And your cam software is... (crystal ball still have not returned from polishing) :D

Mach3 under Vista / Re: computer screen goes black when running mach3
« on: April 01, 2020, 03:52:36 AM »
Usually it's not a video card that makes problem, it's a processor.
Check the cooler on processor, thermal compound state, ...
When processor overheats it shuts down the computer.

Well, DoSpinCW/CCW will activate Output1, according to image that I attached. -> Enable signal
OUTPUTx (x is an output that is free on your BOB) -> Spinning direction signal.

Mach3 under Vista / Re: Can't get the jog pop up in mach3

Just download the 'latest' version of Mach3, well, not exactly latest, but version 062: ftp://anonymous:guest@ftp.machsupport.com/Mach3/Mach3Version3.043.062.exe

You will need 2 outputs from your BOB to control 2 relays.
First relay for CW/CCW and second for Start/Stop spindle.
Second, you can edit macros in your Mach3/macros/'your profile' folder named m3.m1s and m4 m1s
For example:

Code: [Select]
m3.m1s

ActivateSignal(OUTPUTx) ' switches ON direction control relay
DoSpinCW()                   ' switches enable relay

Code: [Select]
m4.m1s

DeactivateSignal(OUTPUTx) ' switches OFF direction control relay
DoSpinCW()                       ' switches enable relay


OUTPUTx is an output that you should define/enable in Pots & Pins

Attached you can see that CW and CCW can share same pin.

General Mach Discussion / Re: 32 bit

There is no 32-bit driver. Your Vista should be 32-bit NOT 6it-bit OS.

Hi Roger,
CPR stands for counts per rev. It is usually applied to an encoder.

If an encoder has 2500 lines, it sometimes called pulses/rev or PPR then because of the quadrature placing of the opto-detectors
it will have 10,000 counts per rev or CPR.

If you set your microstepping to 1/8th (recommended) then your steppers will rotate exactly one revolution when the drivers are presented with 1600 pulses or CPR.

Lets tackle the Z axis first. If the stepper rotates once with 1600 pulses and the z axis will advance 2mm, being the pitch of the ballscrew.
The 'steps per unit' value that you put on the Z axis tuning page will be:
StepsPerUnit=1600 / 2
=800

Easy!

Now the X and Y axes are not so simple. You say they are belts with a 24 tooth pulley? What pitch are the teeth on the belt?
For the purposes of demonstration I'm going to assume 3.15mm pitch (1/8 inch).
StepsPerUnit= 1600 (steps per motor rev) / (24 teeth x 3.15)
=21.16
You will have to round to 21 steps per unit.

Note this is very course resolution, every pulse will advance either the X or Y axes 1/21 (=0.05)mm. Is this what you expected or wanted?

Craig

No need for rounding in Mach3. Mach will be perfectly happy with fractional steps per.

It looks that your Mach3 is set to millimeters. If you are happy with speed/acceleration, set Mach3 to Inches and in motor tuning multiply Steps per, Velocity and Acceleration FOR EACH AXIS by 25.4 so, for X and Y:
Steps: 10160
Velocity: 118
Acceleration: 16

Max speed and acceleration are set in Motor tuning.

Could it be that you have very low acceleration?
