Newbie needs CNC advice

[JAZZCNC]

The Cheap Chinese machines are waste of money and will give you more trouble than worth. They won't do what you want correctly or very well. Unfortunately I can't offer any alternative at the price level your looking.

Regards running on i-mac then you'll struggle. Best option is to buy cheap second hand PC, you'll pick one up for £50.

Cheers thanks Jazz

Hope this doesn't confuse things but I'm Mr Jacks lol

Would the laptop be ok, if we disable the power saving functions & had it plugged into the mains rather than battery power?

Price isn't set in stone Ideally looking to spend £500 to £1000, certainly not thousands though.

Hi. I know someone who uses a laptop for his cnc control so you may be ok if you turn off power save etc.but an old pc is better if you are running Xp,Windows 7 using the parallel cable. Ethernet breakout boards are outside your price band. As to which machine,big question. For fine detail you need good signals,and that means Ethernet smooth stepper boards which would give you better cutting detail on Smaller items like your pens.but Ethernet boards cost a lot more and in some cases also need a breakout board also.you will need the software motors etc. Your best bet is to look on eBay for a up and running machine with cnc etc. Two sieg sx2 cnc mini mills have been sold on eBay this past week for sub 600 pounds.

THANKS for the info John,
Did a quick google & Ebay search foer Ethernet CNC & it just came up with boards etc, so are these upgrades for a the parallel port machines? I was origional looking at this https://www.amazon.co.uk/HPcutter-Ma...2BMachine&th=1

Do you have any links to suitable/quality new machines, I realise It looks like we'll have be paying more than our origional budget (story of my life) but if these Ethernet boards etc are upgrades? I am hoping to start off with a quality Machine then add upgrades as & when needed as our CNC experiance grows!

The laptop is a problem if you are using the parallel port to control the CNC. For USB or ethernet controllers it is fine.

hi. OK. to answer some of your questions. Ethernet boards use an Ethernet cable not the parallel cable and work better with lap tops due to the way the signal is pasted to the board. as you may know laptops are set up differently then desk top machines, battery saver being one of them, which will upset the internal clock of the laptop. and its this internal clock that the cnc works on. people use old desktops running windows xp or 7. because it allows the use of the parallel cable, windows 10 will not, but will run an Ethernet board. most people I think make their own cnc conversion, shop items in the uk are very expensive. the cheapest I machine I know of is the proxxon mini mill which as the motors etc fitted but you would still need to buy the boards to talk to the machine. Its not cheap this cnc stuff.

Keep in mind what jazz posted above. If you want to use the machine for a business, it is not reliable. If it's for hobby and to get into the cnc world, than it could be better than a LEGO cnc. I see on amazon that most customers are satisfied with the machine. I have no personal experience with these cheap Chinese CNCs.

It is possible to upgrade to usb or ethernet but not worth it, for such a cheap machine. You have the option, for example, to get the UC100 + UCCNC software and use your laptop instead of buying a desktop PC and a mach3 licence. But I cannot tell you more as I never used them.

Be aware that the machine you linked has only the demo version of mach3 software.

There is a proxxon mf70 Inc mill on eBay now for 375. So with a cheap breakout board for 38 pounds from cnc4u and demo programs to start with.you are up and running for 400 pounds or so.I had a mf70 and for light work it's a good machine for the money
