General Mach Discussion / Re: motor tuning menu wierd in machmill need a good XML file

Hmm.....,
I hope the wiring is approproate for 20 amps!

Yep, turn the variac and change the voltage down but the amperage does up and up until you burn the motor out. That is dumb!

While your changing the wiring you may want to consider that no matter what happens the lights stay on.
Long story short, was cutting a 4" thick plank of walnut wood, basement lights went out but the band saw kept running, didn't remember where the hands were..........

Next day rewired such that there willl always light!

F..en scary!
RICH

Noone said i was smart!!(grin)
Sounds like you had a bad experience.!
My house has 12/2 wire wrapped in cloth. I havent noticed any hot spots. But then once the control box is out, the room isnt going to pull 20 amps all the time.

I solved it!! Yea!!!
back in the ole' days of when i was programming and being a general nusiance to society, we used to play jokes on the other guys by turning down the electricity on their machines by use of a variac or variable tuneit downer(humor). As we lowered the power , the screen would scramble and the machine would crash. pretty funny HUH?We thought so too.To make a really long story more shorter:

I have a small house(and old) and the breaker was only 15 amp in the computer room. The one PC also has only a 250watt power supply which should have been enough. (and is now)
After hooking up everything , Tv on, 2 Pcs and a cnc control box, the amperage dropped and was causing mach 3/BOB/geckos all to go haywire.I didnt realize it until i noticed a flicker in the lights a few times, so i went out and put in a 20amp breaker and everything started working as it should. Who would have thought?
Story ends and I hope this helps many many more people.
And all you guys
Thanks for all your help and interest. Im sure im gonna have another big crop of problems, but at least this one is solved
Thanks Again

Have you tried setting Sherline 1/2 pulse mode in Ports and Pins ?.

Tweakie.

Did that already. no go with that
 Thanks.

Still trying to debug my system and make the motors work with something. Ive reinstalled M3 several times including each time cleaning out the registry and folders so it would be a clean install. I have only 1 motor hooked up to geck203v/c11g BOB for testing. All power setting are good. printer port good.
When I run MACHMILL with only port/ pins set, I cannot use the motor tune function. The motor just jerks and slips and sound like their full of dirt. When I go to ALt6 and run set steps, the motor runs smoothly. And Heres the WIERD PART (and now for the rest of the story...).

When I do go to motor tune and test motors normally with arrow keys. Steps per =2000/ vel=200/  accel=5 / step/dir pulse 2 it really bad
BUT!!! IF I MOVE THE ACCEL OR VEL SLIDERS WHILE PRESSING AN ARROW KEY (UP), THE MOTOR RUN SMOOTHLY!

 Anyone have an xml that works with gecko203v and c11g i can try.
maybe Im missing something to setup. Ive tried a ton of different ways.

General Mach Discussion / Re: set steps per unit works but not tuning motors. they are Jerky and slip

yeah i tried that. I started checking volts etc. (got a multimeter Yeah!)
 Using the c11g BOB and mach3, i tried motor tuning and the up arrow produced +5v but the down arrow produced 1-10 MA!! No juice going in reverse. Im gonna ask Arturo (cnc4pc) about that. I may have  a lemon. I unhooked every line and Gecko from the BOB and left just the one line hooked up. What Happened the 1st time was the up arrow lit up line 5 and the down lit up line 8. I wasnt wired to line 5! I was wired to 7/8/com.
So thats where i am. Im going to check here and see who uses what for BOBs and may get a different one.
also i found a program for checking the printer pins on the c11g. SO I know my printer port is working. It lights up the EN output lights.
SO ill have to wait for an answer from Arturo or buy a different BOB. and doI really need a BOB?

I am using a geared motor on the bench. Shouldnt it be consistent? I can understand a little variation if it isnt attached because of torque. But this is  extreme in nature to me. The motor sounds like is grating gears and then it speeds up a sec and goes back to a grating sound. But it one Mach menu it works fine. Ill hook it back up and see.
thanks.

Running stable ver of mach3. c11g bob ver8.2/ gecko 203v drivers. 6515 keling pS and keling motors. Parallel port is a pci card just to make sure of one problem. Cable is new. Everything has been checked many times. Ive tried all the settings from the msg board here and nothing is working.
Read msgs about jerky/slipping motors but couldnt find anything like this.
Problem:
Motors are jerky in tuning no matter what setting or speed. 1/2 pulse 1-5 step pulse port pins etc. No enables or e-stop.. everything is off except motor specs.
There was a couple of times that in tuning, the motor actually worked and i had a chance to tweak it (vel/speed). Once i tweaked it and "saved" and I IMMEDIATLY used the arrow keys to manually move the motor again, but it went back to jerky and slipping instead of a smooth rotation.
When I went to ALT6 setting and "set steps per unit" to like 20 as an example. it remembered the setting in tuning and rotated smoothly every time, no matter what number i inputed.
PC is winxp sp2 and a clean install with nothing but internet and mach3.
I dont have any more ideas as im not an electronics expert.
