General Mach Discussion / Re: New people welcome !! Come in here and introduce your self!

Hi Chefrc,

Welcome to the forum.

You need to post your question as a new topic in the general section to get the optimum coverage and replys.

It would help if you attach your <profile>.xml file (typically Mach3Mill.xml) to your new post. Copy the .xml file from the Mach3 folder, rename it to chefrc.xml then use the Reply / Additional Options tabs to attach the file.

General Mach Discussion / Re: PWM output...

« on: March 22, 2016, 04:31:14 AM »

If it’s any help to you (or others) some while back I wrote a brief description of PWM which describes the terms / attributes of the actual signal (although it relates to lasers it is all the same really). http://hobbycncart.com/publ/cikkek/elektronikai_temaju/pwm_pulse_width_modulation/4-1-0-44

Within Mach3 you can set / adjust…
 
PRF (base frequency) from Spindle Setup. This could be adjusted to provide the best linear performance from the external digital to analogue converter used to generate the 0-10Volt signal for a VFD.

Min.PWM % from Spindle Setup. In some instances it may not be desirable to attempt to run a spindle motor too slowly. It should also be noted that 0%PWM can be the equivalent to TTL(L) and 100%PWM equivalent to TTL(H).

Min.PWM, Max.PWM and Gear Ratio from Spindle Pulleys. By careful adjustment of these figures we should be able to scale the available PWM to fit the range of spindle speeds required and also obtain a reasonably accurate RPM readout between Mach3 and a spindle tacho.

(If the two Min.PWM settings conflict is unknown (obviously one takes precedence)).

So to answer your question, yes there is an adjustment but it is very much 'trial and error'.  

My advice is just jump in and experiment.

General Mach Discussion / Re: My CNC 2030 stops following G codes

« on: March 19, 2016, 09:23:11 AM »

You perhaps need to provide some more detail about the problem and exactly what is happening.

Just some things to check…

Is your Gcode commanding the move ?
The tool is not tightly gripped in the collet / chuck and moves during use.
The Z axis is loosing steps (stalling) on the upward (+Z) moves.
Loose coupling on the Z axis motor.
Tightness or binding in the Z axis travel.

I understand that the industrial sized blenders work well.

Mach4 General Discussion / Re: Mach4 not Seeing ESS

In the Mach4Mill \ Backups folder see if you have an Machine.ini file which is dated before the bad shutdown - if you have then try using that and see if it resolves the issue.

Hi Martin,

If you have a problem which directly relates to Mach software then I am sure we could help you but Gnexlab controllers are perhaps stretching it a bit.
