Title: high speed encoders
Post by: tantan on March 06, 2010, 10:34:33 AM

hi,

i have a pokey with an encoder connected to pin 1 and 2, nothing else is connected to it. if i configure it as a normal encoder every thing works well, but if i enable the high speed encoder option in the pokeys configuration screen the raw encoder values don't increase or decrease while the numbers 1 and 2 in the configuration screen blink while i am turning the encoder. i use the latest pokey software, i upgraded the firmware of the pokey and i use the latest mach version.

hope you help.

Hi!

Do not use fast encoders with Mach plugin yet.
New plugin which will support fast encoders is under work and shoiuld be released soon.

Fast Encoders IS supported in the latest Mach 3 plugin
I guess Boris and them are doing something in the firmware.

hi boris an scott,

i have tested the new software, pokeys seems to work if i open the raw values window i can see the values changing. if i have mach3 simultaneously started i see the value in mach3 (x-axis dro) changing but not i a right way; it is more or less fluctuating. if i close the raw values window of the pokeys software mach stops changing the values at all. if i open the raw values window in pokeys again the machdro starts to move again. if i check the pokeys screen in mach the mpg value changes between 0 and the value which is presented in the raw values pokeyscreen.

i hope i am clear in my explanation

thanks

I have sent Brian the Source code, so he can look it over, to see if I am screwing up the code in the plugin, (always a possibility), but I dont understand why it was working, and now it is not, and I havent changed that code since it was published a while back.

hi boris and scott,

i made a bit of progress. i had windows xp with servicepack 2 installed, i installed sp3. the mpg works now but not smoothly at all. i tried different settings in the calibration window but nothing gave good results.

Yeah, the MPG is sluggish. Almost the point of uselessness. I went through the trouble of rewiring my encoders to pins 1 and 2 and no increase in response. Hope this update fixes the problem. If not I will install a second parallel port card and connect the encoder to that.
