Re: [Emc-users] LinuxCNC as laser cutter?

I've been inside Universal Laser Systems lasers. The laser doesn't have a throttle, just an on/off for the beam, and it's like this: The beam is about 0.008" dia, 1/125th of an inch. If you specify <100% power in vector mode, there is a Pulse Per Inch (PPI) factor used. If you specify 50%

Long thread but Ben created a Hal component to do rastering with the printer port. http://www.buildlog.net/forum/viewtopic.php?f=16=557 Sam On Sat, 30 Apr 2016 13:39:57 +0100 Sarah Armstrong wrote: > Linuxcnc works fine for Laser cutting , > > Laser

Re: [Emc-users] LinuxCNC as laser cutter?

Linuxcnc works fine for Laser cutting , Laser rasterising is a totally different matter , and needs to be looked at from a different perspective it also depends on how your laserbeam is switched , and the modulation type used . their is some limited information regarding rasterising on the Wiki

Re: [Emc-users] LinuxCNC as laser cutter?

If you have problem with PWM signal generation there are plenty of cheap micro controller development board available although protocols may be worse. I guess it could be an idea to search m-codes for "professional" laser cutters or maybe reuse codes usually used for spindle. 2016-04-30 3:48

Re: [Emc-users] LinuxCNC as laser cutter?

Rastering performance is an absolute requirement. Also, I've run into problems with machines (Universal Laser Systems, older ones at least) trying to do a whole lot of complicated vectors, or even just a circle. Or, a dotted line made it lose its mind. Poor trajectory planning on some

Re: [Emc-users] LinuxCNC as laser cutter?

Hmm. http://www.machsupport.com/forum/index.php?topic=27782.15;wap2 Looks like they're saying M62 actuall takes effect slightly before the G-code command executes, which could be a problem. How would you tie in requested power and modulate the power according to the instantaneous linear speed
