General Mach Discussion / Re: 4th A axis irradical behaviour

Tweaki    I am getting ready to load a new laptop is .062 the solid locked down version...
thank you

P.S. not meaning to hijack the thread

Hi Jeep534,

Popular opinion amongst our members here says that version .062 is the only one to use.

General Mach Discussion / Re: 3d scanning with mach3

Hi Tony,

I think they are both valid ideas.

You would have to try it and see but the cheap measuring lasers may not have the accuracy you require. The high-end types (that measure the phase shift in the reflected wavelength) would certainly be good but may be way too expensive.

A high speed Z axis would be my preference but speed will surely be limited by the onset of surface contact bounce. I can’t easily see a way of detecting only the first surface contact on non-electrically conducting materials. This will give me something to think about.

Laser scanners were discussed some years back but the early prototypes never really worked that well and were, I think, just discontinued.
Mechanical probing, especially with 200mm travel and to a 0.5mm tolerance, using the Mach3 Digitize Wizard will work OK but it is such a slow process (typically an overnight job).

I have never seen this happen but there are some odd things occur with version .066
Try installing version .062 (over the top of your existing version) and see if that cures the problem ftp://anonymous:guest@ftp.machsupport.com/Mach3/Mach3Version3.043.062.exe
Make a backup of your Mach3 folder first (just in case you need to revert).

Mach4 General Discussion / Re: Is Mach4 really Hobby Material?

« on: January 17, 2018, 01:50:21 AM »

It strikes me that if half (this is my wild guess) of people who try Mach4 who don't carry on with it then is Mach4 really a hobby product?

There have been quite a few long established Mach3 users (and notable forum contributors) who have tried Mach4, not carried on with it, and then moved to using an entirely different software.

Tangent Corner / Re: Pyrography.

Hi Jose,

One question, do you use the method of varying the feedrate also with the laser?

For my laser power control I use constant feed-rate and variable PWM.

Hi,

Sorry but I can't provide much help - I tried hot wire pyrography but did not have any real success with it so went back to laser use.
All I can suggest is that you read through the HobbyCncArt topic, following any links given, and see if it better explains the technique. http://hobbycncart.com/forum/46-234-1
