General Mach Discussion / Toolpath representation of drill operation

« on: April 02, 2010, 04:00:36 PM »

Hi,

Im currently writing a hole wizard for my screenset that allows to create hole patterns.

I have notices that the toolpath is not very clear when doing just drilling operations. it just shows the vertical feeds and the rapid moves, but it is not easy to spot the drill position that way.

Is there any way to make the toolpath windows show something like a dotted circle at the bottom of the drill or anything that can help represent better the drill toolpath, specially when viewing from the top?

Thanks

SmoothStepper USB / Re: Problem when stopping execution

« on: April 02, 2010, 02:06:40 PM »

I tried that, but even with a higher frequency the feedhold will complete its queue or at least the current move, that may be long.
Why cant it just deacccelerate the current move as fast as possible stopping to a know state and then on resume doing the whole move again if neccesary?

Thanks for your answer Hood.

If that is the case, maybe thats not the kind of stop I need, neither feedhold that is far too slow because it empties its queue before stopping.

Can a stop be implemented that deaccelerates the current move in a fast but controlled way?

Doesnt mach know at every time the pulse count it has sent to a motor or there is some hardware limitation I dont know?

Thanks

G-Code, CAD, and CAM discussions / Re: Load Mach3 with mastercam G code

« on: April 01, 2010, 09:42:26 PM »

Youre welcome Mario,

The postprocessor is a file related to the CAM that tells it the way it must generate GCode to be usable in your machine. In your case, the Fanuc postprocessor is compatible with Mach so it will interpret it ok (at least most of the code)
In this section
http://www.machsupport.com/posts.php
there are postprocessors written for some of the most popular CAMs to work with Mach. I have never tested the mastercam postpros, but maybe you can give them a try when you have time.

By the way, where are you from?

Hi,

When I load your code, mach outputs the following error in the status line:

Cannot use two gcodes that both use axis values.

It references the following line:

N644 G91 G0 G28 Z0.

If you remove G0 from that line, the code loads fine.
I cant check any further if the code does what it should because I dont know the part.
What mastercam post processor are you using?

I dont use mastercam but I have seen in the download section post processors for it.

General Mach Discussion / PWM to RS485 spindle speed interface

« on: April 01, 2010, 12:49:38 AM »

If anyone is interested, I wrote an AVR program for a ATMEGA48 mcu to read the Smoothstepper spindle speed PWM and convert it to my VFDs RS485 protocol.
It can read from 0 to max rpm with 50rpm increment.
It can easily be modified to fit other VFDs that accept rs485.

If you want it mail me to pamafe@gmail.com and I will send schematics and code.

Regards

SmoothStepper USB / Problem when stopping execution

« on: April 01, 2010, 12:33:32 AM »

I had this problem many times. I would like to know if everybody has the same issue or am I doing something wrong.
I have a smoothstepper running my router.

Lets say that I have my machine references and zeroed and I start the program execution. I notice that something is going wrong and cant wait for feedhold to compelte so I push STOP (not e-stop button, just stop) in the middle of a move. The machine stops immediately, but all references are lost. My zero position is lost, and machine coordinates are no longer valid. I can even trip into a limit switch if i jog.

My guess is that this happens because the stop tells the SSto halt immediately, but SS does not communicate back the exact position where it stopped so Mach does not know wjere it stopped.

Is this a known issue? Can it be solved?

Thanks

Hi Mario

Can you please post a piece of code of what your postprocessor is outputting and maybe a description or a screenshot of what you expect it to do?

Flash Screens / My flash screenset with touch and wizards

« on: March 31, 2010, 11:05:16 PM »

Hi,

This is the screenset Im currently developing for my router. It has some wizards integrated because I preffer to program in Actionscript than VBScript.
The actual screenset is 1280x1024. There are many features im planning to add. Im currently working on the teach/mdi screen
Please fell free to make any suggestions and critics.

Thanks
Pablo
