Thanks spindle and gears are working now



Now it’s time to tune everything and take the first cut.

Added some new features for the gearchange yesterday, but the rain kept me from testing it.
Now I have buttons for each gear / spindle speed range.
When presse a custom MCode is executed, which stops the spindle and brings up a dialogue with the leaver positions.
Then sets the right clutch und spindle speed.

I think this will come in useful.

But what should be a quick session took me a lot longer than planned as always with me when I try to code I don‘t do it regularly and forget quite quick.

What is still missing is too write spindle speed and gear to a persistent parameter and reload it when powered on again.
Is there a best practice which parameters to use?

Next is to find a way to implement this in the post processor

OK and testing I hope I find the time for testing this evening

Thanks for reading

made sone progress on the gearbox change today.

Three problem I've got.

First the the spindle sounds like it needs new bearings,

second the parameter #<_spindle_on> os 0 even when the spindle is running, so the spindle doesn't restart after gear change

third the MCode to load the stored gear (M245) doesn't work when I put it in the startup codes. then linuxcnc errors our with M144 unknown.
M144 is a bash script and nit mapped in the INI.
When I run it in MDI later it works fine M144 is the script which brings the popup window wit the gear settings.

Fixed the spindle start by reading the hal pins. Now it works, But I didn’t make a video.
What I did film was the successful homing:



Then I removed Chuck and the mechanical clamping device.

I will clean the spindle and then start to prepare for mounting a normal chuck.

The Schunk Cuck and the clamping thing will get a a cleaning and the n will be stored till I have a need for it.

What kind of Spindle Node do you have? And where her you from?
But I am not sure If I will sell it.
Now that I know how to mount it and if I make some tools mounting and dismounting won’t take that long.
It is a nice three jaw chuck and I have a lot of jaws for it. 
But I font think I will ever need the automatic clamping it was fun to get it running and it nice for a Job shop but for me it is more or less useless, cause I don’t think I will make more thank three same parts in a row.
But I would would be really tempted trade it for a 250mm there jaw chuck with two piece jaws cable of 2250 rpm
 

It’s not really near by, good look on the search.

put the tool mount back on the lathe:

then I took the first cut on the machine:

used the hand wheels to tale the first gut of the face plate

After adjusting the spindle speed the surface finish got better. And I should close the cable ways and make me son wipers.
so here it is ready for drilling the faceplate for the new chuck

looks a lit lost, bu should be enough for most of what's coming next time

 

It is a cool feeling to make a part on the machine for the first time. You are way ahead of me
Mark.
