Hey mav how did you reslove the license issue in mach 3? I put the license in the mach3 file but it still says demo. I got the license loaded i had to rename it for it to work. Now i just need to find MP3000-DTHC and load it up.
Mav68erick
I emailed them my license and got another one and it worked. When I installed mach it was already set for The mp3000. But you need to add the processors from the candcnc disk into your sheetcam post folder and then set it to mp3000 thc in the machine setup in sheetcam.

The mach 3 has some weird name like ubobll and changes the back ground automatically. Try deleting mach 3 that came on your first disk and install it off the one that came with your electronic s

Did you use the mp1000 post or mp 3000 post the instruction say 3000 but then it says 1000 at the end.
Mav68erick
the Mp-3000 DTHC or Thc in sheetcam
wickedinhere
Ok so Mp-3000 it is. Thanks

Dont be in to much of a hurry unless your not cutting thin stuff, the height control has got me down = (
Was cutting some butterfly 3d puzzles today and no matter what I did, didnt seem to matter. The hypertherm cut profiles in mach arent close to anything in my book. And by the time the height control composents from the initial pierce voltage the specific piece is cut, It goes .080 pierce to .020 cut height andn then my z displays -.100+ z moves as I watch my z axis not turning at all or the torch staying the same distance over my sheet that is not warping at all I ahve so much weight on the edges. Some times it would go the opposite direction and rise up until it bound up the rising z axis and blind the fark outta me as I stared at the pretty light. I turned it off was pissing me off.
I started with 45amp shielded exactly what the book called for .080 pierce .020 cut height and 350ipm which seems ridicoulsly high changing my voltage in my mach 3 seemed to do absoultely nothing even if I moved it 50+ volts, I magically get a a nice straight cut on 70% of 16ga. .060 material and then the rest is at a wicked 30* angle it consistant in the same spot the torch is prertty square but I cant seem to figure why its doing this, I thought it was my other nozzle that barely got 100 pierces on it and it blew a hole out the side of the orfice and was pretty much junk. Funny thing is the bevel side is actually cut the past with no dross on that edge. the rest is horrid. It easily taps off but with the parts so small is annoying to deburr.
So I said hey lets try the fine cut same shit just smaller kerf. Im starting to wonder if its the water splashing up causing voltage issues and the dross problem the top looks fine the edges look fine, I even lowered the water 1/2 below the material and doesnt seem to help.
I know I gotta keep working it all I know is Ive seen better cut quality and I did better by hand. and I think on the butterfly atleast its corner speed and I cant shaeem to find where or if I can adjust it, because straight lines and big radius arc are fine, its the fast directional changes of the axis that cause slag. and I think it needs slowed down 80% on contours. I cut 3/16 curved flames and had little dross but still the massive bevel on the one edge.
Things I know arent causing the issues:
1. I have no binding that I notice everything moves fine and my load is low
2. I have 100% dry air that doesnt even make it to the filter I have before the plasma
3. I have 2 x 2 3/16 tubing laying on top of my sheet just outside my cut area
4. I loctited my pinions and theres no play in any of the gear to racks
Could my voltage be a ground issue? Ive seen ground clamps in water my sheet usually pools up with water on top of it fast but the purging of air through the nozzle blows it away from the torch pretty well. I havent grounded my table but that should only cause issues with the voltage reading right? seems to not effect the controller, although I still get random areas where my torch blows out if it goes off the sheet just a hair if a lead in was to close.
tomorrow ill get some pics of what it looks like so I can post it here and on plasma spider Ill work through it I just gotta tell people Im not cutting anything for them til I get this straightened out
Yeah there welded togeher

also cut a fly, but i lowered my torch .020 and the slots cut a little thinner and need a cut off wheel down them to get em to slide together. also gt a Dragon file I wanna cut but have no clue how to assemble it

the music is from my phone, that I was recording with.. I couldnt even hear it when I was filming yet it came through,

I think i got the wrong deflector for mech cutting on that fine cut setup... and I think im expecting to much when I was cutting the smaller butterflies to close together cuts, doubling the size helped some still takes a bit to deburr and clean everything up. I had enough deburring from that pos used bystronic laser my last shop I worked at got. for the money they paid it cut like crap, had people come in all the time and I spent hrs get it dialed in save my profiles next day wouldnt cut.

NIce it looks like you got the thc working pretty good what was the trick? I like staind.
Mav68erick
nope still off, the material isnt warping so I just turn it off, the SS pig I did warped so bad it lifted 1" or more off the sheet since it was 316L
oh well im sure Ill get to it but For thick stuff I think its to make up for inconsistencies in tables if the torch isnt exactly the same height in all directions or if the sheets already warped or bowed. Its just to frustrating to mess with atm
Mav68erick
I think im going to end up doing a wather chamber to raise and lower the water level... digging for pieces makes me a sad panda. Not to mention all the cuts on my fingers from catching the slats that are getting chewed up. I tried tabbing the parts .060 wasnt enough and a few things still fell through, magnet works but theres so much crap in the tray now its a mess so looks like raise lower water and get good wet dry shop vac. Oh and after 3 tshirts youd think I would learn not to lean over the table to get parts out.
this came out to cool, I wanna do the dragon but it has so many pieces!

Nice those r cool.

Quick question, How do i make the torch start anywhere i want? I move the torch where i want it then when i run the g code it moves about 12 inches then starts cutting.
Mav68erick
Jog it in the Corner of our sheet, lower the z down close to the sheet, and Zero out x y z on the top next to the machine cords at the top of the mach screen
dont click the reference buttons
or whats even easier because my keyboards so far away and Havent bothered to get the xbox contorller working, get it close zero it, and then move and square the sheet up under the torch
Notice in the start of the video all the numbers are zero at the top. Im pretty sure they say
Zero
x
etc.

What i did was put the torch where i wanted it to start and zeroed x and y but not z i guess not zeroing z is my problem.
Mav68erick
it will move from your zero location to what ever your first pierce location is based off distances from that corner. It wont work its way out from that corner unless you tell it to cut this hole then that hole and work its way out, its random, unless you make one part and nest it, then I think it will develop a pattern away from that spot
Mav68erick
got my DCP digital current probe today hooked up it works, decided to try to thc again what a joke, I went back through re set it up step by step and its just going hay wire, watched my z height go from the .020 set height to + 180 down to -.083 when it faulted and stoped with the nozzle in a hole obviously it dove but when it went to 180 it was reading like 150volts my target volts were 130 it should have moved DOWN >.< not to mention its delayed before it moves by then its to late, sad thing is it shouldnt move at all as the small area footprint of the matieral its cutting isnt warping
wickedinhere
Well now i understand i was thinking it started cutting at the corner. I cut a few more pieces then it started trying to cut too high but whats happening is that black block that hits the z home switch is getting hung up. When the block moves up and stays there and that makes the cut height all out wack. Have you had any problems with yours i lubed mine but it did help.
Mav68erick
nope hadnt had a problem with mine, did you do the z Reference to set the Z height in your mp300 post in the sheetcam folder?
