LuLu,

How much bigger are we talking about and are the holes round ?

ceramics,

There is a good chance you have more available Parallel Port Outputs than just the two you have mentioned but if you are programing the Arduino yourself then you can easily multiplex the signals. Two outputs can provide 3 functions and three outputs 7 functions and so on. You can incorporate the M Codes (to switch outputs on/off) within your GCode program quite easily with a simple editor such as Notepad.

I have been using Mach for a few years now and it's versatility just keeps growing.

That's great Andrea, looks like you have the setup all sorted now.

This shouldn't be that difficult.
Dan

Quite right Dan, it should not be that difficult.

I am running Mach3 version 3.042.020 and using the latest DLL that Art has provided. (I don't think my xml would be helpful as pin assignments are different and I work in metric units - not only that, I don't want everybody to know it is licensed to Papa *********X  ;D ;D)

One thing comes to mind...... The pluugin reduces my laser power density as the axis slows (decelerates) at the end of a line and ramps it up again as the axis accelerates during the start of the next line. If it didn't do this it would cut deeper at the start and finish of each line.
It is just possible that the feedrate you have set is not enough to see any output on the trigger pin so try increasing your feedrate to 300 or something and see what happens then. Just a thought.

Hi Wojtek,

You are not alone, I can never get the Mach diagnostic LED's to work, they used to once.

I use Parmon for parallel port monitoring and you can download it from here http://www.geekhideout.com/parmon.shtml It is simple to use and will show if your LPT port is working or not.

General Mach Discussion / Re: Bug in formulas
« on: November 30, 2010, 01:05:51 PM »
Just my opinion, but I think that a single drive on a 48" gantry is probably asking for problems way beyond this issue. Although, as you say, it is not easy it would perhaps be better to concentrate on getting your machine square and to use slaved drives to better distribute the torque.

There may well be a bug in formulas, so what, it's no big deal - move on and get your machine right, in the long term it is a far better solution than a software 'fix'.

Again, just my opinion.

Hi Dan,

I had a quick look at your xml.

You have the output configured to pin 8 OK but I also notice that motor3 step pin and motor6 step pin are also shown as configured to pin 8 - perhaps something to check.

Now this is a stupid question but you are running the full licensed version and not a demo ?  licensed to Abdul Mahman ?

Don,

There is lots on the forum if you do a search for 'auto tool zero' or 'touch plate' it may seem difficult at first to set it all up but as you get into it then it becomes more doable.  ;)

Sorry Don I was getting confused between Ref Home and Auto Tool Zero. Changing your step values has probably altered your home position.

I, along with many others, use the Auto Tool Zero (as described in the second half of this page http://www.cooperman.talktalk.net/files/17.htm) perhaps you may consider this as a better way for tool zero.
