    Hi,

    I've built a 4x4 router belt drive router table for cutting foam board. I use a gecko g540, mach3.
    My X axis has two motors, with A being a slave of X.
    I have 2 x limit switches each end of the X, Y, Z

    Looking at the whole table head on as if the X axis comes towards and goes away from you I assume that the norm is to have the table home to the back left hand corner. To me looking down the table thats the far lefthand back corner. is that the normal homing area?

    Does anyone have screen grabs to set up the homing for this 4 axis table, I followed the Mach3 instructions but we keep on having problems with something and i'd like to eliminate our Mach3 setup incase its a wiring issue.

    Any links or direct screen images welcome.

    Thanks

  2. On my 6040 I have home as the front left hand side. +Y is to the rear of the machine, +X to the right and +Z to the top.
    No home/limit switches as yet.

    I home to front left side (Your X+, Y-, Z-)

  4. Home can be anywhere you want it, provided you set the offsets right.

    Some people will home at a front corner to get easy access to the spindle, while some will home at the rear to improve loading/unloading. You could even home in the middle of the table if you really wanted to, it's just a case of setting the home offset in Mach.

    Hi and If that`s the case, how would you set mach3 with appropriate directions of travel - I`m quite a novice and at one point I even had my cutting file upside down and off the defined table

    You can't change the directions of travel. Mach3 uses the Cartesian Coordinate System, and each axis has to move a specific direction relative to the others.

    Now, you can have the machine home to anyplace you want. to do that, use the Home Offset settings and use the Home Negative option to make sure the machine travels in the correct direction to find the switches.
    I have my X axis home offset set to 45, and home to the positive X direction. So my home switch is at X = 45, and machine zero is at the opposite end from the switch.
