[Emc-users] emc gcode problem

2007-02-15 Thread Michał Geszkiewicz
Hello I often use variables in emc2. Problem is than they are zeroing after stop button click. Is there any way to avoid this or to extract variables from emc2 while it is in auto mode before is executed command emc.command.abort() witch clears the variables. Thanks, Michael

Hi Michael My understanding of this is based on EMC from several years ago. You will want to test this. If I added the variables to the .var file like this 10005.124 10011.3516 before startup of the EMC it would accept them in part programs and would save values there when the system

I'm using now EMC2 2.1 with axis interface. Configuration is writable. I'm also wonder if the *.var file is readed each time I press start button or once on start of EMC2. Thanks Michal Dnia 15-02-2007 o godz. 16:04 Chris Radek napisał(a): On Thu, Feb 15, 2007 at 01:33:59PM +0100, Micha?

Finally had a bit of free time to work on this. Still needs testing and more features but here whats there so far: 12 step gens. Each stepgen is 28 bit DDS + FIFO + preset/residue clear logic Step gens overlaid on basic I/O port, Step generators can be individually enabled, or I/O pins left as

[Emc-users] Gang Lathe

2007-02-15 Thread richard harris
Hello, Thinking of using emc to operate a gang lathe, before I attempted it was interested in hearing ideas on setting up tools with emc. I would like my g code to simply say t2 and emc to know that t2 is set such a distance from the home switch on the x axis. Thanks

Peter, Great news. Will you be able to intermix steppers and PWMs on a single board? If I understand correctly your statement on PWM, that should be adequate for my needs. For my immediate project, I need three axes of steppers and one unidirectional PWM (no encoder) with a frequency between 5Khz

Me, too. I'm looking at converting my lathe to a CNC gang lathe (sort of like the Omniturn). I will use EMC for it. By the time I'm done, I will be able to do what you suggest. (I don't know the current state). Since I've just begun collecting parts, though, I can't say when I'll be done. :-(

they are strictly talking about using quadrature instead of step-direction as the interface between the card and the stepper drive.. Instead of the direction pin designating which direction the stepper would go - it looks at which signal rises or falls first. Very noise tollerant. Same way
