great so now set to 64 steps at 25600 steps per
seems lovely

oh i see, its all about setting the machine for the speed you need rather than total speed = derrr i have set it too fast then
typical newbie to cnc, and having a sign cutting plotter on full chat = trying to speed it up all the time.
great

change the direction pin on the z axis to what though??
it says 8 at the moment?
enabled = tick
step pin 4
direction pin 8
dir low = tick
step low = tick
step port = 1
dir port = 1


oh, so I do simply double the steps per?

is it 'better to have more micro steps on the drives and a higher number in the steps per?

hello, still in demo mode.
the machine is an isel fb2 16mm with 5mm pitched threads
neama 3.1's bi-polar parrallel
drives are set 3.2 a and 2 micro steps
leafboy usb bob



only two issues!!!

draw a box 100mm by 50mm in corel, export it as a dxf to corel cad.
import that into lazy cam - make the g-code.
send it to mach3,
the problem is the machine moves a mere exact half, 50 by 25mm instead of 100 by 50mm
do i change the 'steps per' from 400 to 800?
velocity stays at 750?
acceleration 24
is it better to have 'more' micro steps set on the drives than 2?
i.e. if I have 2 steps at 800 steps per  - if thats correect?
can I have 20 steps at 8000
or is that not how it works?

ALSO, my Z axis is set up just as the X and Y axis are - they trun the corrcet way, but the Z turns the wrong way goes up instead of plunges, and goes down at the end of the box

is that a wireing issue? as I changed the a- and aaaaaaaa+ around and the b+ and b- around and it dint make any difference.
thank you please

p.s. who do I send the pay-pal to?

ok, I don't know how to use it yet



all me bits have lit up



got the demo working, non parallel, 64 bit vista

I just want to get some computer numerical control, can't seem to open that on screen wheel doofer and make the motor move.

will be buying a license soon, no funds in the pay-pal at the moment.

hello
SHOULD I buy a 0.8kw chinese spindle at 65mm diameter, instead of the 80mm diameter?

about to purchase............

is it a weight lifting issue on the 16mm/5 ball screws?

I don't think I am too concerned about the 20mm collet, as I suppose the max I am to mill is with 1/4'' - 6mm?
