Homing Failure

Post by Exhibitology » Wed Jul 26, 2017 5:01 pm

Greetings,

We are putting the finishing touches on an All-in-one installation using CNC11.

It is going well but I can only home the Y axis. It trips the home switch and back off as it should.

But with the X and Z, I get the following sequence.

302 Moving...
327 Fault: job cancelled
411 X axis (1) full power without motion
SV STALL ERROR Reported by CNC11!!!

The axis moves to the switch but the machine shuts down as soon as the switch is tripped.

All the axis use the same NC limit switches. They light up as they should in the I/O screen -- 1, 3, and 6.

Your help is appreciated.

Rich

Did you have to set Direction Reversal for any of the axes? If so, did you remember to swap the limit switch connections and definitions for those axes?

For example, without direction reversal, the X- limit/home switch connects to INP1, and the X+ limit/home switch connects to INP2. On the Machine Configuration screen you would have 1, 2, 1, 2.

If you have to set direction reversal for X in order to account for motor mounting direction, then you would swap the wires (minus switch to INP2, plus switch to INP1) and you would swap the definitions on the Machine Configuration screen: 2, 1, 2, 1.

Do you have a full set of six switches (plus and minus for each axis)?

In which direction are you homing the axes (default is X-, Y+, Z+)?

Without attempting to home, can you use Slow, Continuous jog mode to move all axes in both directions without error?

If you trip any one limit switch, can you still use Slow, Continuous jog mode to move away from the tripped switch without error?

Solved. Just needed a night of rest and TB137.

How did you fix this issue. A nights sleep isn't helping me and I have the same issues but only on the Z axis. This is the only axis that is not reversed. I can jog all axes smoothly without issue and all other functions work as they should. This is the only problem so far. What is TB137

Thanks in advance
