Unable to get G3 to home X Axis

[rfontani]

This a router that I am upgrading with a Masso G3 . The router has 2 motors on X Axis, driving ball screw shafts.

The shafts are connected together at the far end by timing belt. I have the Masso up & running for the most part,

it jogs all axis just fine. When I do cntrl alt home it does Z axis fine then does Y axis fine but X does nt work,

It just chatters. so I checked out the motors by switching the wires. I swapped X & A and motors & Gecko G540

are working fine. Jogging works fine. when I home it the A motor does not turn at all. I cannot find the trouble.

Could it be software? I reloaded the software the they sent me, no help !!!!

Please understand This machine will JOG perfectly in all directions & all axis.

I have it calibrated to .001" in an 8" span on X & Y, --- Z needs a little more adjusting.

I have uploaded the setting file check it out. The motors are working perfectly jogging,

the motors on Z & Y also work perfectly when homing but the A motor does not move

when it tries to home X --- but X motor does try to turn. A axis is not being told to

move . If its runs fine while jogging there is some thing wrong in software .

I've been working on cnc routers for about 10 yrs. Ive seen all the mistakes.

Hi rfontani

My apologies, My previous reply was wrong as I miss read the settings file.

I now realize that you have the A & X axis software slaved but you are missing the A axis homing sensor.
The A axis sensor is used for auto squaring of the axis and is a necessary part of the homing process.

The A axis is also not ticked in the homing sequence 3 with the X axis. It should be showing up on the homing screen with a tick but grayed out.

When you home the machine the A & X seperate and once move towards their sensors.
once the sensor is triggered the axis stops moving and then the X & A axis will back off together.
Without the A axis sensor it cannot do this.
