Well, we finally found the problem. Turns out the prior owner of the machine altered the wiring of the head a bit and bypassed some of the safety circuits.

So the motor overload (MOL) was tripped...

The spindle does turn and the oil is flowing. I loosened a fitting and oil is continuously flowing. I ohm'ed out the float sensor on the oil reservoir and it is working properly (the sensor is...

I am convinced my problem lies before the drives come into play. I do not hear the relay close (or whatever the audible click heard when power is enabled to the drives). Therefore, something about...

Hello All,

This morning, my EZTRAK booted normally as it always does and i hit HOME as usual.
Bam, Alarm, hit any key to continue. Hmm, that is weird... So i hit any key and try again but get...

Thanks for all the input above. After swapping servo cards and seeing the abnormal behavior remain on the Y axis, I eliminated the boards as the source.

I use MasterCam 9.1 to create G code for my EzTrak. It has two post processors for EZTRAK. One creates .pgm files, the other creates G code. They both seem to work fine, but I like the G code post...

Mark,

GOT IT!!

Thanks for your help. It was the left arrow key in run mode that I was missing. I wish this was in the manual (maybe I don't have a complete manual).
Anyway, all my programs...

Mark,

Thanks for the reply. My problem is getting the EZ-Trak to recognize that I am trying to load G code, and not an EZ-Trak program. The only option of loading a program is an *.pgm file. I...

Hello All,

We recently purchased a Bridgeport EZ Trak SX II. The machine works great and we are very happy. The manual states that G code can be loaded into the controller and run. I have been...
