Mach SDK plugin questions and answers. / Re: Impact engraving plugin

« on: July 26, 2015, 03:10:37 AM »

Hi Vogavt,

My apologies if I have confused the issue.  As you will have already read…

Andrea found that electromagnets ‘stall’ in the same manner as stepper motors ‘stall’ and he used this principle to drive his magnet from one phase of a bipolar stepper motor driver. This is probably the easiest method to at least get started with impact engraving and as you have mentioned another single axis driver board will be required. As only the ‘step’ pulse is required you may not need to fit a second parallel port.

In the quest for more speed and higher impact force I have turned to higher drive voltages and TTL / Transistor switching of the magnet but this requires some knowledge of electronics / circuit diagrams etc.

The whole process (and the software plugin)  is perhaps still experimental because I believe we have not yet found the best way so please report back on your progress and we can all learn together.

Could you perhaps post your .xml file of the profile you are using for this machine ( rename it to something unique ie. Bhoh.xml ).

General Mach Discussion / Re: After install newer mach3 version stuttering movement

I suspect the problem lies with the Leafboy as it's USB / driver software has been tailored to the earlier versions of Mach3. Their website says it is suitable for use with Mach3 R3,043.066 and it may be worth downloading their latest plugin and seeing if it makes any difference.  http://leafboy77.com/index.php/en/home/16-english-categories/mach3/usb-motion/card-akz250/1-mach3-usb-motion-card-akz250

It may also be worth contacting the manufacturers and asking the question.

Curious one this - which motion controller are you using ??

Hi Scipio,

Welcome to the forum.

My best advice would be to stick with Mach3, purchasing a license after you are satisfied that it meets all your needs.

(I have been using Mach2 / Mach3  for 12 Years now and although I have Mach4 I am still using Mach3)

Just post any future questions you may have as a New Topic in the General section.

I am pleased you managed to get it sorted.

An excellent looking (and performing) build - thanks for sharing the information and video.

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.

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.
