Plasma settings

How about some simple plasma settings

1 a setting to have a seperate. Z axissetting for . excell and ipm .setting for the thc inputs.

2 min max THC settings for the Z axis

3 a way to speed up or slow down all axis when cutting . or is this in the new G3

4 A way to disable torch breakaway input when probing . they way we can use the Round mount that does breakaway and torch touch in one .

Hi jcoldon

Could you elaborate on this please. What is it and how is it used?

2 min max THC settings for the Z axis

You can already increase and decrease the axis speed while machining using F11.

4 A way to disable torch breakaway input when probing . they way we can use the Round mount that does breakaway and torch touch in one .
My understanding of the torch breakaway is that if the torch is knocked off it's mount the alarm is generated to stop the machine. How does disabling the breakway signal assist with probing.
If the torch is knocked off the mount or the torch moves enough to trigger the alarm during the probing cycle then the result will be inaccurate.

I think he means extra THC options in the F1 menu for acceleration/feed rate and min/max travel (anti-dive?). Almost treating THC as a sub-axis of the parent Z axis? Currently the only option is for the touch offset. I guess it makes sense although I don't know if it should be slower or faster than the main Z settings.

Masso already has a separate feed rate for the Z axis when under THC control.
M667 F###
When a feed rate is specified in the M667 command the Z axis will run at that speed. It is generally used to prevent the Z axis overshooting when given the Up or Down command from the THC.
Changing the acceleration of the Z axis would have very little effect on it's movement.

So the MAX / MIN is a form of soft limit that would prevent the Z axis moving too high or too low but without the alarm?
In practical terms how would this work? How are the limits defined?
Is it a working coordinate based limit or a machine coordinate based limit.
How is it configured? If it is in the F1 screen you would need to enter Admin for each job to reconfigure Masso for each cut which would be painful.
What purpose does it serve? It would not prevent crashes and I can see it causing the torch to crash into the stock and preventing the THC doing it's job and causing poor cuts.
Any insight into this feature would be appreciated as it makes no sense to me.

Do you know what an excell is in relation to Plasma? I have been unable to find information in the feature or device.

Peter,

I think you find it is poor example of American spelling of acceleration.

CNCnutz thanks for the reply .

the Z axis control THC reaction control. i am talking about needs to be on screen . so when cutting you would be able to control the up ,down movement reaction speed. with reaction to fast the Z will bob up and down . have a fixed rate in a m667 macro you can not change it on the fly. having to repost a setting M667 every time to much work. Plus every cut is different .

second have a separate motor setting for the z axis were you can set Excel rate and IPM rate for when THC is on . this is not a 100 percent necessary . but would be really good for better THC control .

as you stated .. Almost treating THC as a sub-axis of the parent Z axis? Currently the only option is for the touch offset. I guess it makes sense although. I don't know if it should be slower or faster than the main Z settings.

Reason why it be good most plasm tables we running our Z rapids around 300 ipm . we have a separate ipm speed in the code for probing .sheet cam does that. So with a Z axis set at 300 ipm and Excel set at say 35 it fast and it need to be. rapids on the x y are like 1000 ipm . . now with lack of Z axis speed control when the THC is on the Z axis will be to fast making is hard to control the THC height setting .

having his setting . would allow a lower Excel setting and a lower ipm . that way when thc is off Z axis still has full speed rapids .

the min max soft limits are necessary in some cases. lifting a torch out of control off the table burns up a nozzle if the THC unit has a voltage miss read . or one goes over a hole or cutting expanded steel

some THC units have anti dive .the mini built in . what happens if there is a voltage drop below your setting .usually 80 percent if freezes down movement . voltage readings will change on some corners and small holes on a machine were there s a velocity slow down .

Settings necessary for good THC control . are thc delay antidive settings .up down reaction speed setting to slow down reaction . this stuff is in every good plasma controller

The best one I have used is vital systems it now uses the new mach4 plasma all the settings are on the screen. switch off set .pierce height .pierce delay cut height. THC delay .thc voltage setting and more. also check the proma my plasm they do the same and separately control the Z axis for better thc control

Plasma controlling the Z axis for THC is necessary . reading voltage and sending signals to keep that voltage dead on .good Z axis settings are necessary . voltage readings do change for many reasons wile cutting .

I really like so see masso add the above features they would have a killer plasma controller .

I keep getting answer like I don t see the need . this is why oem not using masso plasma

But in the masso mill and router there s every thing in there . I posted this stuff 3 years ago with masso

They never do any thing for plasma .

Good thc control .and a table built to do Hypertherm book settings . is what necessary for a good plasma table

The round torch mount . it has proxi senc what happens in lowers to do torch touch . it spring mounted so it get pushed up like 1 mm activates probe input .

since the mount is round and on springs and collision during cut ..move the mount like 1 mm the proxmity sen triggers all stop . there are 3 or 4 proxy senc on the mount

this is why i asked is one can disable the breakaway input when probing . not all plasma table builders are using mag mount for collision detection .

I think Jeff is struggling to get his points across. Maybe it would be easier if @masso-support has a look at the Vital ArcPro guide. Starting from page 10, some of the settings Jeff is trying to explain are there. I'm not that clued up with THC but I can see a few bits on there that do sound very useful like the anti-dive. The min/max are correction limits above/below the cutting height. Strange that Vital calls the pierce height the ignition height and cutting height the pierce height. Guide below.

derekmccoy the ignition height is only for a situation on a large plasma cutter. piercing thick steel were the pierce height is to high for ignition of the torch. it more an industry setting. small setup does not need it .

vital systems has one of the best plasma controllers out there a simple on screen settings bar or buttons in masso to controll responce of the THC inputs ON SCREEN NOT A MACRO so one can change on the fly

and a seperate velocity and acceleration setting When the THC is on to controll the Z axis motor this would be a realy good setup to control THC it be a start How hard would it be to add this masso support ???

thanks for the feedback and we will be adding some more logic in the next software update to automatically disable the "Torch Breakaway Signal" during the "Torch Touch" routine.

Dear Peter

How to adjust the rotation of the material plate when cutting with plasma, (the material is rotated by an angle relative to the x and y axis). Does the masso plasma cutting program have the ability to calculate the angle of rotation so that the program takes into account this rotation.
Otherwise it is a plasma with 3 axes x, y and z

I think taking the breakaway during probing just destroyed my Z axis.
The torch came down to probe, the mounting plate got caught, the torch broke away and the z axis kept diving, pushing into the steel and breaking the mount. Please put this back in or at least make it optional.
