i cant find it @@ i only saw acolabaritive design board with Aryeh Eiderman which is there for quite some time @@

so you're not going to share?

pminmo,

how are your TB6560 layout?

Hi Bryon, what encoder model are you using? What version of Mach3 are you using? I have experimented with a simple 200 line encoder and it never works till now. I think it's the encoder's fault. It's...

Hello everyone,

I have been planning to purchase a VSD-E, as Tero said that servo stepper is available, and will be improved at later firmware versions.

Now - During my past, I have been...

Hi Jim,

It's been awhile again, =) I've spoke to the Campbell people and we are working together to create an environment and features more friendly to the HPR260 =)

Thanks for this post. It...

So, I just use mach3 to control the plasma trigger and the plasma does the rest, right?

Hi xjdubber, on second thought, you're right! I just keep thinking that modbus = serial port, so it does the work, but when I think more clearly, I need some kind of hardware interface for...

Well, we know CNC can be made for:

Profile
Mill
Lathe
EDM
Engrave
Route
and etc...

Hi Jim,

that was an interesting post about THC, very convincing XD

Oh yeah, I went through the Hypertherm Phoenix CNC version 8.000 Updates PDF, I saw that they have included a HPR series...

Hi Jim,

a floating head switch is... There is a microswitch built in inside the torch nozzle. This is to measure the initial height sensing. For instance, the torch positions to a position where...

Jim,

This is a big problem. I cant find anyway to utilize the ohmic sensor, in other words, I cant perform an IHS. I would like to know whether HPR260 torch has a floating head switch or not.

Jim, I love your spirit very much! =)

I didn't know I made the right choice in HPR260 =P

Hmmm, does HPR260 has built in Ohmic Sensor or Ohmic Detection? If it does, I can easily interface is...

Hey Jim

Just want to tell you that I really appreciate what you have thought me about THC. I know you work for Hypertherm, but there are peoples outside who are trying to flame someone for a...

Nevermind then! You have helped me ALOT!!! Thanks Jim!

The owner of Campbell THC replied recently, he said that I can add an ohmic detector. What a whiz! =)

Teehee!

I don't think it has a Ohmic Contact Feature, but he did say this:

" It looks the voltage is in range. I have not found if the HF is on all the time or just when peircing. It...

Hi Jim,

I've asked all of them and I find CampbellTHC is the most suitable, because they seem to work for HPR260. I am actually building my own CNC.

Hi Jim, thanks for the detailed answer!

Does Campbell THC, DynaTorch THC, CandCNC THC, or Torchmate THC available for these powerful features?

How does Ohmic plate contact works? What is initial height sensing?

Hi rpgdeity,

It will be interesting to build your own CNC Machine. If you're talking about machine self accuracy, its better to use alumininum with slots in. It really helps you out on making a...

Hello friends,

I will be purhcasing a Hypertherm HyPerformance HPR260. I want to have a reliable but affordable torch height system. I will not use Hypertherm's CommandTHC, it kills my budget. Any...

Hmm, is PIV a new method of closed-loop correction? How is it better than PID, in terms of smooth operation?

Hi Mariss, I really appreciate for the time used in writing this analogy, I saw you kept online for more than 1/2 hour, thank you very much!

Like your explanation says, I am driving a car (PID...

:p since you have asked, I will be using GD's Pancake Direct Drives, and maybe a 300W BLDC Servo. I am considering VSD-E or Panasonic A4 Drives, or Mitsubishi Drives, or Gecko's G340.

I'm...

The gas pedal idea simply pictures it into my mind at ease. Thanks Mariss!

But what are these 90 degree less phase margin, and how are they connected in different servo modes?

Thanks Bob, how are the feedback systems differed compared to velocity and position mode?

The word - No feedback to the drive unit. This scares me now. While debating the question on whether to use torque mode or velocity mode, Many of them said torque mode is best for beginner, but - no...

So, if i am a begineer, I should start of with torque modes. And slowly I will learn how to tune velocity modes, because smooth operation is very critical in flame cutting. Flame cutting needs to be...

Thanks for the tip guys, I guess I will go for Velocity Mode, but how do I start tuning it? P, I, D?

Hmm Al The Man, seems like everyone's using Torque Mode. But for CarbideBob, this should be what I need. I do use Oxy Torches too, as I'm living across the other part of the world, so it makes more...
