Re: [Emc-users] cnc axis "Touch Off"

Hello, this is probably a rookie question, but sometime when I do a "Touch Off",  the Z-position indeed becomes 0,  but the X and Y are not.   Then in teh axis program, it will still go to the "first" spot where it needs to start milling, and in the  drawing it fllows the correct

Here is a video of someone cutting a helical gear using LinuxCNC on a 4-axis mill with all of the axis set square. He used hand-coded g-code. It is also possible but much slower to use a ball-end mill on a normal 4-axis milling machine. https://youtu.be/eh6UgCSoZec?t=68 -- Chris Albertson

[Emc-users] CNC Remote

Hi, We are a tiny french company working with CNC machines managed by … LinuxCNC of course ! ;-) For our internal needs, we developed an iOS app to be able to control basic LinuxCNC functions remotely from iPhones and iPads. Recently, We decided to make it available to others and it is now

[Emc-users] CNC Fest in Houston

John, Are you going to the fest in Houston? I am looking for another driver. My wife is dithering on going, and I am guessing she probably won't want to leave nobody keeping an eye on the kids for that long. It appears to be about 13 hours from St. Louis. That's doable in one shot for two

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Hi to all. Just to show an amazing sewing technology . Robot Sewing Machine https://www.youtube.com/watch?v=_i4cfQGe8fY I do believe that in this case a synchronicity between robot axis and needle position is needed. Regards Alex On Fri, Aug 29, 2014 at 6:04 PM, alex chiosso achio...@gmail.com

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Hio Philipp , you got it! The exact lenght for each stitch is a must. So the example of G code that you kindly gave me is what should be done (I mean it is a starting point) . Actually (I was this morning to the sewing machine customer) with the intergration I did the result is good enough for

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Hi Gregg. Yes this device should be fast enough. The problem is how to integrate it with the current machanic structure. You have to consider also that the operator need the right space where to lay the fabric (i.e. the jacket). Regards Alex On Fri, Aug 29, 2014 at 5:29 PM, alex chiosso

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Hi Gregg . The locking of the steps is fine in case of safety. The X-Y axis have always to complete the stitch lenght movement, otherwhise you obtain a non costant stitch lenght. Hi Michal Thanks for the infos. A couple of questions more. How do you synchronize the needle movement with the X-Y

This sort of thing should be fast and accurate enough for moving the sewing machine platform in between stitches. http://hackaday.com/2014/08/28/800-inches-per-minute-at-0-00025-resolution/ --- This email is free from viruses and malware because avast! Antivirus protection is active.

[Emc-users] CNC Sewing/Embroidery/Quilting Machine

Hi to all. A few years ago I made the electrical/electronic/software integration of such a kind of machine. An industrial grade sewing machine adapted/converted in the way to automatically sew labels on clothes (jackets mainly) with a programmable but fixed path . Programmable because the operator

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Alex, I'd use Linuxcnc to build it. You can use steppers to control the needle motor and looper in open loop. Your G-code could be written to just stop X and Y when the needle is below the surface of the fabric. On 08/27/2014 10:21 AM, alex chiosso wrote: The application can appear trivial

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Alex, We started using Linuxcnc to control all sorts automation in the lab. Breaking down the steps to stitch: Move X,Y to start of the stitch (with Z at max height) Move Z down to min. (needle to lowest point) Raise needle Start Loop (spin looper motor) Finish Loop Needle to max height

Re: [Emc-users] CNC Sewing/Embroidery/Quilting Machine

Bari , thank you for your reply. How is working a sewing machine for me it is clear (I really did the application I described). I read into a Brother industrial sewing machine user/maintenance manual and their electronic control manage encoders for the motors. On Wed, Aug 27, 2014 at 6:42 PM,
