General Mach Discussion / wizard setting incorrect default for g94

« on: April 15, 2016, 10:07:20 AM »

Hello All
I am using the wizards and they work well but for some reason it is always setting the
feed at g94.
I prefer g95-
how can i get the wizaed always to use g95 instead of g94?

regards

Thanks chaps-- Hmm yes i didnt think of the microstepping bit
I will look at the gecko page and try and glean as much as possible

How many steps per rev would be typical for a stepper like this??
 Then i can work out the resolution that i am likely to get

Just an aside-- Yes the steppers are very inexpensive now- but you know
the South African Rand has devalued so dramatically that everything has
become unaffordablly expensive. I remember when our currency was
R1.40 to a pound sterling. It is now usually over R20.00 to a pound.

Thanks for the advice anyway

Hello Chaps --
I am not in the least accomplished in electronics and electrical stuff

Firstly -I have heard that steppers have there most torque when running very slowly?
Is this correct.
Therfore am i right to assume that a direct connected drive will be the most powerful way of
connecting the stepper to the leadscrew??

I am attaching a picture of a stepper motor ( no names or labels on it ) and a picture of
my benck milldrill. Can anyone tell me if the stepper shown will be OK for connecting to the
mill drill shown by a direct drive onto a 5mm pitch ball screw?
the drive will be powering the left to right feed and the front to back feed
Would it be better to use a toothed belt and gear the motor speed down ? small pulley on
motor bigger pulley on lead screw??
All comments will be appreciated
And many thanks
Fred Evans

Hello Stephan--
When I changed to f per minute the problem went away and I was able to
finish the job i was on .
Then I had a gearbox failure so I havent used the machine for the last week
or so.
Please keep us informed
