Unfortunately, this project has been progressing at a crawl. Life gets in the way projects sometimes, as I'm sure y'all are aware. Some might remember me asking a bunch of questions in an earlier post. I got all my new stuff in around the beginning of June, except for the computer, which was an old hand-me-down. It was just like Christmas |

| These are my first 3 attempts to run some code (sent to me by a friend) and see that everything works. The first one, I didn't have a V-bit to cut, so i just used a 1/4" flat endmill (yeah, I couldn't wait till the next day to get the right bit, ha). I forgot to rename my license file, so it was stopping after line 500. The second one was with the v-bit on a piece of MDF I had in my scrap pile. This one showed that I had x-axis reversed and IJ mode set incorrectly. The last one looks pretty good, but I'm losing steps in the x-axis for some reason. I'm still trying to troubleshoot this issue. I'd like to give a special thanks to Jeff Birt who sold me all of the cnc equipment. His support has helped me get this far pretty quick, considering I've only been able to spend a couple hours a week on this project. |

| Sherline mode lengthens the pulses output by the parallel port. If you have a slightly marginal parallel port output then longer pulses might indeed help. If you have a really poor driver test then it probably would not help. Trying it is a really good idea. I have an older 1.5 GHz AMD (P4 vintage) in the shop that works fine with the G540 but can handle more than a 65 kHz kernel speed. I did not use Sherline mode as I was trying to do a head-to-head test with a SmoothStepper. I use a SmoothStepper though in daily use.

| Thanks. I will try it in that mode and see if it helps. Also, I haven't tried adjusting the kernel speed. I think it's still at the default 25kHz. Maybe I could try to adjust that and see if it helps?

| Thats what I meant. Lengthens pulses, any idea by how much? When I had troubles in EMC2, it was recommended to have a certain amount of pulses for the G540. When I changed the setting to make the pulses longer, I was gettting better results but everyone still urged it was an issue with my PC. I guess I was basically doing like a sherline mode... That looks much better. What was your time? -Jason |
