Mach3 under Vista / Re: A Blue Question sign in device manager win7 32

« on: March 02, 2019, 05:12:52 PM »

Go into command prompt with administrator rights and paste and add the below registers.

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

Restart the computer for the changes to take effect.

(I got this from post by another forum member)

Mach3 under Vista / Re: Win7 32 bits Mach3 with parallel port pulsing at 100K

« on: March 02, 2019, 05:06:31 PM »

Mach3 runs VERY WELL on WIN7 32bits with Parallel port(s).

Since I only have old versions of CAD software, I could load them all in win7 32 bits now.

I have to dual boot into Win 10x64 ONLY in the times I have to buy/upgrade to new CAD software that no longer supports 32bits OS.
I know that I cannot run Mach3 with a parallel port on 64bit OS but I can always get a external motion controller later.

Mach3 under Vista / Win7 32 bits Mach3 with parallel port pulsing at 100K

« on: March 02, 2019, 02:34:31 AM »

I have a spare new ASUS H110M-D motherboard on-board parallel port.
So I put in Intel I5 7600CPU 3.5GHZ and 16GB RAM and loaded up Windows 7 32bits to test.
(I intend to dual boot Win7 32bits and win 10 64bits)

MACH 3 parallel port pulse NOW can run at 100K Hz with “excellent” results with almost NO NEED for any “XP type Optimization Procedures”.

Motherboard:
ASUS H110M-D which has parallel port, USB3, VGA & HDMI ports on motherboard.
CPU:
I5 7600 3.5MHz with Intel 630 Graphics on CPU
ASUS has 32bits  VIDEO driver for Windows 7 ONLY (but not 8.1 nor 10)
Memory:
16GB DDR4  (I intend to dual boot win 7 32bits and latest “troublesome” Win 10 64bits on this same PC
500GB old HDD to be converted to new 512 SSD later.
Hurdles to overcome:
1.All Microsoft  Windows 7 update had to be initially done manually 2 times BEFORE automatic updates will work
2. Annoying “unsupported hardware'' popups can be silenced by removing 4 Updates that are installed.
3. 2 registry entries must be added for MACH3 to work with all latest window 7 updates
(it is in Mach3 forum)

UNFORTUNATELY
Time is running out to get Windows 7 and Motherboard and CPUs that will support Win7.

FAQs / Re: I should buy new controller.

« on: February 27, 2019, 02:18:00 AM »

I would FIRST swap the X & Y wires at the controller to check & rule out whether it is the wiring connection or soldering at the plugs or the x-axis Stepper motor that is faulty or not.

X on the chip may just mean that chip is to be connected to the x-axis.

JP-3163B ver. 3.9
Pin 1: Spindle on/off Relay 1(active low)
Pin 2: X Axis Step (active low)
Pin 3: X Axis Dir (active low)
Pin 4: Y Axis Step (active low)
Pin 5: Y Axis Dir (active low)
Pin 6: Z Axis Step (active low)
Pin 7: Z Axis Dir (active low)
Pin 8: A Axis Step (active low)
Pin 9: A Axis Dir (active low)
Pin 10:Estop (active low)
Pin 11: X Axis Limit Switch (active high) = when NC switch(es) open
Pin 12: Y Axis Limit Switch (active high)
Pin 13: Z Axis Limit Switch (active high)
Pin 14: Buffer Chips “Enable” controlled by computer if Jumper 3 is set to 1-2 position
Pin 15: Probe (active low)
Pin 16: Is supposed to turn Relay 2 on/off but is currently not connected in board.
Pin 17: PWM 0-10V for VFD Spindle AN1 (if jumper 4 is in default 1-2 position) active low
Pin 18: Gnd
Pin 19: Gnd
Pin 20: Gnd
Pin 21: Gnd
Pin 22: Gnd
Pin 23: Gnd
Pin 24: Gnd
Pin 25: Gnd

Jumper 1: 1-2 Internal 5V (default) ; 2-3 External Power Supply
Jumper 2: 1-2 Enable (by computer on pin 14) ON; 2-3 Enable (pin 14) OFF (default)
Jumper 3: 1-2 Air Cooling always ON; 2-3 Relay 2 by Computer pin 16 but 16 is currently NC (Default)
Jumper 4: 1-2 Analog 0-10V Pin 17 ON (default); 2-3 Pin 17 changed to digital Hi-Lo
Jumper 5: 1-2 Manual (handset?) On (Default); 2-3 Manual Off.

Microstep Mode (on each Axis X, Y, Z but A is on separate JP-1635A driver board)
K1    K2 
OFF OFF 1   = NO MICROSTEP 
OFF OFF 2 microsteps per step of 1.8deg = 0.9 deg
ON  ON  8 microsteps per step of 1.8deg = 0.25deg (default)
OFF ON  16 microsteps per step of 1.8deg = 0.125deg

K3    K4
OFF OFF   0% decay
ON OFF    25% decay
OFF ON    50% decay (default)
ON ON     100% decay

Perhaps low cost UC100 should do the trick.

General Mach Discussion / Re: tool diameter compensation

« on: July 26, 2017, 11:20:41 PM »

Try using G92 X0 Y0 at the beginning of the subroutine to temporarily offset the coordinates (defining the current position as x0 y0)

Then add G92.1  (to cancel the offset) just before M99 in the subroutine.
Then you can work in G90 mode throughout, I think.

i would try to avoid using G91 (relative mode) in the subroutine IF the main routine is G90 (absolute mode).
IJ is usually always relative as set in default general config of MACH 3.

PoKeys / Re: Spindle VFD feedback

« on: July 06, 2017, 04:58:34 AM »

Why? it would be redundant.
Since the spindle is a direct drive (no pulleys in between), RPM should = S Speed already.

You will need a tachometer detector that can generate 1 pulse per rev. This signal is fed into the index pin of mach 3.
There are lasers and hall-effect (magnetic) detectors but spindle is too small to mount anything reflective or magnet for the tachometer circuit.

The  450 Kjb parallel port card has only a PWM pin 17.
The Nowforever need Analogue 0-10V.
So your need a converter like
http://www.dx.com/p/maitech-pwm-turn-0-10v-digital-to-analog-module-green-318473?tc=AUD&gclid=EAIaIQobChMIidH98ZL01AIVkQQqCh0AsA4xEAQYAyABEgLK4fD_BwE#.WV3o2cAy_cs

Once you have Analogue 0-10V, you connect Analogue ground and  0-10V to aGND and AN1 respectively.  lower connection 1 and 3 from left on the Inverter.

You also need a pin that enables the PWM pin (probably Pin 1?) + digital ground. Top row  connection 1 and 5
Only 4 wires.

At inverter console change
P0000 set to 1
P0002 set to 2

PWM pin 17 must be  set to active low in Mach 3 otherwise you will have 10V (full speed) all the time.


PS: it might be cheaper to just change your BOB to a 5 axis BOB that includes Analogue 0-10V plus relay. Cost about $10
