jamscal's 5x10 Gantry Build

[jamscal]

Still no dthc.

Under config. It says no power supply detected under Power Supply and last error history was Current over limit.

Everything is plugged in and on.

Thanks,

James

Verify the black box is set to 50-1 division. Also verify the yellow cable is plugged in from black box to controller not PC. Also verify the 9 pin cable from PC to control box.

[jamscal]

Thanks! I had the 9 pin plugged into the back of the computer but that was loose in the case for some reason

....used the other 9 pin and it came online.

Says dthc online.

Green light is blinking. Torch Volts reads now.

Seems to work but torch amps reads zero???

Verify MIC01 cable plugged into the back of the plasma cutter and two end in the correct place in the PWM box.

I'll double (triple?) check or take pics Monday.

Today's problem:

Went to the shop to fill up the water table and mess around with it.

went to zero x and y to cut a part.

Hit reference x by mistake and one motor took off and the other didn't! Hit stop but tweaked it based on measurement.

Turned everything off, pushed the gantry even (as possible) and restarted. It jogged fine but sure don't want to hit ref x again.

Also, the side that didn't take off had a set screw loose on the big gear. I tightened it. Didn't remember it being like that but could have overlooked it.

Tried to load a part that worked fine yesterday and there was an error, wouldn't run. Also the up light on the dthc was red (just twice during all this).

Not sure if any of the above is interrelated..

The 25 pin connector into the box was sagging when it happened (I had the adapter in there.) too. Replaced and tightened with replacement cord. Again not sure if related...


I'm going to loosen the bolts of the gantry, line it up and retighten.

Try it with the new cord when it arrives.

[jamscal]

Everything is back to normal today..don't know how exactly but it is. Cut parts throughout the day.

Still no torch amps. Not too worried.

Here is a pic of the box. We did make it 50-1 inside.

Another thought: the powermax45 didn't come with a machine torch originally. I think I read somewhere that that might make a difference.



Otherwise everything is tight and running right.

It could be that the divided tip volts wire cable was never installed into that unit. Give Hypertherm's tech a quick call.

[jamscal]

I'll call if necessary. Don't plan on needing to change amps on the fly, but who knows.

I need to know a little more about the dthc settings.

Torch is diving after the pierce...mostly recovering but sometimes not.

Should I set the delay time or tip saver and do I have to set it for every tool.

Cut some 3/8" today and it was nicer than I expected. This is fresh off the table with no grinding:



Getting a lot of splash when I cut near the side. I'm glad I went with the caulk. Now I'm going to make some sort of splash shield to ride on the gantry that prevents 'direct hits' to the trucks .

THC delay needs to be longer than the pierce time plus the time it takes to egt to cut height plus the time it takes to actually move. Never initially go by the Hypertherm book for cut height. Always go at least .020 higher as tip volts will set cut height once THC delay is gone and THC takes over. I cannot stress that enough to folks
