General Mach Discussion / Re: Breakout boards

« on: November 04, 2010, 04:14:37 AM »

Did you mean to send me to the CNC4PC C13? Their site says:
"Do not use this board for wiring Geckodrvies, these drives require 16 milliamps signals, the parallel port can only deliver 10 milliamps. Using this board for these drives can cause lose of steps and unreliable operation. "

Ooops sorry, my mistake. Looks like you have made a good choice with the C11G.

Because the gecko 320 already has opto isolated step and direction inputs it is usual to use a passive BoB similar to this http://www.cnc4pc.com/Store/osc/product_info.php?products_id=131
Often fitting two lots of opto isolators on step and direction (active BoB) has caused problems.

FAQs / Re: 3D pocketing ?

« on: November 03, 2010, 02:16:14 PM »

It is not a simple thing to explain in a thread on a forum. You really need to do some research to find all the in's and out's, so to speak and then ask specific questions rather than just ask for an instructional. 
On the positive side there is some info here http://www.google.co.uk/search?q=cnc+3d+pocketing&num=100&hl=en&client=firefox-a&hs=crN&rls=org.mozilla:en-US:official&prmd=vb&source=univ&tbs=vid:1&tbo=u&ei=aaXRTIPOOJCQjAeR6cyBDA&sa=X&oi=video_result_group&ct=title&resnum=4&ved=0CCoQqwQwAw
and there are many other websites regarding pockets in cylindrical work when you start to look.

btw. nice machines you have for your cue's.

General Mach Discussion / Re: TOUCH PLATE FOR FET-3

« on: November 03, 2010, 02:01:30 PM »

Hi Ron,

The touch plate information in  Members Documents is here. http://www.machsupport.com/forum/index.php/topic,10088.0.html

The way I have done it is shown (second half of page) here. http://www.cooperman.talktalk.net/files/17.htm

As I understand it the fet-3 only has 4 switch inputs brought out to the terminal block, as long as you have one spare input that is not being used, you could use that as your probe input.
Failing that you will have to locate an unused LPT (parallel port) input pin (10-13 & 15) and make a soldered connection to the underside of the pcb at the 25 way connector - unless you are very good at soldering this is not to be recommended.

Take a look at the above links, any questions, ask away.
This is one of those tasks that seems incredibly difficult until you have done it and then is seems just so incredibly simple.

I presume you have tried Output#1 active low checked / active low unchecked to see if this cures it ? (also check that no other outputs are mapped to pin 14).

Bill,

It can just be added and selected, or not, on startup (full instructions in thread).

I must admit that I don't understand all the in's and out's but it certainly seems a lot better with 3D (.stl) files.

Bill,

Have you read all the stuff on the Tempest Trajectory Planner, adjustable 'Jerk' etc. ?

I suppose this thread will wind up deleted as well? Buyer beware!

Somehow I don't think so.

Would be nice to know what went wrong with Max because they were, relatively speaking, a good company with a good product at a good price.

What is the ratio of one to the other as far as steps are concerned, is it a whole number ?
