X Axis is not responding to Homing request

kleslietx

Hello all,

First of all thank you so much for this forum.

My issue is I had just finished setting up a Voron 2.4 frame with the Duet 6HC + 3HC expansion board. I was in the final stages of tuning and it seems my X-Axis stopped responding.

My understanding is if I run this code it should move the tool head in a square pattern.
G91 ; relative mode
G1 H1 X10 ; move the X motor forward 10mm
G1 H1 Y10 ; move the Y motor forward 10mm
G1 H1 X-10 ; move the X motor back 10mm
G1 H1 Y-10 ; move the Y motor back 10mm
G90 ; back to absolute mode

The tool head movement is only through the Y axis.

Walking through the CoreXY setup everything works. When I execute "G1 H2 X10 F3000" the tool head moves diagonally in the +X +Y . Also, using this g-code "G1 H2 Y10 F3000" the tool head moves +X &-Y.

Also, if I use the web interface to home the X axis it appears that it homes but there isn't any movement. If I forcibly move the axis to its home position and use the controls to move the x axis the tool head moves fine.

This occurred only after I walked through the CoreXY configuration. I'm sure I've done something inadvertently but cannot seem to find it. Please help. I've posted my config.g file, homing files and M122.

solved....it was as bad limit switch and a lose wire on the B-motor. Once I replaced the both the machine moved as expected.
