Anyone located in Colorado Springs?

The ground are fine - checked by the electrician, the code inspector, and today by me.

Well, I certainly would not question that panel of experts.

Tom hasnt provided a tangible list to check at the start or in the current. Would be awesome to have an actual list!

Do you have these manuals?

The table has been moved, set back up, and the stepper ran out of data error happens, the DTHC according to MACH is always on no matter if I turn it off, the torch only fires once until I unplug the hub, when cutting the torch fires for about 1 inch then looks like it lifts, shuts off and continues motion of the cut. Ill upload a video later.

With your torch lifting during the XY move and them shutting off, your DTHC is def on and I realize you are having trouble shutting it off. I would completely eliminate the DTHC equipment and just use XY motion for testing and see if the DTHC has something to do with the data feed being stopped.

Right, the master electrician who ran and hooked up the line or the master electrician who signed off on all the electrical for the regional building authority or myself dont know how to check a simple ground. The electrical grounds worked at the last place and they work here. I know it may be a tuff pill to swallow that the system you sold me never functioned as your website reads or you advertised. Problems from the start all the way to now.

Instead of talking in riddles you could just provide a punch list of things to check with actual instruction. Instead your combative and dismissive. Hey brother you sold me the faulty system not the other way around. I appreciate you all trying to fix it multiple times but you failed and left me hanging.

Now when I post of a public forum you are “stepping aside.” You have been on the sidelines for about 9 years. At what point in time are you going to stand behind the product you sold me and are selling.

I do, I have read them again along with the manual and all set up per the manual.

I will try that in the morning. Thank you for the action item.

In one breath you say the grounds are good because its the same as before it moved and it worked then (?) and then in another you claim it NEVER worked in the last 9 years....which is it?

I asked you specifically about the error screen you got and the screen shot, and you ignored it several times . I told you it appears to be NOISE from the plasma firing and that was ignored. The hub is appears to be locking up from noise and that kills the DTHC . If the ESS shows an errror it COULD be noise as well . Noise into the PC can cause all kinds of things to happen.

If you look in the DTHC manual about grounding you will see that you DO NOT tie the table to a AC safety ground. The plasma workclamp is a nasty noise source and anything you tie it to will be injected with the noise . So if the table is connected to the same ground as the controls and the PC guess what ...you get noise into the controls/PC.

The table needs a LOCAL rod in the earth NOT for safety grounding but for noise bypass . HF noise acts differently than 60 hz stuff.
Our voltage pickup and switch inputs are fully isolated to keep plasma noise out
Wires become antennas at higher frequencies.

AC grounding is for safety and not NOISE . It's okay to have leakage up to several volts of AC . That will not shock you . Letting volts of noise punch though at higher frequencies (EMI) is different.

Yes, sometimes you can get by with no table ground or the two grounds tied together but when you have problems that appear to only happen when the torch fires, you start looking at how that can happen.

1. Keep the plasma cutter several feet from the PC and the controller
2. Never coil the torch leads up under the plasma or under the controller or PCr
3. Unplug the AC from the controller and PC /monitor (removing safety ground from the chassis) and use an ohmmeter to check to the table structure, Meter from the table to the PC chassis. There should be an OPEN (high resistance) If its low resistance then find the common connection and remove it.
4. The 4 port Hub runs off USB . USB is noise sensitive . That USB cable needs to be very short and double shielded. Hub needs to be next to the PC .
5 The PC and the monitor should NOT to be in physical contact with the table structure. I have seen installs where the PC is in a metal case and was on a metal shelf welded to the table. Not good.
6 A wrong ground can be worse than no ground. Most buildings have a central ground at the main breaker panel . Sometimes they use a ground rod at sub-panels that can be dozens to hundreds of feet from the plasma or the controls. Two grounds more than a few feet apart are not at the same potential and the higher the frequency the more critical that distance is.
7. In rare cases you may have to run the torch cables outside the cable track if its together

When you have a noise issue (evidenced that it runs fine when the torch is off) you go to the source of the noise (the torch and the workclamp) and get physical separation for any control lines and electronics.

The error you got at first was a clue and you refused to answer if it happened once or all of the time.
Pull the torch and cables away from the table and get a piece of metal and fire the torch with it separated . Do not clip the workclamp to anything BUT the material.

When you move a table lots of things change. Everything from the local ground impedance to the proximity of cables and controls.

So...as my old EE professor once said " Ground is not ground". I did not know what he meant until much later .

The whole subject of EMI and RFI suppression and the concept of impedance to different frequencies is the subject of entire text books.

Finally: The workclamp of a plasma is not ground (positive voltage) and the electrode is the negative return , not a circuit ground. You can hold the workclamp and fire the torch with your other hand on the safety ground and you get no shock. Two different voltage paths. Like a battery sitting on a bench is not tied to he AC ground unless you do it physically/.
