General Mach Discussion / Re: Mach3 looks weird and torch won't fire

Perhaps some of those who use plasma systems may be able to help.

Hi Mr.Toad,

To avoid duplication this topic is already being dealt with by Andy (the expert) on the Warp9 forum;  https://www.warp9td.com/index.php/kunena/7-general-discussion/7576-woodworker-needs-help?start=36

With microstepping it is usual to select 1/8 if your machine parts and workings are going to be in Imperial units and 1/10 if it is going to be in Metric units.

Here is a calculator which will help you calculate the Steps per Unit for each axis; http://www.machsupport.com/forum/index.php?action=dlattach;topic=16315.0;attach=23771

Velocity and acceleration are a ‘trial and error’ thing…
Increase Velocity in steps until an axis regularly stalls (squealing noise) then reduce it by 30% saving the changes as you go. Acceleration is set in a similar manner. Then they are both finely adjusted for optimum performance.

SmoothStepper USB / Re: ESS and C11G help needed

« on: June 15, 2018, 02:32:10 AM »

Have you followed the directions given in page 10 of the C11G users manual and are you using the external power supply (connected to X1) ?

General Mach Discussion / Re: M10Px/M11Px synchronous with motion

« on: June 12, 2018, 08:22:33 AM »

Hi Tim,

I think it is the M3 / M5 commands that are causing the problem. Just use M3 at the start and M5 at the end of the Gcode and see if this resolves the issue.

(I have replied to you PM).

Can you attach a copy of your Gcode which exhibits the problem.

Hi Mike,

You mentioned in post #5 that your outside diameter was not completely round (my out side dia. is supposed to be 12  1/2" well in Y axis its 12  1/2 but in X its 12  3/8"). Checking your Gcode indicates that Mach3 will be following a toolpath which will produce equal dimension in both the X and Y planes and this is confirmed by the Program Limits of +/- 6.3438 (shown in the toolpath screen).

It would appear that you have a mechanical issue with your machine (backlash or flex, etc) which is causing the inaccuracy in the machined dimensions.
Perhaps ensure that the cutter you are using is truly 'sharp' and possibly reduce the feed-rate or depth of cut to reduce the loading on your machine components.

Hope this helps,

Tweakie.

General Mach Discussion / Re: Mach 3 Controlling Co2 Laser

Hi Wes709,

The M3 / M4 commands are far too slow acting so the M10Px / M11Px commands were included within Mach3 (and the M63Px / M62Px within Mach4) specially for laser use.
This thread describes my exploits and may be of interest to you;   http://www.machsupport.com/forum/index.php/topic,12444.msg248511.html#msg248511

Although I have used Mach3 for laser reproducing photographic images for many years now, for me, the relatively new software Auggie seems to have taken over.

Hi Mike,

The attachment in post #7 is not good. You need to attach your actual Gcode file (it has the file extension .tap, .nc, .txt, etc.).
