Thread: Reducing costs
Direct driveHappy are they who dream dreams and are willing to pay the price to see them come true.
For the price of the laser cutting/templates you could buy all the steel needed to build the frame and have 50X stronger machine. Bolt it together if you cant weld or have someone weld it for you.
Also can I just say you are going about this all wrong regards the electronics. Roy's stuff is ok but it's more suited to smaller machines like Mills not routers. This is because the drives are low voltage with a Max of 40Vdc I believe. Routers run much higher feed rates than mills so we need more speed from the motors and steppers get there speed from volts. 40V max drives will be restrictive to a router machine unless you use a high pitch ball or lead screw and this will lower resolution so your getting a unbalanced machine.
Trying to cut costs on electronics is asking for trouble and never ends well.!!
Or you could make one from a piece of box section.

Forgive my ignorance as I am new to cnc ,well , that is ithas taken me 6 years toget tothe pointwere I have bough nearly all the stuff I need.
And I was unaware that geting a steel carcase made up to order was going to cost me less than £145 , which is what it is costing me to get the cad files laser cut and laminating them to the 18mm birch ply.
But I am already committed to the system 4 set as that was here yesterday, and quite frankly was more than I could really afford, so I'm stuck with that, besides the machime won't be cuting anything harder than 18mm ply and mostly foam and wax patterns for castings in resin , aluminium, brass and hopefully in time bronze!Happy are they who dream dreams and are willing to pay the price to see them come true.
To be honest with myself I'm building the bloody machine to prove I can.Happy are they who dream dreams and are willing to pay the price to see them come true.
For what the OP wants System 4 is a great system to use.
usual disclaimer only a very satisfied user.
