Installed the backguage, no motor movement, x r digital field on the screen shows movement, but no motor movement at all. I took the power supply out, 220V was selected, and the green field for the backguage is illuminated. I activated all the mircoswitches, each one stops the machine as they should. I checked the driver tab selections, they are all correct. I tried homing several times, it just times out after 5 min. I assume that the backguage stepper motors won’t do anything until it’s completed the homing process, same for the bend motors, so how can you test the stepper motors if you cannot home? any ideas?
power supply has no power - supposed to output 36V. Hooked up another 12V one I had on the shelf and everything works like it should.
Might have cooked it when on the wrong voltage.
I’m a bit confused about this. Why would someone replace a designed 36V power supply with a 12V version when the stepper motors require 36V DC? Additionally, the Titan 25 operates on 220 volts. It can only run on 120 volts if you use a step-up transformer, but even then, it’s still a 220-volt piece of equipment. Maybe I’m just not fully grasping the discussion.
Are you testing the 36v power supply with your meter on DC voltage?

The power supply was dead on arrival, obviously they don’t test the electronics/drivers/steppers before shipping them out.
The steppers will run on a wide range of voltages, not only 36v. They make less torque on lower voltage but they run enough to temporarily troubleshoot the system and discover the source of the problem. The power supply I temporarily jumpered in to troubleshoot the system was 120v input and output 12V. The factory power supply was dead on arrival. I ordered a new identical 36v power supply to replace the defective one, and I’ll be running parts again on Monday. I wish LS would have a little more quality control by testing the electronics package before it gets shipped out the door.

You got this.

We do test those - we have electronics testing stations for the backgauge electronics settup, the base machine drivers, the base machine motors, and a final batch of testing that runs the machine through an 18 ton bend.

ok, good to know. I installed the new power supply today and everything works like it should. I suppose the power supply could have been damaged during shipping from the vibrations and impacts.
