[Emc-users] Setting tool heights

I've been watching the Tormach Path Pilot videos on tool height and offsets. https://youtu.be/BoIB_Fatt44 https://youtu.be/2EIQo8g4RVQ Very similar to what is available in MACH. Is there a graphical interface for AXIS that lets you enter in the tool height values or use the machine

Re: [Emc-users] Setting tool heights

In the manual page (F3) enter the tool Z position (e.g 0 if you are using the paper trick) and press the tool offset button. I personally don't like using paper. It's easy to make a mistake and damage your tool/work. I prefer to use a round bar of a known diameter (e.g the shank of an old tool)

No I don't but you might find this interesting. It was in an email I got two days ago. The software is downloadable; https://www.st.com/en/evaluation-tools/steval-eth001v1.html?ecmp=tt21493_gl_enews_jun2021&cid=stmDM44500&bid=438016236&uid=mrX5prLpL0WLPr+vcjBGHEiEOnoACPSG9a4XfANkxEI= On Sun, 11

Re: [Emc-users] Ethercat returning message disappear

At $294 (out of stock too) that eval board is way more expensive than a STMBL kit which also can drive a motor with a much higher power supply voltage. I'm surprised that ST charges so much for something like that. You'd think with their size they could produce demo boards for really cheap, peo

Re: [Emc-users] Ethercat returning message disappear

STM does sell some subsidized boards. These are dirt cheap because they want you to develop a product using the parts. My favorite is the Nucleo series This one sells for about $13. st.com/en/evaluation-tools/nucleo-f411re.html It make

[Emc-users] 'automatically' go halfway between 2 points

Hello, in linuxcnc,  is there an easy/automated way to get halfway between two points?   (Fort example, you'd touch off somewhere, move to some coordinate (x, y)  (or even (x, y, z)) and go inbetween right to the the middle of where you touched off and where the spindle is now? thanks, R

I still have my Shumatech DRO on my mill. I touch one side and zero the axis. I then move across and jog until the LED goes on. Then FCN 1 and the axis letter button. At that point the axis changes to minus halfway between where I just touched off and the original 0 point. I move to make the

Re: [Emc-users] 'automatically' go halfway between 2 points

Hi John, I have seen videos about these electronic "add on" DROs that is actually why I am asking.   It would be incredibly helpful finding the center of circles (aka holes), or squares, the center of stock etc etc. That's why I wondered if there is something like that in linuxcnc.   (Mayb

Re: [Emc-users] 'automatically' go halfway between 2 points

Hi Ron, I guess you could do it with a custom component in HAL. You can link a physical button to set the points and then compute the center point. You should need a reset button and some other functionalities too I guess, but I think it's perfectly doable. Also you could show the output with pyvc

Re: [Emc-users] 'automatically' go halfway between 2 points

Essentially the process involves two touch off operations. First one side until an LED comes on or even better the probe input goes active. At that point touch off so the axis is set to 0. Then you move in the opposite direction until the probe (or LED) goes active. Divide that axis value by

Re: [Emc-users] 'automatically' go halfway between 2 points

I've been watching the Tormach Path Pilot videos and there's a lot of information in the LCNC side of things for setting tool height etc. There are a number of G-Code macros that can find edges. John > -Original Message- > From: R C [mailto:cjv...@gmail.com] > Sent: July-11-21 9:58 PM

Hi Leonardo, That was actually what I was looking for, a button "like that", and wondered if I just didn't see/find it. Yeah I can see some "convenient" functionality in that,  but being able to go "half way" between two points, even with some iteration would help, to get that started (It

Re: [Emc-users] 'automatically' go halfway between 2 points

Here are your 3 points. As a math wiz you can see that if you draw a perpendicular line from each pair of points they all intersect in the middle. The third angle is the one I can create graphically and from that the length for the XY of the center but you might be able to explain the math a b

Re: [Emc-users] 'automatically' go halfway between 2 points

correct, If you draw 2, different, triangles like that, with their corners on a circle, their hypotenuses intersect in the center of that circle. also the middle of these hypotenuses, of each triangle, would be the center, hence, that is why I was interested in finding  the "half way point" of
