thank you all, I'll test and let you know

Re: angle calculation g68
Surely the angle is given by arctan. For small angles arctan and arcsin will give similar answers but they will quickly diverge as the angle is increased. Imagine going up 20mm and along 20mm, 20/20=1,? arcsin(1) = 90° but arctan(1) = 45°
The Gcode used for this function in Mach3 is ATAN. Examples of using this in Gcode can be found in the user manual under "Unary Operation Value". For the given example using Mach3. Decide on a parameter for the angle eg #51 for the angle and the angle will be given by #51=ATAN[3/20] . You can also use parameters for the Z move and the X (or Y) move. So if you have #52=3 and #53=20 you then have:
#52=3
#53=20
g01 z #52
g01 x #53
#51 = atan[#52/#53]
What you do with that value is up to you. If you want to you can set up a DRO on the screen using something like the program Machscreen to edit the Mach3 screens to display it during running of the program.

Hi
?
I finish a small macro which calculates the angle of the stock on the table
travel is ok
the distance traveled between the 2 points is 20mm and the withdrawal is 3mm
I'm stuck, what code used to calculate the angle??
THANKS

Re: uc300eth encoder for turning on mach3?
ok.. so if i use uc300eth in mach3.. for threading.. index pulse is needed.. do i need more?!

Re: uc300eth encoder for turning on mach3?
The UC300ETH Plugin for Mach3 can read an encoder and be used for rigid tapping.? This not common and not well documented, but there is a macro for it.? The Mach4 Plugin cannot process the encoder to lathe threading or rigid tapping.? ?For Lathe threading, The ESS or the PoKeys would do a great job on Mach4.? Mach4 has awesome features for advanced lathe operations. It is worth looking at.
Note also that the latest UCCNC (1.2116) also supports lathe operations.? You may want to consider that.
Do not worry about encoder signal coupling, we have hardware on our website for this is you need.

Re: uc300eth encoder for turning on mach3?
hi
i have a uc300eth... and a ess... with thd ess it works but uc300eth not... so i search for reason...
i dont know where bit i remember that i tead that the uc300eth need abz sensor?!

Re: uc300eth encoder for turning on mach3?
I had mach3 reading encoder pulses from a digikey 400ppr magnetic encoder straight on to the paralell port.. really cool stuff.. But there is a but.. it was slow throught the paralell port. Depending on the application it was usable..? I believe the ESS could read much much faster.

I've always believed that Mach3 only works with a single pulse encoder. It's how mine works. I think using an encoder was hoped for but they could not get it to work with a parallel port. They never worked on Mach3 much after it was decided to start again with Mach4 so it was never implemented. Single point threading works with a single pulse per rev within certain limits. You need a lathe with a powerful enough motor, good torque at the spindle and high enough inertia in the drive train to make sure the rpm does not drop during the threading process. A small lathe with not very good electronic speed control will likely cause problems. A lathe with back gear and a powerful motor will work fine for large diameter threads, smaller threads will be doable with higher rpm so back gear will not be needed. If you have a mini lathe you may have trouble.
Some external controllers may have the ability to work with an encoder but I know the Warp9 Smooth Stepper I have only works with a single pulse and I have used a controller that did not work at all for threading, but they have been further developed since then. I have never seen any posts by people saying they have got Mach3 working with an encoder so I think people who want that option probably go straight to Mach4 as this is a more recent development and there are videos of threading using Mach4, external controllers and encoders.

uc300eth encoder for turning on mach3?
good morning.
short question..
do i need for threading a single pulse encoder or ab z encoder when i use uc300eth with mach3???
thanks

Re: Touchscreen for welding station.
wow....? t'was another livetime ago......
I'd sub contracted to write the video portion of an industrial test station touchscreen used by the operator while testing airbag squibs.
The point here, they wore gloves that weighed nearly 11 pounds...(steel armored) to protect their digits when squibs exploded on the test stands rather than just responding electronically.
These guys regularly were busting the CRT touch screens with these massive glove as they really couldn't feel anything through them.?
short version... all you ned is a conductive pad through the glove, for contact and either will work just fine.
On that note.... many mfrs now make winter hand glove with just such a touch pad built in so phone touchscreens work with a gloved hand.
Depends on the environment, maint schedules, dust, and monkeys at the keyboard.......?? but 10 $300 15" touch screens will out last 1, $3000 industrial unit. BTDT supporting manufacturing automation for nearly 4+ decades.??

Hi Art, Joe is doing all sorts of interesting things.? He never did buy an ELS from me because he went straight to MACH3 on his lathe.? I enjoy visiting him and seeing whatever new project he is doing.? He’s a very busy guy. John Dammeyer ?

Re: Mach3 mill stopped in the middle of a job.
Don’t overlook the simple obvious dumb stuff. ? I once found a laser cutter I hadn’t used for a while was completely dead.? Had removed most of the electronics before realising I’d forgotten to turn off the emergency switch (which I always hit when finished).? Geez. ? Once at work a few of us spent a while diagnosing an unresponsive server, someone did ask “Is it plugged in?” (of course it was) but on checking I found the network cable wasn’t.? Gah. ? Tony ? ?
