Can you zip and attach the Gcode file for the part that shows this error. Use the Reply tab and Additional Options to attach the file to your reply.

I am pleased that you have found the problem.

Loctite threadlocker (or similar) comes to mind.

Why the heck would they lock the button from inside the box?

That is just weird but who knows just what they are thinking ??

Excellent information Woolyacresfarms.

I think Samuel listened to what you said but perhaps, like me, he did not fully understand that the button is locked from within.

Lets hope this cures the problem and that his CNC now leaps into life.

Use the contact form to explain the situation to Licensing, I am sure they will be able to help you resolve the problem. http://www.machsupport.com/contact-us/

You also need to check the address of your LPT parallel port (in Device Manager) and make sure that is the Port #1 address you have entered in Mach3 (usually 0378).

where do i find general section to  have a new  topic

Sorry, I should have been more specific  General Mach Discussion just select New Topic.

Excellent new video Samuel.

When everything is powered-up do your stepper motors 'lock' into position or are the free to rotate by hand ?

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.
