Masso tube plasma post

[iLefty]

Does anyone have or know of a post that will work with masso dthc? It uses m200 to sense the material and retract and pause for pierce. I am gonna try and run the mach rotary plasma post but I don't have time to hand edit code everytime to get the m200 to work. Any help would be appreciated.

Interested too. I have a Masso G3 with the pipe add-on. Have yet to run it yet.

I've provided an example of GRBL Plasma gcode below in the case of using a gravity slide torch mount with probe switch on the powered Z axis.
If you can provide me with the similar Masso G3 DTHC gcode for the torch touchoff section of the example below, I can perhaps modify an
appropriate .scpost for you.

Note that the S1000, M7, and M9 stmts are specific to my machine's THC Z Anti-Dive circuit (not a Masso controller) and you likely won't need those, but it's possible you may need a different set of stmts or none at all.

@Plasmamonster- I received your PM but the forum PM function does not appear to be sending you my PM reply, it remains in my OutBox. Please send me another PM with your external email addr and I'll reply directly to that addr.

[djreiswig]

The PMs stay in your outbox until the receiver reads them.

@djreiswig - good to know, thank you.

Here is something from the masso website. I will also link the page its on as there is a bit more info there as well. Thank you for any help you maybe able to offer. https://docs.masso.com.au/cam-post-proc ... quirements

Sample Gcode file
The following is a Sample Gcode file which includes the G200, M667 and M666 Gcode commands.
Note that there is no requirement for Probing Gcode routines in this file.
The M03 will automatically perform the Probing of the material surface, the Piercing delay and setting the cutter to the cutting height using information contained in the G200 Gcode command.
Because MASSO manages all Z axis moves while cutting there only needs to moves to the Safe Z height between cuts.

@iLefty - thanks for the masso dthc gcode example, and the link to the commands reference.
This looks doable in an .scpost for sure.
However, in order to collect all the parameters for the G200 stmt some additional inputs for the .scpost are needed in some form, either from post variables or new options added to the Jet Tool. I'm thinking that adding to the Jet Tool would be most user friendly. Initially I suspect just one new option is necessary, V- Cutting Voltage. This looks straight forward to do according .scpost documentation, but I've not attempted it yet. I'll give it a try later this eve or tomorrow if someone else doesn't get to it first.

[bLouChip]

Ok, it looks like the joke's on us folks. There is already a .scpost for this controller, use MASSO Plasma DTHC.scpost

I found that post before hand. I just looked at it again and the code is outputing a y movement. I need the y movement to be an "A Axis" movement in degrees. Not a y axis linear movement as I am using a rotary not a traditional plasma table.

[bLouChip]

Ok, understood now. Well, that .scpost seems like it would be a good starting point. I haven't done any plasma rotary yet (although I have a rotary I use in laser and milling), I'll have to study some other .scpost that does rotary function and see if I can apply to a variant of the Masso .scpost. I'm not sure what's involved in SC production of rotary gcode.

I know the Mach3 Rotary post will do the right movement. I need a blend of the Mach rotary movements and the Masso DHTC torch controller I think. Turns out Im not smart enough to know what I do and don't need. Im looking into it as well but again not 100% what Im looking for here.

[djreiswig]

I've toyed around with the rotary post a bit, but haven't actually run any of the code yet. I do believe that SheetCam runs the rotary axis in linear units rather than degrees. It uses the center axis as z zero.
I think you also have to purchase the rotary plugin for any of the rotary stuff to work.

I bought the rotary extension and i can get it to output to degrees instead of linear inches. My main problem is getting the G200 inserted into the post to make the MASSO react properly.

I think I may have solved the problem but time will tell. I have found gcode ripper program and that allows me to convert the y to a axis movements and you input the diameter of the material and it converts all y movements to a movements. Will report back if I have any luck.

[djreiswig]

You can edit the post and replace Y with A. You must be only using a 3 axis rotary for round tube only. I was setting mine up for 4 axis.
