Good morning, all.
Not sure if this is the right place to post, or if someone can point me in the right direction.
When my CNC machine is turned off, I can normally push the gantry around by one hand quite easily if I need to move it.
Yesterday when I tried to push the gantry (no power on) it was very difficult and required two hands and a bit of force.
I started up the CNC this morning and can jog short spurts in the Y direction, but if I hold the jog button it will travel about 4-5 inches and stop, needing a reset.
The machine has been working fine for over 5 years. I have not adjusted anything recently.
There seems to be way more resistance to movement in the Y direction than there should be.
X and Z movement is fine.
There are two motors on the gantry, one at each side.
Advice?
Thanks
