Get same results when calculating vel for joint.0 inside the planner. Havent figured it out yet. I thought maybe split cycle. But have to dive deeper into it. Will do a motion test tomorrow.

Thank you. I know. My english is not so good.
an explanation with examples for an ethercat config file would be great. the beckhoff devices are not the problem. rather the servo drives.

thanks to your description I have come this far.

To the forum creators, would it be possible to add an option under Search by Keyword of Search Body Only?

For example, I am interested in the EC300 controller board. And looking for information on its use. There is a forum branch titled " Remora - ethernet NVEM / EC300 / EC500 cnc board "

See the issue?

There are a couple of sticky threads under the Ethercat section that should get you going.

What CPU does your mini pc have? It will probably work fine.

Awesome work, This is the first XPR machine running under Linuxcnc I know of. Great you cracked the Ethercat settings

Good job!

You might want to check what Joco and Rod did with holes to get your own ”true hole” stuff in the cnc.

This is incorporated into Monokrom plasma which is a qtpyvcp variant of QTplasmac. I'll see if I can find Joco's latest git for you
In the meantime, this video of mine explains the process which is based on info shared with me by a guy who worked in the Hidef manufacturing industry

There are no private messages on the forum.

Do you have other contact info, or a web site?
Data sheets, user/installation manual, company info?

For sales electrospindles for bt30/iso30/nbt30 holders with automatic tool change, water cooling and threading/positioning encoder.
The electrospindle is intended for milling machines, plotters, etc.
Power 1.5kW, 50Hz, 1500rpm, max speed 12000rpm 400hz, min speed of work 100rpm, min speed for orient 20rpm.
It is equipped with;
-Bearings front 2x7009, rear 2x7007 both P4 ABEC7
-Blowout of the spindle cone when changing the holder
-Water cooling with the option of connecting from the front or top
-Three sensors - the holder is attached, the holder is missing and the holder is pressed out
-Contactless front labyrinth seal
-Encoder for positioning/tapping
The force holding the cone is about 3500kN, and a pressure of about 7bar is needed to loosen it.
The project includes two versions, long and short.
The long version is intended for umbrella magazines, where the height of the holder and the height of the magazine and its closure must fit when changing the tool.
The short version is intended for rack magazines used, for example, in plotters.
There are also versions with or without driving bt30 stones on the front.
Encoder resolution maybe chose on order from 512ppr to 3278ppr interpolation factor 1-2-4-8-16-20-25-32-64
Electrospindle easy thread steel with M10 tap, max spindle torque is 12Nm.
Long model price is 3000Euro.
Short model price is 2800Euro.
Plus shipping from Poland.

Ok I'll read up some more... And have a look through my box of old laptops and PC's. I think I have two old laptops and a 3 year old mini pc. I also have an old htpc that I used back in the day to pirate mmm borrow movies lol.

Appreciate the help guys 

Oh one last question.
What do you mean by useless? Are we talking about the timing? Or issues running Linux?

Ah, I hadn't realised that was an option.
Thanks

Another option for reading 5V signals is spare 7I77 encoder input pins
These have the advantage of being better protected than 7I73 inputs
(to +-25V intermittant)

Got it working!!!

Attached working xml for Hypertherm XPR

Okay, I am pretty sure these are not in the ECAT driver list as I don’t remember ever seeing them, but if they are CiA402 compliant, then it should be possible to get them going.  I am positive I have seen others in the past use Lichuan, but I cannot guarantee that as I have too much LCNC info in my brain already LOL.

First, keep in mind that I can be completely wrong on all of this that I am telling you as I am not the expert on CiA402 as I don’t use it, but Tommy or Rod can check behind me to make sure I don’t get you on the wrong path.   Rod Webster is the CiA402 expert.

When you say, “but I don't yet know how to set this up”, I am not sure if you mean just the XML or the entire system, so I am going to write a little bit and just ignore me if you are verse and know what you are doing.

Since you have LCNC working, you would install the CiA402 comp file that Dominik Braun wrote.  You would use “halcompile” to install the CiA402 comp file from command line.  Next you would setup the “XML” file.  Since there is not a component written for this, you would be using the “generic” driver for your slaves in the “XML”.  There are several examples on the forum, but you basically link the pdos to your hal pins in the “XML” using the xml file you were provided as a reference.   Just search the LCNC forum for xml’s with a generic slave and you will have a starting point to work from.  

If you are not verse with ECAT but are familiar with LCNC, then launch an Axis Sim configuration and just set everything up in a “postgui” hal file and that way you can go one step at a time to get it figured out.  If it was me, I would make a simple working 3 Axis Sim configuration before trying to add the Lichuan drives.  I would just write a simple “XML” with a EK1100 as the only slave in the “XML” as it will start up without any hardware hooked up to the computer (you don’t have to own a Beckhoff EK1100 to get it working).  Once you have a working configuration and can see the LCEC pins in “HALSHOW”, then I would add the CiA402 component and make sure LCNC will still start up and work and that you can see the CiA402 comp.  Once you have the CiA402 comp installed and working, then I would choose AXIS-X/JOINT-1 to work on and add only one of the Lichuan drives and start tweaking the “XML” to get it working with Axis-X.  Once you get one of the drives working, then it’s basically the same for each axis.  I would not try adding both drives at one time as it’s much easier to go one step at a time instead of trying to get it all working in one shot.

If you are not very verse with LCNC you would need to learn the basics of how to setup your “HAL & INI” files and get a basic working configuration first before adding the ECAT section.   If you are new to this but definitely want to use ECAT, don’t get discouraged, all of us here had to start from the beginning.  Luckily I was verse with LCNC when ECAT came on the scene in 2013 as I had been using EMC2 since around 2005ish, but it would be way too confusing to start out fresh with trying to figure out both at the same time.   But since Rod Webster has gotten ECAT simplified for the install, it isn’t like the old days where you had to patch a RTAI kernel, RIP LCNC, EC-debianize, and source build LCAT driver.  Even the source build is much easier than years ago.  No workarounds or tweaks except the “golang” issue, but that is nothing compared to 2013-2015 time period with those kernel module problems.

Once again, CiA402 is rodw’s strong point, and he will be able to help you better than me as I don’t use that component.  Luckily most all of my equipment has the components already written and implemented in the driver.   If rodw can’t help, and you are desperately needing to get the machine up and running for your business, then I would contact Dominik Braun (db1981) as he wrote the CiA402 component and will be the expert on helping you.  I assume that Lichuan will work with the LCNC ECAT driver but do keep in mind that the “generic” driver will not work for all equipment.  Dominik corrected me on this years ago as I thought it would work with anything and that is not true. 

I know this doesn’t get you a working XML if that was what you were looking for, but hope it helps get you a starting point.  Unfortunately, I do not have the time to sit down and write out a “generic” XML and keep responding back and forth to get it working as it can get very involved sometimes, and it’s easier for me to do things if I have the hardware to see what is happening… but hopefully someone can help you as there are several very talented people on here all the time.  I love this community!!!

Hope it somewhat helps…
Robert


*EDIT*
After posting I did a quick search on the forum and it looks like someone else (stirra) has gotten a different Lichuan drive working.  Check his thread and look at the XML he posted.  It looks very simple compared to some of the more involved XML’s.
