As MASSO controls the Z axis movement directly when in THC mode, the axis can be used in combination of both gcode and THC logic.
At this stage we support THC with torch UP, DOWN commands through external units such as PROMA-150 but we are also working on our own D-THC design module that will sit next to the plasma and plug back into MASSO with the below features:
Self powered unit from MASSO's power supply requiring no external power source.
Fully optically isolate unit for electrical noise protection and isolation.
Input for ARC OK signal.
Relay output to start/stop plasma arc.
Arc voltage input from plasma 1:50 voltage divider.
To be able to set the required THC height via gcode using gcode S command.
Real-time height override option via MASSO screen.
Ross it not the controller the controller runs fine .. what masso did was take the mill features and add plasma . not being plasma guys they thaught the THC would
be simple so they lacked the controls to control it on screen and in the program . THC voltages change with velocity slow down . circles steel warppage
and many other reasons . masso has no way to over look a voltage change . no anti dive feature and other things like mach has and onter controller builders
if you looking to get a good plasma controller . I sugest a vital systems hicon mini swift cut uses them . thers an ESS warp 9 with there TMC3 THC these are the only
mach 4 plasma controllers that THC works well .. you can down load mach4 free demo there plasma screen and see the settings the used on the screen I sugest masso to do the same add that to there controller for plasma ..
another route is a uccnc controller and software and run a nuron thc unit this is a very good many oem use nuron and you have command cnc Linux
if your looking for a ohmic unit check Robot 3t
lots of us plasma guys share information on face book the cnc plasma good bad ugly . cnc plasma table builders
I been do plasma table designes for several years now I tried lots of controllers and motor . I build gear reduction units .Z axcess and every other part hear a pic of a build with a Z axis
I realy have heigh hopes masso can build a good plasma controller . like I said it does run.. a little slow loading large codes compaired to a pc based unit .. it just the thc part that not up to par .
Jcoldon, My problem is the Masso cost me over a $1000 dollars (cost of unit, postage and the heavy tax in Thailand) Masso sells a unit stating they sell a unit suited for plasma and is can't handle a simple THC.
My wife works 3 jobs and is the sole provider in our family and you know what wagers are like in a third world country, what you make in a day takes us nearly a month! This is to get an understanding how much this has cost us.
If they fix the problem I am happy, but if they can't I am looking at a new controller from a different company, How am I going to say to the wife give me another $1000 or more to replace the Masso cause it won't do the job it was bent for. Yer divorce papers that's what I will get.
That is were I am now, A plasma table that can't be used and a wife that is nagging me to get this thing working cause it has taken to long.
If Masso doesn't fix the problem they can ask my wife "Hay give Ross a $1000 to buy a different controller so he can get the cnc table working" cause I'm not brave enough for that.
@ross firstly sorry, just saw the messages now, all our forum notifications for some reason started going into spam folders and we missed all notifications.
I can totally understand your frustration and we are happy to help you on skype or something direct to find/fix the issue, for this we need quick communication and this will help you get the machine running on priority. Also, be assured that we will do our best to get your machine running on priority and if we cant then will issue you a full refund on the unit.
please email on support your skype ID and a time that works for you and will start working on this from today only.
