General Mach Discussion / limit switches and home switch help!!!

« on: April 01, 2013, 08:19:37 AM »

I have just built my first machine and with the help from all these forums its been great.
I now have my machine up and running but my issue is getting it to home out woithout destroying a switch.
I have my limit switches all on a daisy chain scenario and they work well except when homing.
I am starting to believe that its all to do with the pin assignment.

Should I have the pin assignment for the X home ,Y home and Z home be the same?

I have attached a couple of pics of my settings

If anyone can help it would be much appreciated.

Show"N"Tell ( Your Machines) / First CNC build becoming addictive.....

« on: March 31, 2013, 06:10:16 AM »

Although I drive up to 5 axis machines I cannot explain why I decided to build a small CNC , but anyway here is my first attempt.
It has now become a little bit of an addiction once it moves for the first time.
I have engraved a few silly bits and cut a few bits of MDF but nothing special other than knowing I amgoing down the right path.
The spindle needs a bit of attention as still setting up Mach3.

Attached is a couple of pics from design to reality.
Its all made from 12.mm Ally plate .
The table comes from a window frame manufacturer , just happens to have handy T-slots.
The spindle air cooled 24000 rpm.

All the electrics from http://www.homanndesigns.com/ with a big thankyou from Peter Homan for all his support.
Also a mate of mine Greg for patiently sorting the electrical side and strangely getting a slight addiction to the job as I too have.

Any comments or observations would be greatly appreciated.
many thanks for reading.

Many thanks Peter the only thing that has been throwing me is the ACM quoted ,and the fact it has AM on the terminal block.

General Mach Discussion / Mach 3 + Gecko G540 + Saj-8000 series invereter

« on: March 12, 2013, 08:00:01 PM »

This is my first post and wish I found this forum ages ago.
I am nearing the end of my first CnC build and am having a ball.
I have all the axis going well Mach 3 screaming with code and loving it , my next task is to get my spindle talking to Mach3 via a Gecko G540 drive unit.
Nows the problem I have an SAJ8000 series inverter and cannot for the life of me fathom out the the wiring instructions.
The Gecko G540 looks straight forward but at the invereter end I cannot get the signage on the terminal blocks to make any sense.
I have attached a pic of the terminal block at the inverter end can anyone please help before I create some smoke.

Thankyou for reading.
