I have a 2012 era bulltear 4x8 table.
I have been having trouble with over voltage errors.
The voltage in mach rises quickly from 45v to 55v when cutting and then kicks off with the error.
Candcnc...

If you put the usps tracking number into Canadapost.ca it will show tracking in Canada. In my experience anyway. Worth a try.

Built the tank using the table. Cut slits for bending and for welding the inner supports for the top. Worked good, but it obviously does add a bit more welding than using a brake.

Built a computer desk and a water tank for draining the table. Tank is 18" tall x 24" wide 48" long. Holds 87 gal. Works well. I have two 1-1/2" drains in the table that tee into a 2" strainer, and...

Finally got the new pwm in the mail. Everything seems to be working right. This is the first time I've been able to use thc. Happy happy happy.

Sounds good, looking forward to see what you came up with.

Adding an air scribe would be nice, I haven't been able to find much info on mounting one on a Bulltear table.
You did mention somewhere you were working on one, do you have a kit?
Do you have pics...

I got my new (used) dell gx620 pc. Have it optimized and ready to go. Cant cut with it until I get my pwm from candcnc though.
I will keep you updated

Tom wants me to rma the pwm. He thinks that's the reason my voltage is acting up. So I'll give that a try.

It's not air, I never had the air hooked up.
Ill try and see if I can borrow my friends pm45 one of these days, and see if the voltage acts the same.

Here's how the voltage looks, it hits a high of 22 in this short vid

Yes, I havent got the newer one yet.

Just noticed the PM45 has a very faint crackling or clicking sound coming from inside it near the back of it. It does not have the air hooked to it, so its...

If I unplug the stereo jack it goes to 125v
If I unplug the torch lead from the PM45 it still does it.
If I unplug the CPC plug from the back of the PM45 it goes to 242v
If I unplug the ethernet...

Is it normal for the tip voltage at idle to be jumping around? If I watch it, it fluctuates from 0-20v on the mach dro.
0,3,14,19,0,2,20,3,9,12,0,1,5,9,18,0,3,7,0,1,17,....... if you know what I...

I just read through jamscal's thread again, I must have missed it the first time through, but you told him that cut height should be at least .02 higher than the book says.
I have mine set at .06...

Could it be the torch itself? When I fire the torch in the air it is suppose to be around 135v according to tom at candcnc, on the Mach screen. But it still shows 45-50. That's when it has a flame, I...

Its integrated, I had the cover off and double checked all the connections inside, everything is clean and tight.

Yes it varies easy 20v while cutting with thc off, or on. Whats strange is that when vary the voltage 1v (117-118 ) in mach it changes from dragging to going really high.
Cuts fine with thc off...

32bit

It was a business lease return that came with xp pro. Vista was never an option.

Not saying its not the pc, but just seems odd...

Whats weird is,
If I set my voltage to 116 in mach, it drags the tip, most of the time, but sometimes raises it up till it loses arc.
If I set it to 117v, its about 50:50, sometimes drags,...

I'll send the cable.
"raise head on fault" is unchecked already. My THC delay is 1 sec. It seems that it is long enough delay, I can watch it do the pierce, and the height seems ok as it starts...

I got my new cable yesterday. It is now showing proper (maybe slighly high) voltage on the mach dro.
When I did test cuts with thc off it seemed to read in the 125-135v range.
When I tried thc on,...

It looked like maybe they had pinched some insulation in the green plug on one wire, so I took them all out, re-tinned the ends with solder, and put them back in with no change.
I sprayed contact...

I just tested the voltage out of the CPC connector on the back of the PM45 and I have 3.24v (terminals 5,6) when I jump the arc start terminals(3,4) So it has to be between the cord between the...
