Electronics for Hobby-Line 6045 from Sorotec

[hardenum]

What electronics have you purchased so far.?

None, only the frame and the spindle. I though I'd ask first, since I have no experience and I'd rather pay more for quality electronics and have it last a few years then have something cheap that will only work for a few months.

My total budget for the whole electronics shebang including a spindle drive is 1000EUR.

Ok well, that will get you a nice setup.

Regards the controller then if you don't need more than 6 Inputs and 8 Outputs, which for a typical router that doesn't use tool changing spindle is more than enough. Then I'd look at the AXBB controller as it's a neat little package that doesn't require a BOB. It's got all you need from a controller 400Khz frequency and 24vdc I/O and 0-10V Analog Output for spindle control.

The UC300ETH and UB1 is also a very nice combo but it's expensive and if you don't need all the I/O then it's a waste of money which could be better spent on other things like Closed-loop steppers. Which brings me nicely onto steppers.!

The price of Closed-loop stepper systems have dropped to the point it's not worth buying a standard stepper system if you can afford the little extra.
I've fitted many closed-loop systems now and they are superior in performance and more reliable than a standard stepper system.
You'll see many Chinese versions along with Leadshine who are most prominent, I've used most of the main ones you'll find and I see no difference in performance from the Leadshine over the others. Now I mostly fit Lichuan and buy direct from Lichuan these days.

You'll buy these a lot cheaper if get from China. Don't be afraid to buy from China because you can save a lot of money, I've been buying from China for years without any problems and to be honest, I get better service than I do in the EU and a lot more respect.

Regards the PSU then look for drives with a Max voltage of at least 70Vdc and run them approximately 10% below this rating. For a good machine, you want to be running the motors above 50Vdc to get higher RPM with torque but you'll see a lot of 50Vdc Max drives which you'll need to run at 40Vdc to be safe and this will lower the machine's performance.

Also, a lot of the current drives allow you to run them with AC or DC power, it doesn't really matter which you use the performance will be the same. However, AC is simpler as it doesn't require you rectify AC to DC using a bridge rectifier and Capacitors. It only requires a transformer with the correct AC output, the 10% allowance above still applies.

The best type of PSU for a CNC machine is an unregulated PSU, The most common type is toroidal PSU and if going DC is used with Bridge rectifier and capacitors to give the DC output required. They are simple things to build so don't be intimidated if going with DC power but AC does simplify things.

Regards the VFD then I cannot help other than to say any that meets the spindle spec will work. I only ever fit the Chinese spindles and Huanyang VFD's and don't ever have any problems.

Thou if it was me I wouldn't be paying a fortune for a brand name because the Cheap Chinese VFDs work perfectly well for the DIY environment and you could buy 4 VFDs for the price of a leading brand name.!!... Or 2 full sets of spindles and VFD's.!!!
