I'm from France and excuse my imperfect English. I started from 8470 forum members machining http://www.usinages.com. I describe the current retrofit a laser WK40 with your DSP board HERE. I met some problems in connecting the cards. I validated the association will work with the following pin :
(Example for axis X)
[DSP]-(pin)--------------[stepping motor TB6560]-(pin)
PWM - (4) ------------- X STEP (2)
DIR - (3) ------------- X DIR (3)
5V GND(1) ------------- GND LPT (18-25)
(on board axis TB6550 : connect pin 16 with +5V (connector from the 5th)
For information: The Y-axis did not work. I checked the signals and observed values of 2 incoherent Schottky diodes SS14 (Bottom right of the barcode label) I have a desoldering and one diode were reversed compared to printing on PCB.
Thank you to inform the manufacturer about this non compliance.
Now the Y axis works.
My essays will interest a large Francophone community. Could you see if you do not offer the language interface in FRENCH? That would be welcome. I can translate the lines if you wish.
The manual is outdated and does not find the function of jumpers? I like to know.
