General Mach Discussion / Re: Mach3 Major Bug?
« on: June 21, 2015, 08:39:51 PM »
SO lets see your script. It all depends on what you are doing in the script and HOW you use the values.

NOW can you measure 13.846153846154 to insure that it is accurate ?? Can your machine CUT it to that degree ?

Remember that Mach3 is a $150.00 DIY controller running inside of windows (;-) There are concession that were made to make it all possible. ONe of those is accumalative moves. IF mach canot make a small move that is LESS than a single step then it adds it to the next move in the que and so on.

What is the minimum resolution of a single step for your setup ?

Post your script for review.

General Mach Discussion / Re: is restart nessessary after edit?
« on: June 19, 2015, 12:23:20 PM »
I would always USE feedhold , wait until everything stopped motion THEN stop. And yes you can edit Gcode then resume cutting either from the beginning or from Run from here or Set next line. IF you use set next line you MUST make sure all the needed modal values are set.

The Colons ( : ) are NOT allowed in Mach3.

Unless you include an F statement in the init string then Mach3 does NOT have a default feedrate .

(;-) TP

1015
HIYA Fred,  Macah3 actually set the feedrate based on the actual kernal speed deviation. IF you are running at 25K on kernal speed and the PC is actually reporting 24800 then yes there will be a difference in actual feedrate based on the ratio between declared and actual kernal speed.  25000 vs 24800 = .992   SO 100 ipm feed would actually be 99.2 .

Using IPR is a bit different  over using IPM. Yo have to get used to it.  AND I cannot say that mach3 actually does it correctly.  Are you by chance using CSS?

General Mach Discussion / Re: Spindle Relay Control Issue
« on: June 18, 2015, 03:02:09 PM »
I would guess there is a script or a brain OR plugin that is running that turns OFF the spindle when at HOME position or while homing.  It could be a function of the SmoothStepper Plugin.

(;-) TP


1017
OKAY,  (;-) FPR

 Feed per rev Verses Feed per min CAN change your feedrate  So it can change itself. Try turning OFF Feed per rev (G95) and set it for FPM G94) just a s a test

Set the active high/low to where it works. THEN look at the Script that runs the HOMING and see IF it is turning off the spindle.

(;-) TP

1019
Fred it is NOT your Gcode that is causing it. It is more than likely a corrupt load of Mach3 that is causing it.  I tested your Gocde here and there is NOTHING wrong with it. It runs just fine.
