CS-Lab / two wire inductive sensor
« on: March 09, 2014, 04:36:10 PM »
Going a bit forward in my Denford Triac conversion to mach3, I've begun to map the different sensors and switches.

As you may know I got the machine already taken apart with all the electronics in one box.
Nevermind that as I'm going to run it of a CSMIO/IP-S which should be in the mail next week or so :)

I've come upon the min/max switches and the reference inductive sensors.
I know of NPN/PNP type three wire sensors, but these are only two wire.

From what I can gather they are ohmic, meaning that contact induces high resistance.
Does that mean that they are not semi-conductive and does anyone know what voltage I can safely operate them on?


CS-Lab / Servo drive as main spindle
« on: February 19, 2014, 03:45:09 PM »

I'm trying to get a servo motor to be the main spindle on my denford triac retrofit.
The driver accepts step/dir as input so I've assigned it to port 5 on my CSMIO/IP-S under spindle -> special functions -> spindle axis. (attachment spindle-setup-csmio.jpg)

Input pins on the driver are:
PV (I guess enable?) connected to output5/pin 18
PP+ (pulse) connected to step5+/pin 12
PP- (pulse) connected to step5-/pin 25
PD+ (direction) connected to dir5+/pin 11
PD- (direction) connected to dir5-/pin 24

Where do I set so that output 5 goes high when the spindle is started (M3/M4)?


General Mach Discussion / Cannot move Z negative
« on: October 27, 2013, 10:41:35 AM »

I've been trying to mill a pcb today and ended up with some imperial (G20) gcode.
Now I cannot move the Z-axis in the negative direction anymore.  ???

My MPG only reacts to Z-positive.
If I enter in MDI, say G0Z-1, the machine goes into e-stop with the message "Limit Switch Triggered"

The only switches I have on the machine is reference switches of which the Z is also ignored.
Can't say about the others as Z is the first one being referenced.

I've attached my XML for the machine.

Thanks in advance!


CS-Lab / Shorting output pin for disabling gecko G251X
« on: August 06, 2013, 08:00:22 AM »
I'm currently wiring up my mill to a CSMIO/IP-S using geckodrive G251X's.
As opposed to the geckodrive G203V where the disable pin needs 5V to disable - the G251X disable pin needs to be connect to ground of the power supply.
I could do it with a relay, but I'd rather keep the setup simple.
Would changing polarity for a set of output pins do the trick?


General Mach Discussion / Spindle index on Optimum D280x700 Vario Lathe
« on: February 14, 2013, 10:58:34 AM »

After venturing down a blind path with modbus/arduino and an Optimum branded chinese encoder I'm at a stand still.
Well untill I figured out to take the signal from the display on the lathe and feeding that into an input pin on my breakout board.
Problem now is that the STrue value is 4 times the actual rpm, which is because of the sensor receiving 4 signals per rotation.

I thought I could make a brain that just divided the value, but that doesn't seem to be the case.

I'm fairly new at this, so I might go the wrong way about it  ???

Kind regards,

Modbus / Encoder for spindle true rpm via modbus
« on: February 10, 2013, 01:14:34 PM »
Hello  :)

I've had an Optimum D280x700 Vario CNC lathe for some time now and have been controlling it with Mach3 just fine.
Now I have to make a new draw bolt for my mill and for that I need to make a BSW thread.
So I went and bought the Encoder kit from Optimum and got the parts with absolutely no documentation.
I figured out the mechanics but now I'm stuck on the electronics.
The Encoder is Chinese OIS708-1024/Z3-5LD  and has 8 wires marked V+ 0V A A B B Z Z
Is there any way I can get this into Mach3 so I can make threads?
I'm not even sure modbus is the correct answer  ???

Kind regards,
