Jason,

I went through extensive web and product searches trying to do this as economically as possible (it's a hobby for me rather than a business). Ultimately, I ended up with an Everlast Power...

The micro-usb on the Arduino board is only used for programming the board. (I've had more success programming it with the shield disconnected during programming.)

The PC connects to the USB to...

Furkanyilmaz,

I'll try to answer the best I can. I'm not at home, so I don't have everything in front of me. But I wanted to get you some answers right away.

On the torch voltage.....

Don't get on the boards that often anymore, but happened to see your question.

I wrote a manual on the THC I developed. That goes into detail on how I connected to the PP50 CNC port. That might...

Sorry for the delay, I was off on vacation.

I looked at both of the files. The best way is to import them into Excel.

You had it set on "volts" when you did the capture, so the column that...

I PM'ed some ideas to you.

On thinking about it, I recall running into a similar bug with the IDE (I am using 1.0.5 also). I think the project file got corrupted somehow. I had to create a new...

You should take a look at the Arduino site. They have examples of including libraries in your programs. It looks like you don't have a library included. The other thing is that I'd recommend using...

Sorry, haven't been on the forum in a while.

Your attachment isn't valid. If you can load a sketch file and it runs, then you have the drivers loaded right.

You didn't say if you were using a...

Thanks,

I have not yet updated the schematic and board layouts. It was about $50 every time a did a new pass and I got to the point that it was "close enough" for me. The files are in Eagle CAD....

Thanks.

I had the kerf detection working great. I could cut a square with the 16 ga sheet at a 45 degree angle. In the process of refactoring (major changes to clean stuff up and integrate it...

When you are working with raw torch voltage you have a lot more issues with noise, isolation and negative (versus positive) voltage.

I've not played with raw voltage and I would think there's a...

While the software should be independent of the torch, the hardware is specific to the PP50 (which I highly recommend). Does your torch have a CNC interface?

George,

I did get all of your PM's. I've been working 12+ hours at my day job, so I'm not online much.

Based on the PM where you said you'd need help with the software - I'm concerned that...

Yes, that is one of the many I used.

If you want to build a THC, I still have bare boards, PM me. You can find design and build info on github, the project is regeg/ArduinoTHC.

It turns out that it was the tip dragging.

It had been so long since I ran the table, I didn't recall where the THC software was at (I'm always tinkering). I finally figured out that I had...

Jester - it didn't cut right, but if I job through the cut, it shows the right length. So, I figured if it could do it right when it wasn't cutting then the axis calculations are right.

Ram - I'm...

Hey All.

I haven't had any time for working with the CNC for quite some time. I'm finally getting back to it for a winter activity.

The PP50 is working great on my table.

So far, everything...

I updated the manual with directions. But, you have to download that :) The updated manual is on Git Hub. But, I've copied that section of the manual below........ When you download the zip file...

Thanks. They were bare boards. It just cost too much to get small quantities of boards made.

I got the PC boards back from the fabricator (SeeedStudio). I now have two versions. The one "flavor" I'm been working on all along that I call the "Shield" and a new configuration that uses an...

I've seen this same behavior on my CNC and assumed that the pilot arc cut out when the arc transferred to the ground through the metal and then restarted when the arc was lost. I thought I had seen...

Still waiting on the next rev of the printed circuit boards w/ the minor fixes.

I started working on making the THC talk with Mach. It took a while to find all the info I needed, but it wasn't...

As I'm waiting on the new rev of the PCB that addresses the last couple layout mistakes, I decided to try an Uno board. It's a smaller and cheaper board than the Mega. Without the LCD display, the...

I have been working on tuning the final filter stage. The graph below shows the difference between 40 uF, 68 uF and 100 uF used in the low frequency filter (for 60 hz).

10045

While the 100 uF...
