Modbus / Re: Modbus Slave simulator

« on: March 03, 2013, 01:35:20 PM »

Well Brett - seeing as how you put it so nicebly I might be able (in time) to forgive you - not so sure about the others though. That said WTF is wrong with the name Sysiphus - why some of my best friends (ney - ALL of my best friends) are called Sysiphus. OK so I only have two friends (well nearly anyway) and neither of them are ACTUALLY called Sysiphus but that's beside the point....

Brains Development / Re: modbus and arduino sketch working exept for PWM

« on: March 03, 2013, 12:50:32 PM »

I use my own modbus code on arduinos so I've not used the code you've linked to. HOWEVER if what you have works from the modbus test panel then that would suggest your arduino code AND your modbus setup appears to be working. As I said - your brain works here so I'd look there for issues. Have you RELOADED and RE-ENABLED your brain? Have you looked at "brain control../brain view"?

Hi Nosmo - my apologies - 'twas just my little joke (albeit one that got slightly kicked into touch.... oops better not annoy anyone else.... two apologies in one day would be to much... BTW where's MY apology from all those that deeply upset ME when they took the piss over Sysiphus - you KNOW who you are )

Anyway - moving on in the spirit of peace and harmony... Any more info on your requirements for the sim? - it can be as simple as a bit of CB Mach side and a VB script on the laptop - in fact in some cases you don't even need a second machine - depends on exactly WHAT functionality you need.

Hi fefenin - I may be misunderstanding but you have the arduino generating the PWM NOT Mach - yes? and the value you send over modbus to the arduino is used to set the duty cycle. Is that the case?

If so I've just tested your brain on arduino modbus and it works fine. -2 sends 255 and this is received fine. Likewise -1 sends 127 and 0 sends 0 etc.

Hi Andrew

Here's one I made earlier - season to taste.

Have you tried any of these

VB and the development of wizards / Re: Difference between Macro and Button Script?

« on: March 03, 2013, 06:00:48 AM »

presumably because of delays between the probe signal being asserted and the software actually seeing it.

Hi John

Are you using the parallel port or an external motion controller?

FWIW with the parallel port at least, Mach stores the EXACT position of the trip REGARDLESS of axis speed. It's able to do this because it both reads AND acts on inputs at/within kernel speed. Specifically - in a G31 it sends a step pulse, reads the input and if it's active it stores the position all in the time WELL before it THEN sends the next step pulse (which of course is the first step pulse of the deceleration phase (if any)). EVEN in a system that is capable of the MAX kernel speed where probing is done at MAX velocity this is STILL the case (of course your deceleration had better be damn good ). I can't comment for external motion controllers behaviour.

General Mach Discussion / Re: Lockdown (066) and Dev (067) versions, issues

« on: February 27, 2013, 12:24:01 PM »

Hi Hood - got any repeatable examples? - It's just that I've done a LOT of macro and button development recently using 066 (Mill) and thus far have not had any issues.

The change log is sadly out of date so no clues there.

Cheers
