General Mach Discussion / Re: Problem Using Mach3

Hi Fred,

This type of problem is generally associated with the pickup of electrical noise on inputs wiring.
Try increasing the Debounce Interval to 2000 or so (Config / General Config page). If this improves the situation then check that all your inputs wiring (e-stop, limit, home, switches etc.) are properly screened and earthed.

General Mach Discussion / Re: Help this newbie (engraving)

« on: July 23, 2015, 08:03:50 AM »

Hi Carlos,

Your board may be bent but this problem is usually associated with the machine's table not being flat and true with the machine's motion.

It is usual to fit a 'spoil-board' to the machine table then 'surface' this board (with a reasonably large diameter cutter) to make it flat and true with the machine's motion. Thereafter your PCB's will have equal depth of engrave over the whole surface.

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.

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.
