Spanish / Re: El mach3 me corta pero no respeta las medidas
« on: April 20, 2016, 07:18:01 AM »
buen día. me construí un router cnc y me quedo muy bien compre los kits que venden en china y todo funciona bien abro el control manual con el tabulador y corre bien pero cuando mando a trabajar con un archivo realizado con artam me lo pone bien el mach pero lo hace mucho mas grande como al 300% mas. alguien sabe a que se debe? ya le menie los controles de motores de configuración del mach y nada. en el mnual de la interface dice que debe estar los steps per en 2000, velocity 120, aceleration 4 y los step pulse en 5y asi lo tengo , ya le baje la velocity y nada, gracias por su ayuda

If Mach3 is set-up in millimeters and your CAD/CAM software produces the Gcode set for Inches then that could be the problem ??
Inserting G20 at the start of your Gcode file may resolve the issue.

Google Translate...
Si Mach3 es puesta a punto en milímetros y su software CAD / CAM produce el Código G ajustado para pulgadas entonces que podría ser el problema ??
Inserción del G-20 en el inicio de su archivo de código G puede resolver el problema.

Your Gcode runs (using your .xml settings) just fine here and without any error. You appear to be using a rather old version of Mach3 - I am not certain that updating to a later version would make any difference but it is worth a try (use version R3.043.062 rather than .066).

Please attach <your profile> .xml file -  the one from the Mach3 folder (typically Mach3Mill.xml). Copy and rename it to Solosys.xml and use the Reply tab and Additional Options to attach to your post. This file contains your machine settings and may throw some light on the problem.

General Mach Discussion / Re: Z Acceleration

One test you could perhaps do is temporarily half your Z axis Velocity and Acceleration in Motor Tuning then see if the same issue persists ?

Hi Vince,

Welcome to the forum.

The fact that it used to work good but now it doesn’t is a bit suspicious.

From what you say it is my understanding that…

If you zero the Z axis DRO and your dial test indicator then MDI a command Z 0.100 the Z axis moves ~ 0.1125 but the Z axis DRO now shows 0.1000 ?

It is unusual for a Z axis to move further than commanded on the way up (assuming there is not a counter-balance system in use).

Try the same thing on the way down. Zero everything then MDI  Z -0.100. Do you still get approx. the same error between the dial test indicator and DRO ?

General Mach Discussion / Re: Tool moving to random coordinates

Thank you I should familiarize myself with the manual properly

I don't think you can expect to learn it all (there are parts I still don't fully understand) but the combination of manual and hands-on experience seems to win out in the end.  ;)

I can 100% confirm that when entering g0 then the axis and a number it moves to that location in work coordinates. So if you zero x and then enter g0x20 it moves 20mm in axis x and if you enter the same again it doesnt move at all. Is this abnormal?

That is exactly as is should be when working in Absolute mode. The X axis is already at X20 so no movement is necessary.

On the other hand, if you were working in Incremental mode then the X axis would move another 20mm.

This is all explained, much better than I can, in the Mach 3 Manual. http://www.machsupport.com/help-learning/product-manuals/

IOW how do you prevent this from happening? 

I am not sure you can actually prevent it from happening but on occasions when the .xml is being updated in 'real-time' then making a number of changes to the configuration in quick succession can often cause the problem.

On the other hand, when the .xml is only updated at program close it is very rare for a corrupt .xml to be created.
