General Mach Discussion / constant velocity issues

« on: April 25, 2010, 06:30:38 PM »

I have run mach3 for countless jobs, but recently had to change the computer , I used the original configuration .xml file, but the machine seems to not to work smoothly in constant velocity anymore and appears to behave like exact stop. the only thing i can think of is the new machine is a little slower (1.2 rather than 2.4 mhz) and wont calculate cv. Am i barking up the right tree?

Arturo,
can you explain the macropump thing, or can you send the one you have created i can look at.

hey arturod,
that makes total sense!!!!!
i presume 2 pins for step up and step down, so as you spin the knob it contacts the input pins repeatedly.
Does this digikey part need any mods or does it wire straight up? part number?

Is there a way of having a big analog style rotary feedrate dial control speed override in Mach 2/3 rather than up/down buttons?
Its a bit more hands on for optimising cut.

 also I have concieved a device that gets sticky taped to the surface of the work piece and listens to the harmonics of the vibrations, then varies the feedrate for smoother cut/ longer tool life in the same way a good craftsman 'feels' the tool. This would then control feedrate also.

General Mach Discussion / Automatic tool change for router table

« on: April 12, 2006, 06:24:46 AM »

 I would like to setup automatic tool change for my router table (vacuum collet style), i understand this is possible, so i wouldnt have to write the motions and relays into the actual g code. Instead preset tool change motions are some kind of subroutine( i presume).
Also what is meant by VB?
Can anyone shed some light on how i should start going about this.....

some motor drivers respond to negative trigger from positive volts low, some respond to 0v trigger from positive low, and some respond to negative trigger from zero low, this would explain the non function of reverse motor output, just a thought....when i was first learning this my entire router gantry arm (rack and pignion) ignored the limit switch and shot off the end of the machine and killed my stereo.
