General Mach Discussion / Laser Upgrade
« on: October 05, 2016, 10:35:48 PM »
Not sure if this is the right place to post this question but here goes.

Has anyone purchased one of these :-

I have a diy cnc router that has been great over the years I now want to put a small laser upgrade on, but I have questioned the seller as to what purpose the USB looking part of the package is for.
I would like to assume its to control the on/off side of things , wirelessly , but even the seller cannot tell me.

Can anyone help?

General Mach Discussion / Jogging off switches
« on: July 19, 2013, 01:17:54 AM »
Can any one help
I have built a small cnc router all good.
Home swithes have been wired in a daisy chain fashion and all work well.

Problem if I hit a stop either by jogging or during a program run I cannot get off the swith without shutting the motors down and manually winding off the switch.

Is there a setting in mach3 that allows me to jog off the switch without turning the thing off?

Many thanks

I wish to leave my machine running whilst away, is there a way of getting Mach3 to put the pc into an auto shutdown.

Can this be achieved?

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.

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.
