Hi zavateandu, the machine has a big transformer inside, its abuot 30kVA if I am not wrong. I read that somewhere. On the plate of the machine and the documentation I have the input voltage is 400V...

@zavateandu , ok thanks, this is what is in the oposite corner on the upper side. All clear now for where to look. But sincerely I am concerned about another thing right now. On that day when I...

Hello zavateandu, what exactly you mean with "MAIN" ? Sorry I am new to this thing. I upload some pictures, which could probably help.

Hi, today I connected the machine to the electricity and tried to start up. What I got was a blinking SU-01 code in the main NC unit. I heard that fan was spinning and nothing showed up on the...

hi , I think I will have the same troubles. Hope not, but I go t a Stama MC530 machine from 1994, and I will start setting it up slowly. I hope you guys here will be able to help me. I am really new...

Hi asuratman ! Thanks for the reply. I plan to use that oxyfuel/plasma machine with Linuxcnc maybe with MAch3 too. I will experiment a bit with both, although my personal preference is for Linux....

Dear Matt, many thanks for your answer. I will get another Oxygen cylinder and yes, I have fire return valves on my torch on both hoses. I will buy another flashback valve for the cutting oxygen...

Hi, I think you should go for a 3 hose torch.

Hi all, I am doing a plasma and oxy fuel retrofit and I would like to do some tests with the oxy fuel torch. I am trying to cut a piece of steel but have been not able to cut it at all. My first...

Great work man, do you plan to develop a kind of GUI for it ?

Ok, sorry but I have no idea of what to suggest you. Low rotation and high torque you can achieve also with a good reduction gear.

Ok , I think if you need more power depending on how much for sure servos in my opinion are a way to go, but maybe again, depending on the exact construction and use you can use also a simple AC...

Ok, I am not sure if I understood it correctly. The relationship between the servo rotations er minute and feet per minute is a conversion of rotation into the linear movement. So to get it you...

Ok, got it, we will probably also travel way slower than the estimation I made, as the use will be for thick plates cutting of 20 up to 50mm , so probably its good to make a way lower estimation too....

I forgot, for the speed, as far as I know plasma cutters usually go up to 8m/min so we have a rack already there, but I need to find the correct pinion gear diameter I will go with. The motoer speed...

Thanks Al, what we have here as a source is about 50kg I think, Hypertherm Powermax 1650. Therefore put on the gantry some 50kgs more probably would not make difference. But yeah, maybe its
better...

Yeah, I plan to basically remove the color by sandblasting it, then re-paint and mount everything. I am still not sure if I will leave all 3 oxy torches or I will just leave one oxy and one plasma...

Nice work Al, if you want to see more about the machine I'm working on, you can find the pictures here: Index of /files/cnc
These pictures were taken at the day the machine came in here, and today...

Al, many thanks, for sure I will open a new thread for the planetary gearbox and linux cnc stuff. For now I can say that the gantry we are retrofitting here is about 800 kg, and it has rack and...

Ok, for planetary gearboxes, I will use those, probably a ratio of 5:1 or maybe even more, since we will work with thick plates and machine will mostly move slowly. I noticed that some people have...

Dear Al, many thanks. Just reading on the internet few things and I saw there is many possibilities. Yes, I see that would be no problem in using some DMM servos with its drives and then adding some...

Hello, I hope I'm posting this in the correct forum.

Ok my concern is about servo motor makers. Since I'm doing a retrofitting on a industrial gantry CNC plasma/oxy fuel cutting machine, I have...

Hello, I'm new to this forum, but I would like to clear a bit my doubts and if somebody can enlighten me and suggest I would really appreciate it.

We have bought an old oxyfuel / plasma gantry cnc...

Hi , I would like to hear some advices on what to pay attention when buying an used cnc plasmaa cutting table.

The guy selling it, says it was used only 1 year, but then another guy stepped in and...

Hi, I'm really new to that forum, and I saw a lot of interesting things.
I'm thinking to build myself a big plasma cutting table. We work with heavy stuff for mining and construction industry. So I...
