Why a new THC? / Re: Is the TMC3in1 available yet?
« Last post by RandyRay on August 04, 2017, 09:07:24 AM »
Thank you for contacting us Michael,

The TMC3in1 is available for OEM customers (quantities of 5+) directly through Texas MicroCircuits. 

For single unit quantities of the TMC3in1, you may buy it from https://cnc4pc.com/tmc3in1-torch-motion-controller-3in1.html.  That would be a great place to also buy the required ESS motion controller that the TMC3in1 mates with.

Thank you for your interest, and let me know if you have any other questions,
Randy Ray

Why a new THC? / Is the TMC3in1 available yet?

I don't find information about how to buy this.  When will it be available?

Thanks in advance,

TMC3in1 FAQ / Re: Plasma off, but TMC3in1 shows voltage.
« Last post by RandyRay on July 14, 2017, 10:59:12 AM »
The TMC3in1 has a very high input impedance (or low leakage), which means that once its inputs are charged up to a voltage level, it can stay there for minutes or longer.  If your plasma unit left its divided Tip Volts output charged, the TMC3in1 will continue to read that until the charge slowly leaks away, or your plasma unit is powered again and actively drives its divided Tip Volts output to a new value.  You can test the input voltage measuring functionality of the TMC3in1 at any time by going to the appropriate Troubleshooting section

TMC3in1 FAQ / Plasma off, but TMC3in1 shows voltage.

My plasma unit is turned off, but the TMC3in1 shows a constant voltage of 320V or 857V or some other value.

TMC3in1 FAQ / Re: Touch off stuff? Please explain.
« Last post by RandyRay on July 14, 2017, 10:57:50 AM »
When you do a touch off, you then zero your Z in work coordinates, and then retract a known distance. This helps a lot with the pierce, since a large sheet of metal can vary significantly in height due to:
* Warpage (typically in thinner metals)
* Inclines (Not laying flat across your bed
* Physical damage or splatter type debris on top of the sheet of metal.

If you were always working with thick steel plate (1/2" plus) you could probably get by without a touch off. If you are working with thinner stuff (i.e. doesn't lay flat every time all the time), I would really say that you should consider getting a touch off

TMC3in1 FAQ / Touch off stuff? Please explain.

My torch isn't doing an actual touch off. It floats above the plate and retracts to different heights, but my DRO for both the machine coordinates and the work coordinates are changing from where they were originally zeroed.  So with the touch off, is Mach automatically zeroing itself?

TMC3in1 FAQ / Re: Where are the indicated Torch Up/Down signals?
« Last post by RandyRay on July 14, 2017, 10:56:27 AM »
The main screen of the TMC3in1 Screenset shows you the commanded up and down THC velocities that correspond you your Z axis motor tuning. 

Please refer to the Vol 4 FAQ and Troubleshooting Guide under Q10 for a photo of the settings in question.

TMC3in1 FAQ / Where are the indicated Torch Up/Down signals?

Where do I look to see the actual commanded Torch Up and Torch Down signals?

TMC3in1 FAQ / Re: Torch Up/Down LEDs flashing on Diag screen
« Last post by RandyRay on July 14, 2017, 10:54:00 AM »
The Torch Up and Torch down LEDs will flicker constantly when the TMC3in1 is alive and working.  These do not represent actual THC Up and Down commands, but rather the data controlling where the Z axis should go to. 

Please refer to the Vol 4 FAQ and Troubleshooting Guide under Q9 for a photo of the settings in question.
