Hi Mike:

Are you running in half or full step mode on the steppers??

They need to be turned on in the Config/state screen as well.

Re: Where have all my steps gone?

Mike Hammel
 

Great to here from you Art.

Before I expound on my problem, let me say that Mach 2 is a GREAAAAATTTTT program.
I would not be in "production" if not for you and Mach 2. You have been tremendous help and to that I say thank you.

My router is cutting foam. virtually zero resistance. I am running steppers @ 125 oz in torque. I have played around with motor tuning and thought I had everything tuned in. I am not sure what the numbers mean in the velocity and acceleration settings area under motor tuning. I know I have my y (problem axis) set at 1.5 velocity and 3 accel.

Maybe I am missing something simple. For now, I just re-reference every couple of parts. This keeps everything fairly accurate.

Thanks for any help,

Hi Mike:

There can be alot of reasons for losing steps. The fourth digit is not one
of them . Mach2 keeps track no matter the number of digits. If you'd like to
see 5 or 6 digits, then you need only change the DRO in the screen designer.
Trust me, the problem is other than mathmatical.
Now as to what this particular problem is, we need some testing I think.
400 steps per inch is VERY low and it may be an acceleration problem.
Resonance sets in easily in something this low, other problems can also be
accentuated by such a low count. Though this seems to be a normal resolution
for plasma work because theres no cutting torque required, pretty strong
motors are needed if actually cutting material with this low resolution. Is
this servo's or steppers. How many oz/inch if steppers?
Is it doing this in the air or only when cutting.? Only router (or
spindle) off or on?

Thanks,
Art

> If I run simple patterns, I don't loose any steps. If I do some
pocketing or engraving, I start loosing steps. I think (I'm probably wrong)
that I am seeing an accumulation of fractional missed steps because Mach 2
goes out to the forth digit and I am only able to go .0025 on the y and
.0005 on the x.

Do soft limits only work is limits switches are in place? I cannot seem to
activate them in the demo version. I hit reference all button when maching
is closest and in the right hand corner and can exceed what I put in the
softlimit table.



Thanks

Re: How to on a macro/

Ron Ginger
 

I think there is confusion on macros- Am I correct that are really two
places macros can go

1) into files with name like M###.m1s These are run by putting an M### in
your gcode program.

2) into the text box on a screen designer form. These must be saved in the
xml file, and are executed with some screen button is pushed.

Is this correct?

Where have all my steps gone?

Mike Hammel
 

I have a "missing step" problem. No, my porch isn't missing!

I am running a router with 2000 steps per inch on x, 400 steps per inch on y.

If I run simple patterns, I don't loose any steps. If I do some pocketing or engraving, I start loosing steps. I think (I'm probably wrong) that I am seeing an accumulation of fractional missed steps because Mach 2 goes out to the forth digit and I am only able to go .0025 on the y and .0005 on the x.

X rarely misses steps, y is the worse (400 steps per inch).

I have tried slowing y down to a crawl and I still end up missing steps.

Any Ideas?

Hi Matt,

Pretty much any joystick will work. If you want to use it with
KeyGrabber then it has to be USB. KeyGrabber will allow you program the
fire buttons to act as keys and will allow you to define the function of
each axis.

Thanks, but I think what I was really asking is how many total sensors will or should I use for my setup? Including limit and home switches.

Thanks again,

Thomas,

I like to use one limit sensor on each end of travel for my X and Y axis.
This is mostly for safety reasons.

On my Y axis, I ended up placing two targets and one sensor. Mach2 knows
the direction of travel so you can get buy with one sensor and a second
target for the inductive proximity sensor.

I just got through reading my last download of the manual and did a
search for macro/macros and did not find what I need. I am not a whiz
when it comes to the pc so be patient please.

How do you get a macro from notepad into the available macros file
