G-Code, CAD, and CAM discussions / Re: Sudden wild axis movements during program run

« on: July 09, 2014, 02:35:46 AM »

Hi Marv,

Pretty ugly problem you are describing, it could have many causes but I would be inclined to make a clean re-install of Mach3 (possibly an earlier version .056 ?) and see if that resolves the issue. Don't forget to back-up your Mach3 folder so you can copy all your settings etc. to the fresh install.

Two different GCode programs could be run alternately but not both at the same time.

However, it would be possible to have two instances of Mach3 (and two computers) which are synchronised (perhaps using interrupts) so they both work together.

I suppose it is possible - you can certainly move all 6 axes at the same time but then the feed-rate will be blended so all 6 finish the current GCode line at the same time. Overall, with two different contours, it may be slower than just using one spindle for the whole job. I can't imagine what type of post-processor you would have to use to create the GCode.

Some further thoughts on this…

By changing the active state of Output #1 to ‘active low’ the circuit can be simplified as shown below.

I agree with your findings - Unless you have a good reason to update then stick with the version you currently use and yes your license and .xml files will work just fine on your new HD.

General Mach Discussion / Re: Mach 3 Scaling Problem

« on: July 05, 2014, 11:46:58 AM »

Hi Greg,

The axis Scale DRO's take a bit of getting used to but for example +1.0000 is full size, +0.5000 is half size, +0.2500 is quarter size etc.

Hope this helps.

A big thank you goes out to Art for all his continuing hard work with the Darwin driver, which just keeps getting better and better. Excellent work my friend.

Another short video, this time using the PWM signal to control laser power thus enabling seamless engraving and cutting operations. https://youtu.be/8fUg6ebWut0

Hope your not suggesting that the Hobby user of Mach4 then has to shell out $1500 - $3000 on a PC.

Hi Steve,

Thanks for the detailed explanation.

I understand what you say and I appreciate the dilemma regarding the specification of the average modern computer but unfortunately that is probably exactly the type of computer the potential customers for the Hobby version will have and will expect to be able to use.

I wonder if the software teams writing the combat games, which can be quite OpenGL intensive, are facing the same issues ?
