General Mach Discussion / Re: Faster output

« on: March 23, 2013, 03:17:01 AM »

That's strange because I use Mach3 R3.043.066 and the M10P1 / M11P1 work just fine here with my laser so perhaps have your configurations set up incorrectly.

The M10P1/M11P1 commands produce a signal on Output#1 which in turn should be configured to the LPT port output pin of your choice. The chosen output pin number should not be enabled for any other function (ie. spindle) within your configuration.

Sorry, but I don't think the .ngc file extension is a supported Mach3 format.

Probably need a better image than the one posted but I can get the outline engraving, minus the circles, easily enough if it's any help to you.

Hi Shane,

Ideally you should not have the Kernel speed set any higher than you need it to be.

I often run GCode in excess of 300,000 lines of code and I always make a point of turning off the Toolpath Display before hitting Cycle Start. Problems here, I think, relate to the graphics card capabilities rather than the PC, but I may be wrong.

Hi Boris,

I think you need the wiring diagram of the breakout board you are using to establish the correct connections.
Obviously there must be exceptions with a 36 pin Centronics connector but all the breakout boards I have ever used have a DB25 connector so the PC to Machine LPT cable is straight through connections DB25 to DB25.

G-Code, CAD, and CAM discussions / Re: High detailed .dxf file -> Pronest 8 -> Mach3

Hi Ashcroft,

The ProNest delays you are experiencing are probably best taken up with Hypertherm directly – they should be able to suggest the solution.

Within Mach – if you are getting the ‘crop circles’ in your toolpath display this is because the GCode is intended to run in Absolute distance mode (G90).
Goto Config / General Config / IJ Mode and select Absolute – then click Regen. Toolpath and your display should be correct.

I don’t have plasma so don’t know about the other problems but I had to add a Feed-rate to your GCode and reduce the Dwell times, replace the M03/M05 then it ran OK with my laser. So overall it is, in my opinion, a good .dxf and a good GCode that you have generated.

There is some more information here http://hobbycncart.com/publ/cikkek/mach3_temaju_cikkek/switching_a_laser_under_mach_control/8-1-0-29 but I have not tested the performance when operating via the ESS.

Hi CD,

I don’t have plasma or use THC so this response is not based on experience...

My best guess, or what I would look for, would be electrical noise pickup on, or associated with, the THC Up signal.

Perhaps check cable runs, shielding, grounding etc. and if necessary fit filters, ferrite's etc.

Hi Jumla,

A couple of things you could try;

Check the voltage level of your LPT Port 1 to make sure it is 5 Volt TTL standard and not 3.3 Volt TTL.

Try configuring the Digital Trigger output as Active Low (this then connects to your laser PSU’s  TTL(L) input).

Choose an output pin number for your Digital Trigger that is not used anywhere else in your setup (even if any conflict of pin number is mapped to a different LPT Port).
