Y-Axis

[JozB]

Hi Everyone, I am new to this site.

I am from Bronkhorstspruit, South Africa (Yes; it is on Google maps!)

I have my CNC machine since 2008 but now I have a strange phenomenon.

I have an E-Z router running Mach 3 and this is my problem of late. During the cut the Y-axis will all of a sudden go for a “Walk-about” in its own direction.

When I stop the machine and Reference All Home, the Z and X axis reference fine BUT the Y axis move away from the home position. Instead of coming back to the left rear position it is simply moving away down the Y axis.

I replaced the 25-pin parallel cable, replaced the Y axis limit switch, replaced the connector blocks on both the Y axis stepper motors, to no avail. I contacted E Z Router in Texas but they do not seem to have an answer for me.

Anyone have a suggestion of what may be the problem.

Thanks in advance.

Does this machine have limit switches?

I think the problem is solved, I have run the machine for 2 hours now without the problem occurring again.

I tightened all the screws of the Y- axis terminal block on the BOB, also followed the directional wires to the stepper motors and re-tightened that as well. For good measure I replaced the Gecko drive and installed another extractor fan in case of possible overheating.

Thanks for all your assistance.
