Mach4 General Discussion / Re: Mach4 Printer Port Discussions

Hi Peter,

As mentioned by Dave, the way in which our PC ID is calculated has now been changed so you need to contact license support for the new licenses (Mach4 & Darwin) license@machsupport.com

Please bear in mind that the '1 axis limit' issue has yet to be resolved so we will all have wait for the next Mach4 / Darwin release to be posted.

Hi Christof,

Welcome to the forum.

I was able to successfully get the software transferred to a newer, beefier machine... and read through the help/manual pdf...

That may be the problem, sounds like you don't have a correct install. Download and install the latest version from here; http://www.machsupport.com/software/downloads-updates/

can I set the M3 and M5 to be loaded when Vcarve produces its tool path

Yes, it's as simple as that.

Hi Stevenl,

When you run Mach3 - at the top of the display screen which name do you get following Licensed To: ??

Hi Brett,

Many thanks for the info - I have now chosen wider pulleys, slightly larger in diameter (still maintaining the 1.8 : 1 ratio) and a belt that would drive a Harley.

It all became pretty obvious once I thought about it but at the time it was something I did not consider.
I was driving a domestic sewing machine with a steel reinforced, T5, synchropower, timing belt. I set the correct belt tension and the driven load was well within the belt manufacturer’s specification. What I, rather stupidly, failed to consider was that the driven mass increases exponentially with acceleration.
At 300 rpm and with an acceleration, from stationary, of 0.6G’s everything was just fine but in the quest for speed I increased the acceleration to 0.8G’s and then the belt started to stretch.
In the interest of science I re-adjusted the belt tension a number of times and it continued to stretch until such time as the teeth pitch failed to match those of the pulleys.
Basically, with this type of belt the steel reinforcement is helically wound during manufacture and there is no real bond between the wire and the polyurethane so what started out at say 11 complete turns of the wire (within the belt) soon became 10.8 complete turns as the polyurethane stretched.

What I have learnt – I choose the wrong type of belt for the intended application.
