General Mach Discussion / M11/10 and E1p1/0 problems pls help
« on: April 25, 2011, 05:24:57 AM »
Hello everyone,
I purchased a Chinese laser that was missing the control. So having lots of experience with my router and Mills I decided to use Mach 3 as the control software. From mania nights of reading any information I could about controlling a C02 laser using mach the consensus is using M11/10. I set up the laser and wiring based off several examples I found which was using output pin nine polling to ground. I configured my post-processor in sheetcam to utilize m11/10 vs m3/5 everything works great when it works the laser seems to work with G00 and G01 with no problems but when there is a G02 move it only works half of the time? and usually will only work halfway through the file and start working towards the end. Out of frustration I tried the E1P1/0 commands which actually will work the exact opposite it worked flawless in the beginning but near the end of the file would just quit the moves would still happen however the output for the laser would stop. From the diagnostic screen mock itself stops outputting or controlling output one. Thinking this might be a computer or parallel port problem I've tried different kernel speeds from 25k to 75k with no change I then switched the output from negative side switching to high side switching this had no effect and the fact the diagnostic screen shows the output stopping midway through the file and the majority of the problems being with G02 moves I think there's something I'm just not setting up right in mach. has anyone had these problems or insight I'm at my wits end with trying to use mach for laser, I absolutely love it for my mill and lathe but definitely seems to have some issues with trying to use it for a laser.
Thanks
Chris
