General Mach Discussion / Re: Mach Just Stops

Hi Dave,

I am glad you have got it sorted.

In an ideal world you should investigate and resolve the noise problem rather than just rely on the de-bounce but 500 is not over the top and many use a higher figure than this.

General Mach Discussion / Re: Shopbot with Mach3 homing issues

John,

I don't actually use the "ref all home button" but this is a VB button which means that it's function is user configurable (Operator / Edit Button Script / click on flashing button). There is a chance that it is configured incorrectly for your setup of using a slaved axis.

Not much help really but that's all I know about it.

John,

We all like to help and provide support on this forum but we do not in any way condone software piracy.

No offence intended but I am a bit concerned that you have one of the "Ivan..... " licensed versions of Mach3 - perhaps you would clarify this situation please.

If your motors are not getting hot then I would look for an intermittent or poor connection between the board and motors (a sudden open circuit here can destroy the driver chip) connectors, soldered joints etc.

General Mach Discussion / Re: Problem with "Y" axis

« on: April 15, 2011, 12:26:11 PM »

I forgot to mention that the Y axis negative move (when you press Goto 0) is related to the actual GCode being offset from the X,0 Y,0 position.

Hope this helps.

General Mach Discussion / Re: x axis moves one direction

« on: April 15, 2011, 12:16:13 PM »

Each axis moves as the result of step and direction signals.
If 100 step pulses are sent and the direction signal is low then the axis will move in one direction - if 100 pulses are sent and the direction signal is high then the axis will move in the opposite direction. If the direction signal is not connected then the axis can only move in one direction.

You need to check that you have the X axis direction signal wire connected correctly and configured correctly within Mach (correct port and pin etc)

Mr Motion,

Having run your GCode it appears OK so what you see in the Mach toolpath window is the output information that Mach is sending but for some reason your machine is not responding correctly.
Do you have problems running other GCode examples or just this one ?

Merv,

Your driver board sets the current that is applied to the steppers and  it sounds like it is set too high. Do the motors get hot to the touch during operation ?

Michael,

Not much help really but the best thing you could do is "try it and see".
