So this is not necessary if your unit has a CNC port.
Any word? A working ATHC would make my life alot easier :-)Quote:

What gives? I *think* #5 on the CNC port will work so long as I have a place to hook the (-) to that does not have a 100K resistor, but I don't want to go inside the unit and hook to something that would void the warranty.
It seems 2 weeks should have been plenty of time to figure this out....
have you opened it up and change the the divided arc on the ROHS cnc circuit board
It seems that the arc OK is the problem from what I have read on CNC Zone. You can jump the arc OK to keep it on all the time, which seems to be working fine. The other solution is something to read your voltages that can supply the arc OK externally. CandCNC sells this it runs around $85.00. This reads the voltage at the tip and makes adjustments.Quote:

I got a feeling since burn tables has a proprietary thc your probably going to have to open your plasma cutter and solder something. I would try jumping the arc ok (leaving it on) first to see how it works. From what I have read this means when the torch is through cutting a part it would move to the next part without having to wait on the arc OK to be triggered. johndjmix did this for his plasma table build and it worked form him.
The Arc-OK is not the only problem, a problem yes, but not the only one. The main problem is the reading the plasma cutter puts out, even if I press the manual 'move' button, the ATHC does not hold to a correct height. The Arc-OK does not seem to work, which I don't think this is a problem with the Burntables control box, it is an issue with the plasma.
I still don't know why Everlast has not answered any of this, I guess if they don't know the answer they figure it is just easier to ignore it???? (PM's have been sent)--guess I will go try another PM...
if i want thc i am just buying the RAV-01 Raw Arc Volts Voltage Divider Card its only 42 dollars and tossing the one in my plasma would be easy to change since the everlast card has the pin connection labeled on the board . also checked out the DIGITAL CURRENT PROBE DCP-01 neat so you can see exact voltageAttachment 6635Attachment 6636 also hers a pdf on these things nice instructions http://www.candcnc.com/PDF/DTHCII-se...stall-full.pdf
yey Tacoma sorta pisses you off when never get a reply when need tech help . I feel the same way
Tacoma
PM me your number , will ask ray to u call u
The digital current probe can supply you with the Arc OK signal. It reads the voltage at the work piece. It's a simple incompatibility issue that is causing you some problems. You do not need a different voltage divider with the DCP-01. From my understanding THC reads the voltage in two places. If you use something different to read the voltage it should give you the proper signal to make the height adjustments. That is why burntables is wanting you to install their voltage divider card inside your plasma cutter. If you use something that works externally from your plasma cutter to read the voltage and supply the arc ok signal you will not void your warranty.Quote:

Burntables didn't want me to do anything other than tap into the torch (+) with a 100K resistor, and the torch (-). I don't want to do any internal modifications if I can avoid it (might be different if it was not a brand new machine).
The Arc-OK should work, but doesn't seem to when I try to use the THC, but since the THC doesn't work at all, I want to get the THC functioning before I worry about the Arc-OK (because it may start working)
Why not ohm out from the torch - 100K pit to the end of the two 100Ks and when you get a short, that is the negative one. Then make a clip in jumper and jumper that one out. No real mods to the machine and gives them + with 100K and minus without. We are 1:16 and 1:50, some mod will have to happen to get 1:20 either way.Quote:

Attachment 6644Attachment 6645Attachment 6646Attachment 6647I pulled my divider card and ran the resister color code , pin 5 is a 2 k resister not a 100 k and pin 7 is 100k resister so that pic of card is wrong . pin 5 resister is bands red -black -red - gold that 2k bet if you replaced the 2k with a 100k would solve your problem
Attachment 6648found out this diagram is wrong pulled my cnc arc divider card out of my everlast plasma cutter pin 5 is 2k instead of 100k but pin 7 is 100k its rite
If the two were reversed that would make his machine close to what the burntable people want in the first place. And the idea on the jumper would be shot in the foot as well if not 100K on both.Quote:

Better idea might be short them both out jumper clips (no mods to the machine that he is worried about) and add a 100K external to the control board line as needed?
Can you ID the resistor for 5 and 7.
Attachment 6650pin 5 is a 2 k resister not a 100 k and pin 7 is 100k resister so that pic of card is wrong . pin 5 resister is bands red -black -red - gold that 2k bet if you replaced the 2k with a 100k would solve your problem on pin 5
never jumper a resister can short stuff out adding more resisters ok but removing can fry components in a circuit board since like the relay on board is tied into some of the resisters . i think if he takes the 2k and replaces it with a 100k would fix his problem
