    You you wanna go 1 step further, you could put dowel pins in the front plate of the 2 big rectangle bulkhead assembly to line the bearing up on the plate it attaches to as well......

    If I'm CNC machining everything including the bearing (which we did but apparently not as I hoped), the patterns should line every thing up.
    I understand what your doing and it's good.
    I just think my guys should have had it spot on to start with.

    Hey guys! Sorry I have been Mia. I work in the petrochemical and power industries and work has been pretty much non stop since I placed my order. Generally this is a good thing for everything but your life out side the gates. Anyway, about the only progress I've made is picking up the steel and getting the vfd installed on the mill so that I can drill the holes for the head mount. I'm also in the middle of rebuilding my plasma table which has been a much larger project than I had intended, but that's almost complete.

    July should be a much slower month so hopefully I can report back with a better update.

    We all know how this goes... I just got done doing a bunch of updates on the install files, found some bugs. I can send you the link when needed.

    IDK, Its a short machine so it should cut decent.
    Its when things get long you start getting problems with whip, sag, etc.
    No tru spindle so everything has to be cut... no guards... no plasma ground that I can see. Only way to program is to use sheetcam and CAD and manually bring every round tube wrap in and manually lay everything out.

    Not a bad setup, but at 7k for a 6' version I can only imagine what he wants for a 20 foot, plus it only has 3" capacity.


    I got the new head assembly installed and lined up, also got the center support for angle and thin wall material done and it works great. I cut alignment ears for 1.5", 2", 2.5", 4" and 6". I only need to use 2, not 4 though. I let the aluminum jaw touch the stop for 2 sides, then tighten the jaws, then let the other 2 jaws touch the material and tighten them where they're at. Takes less than a min. to switch between materials. I can actually leave 3 in all the time, 2 for 2" and 1 for 4" and it allows me to swap between 2" square and 2x4 rectangle in a matter of seconds.


    The center support doesn't actually have to be in the center either, 6' back on a 20' long stick actually works really good, and once the 4th. axis gets up to 10 foot I can take it off if I need to. I will prob. cut the top half of the steel circle off so I can slide the ring out and remove the base. There is 14" of materiel I can't use anyway so the ring can stay on the material the whole time but the base would get in the way.









    Problem now is the twist deflection since the chuck turns from the back of the material. There is a little bit of a whip as the material starts and stops where the back stops but the front continues to move a little, plus any twist in the material means the material doesn't stay parallel, in other words, the back may be at 90 degrees but the front could be at 94 degrees. This is only a problem for angle and would be an even bigger problem when I am wanting to do 1.5" thin wall materiel for gas tank or battery trays.

    I called Lance and said I was gonna start working on a way to turn the head to eliminate that problem and luckily he was already working on something similar for another project. He sent me the files for the ring gear, the nema motor and the small gear for the motor as well as the part numbers so I could order them.

    I already modeled up the ring gear mount assembly and designed a plate to bolt the motor to the bulkhead. This is actually a very easy mod for my existing setup. I will just have a ring machined that is threaded that will weld to the back of my current head assembly, I can use the dowel pins to line the ring up, then drill the big gear to bolt to the welded ring.

    I will leave the motor at the back of the machine in order to do round tubing, i'll just disconnect it and connect the front one when I am doing angle. I then just have to change the 4th. axis ratio on the computer to compensate for the front gear ratio.

    Happy I could help.
    Make sure you leave some slots to adjust the gear motor position, I'm not 100% on the mesh distance. A lot has been going on since that drawing .
    Like a lot of the gear rack setups a spring tensioned motor might be a good idea?

    Using the machloader you can make a new profile based on your current one then mod accordingly.
    Only thing I don't think it doesn't do is copy/paste all the macro codes.
