PoKeys / Re: 57E + cncaddon - DIR line is not working ?
« on: March 23, 2015, 11:06:28 AM »
Hi Hanermo

After studying to your provided information, You can simply connect your drive in this way

PoKeysCNCaddon (10Pin)   MCA808 X1 (DB9 male)
3  DIR   --------------------------->    1 DIR+
2  GND   -------------------------->    6 DIR-
5  STEP --------------------------->    2 PUL+
4  GND   -------------------------->    7 PUL-

PoKeysCNCaddon is a Sourcing device (European style), it refers to GND.
Meanwhile you are trying to connect it as Sinking device (Asian style) which refers to VCC.

Regards,
Weerasak

PoKeys / Re: PoKeys57E – Fast Encoder Problem
« on: March 21, 2015, 08:04:58 AM »
I also found more problem on plugin  version 3.1.47b and 3.1.51

(1) step per unit, if you put decimal point more than hundredths will cause motion problem and limit signal triggered, for example put number 400.1234, it seems that plugin will need more time to calculate step signal

(2) dual drive, may be because of problem (1) that makes master and slave not synchronize and result in jerking gantry.

Hi Matevž,

Here is the operation on channel 26, everything is OK. But on fast channels is Not Ok. Please find out.

Thank you,

PoKeys / PoKeys57E – Fast Encoder Problem
« on: March 13, 2015, 01:15:52 PM »
Hello All,

I’ve found a problem on fast encoder channels 1, 2 and 3. it always gives incorrect counts. I also have tried varies speed start from very low speed to high speed. It always gives extra plus and minus counts depend on direction of jogging.

Is this a firmware problem?

However, on ultra-fast channel 26 was OK, the counts was always correct.

The way I conducted the test is that. Hit Zero button for all axes. Turn on and off PoKeys57E the counters will reset to zero, Then Jog away from zero randomly, then hit Goto Zero button, Mach3 will command motor back to zero point.

The purpose of doing this, because I would like to use an encoder to feed back position of commanded position. In general Mach3 with parallel port, at Ports & Pins>Encoder/MPG, I assume that we can set scale value in Counts/Unit column and it will show feedback of  commanded position.

However, with PoKeys plugin, mapping an encoder1 to X encoder (DRO 29), The value of Encoder Position in tap Setting (Alt-6) will be the same as encoder counts which appears in status window of PoKeys Plugin.

Where can I set scale or Counts/Unit for encoder?

The feedback encoder is 1000 p/r and make a connection as shown in picture below, Plugin version is v3.1.51 (15.2.2015).

Pin mapping is here.
1 = 1.A
2 = 1.B
5= 2.A
6= 2.B
15=3.A
16=3.B
8=26.A
12=26.B

Thanks

PoKeys / Re: Wrong Direction Sending G-Gode, Jogging and homing works fine
« on: February 08, 2015, 12:05:58 PM »
Next Problem,

calibrating my machine...
setting steps per mm and backlash...

actually my x y and z axis should go by 640 steps /mm

I started with the X axis and did like 100 times the same stuff... homing the machine, moving it towarts the dial indicator (its axis is quite parallel to the X axis)
write down digits move another 5mm write down digits and go back to the position to get the backlash...

MY PROBLEM: in Motor Tuning I can not set steps per mm as I want to cause else my motor wont move properly or not a bit...

The strange thing is 639.4 works 639.5 as well 639.6 doesn't and so on... Mach3 seems to be picky about the digits, which makes no sense to me...

When I do the procedure with the settings screen and "Set steps per Unit", Mach suggests me 638.3233533 and asks me if I want to store this value.
After I stored it, the motor doesnt move.

What am I doing wrong?

Cheers

Has anyone had this issue and could advise some tricks?

Hi,

Sometimes xml file can be corrupted and put us in unknown situation. You can clone and start configuring from fresh Mach3Mill.xml again.

640 step per unit should be correct, not a fraction number.

Thank you for pointing it out,

Please consider to put this option in Pulse engine tab in Mach3 plugin also. Configure all options from one place, make it easy to use.

Currently, I only use PoKeys application for setting IP address, upgrading firmware and clearing all setup.

PoKeys / Pokeys57E and ChargePump
« on: January 14, 2015, 07:54:01 PM »
Pokeys57E with firmware v3.1.45, does not stop generating charge pump signal when it lost connection. Can this be fixed in future version?

Thanks
