General Mach Discussion / is this a known bug ?

« on: October 07, 2013, 03:57:45 AM »

hi, started up my machine the other day,(ver 066) and I found that when  programed with a G00 in a program or with midi, it didnt pick up either the velocity or acceleration settings and would attempt to go flat out from nothing,faulting the servos.However if you jogged it at rapid with the keyboard it did pick these settings up.
Caused quite a bit of head scratching untill I worked out what was going on. shutting the program down and re starting it cured the problem I didnt need to re-boot the computer. I have noticed freaky servo faults in the past which are begining to make sence now.

   Also If I re-install mach will it overwrite all my settings and toolchanger files?

Regards

General Mach Discussion / switch mode power supplies in series?

« on: February 02, 2013, 01:43:13 AM »

switch mode power supplies in series? can it be done? I remember being told that it could be if the psu had a pin to connect them which matched the frequencies? not sure ,i have got a box full of 24v 2amp smps that I would like to use though, and being able to link them for more amps or volts would be handy.

General Mach Discussion / unwanted creep in jog mode?

« on: January 15, 2013, 08:36:45 AM »

Hi my mach3 set up has developed a strange fault,occasionally while jogging (i have 2 mpg's fitted) an axis will creep on continuosly without having the handle turned? and it will carry on creeping at about 30mmpm until you hit reset. it is random apart from it generally happens when you have been doing alot of jogging,ie setting up,I have actually broke a couple of tools now so any help will do.
  thanks

General Mach Discussion / 6 axis robot arm thoughts.

« on: December 09, 2012, 06:04:50 AM »

Hi, im thinking of building a 6 axis robot arm.using nema 23 425oz steppers.
I am assuming mach3 will control it. Its for trimming vacuum formed plastic parts.
  What im thinking about is using the steppers on 1/2 step mode and bolting 100ppr encoders on the back of them,(giving 400 pulses per rev)
 I would like to do is then manipulate the arm by hand and record the pulses,which could then be somehow turned into machine commands, and replayed as a program.
Is this a goer or a non-starter? any thoughts?

General Mach Discussion / USB pendant button association ?

« on: November 23, 2012, 03:22:46 AM »

Hi,
  I bought a usb pendant:
http://www.ebay.co.uk/itm/180991754618?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

The jog keys I can assign through the hotkeys drop down and they work fine,but how do I find out the key number on the other keys?
I assume once ive got them I can assign the buttons on my screenset to them.
I have tried the keygrabber in test mod4e and it brings up the number on my keyboard,but dosnt do anything with the pendant? Although I dont have a clue how to set the keygrabber up!
 
   Any clues?

General Mach Discussion / ATC set up on milling machine?

« on: November 18, 2012, 06:53:57 AM »

I would like to build a 6 or 8 tool carousel ATC for my cnc'd BF 30.
  Fairly certain that to begin with ill use a torrmach/Hoss type gripping assembly (20 mm dia) that might be dogged for drive. But will be moving on to bt30 dogged in stage 2.
So I will need to know about indexing the spindle (maybe a opto sensed and a bicycle hydraulic disk brake actuated by air)?
Firstly what is the preferred method for the auto draw bar? belleville washers,air wrench,stepper motored I'm guessing ill need 2500kn for an un dogged and 1200 kn for a dogged?
   I have aquired a mitsubushi PLC if that is the way to go.
Mechanically/ electronics/pneumatics  im ok with building the mechanism, its the software side im going to struggle on.
Is there a definitive methodology on controlling an ATC from mach3?
 I do have friends that are wizz's at industrial control software but non have had anything to do with mach3.
Is there a Tutorial on the subject to get me started?

   Regards
