General Mach Discussion / Re: Tool Change

Sorry for the very late reply, but I was not able the test any sooner.
But unfortunately it did not work. I also realized that all my subs already end with a "G00 Z25" to bring the tool to a safe height.
So the last movement before a tool change has always been a G00.
But anyway, thanks for helping.

That sounds logical. This should remember Mach3 that the last move before toolchange was at G00 speed.
I give it a try.
Thanks,

Wilfried.

Hello,

This is the simple brain I use to control the X-axis.
Hope this helps.
Best regards

Wilfried.

Hello Graig,

I fear you are thinking along the wrong track. The hardware of the pendant is OK.
That is proven by the fact that the diagnostic Window of Mach3 shows the correct LED's lighting up when the axis-knob is turned.
The problem obvious is the handling of these settings within the "brains" of Mach3. There the internal variable representing the axis to move gets out of sync with the input status of the relevant oem#  pin.
Best regards,

BTW: The relevant part of the ProPendant consists of a 5 way rotary switch. In each of the positions 2 to 5, the relevant contact is connected to common (0V).
In Mac3 the oem#1,2,3,4  Pins are set to "Enabled" and "Active low". That's all.

Helo Craig,

I have a "Propendant", which is the most ordinary pendent you can imagine.  Just the case, the switches and the wires. It is to be connected to the LPT2.
It works OK most of the time, but sometimes the internal Mach3 settings for which axis is to be controlled, get out of phase with the settings of the axis knob on the pendant.
The pendant itself seems OK, as can be seen from the diagnostic screen.
I know there are many other pendants available, but like to know what is going wrong here.
Best regards

Wilfried.

General Mach Discussion / Mach3 Pendant
« on: March 07, 2018, 09:30:43 AM »
Hello everyone,

Some time ago I installed a LPT2 card and a pendant in Mach3. The Usual stuff. All seemed to work fine.
Then I found out that some times (if not often) the wrong axis is moving when turning the MPG.
Using the Diagnostics window in Mach3, I found out that the pin status is correct and matches the setting of the X,Y,Z pendant knob.
I tried debouncing the X,Y,Z  LPT2 input contacts, but to no avail.
Has anyone any idea what causes this phenomenon and how I can solve it ?
Regards,

wilfoude

General Mach Discussion / Tool Change
« on: March 04, 2018, 05:03:23 AM »
Whenever I move the spindle on my CNC-Router  to a convenient place to perform a tool change, it will return to the place where it came from in a  very slow speed.
In fact the feed speed that has last been been programmed before the tool change.
In case of drilling holes, that would in my case be 50 mm/min  (I always do the drilling very slow).
N.B. I use stanfard code fragments;
e.g. for a  tool change:
-
N1000 M06 D04 T04  (change to 4 mm in D04)
N1010 S3000 F3000
-
How do I make the spindle return more quickly ?
regards,

General Mach Discussion / Re: Skipped code
« on: December 30, 2015, 07:18:21 AM »
Hello BR549,
Sorry for this late reaction. But we had a Christmas to celebrate here and I was forbidden to sneak to my workshop.
I have the code attached for the panel I had to produce. It will show a panel with 3 rows of circuit breakers, 4 round clocks and some other stuff. In this version of the code, 2 of the clocks, which are visible on the screen, are not centre-drilled. This happened also to a number of circuit breakers in a previous version. In that version all circuit breakers and clocks were called with the same sub. In the current version I call the subs with the L-option and that made it work normally. Except for the centre-drill of 2 of the clocks

General Mach Discussion / Skipped code
« on: December 20, 2015, 02:48:37 PM »
Hello everyone,
I still have trouble finding the right way to post a question. I hope this is the correct way and someone is able to help.

I'm pressed to produce some instrument panels for gliders and a boat. Because many objects on the panels (circuit breakers, meters) are repeatedly used, I use subroutines for these items. This always worked fine. To my dismay I'm now confronted with the fact that many of the objects are skipped. They are drawn on the screen, but are not executed when running the program. I have had this before with 1 or 2 objects, but not so bad as now.
Is this a bug in Mach3 ?  Am I  the only one experiencing this phenomenon? I already had to find out the hard way that tool compensation does not work in subs. Maybe there are more pitfalls ?
N.B. Im sure the code is correct. I's simply the same line that is repeated with different coordinates.
Best regards,
Wilfried

I apolize for using this place to put a new question, but I don't know how and where to start a new topic This one seemed reasonable close.
I hope someobe can help.
I use MACH3 for some time now, and all works fine. Recently I decided to add a MPG. So I bought a very simple one, just the MPG and some switches and added a Sweex ECP-compatible PCI-LPT-card to the PC. But I don't get the thing working. It looks like the port does not behave like an input, despite the fact that the BIOS is set for ECP and in Mach3 at "Config=>Ports and Pins" the pins 2-0 on LPT2 are set for input. The other inputs on the LPT2 seem t work (pin 10, 11,12,13), just not the main data pins 2-9. What have I overlooked ?
