Okey this is new for me ... why is there the timing setup or else ? Can you explain us more about your knowledge please?

After changes in the master version it does not start, error as in the screenshot. In the compiled version some configurations work and some do not, but maybe it is only my problem. 

I am sending a corrected ui file of qtdragon hd vertical.


I do not know if the new sim directory for vert. I have tested almost all ini configurations and they work with the vert.ui version, so it is probably not necessary.

Hmm I worked it out, I don't really want to talk about it but I was trying to add outputs on pins that were already assigned to inputs, and strangely enough that didn't work...been a long weekend 

Thanks for the hint.
I will try to find out how these pins can be set TRUE when starting Linuxcnc.
Ok, the y-axis I do not need for the lathe, but X and Z. So some homework to do.

Thanks PCW

Thank you. The spindle is now working.

I really appreciate the help.

Thank you,

I've just created this topic:
"homing with Phase Z encoder on MESA 7i96s".

Thanks tuxcnc, ya I couldn't get it to work. The final IC's I used was a 26ls32 to single end the differational signal. Into a 74htc14 to boost the signal to 5v. And then into a uln2003 IC to pull down the 12v denford pulses. I was getting a lot of noise. I tried pulling up/down resistors and capacitors to try and negate it. But didnt work. These dm566 drivers seem to work fine with the ec500. I'll have to do some more testing.

Bonjour,
on me demande créer un nouveau "typic" concernant le sujet ci dessus . je sais pas du tout comment cela fonctionne. Le crée en français, car je suis français. Quelqu'un peut il m'aider ?

Merci

I don't understand, I have to create another subject.

Linuxcnc servo cycle is not synchronized with the ethercat cycle. That adds an extra cycle delay.
 

Hi Russell,
please add your config

Cheers Olli

Tengo que cambiar algo en pncconf

(my first post here)

I was given a Grizzly G1006 with a CNC kit.  The previous owner bought the mill new, and did the CNC conversion himself.  And he built the servo control box himself, including the power supply. And he built the pendant control box.  And he built the pendant.

Of course, I didn't know how any of this worked, but I knew I had all the cabling, and the computer.  So I plugged in the things that were obvious.  Then I had to reverse engineer the purpose of the cables that were not obvious. 

It was controlled from a 2003 era computer running Windows 10, and Mach 3.  The parallel port sent commands to a PMDX-122, which sent steps to three Geckodrive G320s. 

Anyway... I got it to move.

Now I'm converting it to LinuxCNC.

I have a Mesa 7i96s, that will be replacing the PMDX-122. I have a USB game controller that will be replacing the pendant.
I'm going to try to keep his original servo control box, with his bespoke power supply.

USDigital encoders (250 step)

Thanks to all of you who are building and supporting LinuxCNC. I have found many resources to help get me started.   I'm sure I'll have some questions, and probably a build thread. 

Just wanted to say hi.

I originally had this running on a cheap eBay BOB using the denford drivers. When I switched over to the EC500 I could not get the driver working correctly with the EC500. After many attempts with different IC and board configurations I gave up trying to use the denford drivers and bought DM556T drivers. Still on the denfords motors.
 

The EC500 has strange "differential" outputs 3.3 V.
I don't know any motor controller that has such inputs, but some 5-24 V work.
If problem, I use PC817 optocouplers without any resistors.
They have poor parameters, but only these want to work for me ...

The below is what I use for testing and messing around with Linuxcnc. I'm a little biased towards Lenvo, I have a couple of ThinkPads, 2 ThinkCentres and a ThinkStation. Never had an issue, my T530 ThinkPad is my daily driver.

You'll need a parallel motherboard port cable (otherwise you can't enable the PP in the BIOS) www.ebay.com/itm/256520010767

A small SSD is not a bad idea as well 128GB is enough.

You wont need to do much to your configs, except the small diffs from 2.7 to 2.9.
