Mach4 General Discussion / Re: Mach 4 and ESS latest update issues

« on: August 11, 2016, 04:14:34 AM »

Ideally we'd like to be running using the g62/63 codes to control the laser on z movement.

Just a note - the M62/M63 codes are not yet implemented in the Mach4 ESS plugin. It will happen but it may be a while.

Perhaps check out the ScorchWorks website http://www.scorchworks.com/Blog/category/cnc/

General Mach Discussion / Re: defining a scale coordinate for mach3

To multiply your current movement distances by a factor of 3 then go to  Config / Motor Tuning and multiply the ‘Steps per’ by 3. Do this for each axis clicking ‘Save Axis Settings’ after each change.

As an alternative you could go to the Settings page and use the Axis Calibration feature to set the correct steps per unit for each axis.

General Mach Discussion / Re: Two Steppers on Y axis

« on: August 10, 2016, 04:10:57 AM »

The recommended method is to have two drivers (one for each motor). One will be the Y axis and the other will be the A, B, or C axis (you can choose) and these two axes are slaved together within Mach3 setup.
For more details the Mach3 manual has information with regard to slaving two axes and homing (squaring the gantry).  http://www.machsupport.com/help-learning/product-manuals/

It's a process as I outlined in my last post.

Attached is a .png graphic which was converted to a .dxf and then an engraving toolpath (Gcode) created using Vectric.

Some laptops work just fine with Mach3 and the parallel port but most do not - I think you have one of those which does not work that well with the PP  

It's for this reason that laptops are not supported for parallel port operation, only for use with an external motion controller.

This is an example of what I think you want to achieve...

Initially a logo is found which is close to the required size (internet search).
The logo is then converted to a .dxf and scaled to the desired size (cad software).
A Gcode toolpath is generated from the .dxf (cam software).

Sorry to say but that would not be ideal.

It has a background size of 23.8 x 13.2 mm and when scaled up to the required 90 x 50 mm has such poor resolution that it would be unlikely to yield any i and j arcs.

Try to find something of the correct size and of a good resolution.

(You could use a CAD software to create a border 90 x 50 mm then perhaps insert some text with a font that contains arcs - the easiest solution perhaps).

You have to do some of the work yourself - I have no intention of doing it all.

1) Find (or design) a logo of the correct size, containing the required arcs (.bmp would be OK but .dxf preferred).
2) Use the full reply and additional options tabs to post your logo here.

I will convert it into a dxf and produce an engraving toolpath Gcode then post both here for you.

Post a dxf of the logo you require (highest resolution would be best).
