They quite often just have pilot hole but have you asked them if they can bore them out for you, don't forget grub screws

I have just checked http://www.beltingonline.com/20-toot...20-5m-15f-7776 there is an option for the boring and grub screw holes. bit expensive thou , not hard to do.

I usually let them do it, its a bit of faffing about that i can do without for the sake of 3 or 4 quid, plus getting the grub screws as well :)

I found those at aliexpress, they are made from aluminum alloy come with 10mm bore and two screw holes.
I am going to use 1/1 ratio for X Y and 1.5/1 for Z , are those any good, anyone has experience with those?
Any suggestions about the belts?

Just notice that they seems to be the same with those Wallace suggest ,with no shipping cost...

These are compatible with Mach 3 and Linuxcnc but if you want to use Mach 3 it has restrictions no later than Windows 7 and 32bit only. Step generation is done by the processor on the PC performance can be very acceptable and it's a very cheap place to start it also has proven reliability people have run setup's like this for over a decade now with no issues. You will need an old pc pentium 4's work well and have parallel ports built in generally.

Other options normally are step generators and cost a lot more but performance will be better, one to watch is boards are generally Mach 3 or Linuxcnc not both. Mach has a lot of USB controllers which work via plugins linuxcnc has no usb options at all! USB is crap TBH and should be avoided. Not sure what other options for Mach 3, Linuxcnc everyone gets a Mesa card be it PCI or Ethernet.

You could also buy a ddscv see Boran's excellent thread, for the price not a bad choice at all and I was tempted.

If you want dual homing on the Y axis (so it squares the gantry automatically) mach 3 or linuxcnc is your choice can be accomplished with a cheap breakout board. In the end this is what swumg it for me to stick with linuxcnc rather than get the standalone controller.

If you are spending all that much on the motors and drivers, then I would go for a proper motion controller not a Parallel port BOB.
