KLKS CNC BuildLog 02 – Buying Electronics
This buildlog I’ll talk about the electronics which will drive the CNC. I did a lot of searching on ebay as well as CNCZone and have found that the most common controllers use the Parallel port as a means of communication. I was hoping the controllers would use USB but alas to add USB support to the controllers directly = spending more money. Adding a parallel port however is a cheaper alternative.
I thought that a USB to Parallel converter would work but after reading on CNCZone they said it wouldn’t work, however the PCI Parallel adapters would. Seeing that my desktop did not come with a parallel port, I went out to Lowyat and picked one up from Sri Computers for RM22.
Back to the controllers, there are 2 types, the good ones, Geekodrive, HobbyCNC which are made in the USA and come highly recommended by users of CNCZone and the cheaply made in China ones which use the Toshiba TB6560 chips. The geeko and hobbycnc controllers (not including power supply and stepper motors) range from 60USD-200+USD.
Oh I also checked out if Jalan Pasar sold any, they did, they sold a 2A controller which costs like RM200. This is per axis….
After much searching and consideration I decided bite the bullet and buy the cheap China TB6560 Drives. I managed to find a seller which sold me a complete set (Driver/motors/power).
- 24V 14.6A Power supply RM165 (~53USD)
- 3 Axis Driver + NEMA23 1NM Stepper + 3 couplings RM544 (~170USD)
Mistake #1 : Bought 6.35mm coupling instead of 8mm couplings
