TMC3in1 FAQ / Re: My torch dives into the metal when I start cutting?
« Last post by RandyRay on July 14, 2017, 10:51:38 AM »
The first thing to do is make sure you check the box for Stop THC response when X-Y Velocity is less than N %.
 
At slow speeds, the tip voltage increases, and in order to reach the commanded tip volts, the torch will be lowered, sometimes causing a tip crash.  This is an Antidive feature to prevent the torch from diving due to slow velocities at the beginning of a cut, the end of a cut, and in corners.
The second thing to try is to increase your commanded tip volts by 5 to 20 volts higher than what the manual says.  If your tip does not crash or drag at the higher voltage setting, then there is a discrepancy between the manual and your system at these settings.  You can either remember to set higher than the manual calls for, or you can adjust your THC Offset volts to make a more permanent compensation.  You may need to go negative or positive with your compensation voltage in the THC Offset Voltage field.
 

Worn out consumables…
Normally you will see a decrease in cut quality when your consumables (tips) wear out.  However, if you really continue using a worn out tip, it may blow out or:
The Thermodyne manual stated that a cut height of 0.110” and a Tip Voltage of 126V was ideal.
Old Consumable: Commanded (and controlled to) Tip Volts 142V gave a height of 0.042”   
New Consumable: Commanded (and controlled to) Tip Volts 142V gave a height of 0.250”
New Consumable: Commanded (and controlled to) Tip Volts 130V gave a height of 0.115”

Please refer to the Vol 4 FAQ and Troubleshooting Guide under Q8 for photos of the settings in question.

TMC3in1 FAQ / Re: What does the THC ON/OFF button do on the main screen?
« Last post by RandyRay on July 14, 2017, 10:48:41 AM »
When OFF, you will cut your metal, but not adjust the Z height via THC.  When the THC button is ON, the Z axis can be adjusted via the TMC3in1 THC Up and THC Down signals.  If your button will not turn on, it is because you are in the Demo Mode of Mach3.  You must have a licensed version of Mach3 for this button to activate and THC to operate.

TMC3in1 FAQ / Re: Allow THC control when not in THC mode on Mill Options tab?
« Last post by RandyRay on July 14, 2017, 10:46:17 AM »
NO!  Don’t use it!  It takes away control from the THC On Off button on the main screen!  That option should ONLY be used for an Oxy-Acetylene setup where the operator will manually adjust Z height while cutting.

Please refer to the Vol 4 FAQ and Troubleshooting Guide under Q6 for a photo of the settings in question.

TMC3in1 FAQ / Re: Torch pauses

You most likely have delay times enabled in your spindle spin up and spin down settings.   Please go into Menu -> Config -> Ports and Pins -> Spindle Setup and make sure that for your General Parameters that all of the spindle delays are set to 0, since any other value will cause a delay.
Please refer to the Vol 4 FAQ and Troubleshooting Guide under Q5 for a photo of the settings in question.

TMC3in1 FAQ / Torch pauses
« Last post by Beginner on July 14, 2017, 10:38:19 AM »
After touching off and starting a pierce, the torch just sits there for a few seconds before it starts to move.  At the end of the cut the torch just sits there for a few seconds before it picks up to go to the next location.

TMC3in1 FAQ / Re: Do I need to power the ESS?
« Last post by RandyRay on July 14, 2017, 10:36:35 AM »
No!  Please do not provide power to the ESS via J6!  The TMC3in1 will power the ESS through 2 pins on the expansion header.  Also do not place the jumper on the ESS’s J4 next to Port 3 when you are assembling it.  In addition, do not power the ESS through Ports 1 or 2 with a BOB.  However, you may power the BOB from the ESS/TMC3in1 if it is low current.

Once the TMC3in1 is plugged into the ESS, all power is connected to the TMC3in1. The TMC3in1 generates the correct power for the ESS.

TMC3in1 FAQ / Do I need to power the ESS?
« Last post by Beginner on July 14, 2017, 10:35:11 AM »
I see the TMC3in1 plugs directly on top of the ESS (per the manual). Do I need to power the ESS as I did when I used it stand alone?
