Post Processors / LazyCam post processor for Mach3 laser operation.

« on: February 19, 2018, 05:55:53 AM »

This is my LazyCam post processor (incorporating the M11/M10 commands) for Mach3 laser operation.

(Please note that Mach3 version .057 or later is required for correct operation of the M11/M10 commands).

Judging by the photos that you posted, you never did quite get to the same level of fine detail in terms of cutting out the bicycle as the pros? How fine can your setup get do you think?

Strange comment to make. Perhaps you need to read a few more of the posts.    http://www.machsupport.com/forum/index.php/topic,12444.msg102590.html#msg102590

Post Processors / DotG post processor for Mach3 Laser operation.

« on: February 19, 2018, 04:36:55 AM »

This is my DotG post processor for Mach3 laser operation.

Because the M11/M10 commands only operate upon axis movement and because DotG only produces it’s 'dot' output when the X and Y axis are stationary an imaginary B axis has been used to enable correct operation.
Within Mach3 the B axis is enabled and set-up with low step value - the Velocity / Acceleration can then be set to determine the ‘dot’ burn time.

Have you perhaps turned off  'Jog ON/OFF'  on the main screen ?

General Mach Discussion / Re: "Ref all home" sets wrong coordinates (XHC MKX-IV control card)

Do you have suggestions which manufacturer to looking for? I have Yako MS-L Servo drives for Y axis -> http://www.yankong.com/EN/index.php/proview-60-26.html At the moment I am not at work to give models of other devices but I can give more info if needed.

I can't recommend anything in particular, however, I use a Warp9 ESS with Mach4, a Warp9 USS with Mach3 and a Pokeys 57CNC with Auggie.

One more question - is it possible to change strength of motors so CNC turns off in case some cutted parts move away from their original position (small parts) and goes between something? I know to use tabs, but I cut plywood and it is not so stable to have good tab all the time. And too strong tabs cause too much time to remove or may damage surface of playwoon when removing.
At the moment motors needed to apply too much power to make losing steps and even when it happens it mostly turns off only one motor and all other motors continues their job which is bad.

You need to feed the servo fault condition back to Mach - that way Mach knows to pause / stop program execution if any servo has faulted.

We are seeing so many reported problems with this far eastern control card your best option may be to replace it with a known reliable controller. Alternatively why not contact Alex He directly, he may have info on an updated driver etc. xhctech-alex@hotmail.com

Hi Art,

Thought you may be interested in this which is something I had not seen before. It is a 3 axis scan head which can scan very large areas by obviating the requirement for an F-Theta lens system. https://nutfieldtech.com/3xb-3-axis-scan-head/

This pic. is of a Nutfield 3XB. Obviously the beam angle changes dramatically during the scan but the focus remains constant.

Certainly something for me to investigate further.

Wouldn't it be cool if along with laser cutting, it also had a sensor that gauged depth at the same time!

Something for you to design perhaps ?

The Mach3 plugin will reproduce 8 bit images (true shades of grey).
DotG produces 1 bit images (illusion of shade by dot-dithering).

If you contact Tomura directly he will send you a copy of his TomTom plugin.
