ok so the box came today. im getting talked off because someone in the process asked roger for his cc info and we were under the assumption there wouldnt be a charge. was hoping we could clear that up. and i already have that box and its wired in. however im havimg problems with the AVHS. what are the chances the box i have is bad?

1. it keeps trying to cut a line from the corner to the first cut path of the piece. that cut isnt in the cad file at all so idk how to change that. ( ive just been manually starting it after that cut)
2. i have the AVHC/S whatever it is set to manual because when its at auto it keeps dragging the tip.
3. its not adjusting its height for material warp. when it starts a new cut it adjusts just fine but if it has to make a long cut its not adjusting its height to the material (probably because its not set to "auto" but thats another issue (no. 2)
4. i have to mirror everything before i cut it or it cuts it backwards. how to change?
5. i would like to experiment with a fine cut. i have the 45a fine cut cups, and set the machine set to 45a, what psi should i run for that? im running 80 for 65a stuff and not having issues but i think that might be too much.

For Issue 1 see videos 1 and 2 below. For Issue 2 and 3 see video 3 below. Issue 4 swap motor cable on port 2 to port 4, this will reverse the Y motor direction. Issue 5 I would recommend reading your Hypertherm manual, as it will tell you the correct air pressure, amperage, speed, voltage, pierce delay, pierce height and cut height.

Also have a look at the other videos in the VMD library as well as the TM Cad library under the link www.torchmate.com/university.
For CC info you can call in and talk to customer service, the VFC box is free of charge, maybe they are referring to the redirect fee of shipping to your new address. A phone call could clear up the matter.

that literally helped 0%. those videos are great for people who arent having any problems. i am having problems. those videos dont explain troubleshooting or how to fix specific problems. i understand how to work the machine. been working great for days. i need to fix some problems.

I take it you are not reading voltage. Click on Machine Settings and change Distance to Corner to 6.0, run another Job and watch the Arc Voltage on rights side of VMD software screen to see what voltage it displays. For 6 inches into the cut it will be cutting in manual mode where voltage will be reading anywhere between 90 to 120 volts before switching over to Auto mode and adjusting for height. If no voltage displays then it could be that you need to swap the arc voltage wires on the VFC box the red and black wires coming from the Powermax 65.
If it is reading voltage then per the Arc Voltage video you will want Sample Voltage On and you can readjust your Distance to Corner back to .5 or .75, this value is in inches and determines how long the AVHC is locked out before capturing the present voltage and switching over to adjust for height in Auto mode.

also. the trying to cut a line all the way to the first pierce point from the "0" only happens sometimes.

Video 2 above shows you how to output a file from TM Cad. Where in Machine Output, Device is showing Accumove Imperial. If you click on the GCode Panel in the VMD software you will notice the first few lines read G70, G90 and M06 T1, the last one being important if that is not there then the software will treat rapid travel lines as in your case as cut lines.

first off i appreciate the help. i know its a headache. you guys are helping alot. its working at about 90% now. just a few hiccups. i ran a job today and got it done but theres a few things i need to get sorted out. 1. if i put it in the corner corner (when the lines change color), it tells me "no object to cut" or doesnt cut whatever line is touching the border. so i just space it a little no biggie. (not worried about that rn.)
2. after datum and program zero, it sees the orientation of the table incorrectly. i tried cutting something that was clearly withing the table (and workpiece) perameters but it stopped the cut because it believed it was going too far.
3. its still trying to make a cut from the corner of the piece to the first cut lead in. (its not part of the cad design in any way, i checked for the g code you were talking about and it was all there and seems in order.)
4. its still mirroring everything. (i tried switching the plug as you suggested and it started moving both axes at the same time.)
5. this thing cannot cut a diagonal straight line to save its life. i brushed and blew out the tracks, didnt help at all. if there was any way someone could post a few pix of where the gear meets the track on the gantry (i see a weld and i dont think its supposed to be there) and in a box i have some spare rod bushings for some reason but mine are able to pop right out (they havent yet but i can with my finger.) idk if thats something. could a bend in the gears "axle bar?" cause it? or since it was welded could the "axle" be off center in the "axle housing" cause it?
6. its not calculating kerf properly. i set the cut path and all thats good. but the final product the hole was a bit undersized because of the kerf angle. i used a da grinder to flatten out the "bevel" but i wish to not have to do that.
7. with the "wrong perameter" thing, say its movin along making a cut then it came across a line that was already cut (everything was off i was making it work) it just dives and pushes the gantry up. avhc is operating ok as far as i can tell, (havent tried anything serious, just refering to warp adjusting)
on a seperate note, i downloaded tm cad cam 9 on my laptop so i dont have to sit out in the shop to design stuff. works fine no complaints there. however when i save it on my laptop i can only save as .fdcg (something like that). i have to go out to the computer on the machine to switch it to .gm. did i download the wrong version of tm cad cam or something? both computers have 9.
Thank you for your patience.

