FAQs / Re: Mach3 setting and configuration (newbie question level )

« on: June 03, 2011, 02:43:55 AM »

Hi AB,

1) If you wish to travel at 10 units per then your line would be G01 X00 F10 (the F is the feedrate).

2) You perhaps need to consider microsteps (if set) in your calculations.
    Al,s excellent calculator can be downloaded from here  http://www.machsupport.com/forum/index.php/topic,16315.0.html

This is the result I get from the above image settings.
The scan starts bottom left and it can be seen from alternate lines that there is a slight delay where the laser turns on and another slight delay where it turns off. This delay is so small that it makes no difference to the quality of photos or other images processed by the plugin.

Really weird because your documentation clearly shows pin 16 as an output pin so EStop cannot work, yet it does ?

Something like this would be good.

Say 30mm x 30mm, Stepover 0.5mm, Feedrate 20,000 (not inverted)

Certainly a mystery.
Could you possibly post a picture of the result and a copy of the test image you are using please ?

You could well be right here.
Increase your stepover so you can study each individual line of the images produced.
Because the plugin operates in duplex mode (bidirectional) then if each image is produced by alternate lines it would indicate too great a delay in firing the laser after receiving the Mach trigger pulse.
(Not sure I have explained this very well).

ntlaser,

Do you have "Sherline 1/2 Pulse mode" checked in Ports and Pins ?

The only enabled inputs are Probe and Estop. Probe on pin 10 and Estop on pin 16.

Vicrider,

There seems to be some confusion regarding pin numbering - at least I am confused. 
EStop has to be on something other than pin# 16 because that is not an input as far as the one parallel port setup is concerned.

Found this one in my Mach folder - I have no idea of it's origin.

I have been following with great interest and you really don't need any help because you are sorting it out just fine.

( hint:  if you reduce the acceleration in motor tuning or use 'exact stop' mode instead of 'constant velocity' in general configuration it may help )
