Hi All I finished making a probe, tried it out using Tcnc 3.25. But it does not work!!!!!! Used fkeybit to check it out, works fine, set config, pin 14, active...
Many thanks for all the input - from what you have all said I suspect the problem may well be due cutting forces moving the head so I am going to try the...
Hi Richard, Assuming the aluminium is thick enough, I would go for a slightly oversize hole (+0.01mm) and use a bearing grade Loctite - probably with an...
And I cannot seem to "load" it to run. I bring up the run from file, but everytime I select my file that I created, it keeps loading the *.*CNC or MIDI and...

Richard, to be honest with you I have been in the machine shop business .... for many years. I have never cut a circular pocket with the intention of holding...
hello all, i am new to turbocnc and have a few questions.i am using only 1 axis. at startup, the axis is losing last position, example, at shutdown when it...
You might also want to consider "easing" into the hole by letting Z drive down from above the part to the final cut depth as X and Y are tracing the path. Thiw...

Hi, I don't often see end mills suitable for plunging in my tool catalogues; they are dearer than the standard end mill and more difficult to sharpen too. I...
Using the search function with MSCs online catalog it turns up 1250 centercutting end mills with a 3/8" shank on them and 5952 centercutting endmills all...
First of all may I say a big thank you to everyone for your help - I subscribe to several Yahoo groups and this has been the most friendly and helpful by far! ...
Hi Jerry, That's what I've been thinking of. I'm wondering if a G02/G03 type of block could be "expanded" to allow multiple full circles and a Z excursion for...
There are cutting edges in the center of end mills. All 2 flute end mills are center cuttings and 4 flute end mills that specifically specify it are center...
Tony, I went to Port Monitor and it shows Pins 3 & 5 Green. 2,4,6,7,8,9, 18 thru 25 as Brown. If I am to toggle something please tell me how and then how to...
I think this may be a pond thing. In the US, end mills are either center-cutting or not center-cutting, but they're all end mills. If I'm not mistaken, in...
I would also try to change backlash compensation one axis at a time and see what shape it cuts. Similarly, try different spots on the bed and compare shapes....
Its been a long time since I've done anything like this but can't a spread sheet be set up to walk a pocket out in steps and give you the xyzij numbers you...

I am trying to get a program of Gcode that I created to run. I have tried to run from file and to run in the memory. I cannot get it to load. If I go to the...
Tony, thanks that got me half way there! I did get it to step, voltage readings all over the place between .75 and 4.90 with several in the one and three volt...
John: Your raedings should be stable across multiple changes of state of the I/O pin. Every high should have the same voltage, as should every low. If your...