Sounds like a few things are going on.
1. NO OBJECTS TO CUT is either not having the item selected prior to doing the MACHINE OUTPUT or your CUT PATH is not at x0 y0. go to VIEW/SHOW TOOL PATHS ONLY. select your cut path and verify the coordinates up top or select and get the magenta lines.
2. The VMD sees your machine one way. Y+ moves that gantry down the table away from you. X+ moves the torch head to the right. If that is not how your machine is set up then either the machine will need to get moved around or a tech will need to change the settings for you.
3. Somehow your g-code is generating an extra M64 to tell the torch to fire prior to the first rapid travel.
4. Mirroring is usually based on either the G-CODE or the way your machine is oriented. see #2
5. Any discrepancy in the machine squareness, binding of parts, gears jumping track can cause issue. I would verify the squareness of your machine by measuring across the gear rack at 4 points horizontal then both diagonals. then you can do point moves at slow speeds to verify the WHOLE table it runs smooth.
6. Kerf is determined in the TMCAD based on amperage. You would have to enter the proper kerf when applying the tool path.
7. The AVHC and voltage. If you cut over something that is already cut the voltage spikes and the head dives. This is 'proper' operation as you don't cut where there isn't metal.
Overall sounds like either you need to spend some time going over the supplied materials with the machine to verify proper setup and operation of your machine. Getting a understanding of how it is supposed to operate would help you considerably.
Also I will suggest calling into our tech support line as most of this stuff can be resolved quicker over the phone then back and forth on the forum.

why is the head diving proper operation? it jams between the slats and lifts the gantry. thats horrible design. why not have it uhhhh retract when it gets the spike? i get that its not supposed to have to double back over cuts but still. its bound to happen. i did set the amperage when i was doing cut paths. hence how i know its having a kerf problem. the orientation problem is between the table and the workpiece not the table and the computer. so how do i get it to stop adding this part to the g code? (if its there i havent checked yet.) and i know tech support is helpful but im trying to eliminate all the (try changing this stupid little thing and call me back later) so i dont have to spend 3hrs waiting for them. i wanna make sure the weld isnt affecting anything or that rod or something simple i can change before the wait. the table is square that was the first step in troubleshooting the curvy diagonals. tracks are clean and all is well. but when its cutting for some reason it acts different. it makes dry runs just fine.

Being that you are having a few issues all at once lets start with overall basic operation of the machine to verify that each item is an "issue"
First. With the controller on can you move/shake/wobble the gantry by hand. If yes? that has to be eliminated or you are going to get movement issues. If you do a movement test at slow speeds do you notice any binding or shifting in the movement of the gantry across the table? If so then this needs to be eliminated as would cause the issue.
Second. When you generate an item in the TMCAD and CREATE a tool path the DEFAULT kerf diameter is .058 which is about 45-55 amps with a 45 amp tip. This can be changed in the TMCAD to create different tools with different diameters pending on amperage. Your amperage and FEED RATE will change the KERF pending on the outcome of the LINE SPEED TEST. You can then mic the line and enter the custom kerf size.
Third. AVHC and how it works is a comparison game. Voltage feed back from the plasma while it is running based on amperage/feed rate/distance is compared and adjusted to the SET VOLTAGE. So when your VOLTAGE drops to 0 while your torch travels over an already cut area the head does what it is suppose to... adjust the head to the input voltage which is 0 so the head will move closer to the material to get it.
So I would recommend not cutting over already cut portions of the metal as the AVHC is doing what it is designed to do.
Four. Grounding. Earth ground? Where is the plasma grounded too? direct to the material?
