I then restarted the system used simple Home to home the machine after jogging the axis including z the brake release...

Update on the z axis problem. I replaced all cables power and feedback re wired the brake and sent the z axis motor back to Teknik to be checked. Re installed the motor Auto tune the z Everything went perfect. Powered up Acorn jogged to home position set home and then tried to move z and it dropped ...

Hi Keith. I think that a good idea i just order one as well as a new set of cables. If it did it every time i would blame my wiring but its random and once homed runs a program with no errors. I am still working on the steps per inch problem. It also seems like there is a lag between the Clear Path ...

here is a picture of the Panel and how it is wired. there is a on off switch wired behind the disconnect press on Button it powers up the Acorn Board and second 23 V power supply. Turn on cnc 12 hit reset to enable the drives and VFD home machine and go. All work well except for random z axis drop.

Machine running tool change simulation

Are you performing actions that require the brake to be cycled on/off during machining? If not and you are simply looking to prevent Z drop during off times, you can energize the brake with the OkFault output or connect it to the 24v power to come on with the system Hi Gary thanks for taking a look...

Machine running simulating tool change cycle. The random Z axis drop just started happening.

Thanks all for taking a look. The brake is released vis z axis brake release on out put 3. This Z axis drop is random Sometimes I power up home normally and then run a program and all is well. But the error can be made to happen after a power down after a change has been made to the Wizard. On drive...

Drive powers up normally when jogged brake release and z axis moves. But when Homing is started it randomly fails and drops hitting reset twice enables the drive and it can then be homed. The drive will also lose control of the z axis randomly when a cycle start is commanded at the beginning of a pr...
