Minor update, had a bit of a play...

Now running 10x microstepping, 4.92m/m (about 200ipm for those so inclined) and 375mm/s^2 acceleration. 32 and a bit khz, and no stalls or obvious mis-steps...

Hi folks..

Thanks for the replies, lots of good info to follow up on...

Alan: To answer your question, I'm currently running 320 steps/mm Top speed of only 3.3m/minute (55mm/s) = 17.6khz. ...

Ay, saw those on the cnc4pc site, but a bit shy of converting to mach3 as I have 200+ gcode files for products I really don't want to have to revisit

Not averse to suing mach3 itself given it's...

Just replying to myself :-)

The other question is, should I just buy high spec motherboards and stuff a PCI parallel port in I suppose, I imagine they will be available for some time to come...

Hi folks...

I've got a machine (quickCNC K6100 + CNC4PC C11 BOB + Linuxcnc 2.5) that is running fine, but I recently had a motherboard die, and had a some problems with one Asus board that had...

OK... I'll have to look that up here, I've seen acrylic laminated with wood look finishes, but not stone, it looks cool.

Great finishing job, well done.

Cheers, Chris H.

What's the material? Looks like stone but assume it isn't?

Hi Rocket...

My 6100 is still going strong. I've made a serious pile of MDF dust, cut a lot of plastic, some Alloy plate and even routed some channels in some copper heatsinks which was...

That would go for most of us who have technical hobbies.

I used to work in a large engineering/technical environment which meant that there were folks I could talk to about all manner of things...

Hi...

Can as ask what it says? Arabic text looks amazing as a design/pattern but I'm not sure what it means. :-)

All the best with the new CNC...

Cheers, Chris H.

Love the steel dino... Good stuff. :)

You could verify the metric vs inch issue by creating a job that cuts a 25.4 unit square outline and see if the machine appears to move 1 inch....

Just a thought.

Hi..

You're not outputting metric to an imperial machine are you? 2mm of travel is not a lot if you're expecting 2" :)

Just a thought.

Hi..

I imagine you could do a custom post processor up for vcarve and modify the drill cycle g-code?

Having said that, I'm not sure how you do that. I just had a look in the vcarve directory...

Updating progress incase anyone is following this. :-)

The machine is going well, and I've added a spindle ready / at speed input per this thread:
...

Just to round off this thread...

Using the code:

net spindle-ready <= parport.0.pin-12-in-not
net spindle-ready => motion.spindle-at-speed

In the custom.hal file is what I've gone with. ...

Well spotted Lee... I'd not made that link at all. I've only read the bits of the integration PDF I needed to test it.

Makes good sense though, so I'll wire it up properly and do a bit of...

Hi-ho,

At this stage I've just got an open collector output from the VFD which gives a 'reached frequency' indication. The examples for near that I've seen use the motion.spindle-at-speed a well...

It's got more options that I've had hot meals. :-) The trick being figuring out which one you want without getting too far down the rabbit hole. :-).


Anyway...

When I stopped searching for...

Arrrrr. :cool:

I thought you were, so was searching the LinuxCNC site for 'fin input' and variations thereof.

Not a worry, I imagine there is away to accept the input they probably just call...

Hi Al...

I've sorted the output from the VFD, but nothing is leaping out at me in the stepconf wizard to set up the input in linuxcnc.

Reading the spindle control docs on the LinuxCNC website...

Nicely done as well...

That's a whole lot of MDF. :)

Hi...

If not broken chains, do you have duplicate vectors in the deer?

Before I upgraded to vcarve I had problems with cut2D doing some keyring engraving that turned out to be duplicate vector...

Hi-ho,

I think I'll go for the hardware input option Al suggested, that way there's an extra interlock/safety on the spindle actually turning before it ploughs into the table. :-)

I had a quick...

Hmmmmmm.

Thanks for that. I'll have to read the VFD manual... Asside from skimming it before I imported the machine I've never actually done that. :-)

Cheers, Chris H.

It runs mid2cnc.py music better now that it's on LinuxCNC..

Super Mario Bros. CNC Music :-) - YouTube

:-)

Hi-ho...

A question for the room.

Is there a way to get LinuxCNC to automatically put a dwell/delay in after the M3? My old machine did, and I've got 300+ gcode files which I'd rather not have...

Photos... The app on my phone left them off...

Tada!

One C11 installed.

Motion, estop, home switches are 100% as wanted and probe works but have some funky issues with the gcode for that which I need to work through.

I'll think about...

???????

I'm sorry, but I don't follow either..

My first home made machine suffered many crashes** and that's what gave me the confidence to get the larger machine. Learning from my mistakes***...
