General Mach Discussion / Re: IF you wanted to UPGRADE to MACH4 ??

« on: July 23, 2015, 07:48:00 AM »

give it a year.........

I bought my license last August, so I already have. And that's what I said last year, but today, imo, it's not much closer now than it was then.

I am starting to think it will be a few years, if ever, before I will be using Mach4.

General Mach Discussion / Re: Spindle wont turn back on.

« on: July 23, 2015, 07:43:22 AM »

I am presuming the spindle is started with an M3 command at the beginning of the Gcode. If you stop and then re-start the program run you need to click on the Spindle button (or use F5, or other methods etc.) and allow the spindle to run-up to speed before clicking on Start.

General Mach Discussion / Re: Mach 3 Scaling Problem

« on: July 22, 2015, 03:22:15 AM »

Another Noobie in CNC world.
My problem is that I am trying to cut a small piece but Mach3 is scale X2. I am not sure what to do? please help!

If the finished X-Y size is double what you require then change the X and Y axis DRO's from +1.0000 to +0.5000 (pressing Enter after each change).

note...
This will affect the X-Y scale of the finished part but may cause problems with tool radius compensation under some circumstances.

General Mach Discussion / Re: dispensing liquid with Mach 3

Hi Juergen,

Obviously it all needs tailoring to your specific application but why not have the actual dispensing carried out as an 'Incremental' move returning to 'Absolute' after the event.

Hi Juergen,

My thoughts would be (as I have already mentioned in an earlier post)  to define the A axis as linear,  move it the required amount to dispense the liquid (glue) then reverse its direction for a few steps to prevent the drips when the X and Y axis move the head to the next location. This can, in my opinion, be easily controlled from a macro function.

Mach 4 pp (Darwin) can do that to

Maybe ??

Although laser engraving is handled well in Mach3 unfortunately Mach4 / Darwin still has some way to go.

Hi Sprocketeer,

I am pleased you have found the fault and a resolution to the problem.

I think this just goes to show that we can all make very basic mistakes but, as a commercial enterprise, I would have expected AT to have checked and double checked their work before sending it out.
Still, it's water under the bridge and you can now move onto completing your machine construction and making stuff.

Hi Bill,

I am not sure you are getting this right because...
Direction relates to how the cutter moves with regard to the work rather than the travel of the machine parts (if I could explain this better then I would).

However, to overcome the particular problem that you mention then you could try reversing the keyboard assignments for the X axis in Config / System Hotkeys.
