Re: [Emc-users] Single Pulse Output?

Thank you John and Andy. I've got my machine working almost exactly the way I want: When my spindle is enabled/disabled I have a oneshot triggering a port pin connected to a modified wireless remote for my vacuum system. Now I just need to build a workaround for the ~4 s pulse I get on that por

Re: [Emc-users] Single Pulse Output?

A 1 s pulse, +/-0.25 s, with +/-0.25 s timing accuracy would be adequate. N.C. On 2012-Nov-11, at 20:09, John Kasunich wrote: > On Sun, Nov 11, 2012, at 07:44 PM, N. Christopher Perry wrote: >> Is there a way to have a parallel port output generate a single pulse on >> com

[Emc-users] Single Pulse Output?

Is there a way to have a parallel port output generate a single pulse on command? I have a vacuum system that requires a pulse to turn it on/off, and would like to have my machine turn the vacuum on automatically. N.C. ---

[Emc-users] Spindle Control on the AXIS Interface

I started experimenting with spindle control and have found some odd behavior. I added the example HAL content from section 2 of this page http://linuxcnc.org/docs/html/examples/spindle.html. Got a error when I launched AXIS. Removed this line from the HAL file, which cleared the error: net

Edge cure grades might address that issue. They are specifically designed for those sorts of situations. Check out Loctite UV cure epoxies. N. Christopher Perry On Oct 10, 2012, at 4:32, andy pugh wrote: > On 10 October 2012 03:53, Dave wrote: > >> I'd look into g

Re: [Emc-users] Gluing little balls

How about a light/UV cure adhesive? Look up Loctite 5055 or 5056. Drop the ball in, give a little squirt of one of these, then hit it with the light from a bunch of UV LEDs in the 320 nm - 420 nm range. These sorts of LEDs are readily available now for just over a buck each. N. Christopher

Igor, I don't have an answer for you, other than to check on how you've defined you trajectory planning accuracy outside of this routine. Why are you using two half circles? You could just send the cutter back to the starting xy location in a single G2 instruction. N. Christopher

Re: [Emc-users] Bridgeport Stepper Inductance

That great info. Thank you! If they were 1-2 mH in unipolar mode, then when parallel connected for bipolar mode operation they should be closer to 2-4 mH, which is just about right. I'll confirm this with an LCR meter. N. Christopher Perry On Aug 30, 2012, at 15:20, Steve Stallings
