New to ATC turret macro writing. need help please?

[suntravel]

Glad you found the info's you need.

Acorn is a powerful DIY CNC, if you dive into PLC and macro programming, you can do lots of things with it.

I read it (Acorn counter based tool turret with home sensor Instructions) wow! so simple. thank you very very much. it's exactly what I wanted. I understand it pretty good after reading the plc manual; it totally makes science. now I can just take my time and take it one step at a time and do a good job. I really like centroid acorn. my rigid tapping works soo good, and I like doing incremental tapping with fusion 360, but I have to make multiple tapping cycles, and assign each one a different depth, then put all of them into a folder, then individually apply them all to the next hole to tap in order for incremental tapping to work with the fusion 360 centroid acorn mill post processor to do incremental tapping. but it sure works perfectly with a 1.8kw servo spindle motor. I really like it. after I get this lathe turret done; I plan to do a mill atc with a carousel. IT'S LIKE PLAYING FOLLOW THE LEADER LOL READY OR NOT; HERE I COME LOL have a great day all, and I will let you know how it goes for me getting this turret to work.

Take a look at Peck Tapping cycle, needs just 10 seconds to program

There is no need for fusion 360 with 2 axis lathe parts. I bet it is faster with Intercon than fusion 360 to get a part running on the lathe

i have not tried lathe tapping yet. i use er20 and er16 tool holders on the mill, and I program lots of different operations to run in one program on the mill, and rigid tapping is bundled into one large program usually that's the way I do it. it has something to do with the fusion 360 mill post processor that makes incremental tapping not work.

I have not tried the intercon for lathe yet, I have still been doing upgrades on the lathe.

the lathe also has the 1.8kw servo spindle motor on it. I love it, it works great. I use a signal isolator to manage the floating ground in acorn for the 0-10 analog speed control, and i use relays to switch polarity of the spindle direction for the servo spindle motor. I am extremely happy with centroid. I'm a customer for life. I had so many problems for over 7 years messing around with mach 4 and pokeys and ess did not have rigid tapping, and I had no idea that centroid acorns rigid tapping would be so bullet proof spot on, I think it's because of the 10,000 ppr encoder on the 1.8 servo spindles that make it such a clean operation. but what do I know. all I know is I like it, and I cant live without it. LOL I've wasted a lot of money and time and hair falling out and being pulled out before going with centroid. they did all the work, and I get all the benefit. I cant ask for more than that. all my friends think I'm crazy because they cant understand my passion for inventing and building. but I; and only I alone know why I do it... (wispering) it's because I am crazy LOL yeah; crazy about having fun.

Setting up rigid tapping in Acorn is stupid easy, only to slow for my taste with default settings.

Works also with 400 and 1000 lines encoders and high speed.

Acorn is a very fast CNC, no compare to other DIY hardware and software

Go on and make great stuff with it, the faster your hardware can do, the better it works....

I am also building a turret with the aim to get under 1s from last to next chip including tool change.

ok now LOL I'm doing 200 rpm on my rigid tapping, and I've never tried it faster. I have never broke a tap, and I am afraid to break one because everything I tap is important to not scrap.

question: is slower safer? or would faster really forcefully make it's way better and less likely to break a tap?

I plan to use the 50% thread drill bit for my steel but I use 75% drill size for aluminum.

I have yet to try tapping in steel. also, I should have went with timing pullys instead of a 6 groove v belt, but I wanted a whisper quiet machine, and the timing pullys make more noise. but when tapping at 200 rpm; the belt has slipped before, I know this because the belt squeeks if it slips, and I hit e-stop and removed the tap by hand after freeing it from the spindle.

if I speeded up to 400 RPM, that might be better. also, it would be easier on my spindle motor bearings if I switched to timing pullys.

I like the phrase "stupid easy" your right about that. I should be working on machining some parts today but I'm happy and just goofing off and enjoying myself. you only live once. LOL

im in Oregon enjoying warmer rain today now that summer is almost here. it's good to chat with someone who likes the same things that I like. all my friends don't relate to me at all. they dont understand all this fun stuff.

I think this reply is a little over the top. just having fun. maybe I should not put that movie clip on here. I didn't know it would open up like that. it does have one cuss word in it. maybe it's inappropriate. if you think so, I can delete it.

Well I set up rigid tapping for min. 800 rpm and also never broke a tap.

Small taps up to M4 are running with 2000-3000 rpm on my mill and lathe...



But I must admit, my main job is chasing fractions of a second on production machines, and even on hobby I do not like slow running machines

wow, that is the best i've ever seen.

what's the largest tap you have used?

are you running a servo spindle?

are you using a brake with it so you don't overload the VFD/driver? because I noticed that you stop really quickly.

my servo spindle was fast like that when I first set it up, but I implemented an s curve tuning into it to just slow it just a little bit, but it is still really fast at reversing direction, but before i did that; it was pretty much instant from 3000rpm CW to 3000rpm CCW just like yours.

I thought it might be hard on the driver to leave it really fast at reversing. maybe I should set mine up like yours, and install a brake. that is supper fast.

I don't think the mill has ever error out when switching it back and forth from cw to ccw but the lathe has because it has a heavy chuck on it.

I like your setup. if I speeded mine up like yours then my belt would not slip because it would be flying!

supper cool. way to go!

[playerofpawns1]

oh actually you don't stop instantly, yep that's about what I have mine set to in the s curve. so all I would have to do is change my rpm and try it out huh?
