Mach4 General Discussion / Re: M3 Probing error THC Pokeys
« on: December 12, 2019, 09:44:23 AM »
You are either running out of travel (need to make the max probe distance larger) or have a noisy/bouncy input signal. Lots of post on this forum on how to troubleshoot and fix noisy/bouncy inputs. This one good example.......... https://www.machsupport.com/forum/index.php?topic=42086.msg274439#msg274439

The values in the DROs are changing because your machine units are mm or the Gcode your running is in mm mode. This has been fixed but not in a build yet. It should make it into the next build.

2
Just add your probe height.

value, rc = mc.mcCntlGetPoundVar(inst, mc.SV_PROBE_POS_Z)
value = (value + .33)

You can add it in by hard coding in your script as above. You could also get the probe height value from a DRO on your screen or a register. Lots of ways to do it.

Mach4 General Discussion / Re: Mach4 and kingstar

The way I understand it KingStar is not going to be available to just anyone. Only high volume.  :(

Bravo! Now that's good stuff right there!

Regarding noise.........

Your motion device may have a filter setting for input/s. That may be a helpful software solution. Filtering like that just makes it so the first time the signal state change is seen it won't be reported as seen. It will have to be seen as that state for some sustained period of time before it reports the state change. In other words, a quick short blip of the signal would be ignored.

The better option is to fix the noise issue through design. Sounds like you have done some for that already but shielded cable is not a guarantee and only eliminates one potential sore spot (which can actually be magnified by the shielding if not done correctly).

Keeping all low level signals in a control cabinet (away from noise) and using only 24 volts on the machine can help a lot. Using optically isolated relays to do this also gives big benefits.

Adding a capacitor to inputs has the same effect as noise filtering in software.

Adding resistors to inputs requires the input to supply more current (push harder) to change state.

A combination of caps and resistors may be an option.

This link might help too. https://www.machsupport.com/forum/index.php?topic=25616.0


Regarding touchoff settings...............

Make small increases to your retract distance and play with it to see how it affects moves. The error you got is saying the probe move finished before the probe input changed states. If the probe input never changes state while doing the actual touch move, that is the error it will report. Increasing your retract distance will increase the distance it travels in a touch move too.

6
Sounds an awful lot like you have a noisy probe input.

But this says you do not have the settings in the touch dialog correct for what your trying to do.
"ERROR: No contact with probe"

Could it be some of both going on?

Good deal, glad you got it working.

Sounds like your launching wxMach and not Mach4GUI. Some lesser motion devices only work with a very limited version of Mach4 and their plugin can cause you all levels of grief. The authentic ESS is not one of them though.

No problem,

Also, make sure any variables (like machEnabled) in the scripts are defined and set somewhere (like the default screens do) or create your own suitable replacements.

This is a perfect example of why you need to always keep the default screen. Also, I would highly recommend when you start with Mach4 copy the profile and screen you plan to start your actual profile with and save each of them as something custom, screen and profile. I usually make the names match for both screen and profile. This way later on you have a exact copy of what you began with if you need to undo something, use for reference, start over, etc.

The cycle timer uses 2 bits of script. One in the screens PLC script and the other is in the screens screen load script.

PLC
Code: [Select]
-------------------------------------------------------
--  Cycle time label update
-------------------------------------------------------
--Requires a static text box named "CycleTime" on the screen
if (machEnabled == 1) then
local cycletime = mc.mcCntlGetRunTime(inst, time)
scr.SetProperty("CycleTime", "Label", SecondsToTime(cycletime))
end


Screen load
Code: [Select]
-------------------------------------------------------
--  Seconds to time Added 5-9-16
-------------------------------------------------------
--Converts decimal seconds to an HH:MM:SS.xx format
function SecondsToTime(seconds)
if seconds == 0 then
return "00:00:00.00"
else
local hours = string.format("%02.f", math.floor(seconds/3600))
local mins = string.format("%02.f", math.floor((seconds/60) - (hours*60)))
local secs = string.format("%04.2f",(seconds - (hours*3600) - (mins*60)))
return hours .. ":" .. mins .. ":" .. secs
end
end
