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.

For me I wanted to try both mach 3 and linuxcnc first before I locked myself into a vendor with an expensive controller purchase. I had a feeling you'd have to be a sadist to setup linuxcnc and I was right lol but I'm happy with linuxcnc (Never tried Mach in the end) so I've invested in a decent pci controller/step generator. I couldn't find a controller that was compatible with both Mach and Linuxcnc other than the PP BOB's.

These seems popular for Mach

Thanks both of you guys for taking the time to reply.
I have a pc with parallel port and Mach3 that I used to use with my previous CNC, so ni money to spent there for now.
Desertboy,I will find the Boran's thread and read it ,thanks for the input.
Cropwell ,I thought that parallel pots was superior that USB! Am I wrong?I am asking to learn,the only experience I have is with parallel ports.
