VB and the development of wizards / Re: PoppaBear Question SCott??

« on: October 04, 2013, 07:33:57 PM »

HIYA Roger. The problem with the "write to file" is that mach3 does NOT issue error codes when that occurs. So to the program that processes the points file it cannot tell the difference between an actual trip or an end of motion value. That leaves the points file corrupted. NO point is much better than a corrupt value as far as the point cloud is concerned.

Yes IF you are doing the write to file VIA CB you can do a compare BUT that really SLOWS the process down. and really all you would do is NOT write the value if it is the same as teh end of motion value.

Hiya GER. I will have to check with Scott to see IF he has redone the Plugin to the FIXED version. Here I use the older Plugin and a macro pump to make it all work. Scott was going to include the macro code into the plugin so it would work with all current version of MACh3.

So far I have NOT been able to fool it and I have really tried(;-).

General Mach Discussion / Re: Looking for the Moron's guide to CnC

« on: October 04, 2013, 11:16:41 AM »

As there are as many WAYS to do CNC as there are hairs on your head I do not know of any single source for CNC for Dummys.

Most have to learn it as they go BASED on HOW they are designing it to work AND what controller they are running.

A total CNC concept has a VERY steep learning curve IF you are starting from scratch. Studying up you can learn some general point about the process but the final leaning curve will be based on the approach you started with.  Each case can be unique.

NOW even iof you get as far as the Machine is done and working correctly the learning starts OVER again with learning the CNC processes.

Cad, you have to learn to draw the object in a form the CAM understands.

Cam , converts the drawing into machine code(gcode).

Gcode, runs the machine and you NEED to understand WHAT the machine is doing to know IF it is wrong(;-) or how to correct it.

Hand coding, for those simple projects that you need  without going back to CAD/CAM.

NOW each one of these process can be different depending on which package you started with. Cads can be different , Cams can be different AND Gcodes can be different with the various offerings.

YES please don't do it in that instance either. (;-)

BUT actually we have it running just fine now, it took a while to work around the quirks.

NOW IF we could get the "Write to file" corrected so it did NOT write IF the G31 did not trip by the end of motion(endpoint).

I believe that the reason you see what you see is that you have the pullback setting larger than your total depth to drill so it only retracts to the R level instead of the peck value.

To set the pullback value fro G73

General config, pins and ports, Mill options.

AND you may have to learn the secret handshake to make the setting change.

General Mach Discussion / Re: output all settings as text

« on: October 03, 2013, 01:29:33 AM »

At the current time there is no way to do what you want other than cut and paste all the config pages.

Klaus IS working on a update to his XML reader than should do what you need. IF I understand what it is he is doing you will be able to do a printout that describes each setting as it appears in mach3.

BUT that is a LOT of printout to maintain(many pages). Keeping a copy of the XML will do the same thing as far as retaining all the config settings.

Just a thought, (;-) TP

Just tested the G73 here and it works like it is suppose to.

Please explain what you think it should be doing  based on your example code.

SO what do you have the G73 pullback value set at ??

Sounds like you have the M3 and M5 SWITCHED as far as pins/ports are concerned.

The g12/G13 is an orphin Gcode very few people even use it as it does NOT conform to nomal usage. You would be better off just using G2/G3 and programing a circle.

Precision is SET by the steps per unit and the courseness of your leadscrews.  Based on your setup mach3 will make an exact step OR the next closest step to get to the position. Some setups do not allow full step precision as the next step would take you PAST the next position so it has to stop short to prevent gouging.

So you setup YOUR machine according to the mechanics of the drives.   Feedscrew pitch X reduction (if any) X microsteps of the drive = steps per unit.

OK I just tried YOUR code and it moved to exactly where the code stated.
