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 / Re: Tool offsets - newbie problems

« on: October 03, 2010, 05:07:00 PM »

Hi
I just changed the code to G43. Ran the code and still no luck. The Tool Infomation
never updated to show tool 2 had been used. I assume that is the function of Tool Info.

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.

General Mach Discussion / How to test a parallel port.

« on: February 27, 2008, 10:43:47 PM »

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.

I tried a older xml . I still have the same runaway condition.


Hi, Barry

May have a bad xml file.

Look in C:\Mach3\xmlbackups folder, It has backup xml's, Sort it by Date, Make a copy of the one that is just before the date you started having trouble.


Past it in C:\Mach3\ folder, Then re name it th Mach3Test.xml and load it, Give it a try.

With the boards your using there are a lot of special settings, It's probably the encoder interface board's settings your missing.

Thanks, Chip

One parallel  port controls the breakout board and the other controls the encoder interface card

Hi

The breakout board is bob campbells version 1.8 ...I believe. And also a sound logic
encoder interface board sold by rogers machine. Both boards require a parallel port
cable. The Geckos are G320 and they run on a 53 volt supply. The encoders are E2
250 line US Digital devices.

Hi
DC was working after I found a connection I must have bumped. I now have 54 VDC to the geckos.
I did a test of the encoder A and B referecing from the - encoder on the G320. I see a reading of 5.2 volts
I checked the Ground to 5 volt on the plug end at the encoder I see 4.9 volts
 
Note: Removed encoder interface card`s parallel cable from the machine. And the result
was the X axis does not runaway and I have a normal servo noise. If I attach both encoder
and breakout parallel cables I have a runaway.
