Chip,
Not sure what you see for a problem, but my observation is that in
g91 incremental mode(a model command) when you issue an X0 Y0 Z0
command, nothing will happen because you are basically telling the
motors not to move from their current position. In the 2nd half of
your program after the (G91)you have 7 lines where the motors are not
going to move and I suspect that you are expecting them to move.
Hope this helps out!

Hi:

Had to go away for week--sailing in the Bahamas!!!! Returned last night and downloaded my mail.

Life's Hell, but since I left I have not received any Digests--last one is is #2356--so either Yahoo knew I went sailing and is pissed at me--or they have stopped coming.

Anyone else not getting them???

Any ideas??

Thanks,

John

Hello Art:

Could the lookahead be set to low I have it at 60. I am running a
750mhz cpu and 25khz in mach3. And should I use enhanced pulsing.

Thanks,

Loads and runs here. What are your aiming at and what do you think is
the problem?

With 500+ posts a week it really helps to ask a direct question or, of
course, give us all some new information. Nothing to do with being new,
outer space etc. lots of guys are here to help and read every post with
interest.

John Prentice (as a moderator)

Back in late November we posted a special introductory price on the
new MP1000-THC digital interface and torch height controller. The
special was scheduled to be discontinued Dec 15th (or until we had
shipped 50 units) but we were delayed in our first shipments so we
extended the date until the end of January.

As of Feb 1st (next Wed) the special will be discontinued. We have
met our goal of getting through the backlog and shipping the first 50
units. If you are interested in purchasing an MP1000-THC under the
hundred dollar discount we urge you to do it before next Wednesday.

We do not yet have an on-line ordering method set up (running as fast
as we can(:-)) but phone orders are welcome or standard mail orders.
We will honor the special pricing on any thing postmarked before
midnight on Feb 1st.


The details of the unit are on our website at

This special is for the owners of MACH2 or 3 ONLY.

We will contunue to offer the combo deal of MACH3 and the parallel
port and cables listed on the website for several more months but your
best deal if you already own MACH is the specail listed above.

Sorry to post this on the list but we wanted to give MACH users the
benefit to save the money if they were thinking about it and not get
upset when the price goes back to normal next week.

Hi:

Multiplying this all out means 32000ppi.

I can't get good motion above 5-10 ipm in the
motor tuning dialog with 32000 ppi entered.

When I had the default 2000 ppi entered I got
good motions at what was indicated as 500ipm.
(But was really more like 30ipm since the actual
ppi was 32000)

Sounds liek your not retungin properly after changing the steps/unit..

It dawned on me that the engine can only do 25khz,35khz,45khz.
and that 1/8 stepping is causing the max rate to be limited
by the engine update rate. Is this correct?

Yes, BUT, at your setting of 32000, thats about .78IPs or 46IPM. The frequency is in steps/sec not minute..

If I drop my ppi to 4000 (200ppr * 20 tpi) by changing the
jumpers for full stepping will this raise my max feed and
preserve enough resolution to exceed the
accuracy of the machine by a sufficient amount?

Dont. Stay at microstepping. You wont top out Mach3 on a taig, cant be done I dont think..
You settings , no matter the steps/unit, should give the same motion. Having 2000 at 500IPM is the same pulses
as 32000 at 31IPM , their both at 16Khz output. This means as long as the accel and vel atre set properly, you should
see absolutly no difference in the motion. The motors should sound the exact same. Anytime you change the steps/unit, you have
to retune the motor vel and accel to math that size of step.. Other than that you should be fine..

Regards,
Art

From: "Tim" <luvindaddy@...>
Subject: Re: Whats the point with a Z bottom limitswitch ?

Hello Guys,
The main reason for "hard" limit switches is to keep the machine from tearing itself apart whenever it reaches end of travel (either extended or retracted). They are not normally designed to prevent the tool, tool holder, or spindle from crashing into the table, fixtures, or parts. This is why a "bad" g-code program can destroy so many different things..... ie. parts, tooling, or worse a machine!

Thanks, Tim Bostic

ps. That is why it helps when you can become a good programmer & machinist instead of an operator/button pusher.(See where the machine "thinks" it wants to go & stop it before total destruction!!)

You can always tell the "operator/button pusher" from the "cnc machinist/programmer" by the holes cut in the machines table.

Carl

It is the 20 tpi screws that are killing you top speed. Do your
steppers stall before reaching full speed. Most steppers are only
usable to about 1000 rpm before the torque drops off too much. Going
to full steps may not give you any more totrque depending on the type
of drive you are using. Full steps will produce rougher motion and in
general will stall at lower speeds than microstepping. A common set up
is 5 tpi scres with 10th microstep drives. This gives good speed and
resoluion.

Hi,
I'm new nad just setting up my motors.

I have a Taig mill with 20tpi leadscrews.
I have 200 step per rev motors (1.8deg)
My stepper drivers currently are set for 1/8 step.

Multiplying this all out means 32000ppi.

I can't get good motion above 5-10 ipm in the
motor tuning dialog with 32000 ppi entered.

When I had the default 2000 ppi entered I got
good motions at what was indicated as 500ipm.
(But was really more like 30ipm since the actual
ppi was 32000)

It dawned on me that the engine can only do 25khz,35khz,45khz.
and that 1/8 stepping is causing the max rate to be limited
by the engine update rate. Is this correct?

If I drop my ppi to 4000 (200ppr * 20 tpi) by changing the
jumpers for full stepping will this raise my max feed and
preserve enough resolution to exceed the
accuracy of the machine by a sufficient amount?

I figure at 4000 ppi if these occur at 25khz this gives
a 375 ipm max feed ceiling set by the mach engine.
(although the motors won't actually be able to do this.)
Is this how you calculate the limit set by the mach update rate?

4000ppi still gives .00025" resolution. Does this exceed the
inherent resolution of the Taig by enough to leave the machine
setting the precision limit and not the steppers?

How much better torque will I get with full stepping?

If I half step for 8000 ppi this would give a 'mach engine limit'
of 187ipm which I believe will still be higher than what the motors
can actually do and give me an 'electrical resolution' of .000125".

How does this tradeoff work? Does all of this sound right or am I
missing something.

Hi Jim:

The screens shoudl look pretty much the same, if not, use view/load layout and load the 1024.set file.

Softlimits are set by entering the machine coordinates at which you want your table to stop or trip an error.
Once set, you turn them on after you ref. Until you ref they dont mean anything. Once on (the LED is lit), then
any attempt to jog past softlimits will stop, and any Gcode that moves past them will trip an estop.

The G54 offsets are default when you start up, pressing any zero buttons will change them to zero the position ..ect..
to change G55, 56.etc.. you need to open the work offsets tabel and enter them, OR switch to that offset with G55..ect.. and then press the zero buttons at the appropriate spot on the tabel, the G55 woudl then be updated.

Thanks for the comments, the new few months will show an even better Mach package.. we're working on some exciting stuff for the future... ( in the top secret development dept. :-) ).
