General Mach Discussion / Re: G4 versus Sleep
« on: October 06, 2009, 10:15:44 AM »
Mach and VB exist in two distinct asynchronous threads. VB (the client) issues requests to Mach (the server). G4 runs in the Mach thread, sleep runs in the VB thread. Requests are not neccessarily run by Mach in the order they are sent by VB. Mach decides on the priority of the request i.e. in which order all the currently queued requests will be run. gcode is higher priority than updating the display.

isMoving() is arguably mis-named - it doesn't neccessarily have anything to do with axis movement, it might have been better if it were called "MachIsBusy()"

Hope this helps

General Mach Discussion / Re: Different speeds on lines and arcs

I may have misunderstood the problem entirely but... why are you programing the A axis rather than using Mach's tangential knife (TK) control? I took your code and removed all the A moves and just let Mach do its thing and movement (feedrate) seemed pretty good to me - definitely not showing the stop starts that the code you posted does.

Thanks JP - now working. FWIW I first tried this on my simulation Mach PC - i.e. no PP driver and although the Torch On/Off worked the TorchUP/Down didn't - the LEDs lit but no Z activity. Then I remembered a similar keyboard emulation issue I had a while back with the probe signal. It only actually works with the PP driver loaded. Sure enough the same seems to apply in this case.

thanks again

I have tried to emulate the Torch Up and torch down with keyboards in Mach3... but I don't see any effect in the Z DRO when running...
Any idea ?

cheers

Hi Matt,

In fact the plugin is not needed. My problem was only due to a missing THC On signal !!!

Now everything is in order and when emulating these signals (THCon, TCH up, THC down) Mach3 takes into account the height correction properly.

Hi JP. I too have been trying to simulate control of Torch Up/Down via keyboard emulation in ports n pins. I get the Torch Up/Down LEDs lighting on the Diagnostics page but no Z movement in the DRO. I've made a call to StartTHC (THCOn() throws a script syntax error) but this makes no difference. What am I missing?

Cheers

General Mach Discussion / Re: Plasma cut quality problem
« on: September 26, 2009, 12:00:19 PM »
Glad you got it sorted aj. I've been re-looking at your problem again today and just kept coming up with - CV is either turned off or it's not working - I just couldn't come up with anything else.

I took a look at your solution and I'm a tad surprised you're the first (plasma) user to raise this issue.

If it helps - I took a look and here's what actually seems (as far as I can tell anyway) to be going on. For some unknown reason and as you rightly say, the plasma screen doesn't have the screen controls for CVDistance and CVFeerate. BUT and here's the big BUT - it has the CV distance (invisibly) turned on and set to 0 - effectively turning CV off.

By loading in the 1024 set (the Mill set) which does have these CV screen controls, you were able to turn CV distance off and hence turn CV on.

I'm sure someone will tweak the plasma screenset and sort this one out in no time...

cheers

Hi SailFl - I don't do "beliefs" or "suspicions" - I give it the best shot I can with the evidence available.... I also don't gamble - sorry. ;D

Hi ajclay

looks like you're in exact stop mode. Add this: N0025 G64 (CV On)

Cheers

Feature Requests / Re: xml profile name in blue bar
« on: September 03, 2009, 12:58:21 PM »
Most likely I've misunderstood what you want - but - the xml profile is shown bottom right on the main program screen - labeled "Profile". That no good?
