General Mach Discussion / Re: CAT30 vs BT30 vs NMTB30 vs ????

Afraid not, all I know is the hydraulic pressure  of the Beavers drawbar is 900PSI and the cylinder is about 60mm ID but not certain on that.

Hood,

Do you know how much travel is required to release the tool?

Hood,

Sounds right.  Here's the reference I found on all the different tapers:

Any clue what pullstud tension these want?

Ok, so if I understand correctly...  They can be interchanged, sort of.  The tapers are the same, NMTB has a short cylindrical section, the others don't.  The main difference will be in the height of the pull stud, and how the flange keys to the spindle?  I don't know for sure which taper the spindle I'm looking at has, but I'm guessing it's NMTB, which appears to be the most common, right?

Are CAT30/BT30/NMTB30 the same, different, interchangeable?

General Mach Discussion / Re: Problems with display mode

« on: August 03, 2009, 10:26:48 PM »

Well I was able to figure it out. I watched the video tutorial and made a few changes. The table outline is a dotted line and not a solid line like in the video. It was not turned on by default. I also reinstalled the software without driver support. Another setting I used was selecting the Sherline half pulse check box. And I used loaded the road runner sample .tap file instead of one of the DXF files which was another mistake I made. Now I am able to see all elements clearly and the offsets work as expected.

I have a new problem: How you you jog the Z axis? The arrow keys only move the X and Y axis.

Z jogs with PgUp/PgDn

General Mach Discussion / Re: Pendant Setup

That depends entirely on how the pendant is interfaced to the system.  If it uses the game (joystick) port, then the standard Mach joystick driver should work.  If it's a keyboard emulator device, or connects to parallel port pins, it should be possible to make it work through keymapping and/or a modified screenset.  If it's serial or USB, then probably not, as that typically requires a custom plug-in.

Hi,

Pitch screw = 2mm
Bipolar 200 step motor
Gear ratio = 2:1 (screw gear : motor gear)
Metric

In full step mode:  200 * 2 / 2 = 200 steps/mm
In 1/2 step:  400 steps/mm
In 1/4 step: 800 steps/mm
In 1/8 step: 1600 steps/mm

General Mach Discussion / Re: Converting Step and Direction signal to CW/CCW

Go to Config->Ports&Pins->SpindleSetup.  In the top-left corner, you can define a CW output pin and a CCW output pin.

ok.  so i have step x on pin 2, dir x on pin 3.  when i arrow key in diagnostics, 3 pin goes 5v to the right, 0 to the left.  (actually, 0.07).

However, when i hook up my cable, the 13 pin is the one that shows that 'hot' then 'cold' behavior.

DOH.  looks like the cable is completely wrong.  gah.  Thoughts on rewiring the cable so pins line up from one end of the cable to the other?

That cable is completely wrong.   It's a crossover cable intended for connecting parallel ports on two PCs together (LapLink-style) to do file transfers.  What you need is a 25-pin straight-through extender cable.
