General Mach Discussion / Tooling Offsets using the Tormach method

« on: October 11, 2010, 06:25:45 PM »

Hi
Video Address:  http://www.youtube.com/watch?v=_8apTgMTvjI&playnext=1&videos=srC9h9H00Ps&feature=mfu_in_order

I have  tooling holders by Tormach that I`m using in my DIY router. I have gone over
the details of tool offsets in the above video. At this time I do not have the Tomach dial indicator
mounted in a holder. As a substitute I used a long drill bit mounted in a holder.
I setup tool 1 i.e. a long drill bit as the datum tool. It was placed on 123 blocks.
I brought the spindle down to the top of the 123 block and set in Mach3 that point
as zero.
I then found the top of tool1 and got a measurement of 5.2766

Tool2= 5.2356

Tool3=4.3434

Tool4=2.2066

Tool5=4.1271

 

I then loaded my code into Mach3 and brought T1 down to the surface of the part.
I set xyz to 0.000
I manually moved the machine from the part to allow for a manual tool change.
I placed T2 in the spindle and ran the program.

Problem: Tool2 raised extremely high over the work surface triggering my Z limit.
I have no idea why the second tool raised so high when it was a bit shorter the T1
I have a clearance plane set for .2 above the surface. Still the tool seems to be moving
just too high.

General Mach Discussion / Tool offsets - newbie problems

« on: October 03, 2010, 04:45:03 PM »

Hi
First are there any good tutoials on this topic.
I have been attempting to setup my tool offsets. No luck so far.
I just noticed something strange  on the program run screen under Tool Info.
That when the code is running the second tool  2 is not displayed.
Why would this be? In the code I assigned tool numbers and I see them
in the G code.
Could this be the reason the second tool is not offsetting correctly?

General Mach Discussion / How to link three G320 for fault protection

« on: April 17, 2008, 08:15:24 PM »

Hi
I would like to wire all of my geckos so if one faults the motors must be re-set. Does anyone
have advice on setting up the wiring for this feature.

Hi
I`d like to test my two parallel ports to see if their working correctly.
What`s the best method for this type of test.

General Mach Discussion / Need troubleshooting help...servo runway problem

« on: February 24, 2008, 04:12:10 PM »

Hi

I started mach3 and the machine. As soon as the power is applied to the
system. All three axes took off on their own. I just did a mach3 driver
test and it seems to be fine. I`ve been using the machine with no
problems for a long time. I have not made any recent changes to the
Mach3 config file. I have the sound logic breakout board and the sound
logic encoder interface board.
I tested the encoder board and its recieving 115 volts and its
providing 5 volts at its marked terminals.
I want to test the parellel ports but an uncertain how to go about it.
Its diffcult to test the geckos because of the runaway problem. I`m
totally lost big time.

General Mach Discussion / A million dollars to the person that can help me.

Hi

I started mach3 and the machine. As soon as the power was on to the system. All axes took off on their own. I just did
a mach3 driver test and it seems to be fine. How to I fix this problem. I`ve been using the machine with no problems for a long time
without problems.I`m using machh3 version 2.6. I`m also using the sound logic encdoer interface for servos on my machine. Also, no
changes have been to the xml config files or any modifications to the wiring of the system. It would be great if I could troubleshoot
the control panel with system powered up. That`s a bit difficult to do when the power is applied and all axes want to crash into the
machine frame. Sometimes this DIY stuff is a big pain in the ass.

General Mach Discussion / Z axis direction

« on: September 04, 2007, 09:28:08 AM »

Hi all

I was having trouble with the z homing into the table. I reversed the motor and
that was sucessful. Now when I use the MPG Mode my z- and z+ are reversed.
I forgot where to change that setting. X- is down toward the table....is that correct.
Thanks Barry

General Mach Discussion / G-code not running

« on: June 15, 2007, 03:31:43 PM »

Hi

I just upgraded to a new servo on my Z axis. I can
jog all axes just fine. When I try to run G-code
the code will not run. I`ve tried 3 or 4 project
codes and the same problem occurs.
On the feed rate dialog there are Units/min it has
some strange text loaded -1.#J Trying to overwrite
the text by typing a new feed rate does not stay. The
strange text reappears.
Note: I`ve had problems with servo faults on the Z.
Today I changed the motor output from active high to
active low on the z axis only and it jogged fine ...not one fault.
The other axes are set to active high and they jog
with no faults. Is this a normal config. If I change
the Y and X to active low they will fault.

General Mach Discussion / Servo Questions

« on: June 05, 2007, 09:29:55 AM »

Hi All

I just installed a new 800 ozin servo on my Y axis. Its running great.
I did a test to compare its holding torque. I grabbed the timing belt
and to my surprise I could not move the belt. It has very strong
torque . The reason I mention this is the same test on my z axis shows
it takes very little pressure to make the servo break free. It seems
to have almost no detent torque.
This was a 360 ozin servo I got from Jeff Davies, its on a 24 volt
transformer. This axis had been a lot of trouble with servo faults.
I`m not certain if the motor is too small or its not tuned correctly.
I am considering getting another 800 servo and changing out the 360
ozin servo.
My other concern is all my servos will be on one 15 amp 54 volt power
supply.I would have (2) 800 ozin and (1)1100 ozin servo on the
supply. These motors were purchased from Dan Mauch.
