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

Hi Dan,

If it helps...
I know nothing about wood but as a comparison, the image in post #1001 is on plywood which was purchased as Birch Ply and the image in post #1003 in on what Ger21 suspects is Beech.

Hi Dan,

I don't really know if hard woods perform better or not, certainly a lack of the hard growth rings (often found in pine) is preferable. I think you just have to try different woods and see.

Just thinking out loud...
The original Mach3 plugin was only able to provide a maximum 50% pulse duty cycle so lower powered lasers could struggle to achieve the best results. Auggie has adjustable PWM pulse duty cycle (0% to 100%) so I am confident that good results could be achieved with as small as a 150 mW diode laser (although feed-rate may be painfully slow).

As we have already said Auggie is free software but it requires the 57CNC which incidentally is also an excellent motion controller for use with Mach4.

So I will need to put a 10k in line at the bob. This will go between the bob and the probe wire?

Best to connect a 10k resistor between the probe wire and +5 Volts (at the BoB end).
