General Mach Discussion / Chinese BOB output 3 wire to MRJ2S' input!
« on: December 12, 2020, 11:49:04 PM »
Hi,
    I came across this video:
https://www.youtube.com/watch?v=iRAKprcp_Gw
Looks like a chinese breakout board:

open attachment

output Step/Dir and common (3 wire) to the input of MRJ2S CN1A, how is this done?
A while ago I had to use a couple of SSD in between the BOB and MRJ2S but this video make it look so simple, I know also by adding a 4.7K resistor between port 2 of the BOB then to MRJ2S CN1A would work too, can anyone explain the wiring in the video?

Thanks,

General Mach Discussion / BVB25L Headstock upgrade advise.

Hi all, Long time!
I'm thinking of upgrading my BVB25L lathe headstock to something like this:

Here's my lathe:


There are gears inside the headstock, would it be easier if I re-build the headstock?, please advise.

Hi again,
             Where do I wire the "hold off" of CSD205-H to which terminal of PMDX?


THX,

Thank you guys!.
Will run the DriverTest.exe first the jog to see I the stepper motor turns, and of course with dip switch 8 on.
If if still does not turn, will change the ZoS to Win7 32 bit.

Ok, win7 32bit or below, got it!.
How to determine if the PC LPT is real or not?, I had checked the device manager—-> LPT1—>property—->resource—>0x378.
Let me switch to Win7 32bit then see what happens,

Thx

Hi TPS,
          The alternative power is supplied by a adaptor of 12v 2000mA.
The stepper driver is a CSD205-H (a Chinese driver):
http://www.1111motor.com/download/CSD205.pdf
The LED of the step/dir stays green solid when I jog.
About the pararell port I’m getting a feeling that there’s no signal coming out from the PC lot. This PC is win 7. I then swap to a 2nd PC win 10 OS still cannot jog the motor, could it be the PMDX board?

Hi all,
        It has been a while since my last visit, how are you all?
Ok, I’m facing some difficulty making the stepper motor turn using PMDX122, here are some pics of the PMDX, stepper driver and Mach3 screenshot:

Can someone please point out if the jumper settings on Pmdx122 are correct?
