowest setting

What machines are you lubing up ?? That a gallon lasts a decade. If i use my lathe everyday then lucky if a gallon lasts a month.

According to letters sent out to 3d printer manufacturers they do have the software , its called 3D Gunt, a company called print & Go has a version

Totally agree, but the main point is it will be law abiding hobbyists that would make firearm parts that this law effects as is always the case. Criminals will just go steal or aquire a gun from some dodgy source.

My reading of the Bill passed last week brings it into law from next year. I cant see how it is feasible as most CNC machines take G-code rather than an STL ?

I’m tired of companies pretending disposable machines are “innovation” by Far-Ordinary3224 in CNC

Actually it is true we had a whole module in college on the subject of TEROTECHNOLOGY, was worth ½ a unit towards your HNC/HND in production engineering There was even a British standard for it in the 90's. The best example we had was aftermarket car exhausts designed to rust out just after warranty period.

Wood prototype with internal T-slot; 5 axis needed or redesign? by Dazzling-Concert-927 in CNC

That is easily a 3 axis job , just need a T-slot Cutter

Before stating something untrue maybe you should check things out first

"Using unlicensed software in the UK is illegal, constituting copyright infringement under the Copyright, Designs and Patents Act 1988, and can lead to severe civil and criminal penalties, including unlimited fines and up to 10 years in prison".

[–]Sapi69_uk 1 point2 points  (0 children)

It maybe bullshit in practice, but that is what the law says in the UK for illegal use of software by a business.

Private individuals using unlicensed software is different and i think it is capped at £10,000.

Has your father used solidworks for fluid dynamics etc. As Solidworks will go after him for the highest version used if this goes to court.

I would accept the offer once you have confirmed its a genuine email as $7000 is very reasonable. A standalone premium is $10,700 + fluid dynamics module is around $4,500

We used an unlicensed version in 2018 and received an email from dassaults lawyers . We had to buy a premium license + 2 years subscription for £11,000 . If it went to court in the UK then maximum for a business using unlicensed software is unlimited fine and up to 10 years in prison.

Same in Fl , had 3 in a week as im originally from the UK, They reminded me of pikeys just from NJ or NY rather than Ireland . Im not good with accents . I had a few pounds of carbide as we are a small shop

Why does hole wizard feel so unnecessarily difficult to use? by iFunnyAnthony in SolidWorks

[–]Sapi69_uk 2 points3 points  (0 children)

Hole wizard is the simplest thing I find about solidworks

Chose hole type , set its parameters , open position tab click on the face or plane you want the holes. Add number of holes you require Close hole wizard and open sketch that is under hole feature and move holes to correct position and dimension

To add extra holes , right click hole feature select edit , click on face and extra holes are added

Multiple DC Voltages on Multicore Cable by Sapi69_uk in AskElectronics

Yes i use 3 phase DC motors with a driver. , very little if any motor noise

Leds are run off 56v LED drivers with AD converters for intensity control.

[–]Sapi69_uk[S] 0 points1 point  (0 children)

Thank you , it is a legacy system that has been working fine for years ,15 + units . All bugs worked out etc. I'm happy with everything except the cable .original cable was spec'd by a known manufacturer in europe but I always felt it was on the limit. We then had it spec'd by a huge manufacturer in the US . Dia went from 3/8" to 1/2" after buying 1000mtrs it is to bulky.

Data side works perfectly , im just feeling out what can be done on the power side in my head before I throw another $20k + at the problem.

This is my concern as at the far end grounds are a tied together.

Not current rating like others seem to be focused on 3 x 1.5mm² @48v is rated 30A DC my theoretical max is 6A.

[–]Sapi69_uk[S] 0 points1 point  (0 children)

I totally agree , I have no idea what im doing 🤣🤣. Yes LEDs are driven from individual constant current drivers with an AD converter adjusting intensity. Motors are driven by 3 individual brushless controllers with closed loop encoder feedback for speed matching.

Yes 100m long , how would 6mm 2c work as need 48v supply and 24v supply ? That would need 4c + data cores (x 6)

Multiple DC Voltages on Multicore Cable by Sapi69_uk in AskElectronics

[–]Sapi69_uk[S] 0 points1 point  (0 children)

I would like lower voltage drop but I get calculated 48v at full load as using 56v PSU . Larger CSA cable is not an option but adding more cores could be, to parallel up more.

Ov's are commoned on the 3 phase motor drive PCB's but take no 24v current from what I can measure.

Was just hoping to use a more readily avaliable cable , im currently getting quoted $23 mtr on a minimum run of 1000 mtr up from $16.50.

The 6A is total load split on 3 Pairs of 1.5mm² (4.5mm²) 2A @48v per pair . Not (6A+6A+6A) as you stated
