A handy little program which will convert most units of measurement is available for free download here:-

I have not tested all conversions for accuracy but the ones I have used are spot-on. Thought this may be of interest to others.

Is there a version of JetCam available that will allow saving a .set file, commercial or otherwise.

In a word 'no'. ( please prove me wrong someone )

I'm using nema 23 277 oz. would I need a reduction?

I think that only you can decide that. If you could obtain a torque gauge to measure your required axis drive torque, then say multiply it by 2. If this figure is less than your available 277oz you should be OK without a reduction.

Perhaps others may have a better guideline than this.

Another possibility that may be worth investigating is that the tool is moving in it's collet.

Hi Brian,

Seems you have overcome the problem with the Mylar Film melting and are producing usable masks with this material - congratulations on achieving this.

btw. the software download links on your website don't work.

Rob, would it be possible to increase the drive current (just slightly) to your Y axis stepper (do you have adjustment on your driver card for this) ?.

There have been questions on this controller before and others have mentioned lack of information from the vendor.

For this controller Mach is configured to use the following parallel port pins:-

Motor outputs:-
x step 2
x direction 3
y step 4
y direction 5
z step 6
z direction 7

Input signals :-
e stop 10

Limit switches:-
x 11
y 12
z 13

Hope this helps.
