Yes i did. But that block hanging up screws up my cut height.
Mav68erick
Ill look at mine tomorrow to see what could cause that. maybe it has a burr on it from being chamfered and getting stuck

My THC might have been working but the block hanging up made me think it wasnt. I will video of what it does tomorrow.

This happens if the two screws in front of the Z axis acme thread become loose or the Z axis gets a big jarring. Easy to fix but you will need to disassemble the Z halfway.

I tried to loosen the 3 bolts and the block still hangs. I guess i need to disassemble the z axis, it didnt get any jarring so what exactly do i need to do?
wickedinhere
Got it fixed, the cable tray was binding not letting it stay down. Totally my fault.LOL

Hey mav what cad software r u using?
Mav68erick
AutoCAD r14 its like 10 yrs old. Some dxfs I dl don't show up. I got it forto work a bit on my new 64 bit laptop but it still crashes if you click to many buttons to fast

Well its been awhile been busy working testing out ideas being lazy. But noticed the new machine kinda sad I didnt wait a little bit, but being realistic I dont wanna route, I just like the added beefyness off the sides and the Z mount. Ive become away that with a hand torch hanging off the old model any movement on it causes it to rock some its not very stiff or rigid, thus it makes it hard to get square, which isnt a big issue to me except when I was piercing holes in .060 alm it pierces at .080 hgt. and moves down to .040 and comes out oblonged. But that was asking to much trying to use the pierced hole as a finished hole size.
Another is I thing I got the height control to work with aluminum Diamond plate but for say 16ga, when you have alot of pierces and what not I think the way the machine is set up its not very capable. It works good if you have a long cut and it holds height well, but once the sheet warps its over. Because your next touch off it pushed the sheet down -- Zeroes -- moves back up while the sheet springs back -- pierces and its screws up the nozzle.
Now when I get a change Im gonna order some 2 1/4 slat material rather then my 2 1/2 so I can lower my sheet closer to the water. I dunno if 2 Inch will fit and dont think they have 2 1/8. I could get 2" and put 2 1/8 shims under neith = ). This way I can somehwat submerge thinner stuff that has a lot of detail and see if that helps. I havent noticed the water getting to warm it barely got hit when I Was cutting 3/4 a friend wanted to see if it could, I both pierced with ramping it in and edge started it, cut good the bevel and angle of the drag line at the bottom was severe but had almost no dross what so ever. But I was thinking what If I plumbed the water to feed into a radiator on the wall with a fan to blow the hot air as extra heat and to cool the water down... Id Imagine it would work if the thing ran nonstop, But I think I need to figure something out before it starts freezing so I can change my water out, its getting bad.
Heres Some stuff I cut yesterday wanted to make a sign to go with all my cars signs ive hung up, cut out a Hotwheels logo and made this. Its 12" high gonna powdercoat the 1 Black or Flat Black and polish chrome / orange / maybe engine turn the SKull and Letters. Gonna engine turn some test pcs today when I get some hardware.

Heres what I was piercing the holes in, a 1/24 scale Rc truck, It didnt work to well so I drilled the holes by hand with a 1/16 bit. I layed out my first test piece and used it as a jig.

Made a top plate to, the stock radio equipment was junk AM stuff. so I needed more room to mount all the bigger electronics, as fast as the aluinum cut if I could just get the holes laid out or cut better, I could easily sell the 2 pc kit for 20+ bucks all day long on the RC forums.

Also made some Windspinners with Football team letters in them, Did a cool 5pointed spikey star, the things dangerous, Gonna do a 6 pointed more snow flakey one later. I got an order for 5 I gonna do, but 4 of them are inside a heart so I gotta draw that up today or tomorrow and get steel monday

Painted with 10-32 hardware, Flat black 1. Polish chrome on the skull and letters... looked like crap so I rinsed it off with water and was still tacky and stuck so I blew it off with air. let it set and then took an sos pad and rubbed it up and down, kinda did a semi brushed look. the skull is cleared the HD is not, I need to do it tomorrow, or maybe satin clear the whole thing
[IMG]http://i145.photobucket.com/albums/r217/Mav68erick/Plasma/Hd1_Painted.jpg[/IMG]
Im gonna make mine about 4' tall paint the letters gray first, then Wickeds favorite color ( Orange ) and do the sos pad trick.
I cut a tab in the back and tacked it on so you can hang it on a nail

The trick to cutting diamond plate is to have your cut height and pierce height above the diamonds and have your water level high. THC delay of .3-.5 second and no pierce delay. Some will even go into Sheetcam and change the post so their is no touch off after the first one its call *ref distance.
Mav68erick
well I got the diamond plate to cut ok, its cutting large areas of 16ga that was the issue, we were trying to cut windmill sides, well when we got done there wasnt much material left and my torch was dragging after about 25% of the sheet was cut, it was like a 12 x 20" area.
But the issue of no touch after first sounds awesome, especially cutting thick stuff where you dont need to touch off. Now this only works if you use the THC even on thick because depending on when making the table one side could be slightly higher then the other, I think mine is within about 1/64 so .015. But you could get unlucky and pierce the diamond at the lower level right next to the raised area and still bump it, Im not really gonna cut a bunch of it, but the refrencing Ill look into, 1 it will save a ton of time for not having to zero it self on small parts where warpage isnt an issue, and 2. if there is warpage it wont interfer with it piercing while touching the sheet.
Thx for the response.

Nice mav, I have been selling lsu and saints footballs like there is no tomorrow. I still hate orange,lol i will post come more pics in my thread of what i have been building.

Hey mav i am just getting around trying to figure out the THC do you have any tips? What are your setting for 1/16 and 1/8.
Mav68erick
hey wicked havent logged in a while havent cut much either to cold = P did cut some disc brake brackets for someone and motorcylce brackets.
I dont even bother with the Thc, If you have multiple pierces at it warps up the next touch off is gonna push it down pierce on top and mess the tip up. So I dont even bother since I havent ct anything to big yet. Or your tip touches off between slates and pushed the sheet below 0 and zeros itself off below a sheet and messes up. If It was up to me I wouldnt cut anything thinner then 1/8 it cuts so much nicer to.
Iam however gonna try to work on the warping issue by getting 2 1/4 wide slat rather then 2 1/2 so I can lower my height by 1/4 so my water level is higher. May also get 2" and use 1/8 thick pieces to shim it up so so I can lower it 3/8 from normal this way I can have water touching the bottom of the thinner sheets.
wickedinhere
Yeah i cut mostly 1/8 but i have been doing some 1/16 for some butterflies to keep the material cost down. I was just looking for some pointers, i finally got my tip volts to read right but my voltage while cutting will be 30 or so volts lower than what the book says it should be. It just raises the torch till it wont cut anymore.
jeepsr4ever
This means your getting divided volts. What cutter are you using? Also there may be a recall on the units that arent giving proper volts.
wickedinhere
I am using a hypertherm pm45, When it starts cutting its close to the target volts then drops off. I was using the divider card but then found out the pm45 has one internal. I then hook it straight from the back of the pm45 to the small box.
jeepsr4ever
Definately divided volts....check your support disk
wickedinhere
What am i looking for? Do you think its a problem with the pm45 or the little black box?
