Re: the Z-180 after homing:
Seems your config homes at joint position 200 rather than 0, which is new.

i.e. Z axis travel of 1065mm and home at zero. But after starting and homing z is automatically at -180mm.

Could you attach the ini file? (I notice that you have changed the z-offset to 0)



Re: Toolchange position.
I see this now. I'll need to investigate.

Following this but it seems the same problem has come up again.
Might I be missing a crucial step?
Everything is working as intended, until the encoder come into play...

FYI: Encoders Scale is (1000PPR*4mm/rev)/4=1000

Great! You got it working! I was thinking maybe you had copied files from a CD or something so they could not be written to. But I was in the right area!

I installed an ASRock N100DC-ITX and am very happy with it. It already includes a processor and has the advantage of running on a laptop power supply.
Recommendation from talla83:

I can confirm the stated latency times.

i need to set some axis to non Zero values to prevent the kinematics failure,
try to set the 4. and 5. joint to 0.01 and check if the error is gone

Mostly it's a "bang for buck" issue.

I can argue for & against it.

what do you all have against a raspberry pi?
it works well and there are all kinds of cases for it.

Thanks Wischi, now works like it should.
I had not thought to go back to the ini file ! Getting old !

Not sure what you meant by "popup in the right hand corner".
My install starts clean without a pop-up.

I do get a warning when the code reaches the tool change that the bell is not connected (it isn't).
I will soon get a bell, or de-select it.

Hey there, JB-Motoring,

how did you manage to get the encoders in working order? Did you end up buying 5 IBV boxes? From past experiences EXE ones work better, but they are rather expensive. Or did you somehow directly connect them to the 7i97T card?

I have a similar machine I am looking to retrofit (DMU 50M, same encoders) and am wondering what hardware to buy.

Thanks.

The more I think about this, It could very well be the PWM conversion onboard the EC500 is just to slow. It may not be able to keep up with the CSS speed adjustments. Any idea how to set the EC500 to output PWM instead and I'll hook up a PWM to Analog conversion board to test it. I know in the documentation you can switch it using Mach3 software.

Reading Work Coordinates When Loading a New NGC File  

When loading a new `.ngc` file in LinuxCNC, is it possible to read the work coordinates at that stage? Since the G-code has not been executed yet, the work coordinates might not be applied.  

Would it be possible to create a custom button, similar to "WCS Sync," that reads the `.ngc` file and sends commands like `G55` to MDI?  

Has anyone implemented something similar, or does LinuxCNC provide a built-in way to achieve this? Any insights or suggestions would be greatly appreciated.

Thanks!

I had been using it without much thought, but it seems better to remove G43H0 G54.
The tool length offset is unintentionally canceled, and the work coordinate system switches."

Postgui file looks fine.

You can remove this block from the gm.hal:

It is not connected to anything but it will remove the popup in the right hand corner when starting linuxcnc. You don't need it anymore because you use the gmoccapy tool change dialog.

Check your ini config file if it includes this line under [HAL], if not add it:

I recommend you keep all original brusheless motors, but perhaps you don't care about preserving old motors enough to spend the time.

Try to sell them, they may be worth more than their scrap value.

(Not sure what scarp metal prices are like where you are)

I'm assuming the closer you are to China (and Vietnam, Thailand, etc.), the higher the value of E-waste because the shipping to the reccling center in Asia is cheaper.

Hi Langdons,

I'd like to reuse them, but I haven't been able to find any successful examples of this online so far.

I can find Delta drives in the right voltage and they sell all their encoders as spare parts. I guess it's a matter of deciphering the spare part codes to match the right drives and figuring out how to adapt them. There is space to mount on the back of the motors where the Heidenhain encoders are.

Anyone done this?
