Hi, John

Hi, John

I downloaded your XML the problem is you need to change your slaved axis to C axis change the pin & port numbers and in slave Axis.

Forgot Motor tuning & Inputs C home sw also.

I ran into this problem with my waterjet cutter if I remember right.

Your probably getting good at changing things around now.

This should Doo-IT.

Hope it Helps, Chip

Hi, Lee

Sherline stepper motor wired Bipolar surplus control, It can be wired un-poler which is factory default

Try setting the Dir LowActive and Step Low Ac.. in ports & pins setup page one at a time some stepper control boards are sensitive to leading and trailing edge pulses.

If this helps you can change direction in Motor Home/Soft Limits setup page,the proffered way because of the leading/trailing issues

Sent you a PM

Just something else, Chip

Hi, Archie

I have an R2E4, it's wired 440 volts now, need to re-do the x-former for 220.

If your servo boards and power supply are in good shape, I think there + - 10 volt control,  there are several step-dir to +-10 volt boards out

there that will work.

If not ther Rutex makes some Hi-volt boards to replace your servo boards.

Hope this Helps, Chip

Hi, Lee

I'm using a sherline table but not there controller, If you want the dro to desplay properly you need to take the number of steps it takes to

make one complete turn of the table, divide it by 360, enter that value in steps per.

The Dia setting in settings page is for part size being cut, larger part slower feed rate, smaller part faster feed rate.

My settings (using 10 Micro-step control) are one turn 144072 dev by 360 = steps per 400.2, vel 2500, accl 500.

haven't checked the table for proper feed rates, But it has fast rotation.

Hear is a file set to .5 in settings page

Hope this Helps, Chip

Hi, Lee

I forgot to mention one more item, if you set the steps per to 1 deg. value, You will meed about 2500 vel. and 500 accl. values in motor

tunning.

Well anyway that's what it takes for my sheline table to run fast enough, set to miss steps then back off some for both settings.

Also set dia for A axis in settings page.

Thanks, Chip

Hi, Lee

In screen4, double click on 4 th axis dro, brings up dro control the text %+.4f controls the  window, the 4 is for 4 zeros to the right.

Haven't been able to find Doc's that exp. it's exact use though.

If your trying to calibrate in deg's then step's need to be number required to move 1 degree,  in motor tunning, steps per.

Thanks, Chip

Hi, Leed

In Config tool path select A Rotations Enabled, then OK for Deg. 4th Axis.

As far as the .0001, Art or someone stated that if your steps per aren't 10,000 or more it wont step .0001.

Hope this Helps, Chip

General Mach Discussion / Re: Servo following errors... Please, need some help.

« on: January 20, 2007, 12:59:58 PM »

Hi, Barry

Your Gecko's are 24 to 80 volts, your servo is good to 90 volts, it should be running off your 63 volt supply.

If your second servo is lower voltage your gecko current adjust will limit the volts to it also.

For a given resistance, voltage drives the current, higher volts higher current, lower volts lower current if there is no regulator.

Adjust your gecko's current to achieve a warm to the touch servo, after power is on for awhile.

Start with low current setting, adjust it up till your servos/steppers get warm, this should put you in the ballpark on your current limit

adjustment.

Hope this Helps, Chip
