General Mach Discussion / Re: Laptop with parallel Port

« on: October 11, 2012, 01:10:52 PM »

Hi Darryl,

This CNC stuff is going to be an adventure with much to learn but it will certainly keep the brain active.

I am going back a few years but this is probably the first item I made with my CNC machine.
The GCode was produced with the free software G-Simple http://www.gsimple.eu/

It was made from 1.8mm thick engraving laminate and cut with a 2mm dia. Endmill – the 6 pieces then slotted together and fixed with cyano super glue.

The cube has no practical purpose but if you want to give it a try the GCode file is attached.

Hi Niroleta,

The Velocity and Acceleration in Config / Motor Tuning may need adjusting for optimum performance, but it may be OK as it is.
You need to check your E-Stop and Limit Switches are connected to the correct pins and function correctly.

Other that that you should be on your way to making great things. 

Good fortune with your new machine.

Download a copy of the CNC611.xml (from your previous link) then copy that .xml into your Mach3 folder. That will take care of the configuration settings

You then need to create a new desktop shortcut to Mach3 (or modify your existing one) so that the Target is something like C:\Mach3\Mach3.exe/pCNC611
This new shortcut should then be used to launch Mach3.

Hi Niroleta,

I would need to see a copy of the manual to determine the correct pins for the configuration. If you could email me the Italian copy I will try to translate it.

Hi Niroleta,

It may be best to email Paolo (paolo@ideegeniali.it) to obtain a copy of the CNC611 Manual, if you do not already have it, as that appears to detail the Mach3 settings you need.

Hi Darryl,

If it's any help, the micro-switches I use are the Honeywell type which have 3 terminals (Common - NC - NO) and these are readily available on ebay.

You need to have your 'E-Stop' connected to a separate input from the series connected 'limit switches'. This way you can 'reset' then jog the axis off the activated limit switch.

Inkscape is pretty good at creating the .dxf files but there is a lot to learn if you are to use it well.

Although not always brilliant LazyCam (included with Mach3) will create the GCode from a .dxf.

This link may also be of interest to you http://www.rotordesign.com/servolite/body_dxf_to_gcode.html

Hi Darryl,

Welcome to the forum - no worries about being that young, it's a fascinating hobby, just take it one step at a time and it will all start to become simple.

You need to post your questions as a new topic in the general section in order to get reasonable exposure - this section is really just for introductions.

In my opinion you will be unlikely to successfully use a laptop computer without an external motion controller (such as the Warp9 Smooth Stepper).

Some breakout boards incorporate 'pull-up' resistors on their inputs (they go to +5Volts when open circuit) so 'normally closed' limit switches will only operate in the 'active high' mode.

Hope this helps a bit.

Hi Joerg,

Please don't make multiple postings regarding the same subject - it only serves to diversify any response.

Thanks.
