I started a buildup thread of our 5x10 gantry on my favorite forum and will work on transfering it to here as I feel up to it, but I thought you all might like to see it.
I cant get the DTHC to come online. I can turn the Torch on manually. When I push the test button,the LEDs for UP and ARC OK for three series, then it changes to DOWN and ARC OK for another 3 and repeats.. Any ideas?
That is correct. If you see in the manual you will see the tip volts reading higher than the tip volts in test mode on the mach 3 screen and down will blick...then it will be lower then up will blick. Meanwhile Arc OK and DTHC online will be lit.
Thats the problem, they do not follow the sequence in the manual. I get NO DTHC online. I get NO volt reading at all in the test mode and the lights do not follow the described sequence. But I can manually turn the torch on and when I test ARC ok I get the LED to light.
Something is not hooked up right. You have only a DB25 and DB9 hooked to the PC right? You have your ethernet hooked to the control box and to the PWM box? FOR DTHC to be online it needs to see it in the white control box through the DBXX cord (not sure if its the 9 or the 25).
Typical diagnostics is to disconnect pieces starting at the end (PWM box) and move backwards to see where the issue is. Chances are the DB25 isnt plugged in all the way.
