Sofar found Out the 2 Boards are at the moment not 100% compatiple.
Both Boards (Primo 3 Axis Opto) and (PicStepV4) have pullups at the Direction and step line! 10k at Picstep and 3k3 at Priomo's Board. You have to remove the 10K's on Picstep or the 3k3 on Primos! Otherwise RB0/1 on the Pic dont go 100% High or low!!
There is no +5V Connection for feeting the Pic16f628 or the Ops on Primos Board!
3. Parallelout Pinsetup on the 3Axis Optooutboard is divrend than the 4 Axis Outputboad! 2=xStep 3=xDir 5=yStep 6=yDir 8=zStep 9=zDir
4. You have to Switch the ribboncable on one Side. Otherwise the Pins are not 1 on 1 swicht! Be carefull because of the +5V (if extern feet- see point 2)
Found out all the thinks but still the Boards are not walking. Mabey someone got some Ideears.
THX for all Input!!
